Continuous injection of an inert gas through a drill rig for drilling into potentially hazardous areas  

SciTech Connect

A drill rig for drilling in potentially hazardous areas includes a drill having conventional features such as a frame, a gear motor, gear box, and a drive. A hollow rotating shaft projects through the drive and frame. An auger, connected to the shaft is provided with a multiplicity of holes. An inert gas is supplied to the hollow shaft and directed from the rotating shaft to the holes in the auger. The inert gas flows down the hollow shaft, and then down the hollow auger, and out through the holes in the bottom of the auger into the potentially hazardous area.

Earth drill rig  

SciTech Connect

This patent describes an earth drill rig wherein an upwardly and downwardly moving drill-string-turning rotary table is rotated by a kelly bar connected at its lower end to a vertical drive shaft, the kelly bar being journalled for rotation in and fixed against axial movement with respect to a drill frame assembly and the rotary table being mounted for axial movement on and along the drill frame assembly. The drill frame assembly is pivotally mounted on a vehicle on a substantially horizontal axis for pivoting between an upright position and a substantially horizontal position for transportation. The improvement described here comprises the drill frame assembly pivot axis positioned below the lower end of the kelly bar and above the upper end of the vertical drive shaft, and a universal coupling connecting the lower end of the kelly bar and the vertical drive shaft the universal coupling comprising universal joints at opposite ends of an elongated slip joint connector and connected there-by for relative axial movement but driving coupling between the universal joints. The universal joints lie generally on a circle of which the drill frame assembly pivot axis is the center. The drill frame assembly can be moved between the upright and the substantially horizontal positions without disconnecting the kelly bar from the vertical drive shaft, the kelly bar being revolvable by the drive shaft through substantially the entire range of movement of the drill frame assembly.

Focus on rotary drill rigs  

SciTech Connect

This article discusses the drill rig, focusing on the rotary drill rigs. There are two principal drilling methods - rotary and percussion. In certain situations, percussion drilling is the most practical method, but for most applications, rotary drilling using the rotary-tricone bit with either steel-toothed cones or carbide inserts, is the common and accepted drilling technique. There are four principal reasons for a rotary drill rig: to provide power to the rotary-tricone bit; to provide air to clean the hole; to provide a life-support system for the rotary-tricone bits; and, to provide a stable and efficient platform from which to drill the hole.

Four rigs refurbished for West Africa drilling  

SciTech Connect

In April and May 1990, Shell Petroleum Development Co. of Nigeria Ltd. awarded Noble Drilling West Africa Inc. four separate contracts to drill oil and gas wells in the inland waterways of Nigeria. The contracted rigs included a shallow water jack up, the NN-1, and three posted barges, the Gene Rosser, the Chuck Syring, and the Lewis Dugger. The jack up was built in 1978, and the three posted barges are 1980s vintage. Three of the rigs have been idle for a number of years. The Shell Nigeria contracts required major modifications to the rigs before putting them into international service. Noble replaced or refurbished all major pieces of equipment in the drilling, power, and service systems on the rigs. Rig crews serviced all other equipment. A significant amount of general service piping and electrical wiring was replaced. Each rig also required additional motor control centers to support the new drilling and mud processing equipment. Alfa-Laval waste-heat water desalination plants and new sewage treatment units were installed on all four rigs. Because of the tidal variances and high silt conditions expected in the African waterways, all engine cooling systems were converted from heat exchangers to radiators. Rotary tables were made common on all rigs at 37 1/2 in. Noble had all traveling equipment completely inspected and modified as necessary. Strict attention was paid to certification and documentation of all equipment. Safety upgrades conformed to both Shell and Noble standards. Fire and gas detection systems were installed throughout each rig. Water and foam deluge systems were installed in the wellhead areas, and new foam systems and monitors were installed on the helldecks.

Electricity on the rig; part I -- electric applications on drilling and workover rigs  

SciTech Connect

This article points out that not only have electric motors replaced diesel engines and mechanical transmissions, but solid-state equipment is rapidly taking the place of rotary equipment in variable speed drivers and control systems. The SCR (silicon controlled rectifier) type of speed control has replaced other types by a large margin of acceptance on drilling rigs and has begun to be used on workover and service rigs. In most cases, electrical power is generated at the rig site with diesel-AC generators. On mechanically driven rigs, single diesel-generator sets operate to supply power for lighting and electrical motor loads. When high levels of power are required, such as on SCR-powered rigs, multiple generators are operated in electrical-parallel and each contributes to the total power required.

Rotary torque and rpm indicator for oil well drilling rigs  

SciTech Connect

Monitoring the torque applied by the rotary table to the drill string and the rpm of the drill string is provided. An intermediate adapter is positioned between the drill kelly and the rotary table. A strain gauge is attached to the intermediate adapter to measure torsional deformation and provide an indication of rotary torque. Transmission of torque data is accomplished by radio frequency transmission utilizing a transmitter on the intermediate adapter. A receiver is mounted to the side of the drill rig floor to receive and demodulate the torque signal. The intermediate adapter is rotating at the same rate as the drill string. Detection of the revolutions utilizing the changing R.F. Field strength is accomplished at the edge of the drill rig platform or elsewhere with a stationary sensor which doubles as the torque receiver. A highly directional torque transmitter antenna mounted on the adapter is used with the major lobe lying parallel to the rig floor and perpendicular to the pipe. By detecting the envelope of the radio frequency field strength, each rotation is marked by a peak. This enables continuous torque and rpm monitoring.

An energy-saving oil drilling rig for recovering potential energy and decreasing motor power  

Science Journals Connector (OSTI)

An energy-saving oil drilling rig is researched. A large accumulator is adopted in this rig to store the energy of the motor during the auxiliary time of lifting the drill stem and the potential energy of the drill stem when lowered. The equipped power of this rig decreases remarkably compared with the conventional drilling rig, and this rig can also recover and reuse the potential energy of the drill stem. Therefore, this rig owns remarkable energy-saving effect compared with the conventional drilling rig, and the energy-saving effect of the energy-saving oil drilling rig is also verified by the field tests. The mathematical model of the energy-saving oil drilling rig lowering the drill stem was derived and simulation analysis was conducted. Through simulation the curves of the drill stem lowering velocity and lowering displacement with time were obtained, and some conclusions were reached: (1) the heavier the drill stem lowered, the higher the lowering velocity is, and the shorter the lowering time is; (2) the smaller the displacement of the variable pump-motor, the higher the lowering velocity is, and the shorter the lowering time is.

42nd Annual Reed rig census  

SciTech Connect

The eleven-year trend of attrition in the US rig fleet slowed significantly this year as only 12 rigs, or less than 1%, left the available fleet. The number of rotary rigs available for drilling in the US now stands at 1,841. but for the 42-year history of the Reed Tool Co. Rotary Rig Census, the 1973 available rig count of 1,767 remains the record low for yet another year. The count of rigs active during the 45-day census period also declined since last year's census. The active count was down 4.5% to 1,221 from 1,279 in 1993. As a consequence, rig utilization fell to 66.3% in 1994, from 69.0% last year. Notably, a strong shift to gas from oil drilling has occurred. Of the 1,221 rigs active in the census period, 540 were drilling for gas on the last well vs. 356 drilling for oil. Compared to last year, this is an increase in gas drilling of 29% and a decrease in oil drilling 22%. (Rigs targeting both oil and gas totaled 325 in 1994.)

Laser Oil and Gas Well Drilling Demonstration Videos  

DOE Data Explorer (OSTI)

ANL's Laser Applications Laboratory and collaborators are examining the feasibility of adapting high-power laser technology to drilling for gas and oil. The initial phase is designed to establish a scientific basis for developing a commercial laser drilling system and determine the level of gas industry interest in pursuing future research. Using lasers to bore a hole offers an entirely new approach to mechanical drilling. The novel drilling system would transfer light energy from lasers on the surface, down a borehole by a fiber optic bundle, to a series of lenses that would direct the laser light to the rock face. Researchers believe that state-of-the-art lasers have the potential to penetrate rock many times faster than conventional boring technologies - a huge benefit in reducing the high costs of operating a drill rig. Because the laser head does not contact the rock, there is no need to stop drilling to replace a mechanical bit. Moreover, researchers believe that lasers have the ability to melt the rock in a way that creates a ceramic sheath in the wellbore, eliminating the expense of buying and setting steel well casing. A laser system could also contain a variety of downhole sensors, including visual imaging systems that could communicate with the surface through the fiber optic cabling. Earlier studies have been promising, but there is still much to learn. One of the primary objectives of the new study will be to obtain much more precise measurements of the energy requirements needed to transmit light from surface lasers down a borehole with enough power to bore through rocks as much as 20,000 feet or more below the surface. Another objective will be to determine if sending the laser light in sharp pulses, rather than as a continuous stream, could further increase the rate of rock penetration. A third aspect will be to determine if lasers can be used in the presence of drilling fluids. In most wells, thick fluids called "drilling muds" are injected into the borehole to wash out rock cuttings and keep water and other fluids from the underground formations from seeping into the well. The technical challenge will be to determine whether too much laser energy is expended to clear away the fluid where the drilling is occurring.

Field Demonstraton of Existing Microhole Coiled Tubing Rig (MCTR) Technology  

SciTech Connect

The performance of an advanced Microhole Coiled Tubing Rig (MCTR) has been measured in the field during the drilling of 25 test wells in the Niobrara formation of Western Kansas and Eastern Colorado. The coiled tubing (CT) rig designed, built and operated by Advanced Drilling Technologies (ADT), was documented in its performance by GTI staff in the course of drilling wells ranging in depth from 500 to nearly 3,000 feet. Access to well sites in the Niobrara for documenting CT rig performance was provided by Rosewood Resources of Arlington, VA. The ADT CT rig was selected for field performance evaluation because it is one of the most advanced commercial CT rig designs that demonstrate a high degree of process integration and ease of set-up and operation. Employing an information collection protocol, data was collected from the ADT CT rig during 25 drilling events that encompassed a wide range of depths and drilling conditions in the Niobrara. Information collected included time-function data, selected parametric information indicating CT rig operational conditions, staffing levels, and field observations of the CT rig in each phase of operation, from rig up to rig down. The data obtained in this field evaluation indicates that the ADT CT rig exhibited excellent performance in the drilling and completion of more than 25 wells in the Niobrara under varied drilling depths and formation conditions. In the majority of the 25 project well drilling events, ROP values ranged between 300 and 620 feet per hour. For all but the lowest 2 wells, ROP values averaged approximately 400 feet per hour, representing an excellent drilling capability. Most wells of depths between 500 and 2,000 feet were drilled at a total functional rig time of less than 16 hours; for wells as deep at 2,500 to 3,000 feet, the total rig time for the CT unit is usually well under one day. About 40-55 percent of the functional rig time is divided evenly between drilling and casing/cementing. The balance of time is divided among the remaining four functions of rig up/rig down, logging, lay down bottomhole assembly, and pick up bottomhole assembly. Observations made during all phases of CT rig operation at each of the project well installations have verified a number of characteristics of the technology that represent advantages that can produce significant savings of 25-35 percent per well. Attributes of the CT rig performance include: (1) Excellent hole quality with hole deviation amounting to 1-2 degrees; (2) Reduced need for auxiliary equipment; (3) Efficient rig mobilization requiring only four trailers; (4) Capability of ''Zero Discharge'' operation; (5) Improved safety; and, (6) Measurement while drilling capability. In addition, commercial cost data indicates that the CT rig reduces drilling costs by 25 to 35% compared to conventional drilling technology. Widespread commercial use of the Microhole Coiled Tubing technology in the United States for onshore Lower-48 drilling has the potential of achieving substantially positive impacts in terms of savings to the industry and resource expansion. Successfully commercialized Microhole CT Rig Technology is projected to achieve cumulative savings in Lower-48 onshore drilling expenditures of approximately 6.8 billion dollars by 2025. The reduced cost of CT microhole drilling is projected to enable the development of gas resources that would not have been economic with conventional methods. Because of the reduced cost of drilling achieved with CT rig technology, it is estimated that an additional 22 Tcf of gas resource will become economic to develop. In the future, the Microhole Coiled Tubing Rig represents an important platform for the continued improvement of drilling that draws on a new generation of various technologies to achieve goals of improved drilling cost and reduced impact to the environment.

40th annual Reed rig census  

SciTech Connect

This paper reports that declines characterize the 1992 rig census-in the number of available drilling rigs, in the number of active rigs, in rig utilization rate, in the number of rig owners and in industry optimism. The number of rotary rigs available for U.S. drilling fell by 255 units (11.3%) during the past 12 months, an attrition rate almost four times greater than in 1991. But despite the high attrition, only 59.7% of remaining rigs were working during the time the census was taken. Results of the 1992 census bring emphasis to an industry trend that became apparent in early 1991. The major oil companies, and many independents, continued their exodus form the U.S., and the remaining independents, which were hurt by low natural gas prices and unfavorable tax treatment of intangible drilling costs, were not able to pick u the drilling slack. Consequently, the past year has been disastrous for many U.S. drilling contractors, and the outlook for this industry segment remains bleak.

39th annual Reed rig census  

SciTech Connect

This paper reports on cutbacks in U.S. exploration and development drilling during the first half of 1991 which squeezed most of the optimism out of the drilling industry. Just how rough the year has been is underscored by the results of this year's rig census. The number of rotary rigs available for U.S. drilling declined by only 69 units (3%) during the past 12 months. But despite those withdrawals from competition, only 66% of the remaining rigs were working at the time the census was taken. Results of the 1991 census contrasted sharply with the stability and optimism that seemed apparent a year ago when 72% of the available rig fleet met the census definition of active. At that time, the mini-boom in horizontal drilling coupled with tax-credit- driven gas drilling led to a relatively high rig utilization rate and suggested that rig supply and demand might be close to an economically acceptable balance. However, it quickly became apparent in early 1991 that industry optimism was unjustified. Horizontal drilling began to drop and the lowest natural gas prices in 12 years triggered rapid declines in gas drilling. Although oil prices have been relatively stable and above $18 per bbl since January 1989, most major operators have concluded that a better return on investment can be had outside the U.S. and have drastically cut their domestic drilling budgets. These factors, combined with softened energy demand from the worldwide recession, further slowed U.S. drilling. The long awaited balance between rig supply and demand has seemingly slipped away. The 1991 Reed rig census describes an industry facing several more rough years. Details of this year's census include: The available U.S. fleet now stands at 2,251 rigs, down by 69 from the 2,320-unit total in 1990, and the lowest since 1976. Rigs meeting the census definition of active numbered 1,485, down 192 (11.4%) from the 1,677 active rigs counted a year earlier.

Hydrates represent gas source, drilling hazard  

SciTech Connect

Gas hydrates look like ordinary ice. However, if a piece of such ice is put into warm water its behavior will be different from the ordinary melting of normal ice. In contrast, gas hydrates cause bubbles in the warm water, which indicates the high content of gas in the hydrate crystals. The presence of four components is required: gas itself, water, high pressure, and low temperature. The paper discusses how hydrates form, hydrates stability, South Caspian hydrates, and hydrates hazards for people, ships, pipelines, and drilling platforms.

Delaware-Val Verde gas drilling busy  

SciTech Connect

Deep and not so deep exploration is under way in the southeastern Delaware and northwestern Val Verde basins in West Texas. Northern Terrell County is seeing a good agenda of Permian Wolfcamp development drilling in spite of testy gas prices. This paper reports that none of the drilling appears to be targeted to Ouachita facies along the Marathon portion of the Ouachita Overthrust, although oil production from several of those fields has been respectable. And a number of exploratory tests to 20,000 ft and deeper are under way or on tap in eastern Pecos County and Terrell County.

New depths with mobile rig  

SciTech Connect

Magee-Poole Drilling Company, a drilling contractor operating out of the south Texas drilling center of Alice, claims it operates the largest mobile drilling rig in the world. That is, it's the only wheel mounted portable rig that drills to 16,000 feet with 4 1/2-inch drill pipe - at least 3000 feet deeper than the previous mobile drilling rig ratings. The unit is designated the Ingersoll-Rand 1500 Series. What's more significant, according to co-owner Don Magee, is that the rig's portability gets the rotary table turning to the right sooner; it drills more footage per year. It rigs up in 1 1/2 days versus 3 to 4 days for a conventional skid type rig normally used at these depths. The unit's compact arrangement, with more components combined into single loads, makes possible its higher mobility. A conventional skid rig might require 25 to 30 truckloads to move the rig components, mud system, fuel and water tank, houses for utilities, storage and crew change, generators, and drill pipe. The new rig moves in anywhere from four to nine loads less. Further, the rig components weigh less without sacrificing durability.

Application of horizontal drilling to tight gas reservoirs  

SciTech Connect

Vertical fractures and lithologic heterogeneity are extremely important factors controlling gas flow rates and total gas recovery from tight (very low permeability) reservoirs. These reservoirs generally have in situ matrix permeabilities to gas of less than 0.1 md. Enhanced gas recovery methods have usually involved hydraulic fracturing; however, the induced vertical hydraulic fractures almost always parallel the natural fracture and may not be an efficient method to establish a good conduit to the wellbore. Horizontal drilling appears to be an optimum method to cut across many open vertical fractures. Horizontal holes will provide an efficient method to drain heterogeneous tight reservoirs even in unfractured rocks. Although many horizontal wells have now been completed in coalbed methane and oil reservoirs, very few have been drilled to exclusively evaluate tight gas reservoirs. The U.S. Department of Energy (DOE) has funded some horizontal and slanthole drilling in order to demonstrate the applicability of these techniques for gas development. Four DOE holes have been drilled in Devonian gas shales in the Appalachian basin, and one hole has been drilled in Upper Cretaceous tight sandstones in the Piceance basin of Colorado. The Colorado field experiment has provided valuable information on the abundance and openness of deeply buried vertical fractures in tight sandstones. These studies, plus higher gas prices, should help encourage industry to begin to further utilize horizontal drilling as a new exploitation method for tight gas reservoirs.

Thermal stress on bottom hole rock of gas drilling  

Science Journals Connector (OSTI)

Gas drilling has higher penetration than mud drilling. The greatest reason for this phenomenon with gas is that the gas is greatly cooled by expansion as it passes through the bit and thereby cools the bottom of the hole. The thermal stress at bottom-hole occurs during this process. The concept of thermal crushing of rocks is analysed in this study. The theoretical methods are developed to analyse thermal stresses and fragmentation induced by cooling of rock. Then, the numerical computation is conducted for the thermal stress equations with the numerical result simulated for the temperature field at the bottom hole to explain the reason of high drilling rates in gas drilling. Furthermore, an experiment was conducted to verify the theory. Therefore, the theories and simulated results in this paper have a guiding signification for best understand the technique and possibly to extend its economic advantage still further.

Comparing rig power transmission systems  

SciTech Connect

Installed power on drilling rigs has increased steadily since the inception of rotary drilling technology as a result of technical advances and the need to penetrate deeper horizons. Higher power levels for the pumps, rotary table and drawworks are also required for drilling deep wells within an economically reasonable period. Power initially available on a rig had been about 35 kW on average, whereas power values on modern rigs drilling ultra-deep wells are on the order of several thousand kW. The installed power values on modern drilling rigs, subdivided with respect to depth range, are shown. After safety, economic factors are of paramount importance to rig operators. Among these, which include low acquisition cost, long service life and ease of maintenance, a particularly decisive factor is high efficiency.

Cost analysis of oil, gas, and geothermal well drilling  

Science Journals Connector (OSTI)

Abstract This paper evaluates current and historical drilling and completion costs of oil and gas wells and compares them with geothermal wells costs. As a starting point, we developed a new cost index for US onshore oil and gas wells based primarily on the API Joint Association Survey 1976–2009 data. This index describes year-to-year variations in drilling costs and allows one to express historical drilling expenditures in current year dollars. To distinguish from other cost indices we have labeled it the Cornell Energy Institute (CEI) Index. This index has nine sub-indices for different well depth intervals and has been corrected for yearly changes in drilling activity. The CEI index shows 70% higher increase in well cost between 2003 and 2008 compared to the commonly used Producer Price Index (PPI) for drilling oil and gas wells. Cost trends for various depths were found to be significantly different and explained in terms of variations of oil and gas prices, costs, and availability of major well components and services at particular locations. Multiple methods were evaluated to infer the cost-depth correlation for geothermal wells in current year dollars. In addition to analyzing reported costs of the most recently completed geothermal wells, we investigated the results of the predictive geothermal well cost model WellCost Lite. Moreover, a cost database of 146 historical geothermal wells has been assembled. The CEI index was initially used to normalize costs of these wells to current year dollars. A comparison of normalized costs of historical wells with recently drilled ones and WellCost Lite predictions shows that cost escalation rates of geothermal wells were considerably lower compared to hydrocarbon wells and that a cost index based on hydrocarbon wells is not applicable to geothermal well drilling. Besides evaluating the average well costs, this work examined economic improvements resulting from increased drilling experience. Learning curve effects related to drilling multiple similar wells within the same field were correlated.

Tight gas sands study breaks down drilling and completion costs  

SciTech Connect

Given the high cost to drill and complete tight gas sand wells, advances in drilling and completion technology that result in even modest cost savings to the producer have the potential to generate tremendous savings for the natural gas industry. The Gas Research Institute sponsored a study to evaluate drilling and completion costs in selected tight gas sands. The objective of the study was to identify major expenditures associated with tight gas sand development and determine their relative significance. A substantial sample of well cost data was collected for the study. Individual well cost data were collected from nearly 300 wells in three major tight gas sand formations: the Cotton Valley sand in East Texas, the Frontier sand in Wyoming, and the Wilcox sand in South Texas. The data were collected and organized by cost category for each formation. After the information was input into a data base, a simple statistical analysis was performed. The statistical analysis identified data discrepancies that were then resolved, and it helped allow conclusions to be drawn regarding drilling and completion costs in these tight sand formations. Results are presented.

34th annual reed rotary rig census  

SciTech Connect

This article reports that the number of rigs active according to the 1986 census is 1052, which represents a decline of 1573 rigs from 1985 figures. This 60 percent decrease is the largest decline of active rigs in the 34-year history of the census. The 1986 census takers found 3993 rigs are available with the capacity to drill deeper than 3000 ft. The count has thus declined by 416 rigs (9 percent) from the 1985 total of 4409. Rig availability declined for the fourth consecutive year following nine straight years of fleet expansion (1974-1982). During the past four years, 1651 rigs have been removed from the drilling fleet representing a 29 percent decline from the record high number of rigs available in 1982. The 1986 decline in the available U.S. fleet is considerably less than what many industry observers had been anticipating. A larger decrease in the rig fleet has not been realized for a number of reasons.

For the sixth straight year, the number of rigs available in the U.S. declined. Five hundred and seventy-nine rotary rigs dropped out of drilling industry competition during the past 12 months as attrition forced rig supply closer toward balance with demand. Significant highlights of this year's census are: The U.S. rig fleet now stands at 2,752 drilling rigs, a 17.4% reduction from the census count in 1987. This is the largest percentage decline and the third largest absolute decline in available rigs in census history; The 1988 census active count was 1,532 rigs, up 10% over 1987; The 1988 census utilization rate was 55.7%, up from the 41.7% reported last year and a 110% improvement over the all-time low of 26.3% in 1986; Every region in the country reported a reduction in total available rigs. Each region also reported an increase in the active ring count with the exception of Ark-La-Tex; California had the highest utilization rate in the census (63.9%), and all regions reported a utilization rate greater than 50% with the exception of Ark-La-Tex, which reported a 45.5% rate; The number of rig owners declined 12% from 691 to 608. The decline in available rigs would have been greater, but owners brought back 226 rigs that had been dropped from previous census tabulations.

A review of light amplification by stimulated emission of radiation in oil and gas well drilling  

Science Journals Connector (OSTI)

Abstract The prospect of employing Light Amplification by Stimulated Emission of Radiation (LASER) for well drilling in oil and gas industry was examined. In this work, the experimental works carried out on various oil well drilling operations was discussed. The results show that, LASER or LASER-aided oil and gas well drilling has many potential advantages over conventional rotary drilling, including high penetration rate, reduction or elimination of tripping, casing, bit costs, enhanced well control, as well as perforating and side-tracking capabilities. The investigation also reveals that modern infrared \\{LASERs\\} have a higher rate of rock cuttings removal than that of conventional rotary drilling and flame-jet spallation. It also reveals that LASER can destroy rock without damaging formation permeability but rather, it enhances or improves permeability and that permeability and porosity increases in all rock types. The paper has therefore provided more knowledge on the potential value to drilling operations and techniques using LASER.

Drilling/producing depths; Two records and a revision  

SciTech Connect

This paper reports that record depths for natural gas or oil well drilling or producing continue to be rare occurrences, although one or two still come in each year. Records fell in Texas Railroad Commission (RRC) District 9 and in the California area of the Minerals Management Service (MMS) Pacific Outer Continental Shelf (OCS) in 1990. Deep drilling and production has traditionally been defined as well depths greater than 15,000 ft. Smith Tool reported that 9.4% of all active rotary rigs were dedicated to targets below 15,000 ft at the beginning of 1991. Deep rigs had dropped to 8.1% by year-end 1991, but remained above the 1989 and 1990 levels of 8.4 and 7.6%, respectively. In 1988 about 11% of active rigs were drilling deep at any given time.

Use of Cutting-Edge Horizontal and Underbalanced Drilling Technologies and Subsurface Seismic Techniques to Explore, Drill and Produce Reservoired Oil and Gas from the Fractured Monterey Below 10,000 ft in the Santa Maria Basin of California  

SciTech Connect

This project was undertaken to demonstrate that oil and gas can be drilled and produced safely and economically from a fractured Monterey reservoir in the Santa Maria Basin of California by employing horizontal wellbores and underbalanced drilling technologies. Two vertical wells were previously drilled in this area with heavy mud and conventional completions; neither was commercially productive. A new well was drilled by the project team in 2004 with the objective of accessing an extended length of oil-bearing, high-resistivity Monterey shale via a horizontal wellbore, while implementing managed-pressure drilling (MPD) techniques to avoid formation damage. Initial project meetings were conducted in October 2003. The team confirmed that the demonstration well would be completed open-hole to minimize productivity impairment. Following an overview of the geologic setting and local field experience, critical aspects of the application were identified. At the pre-spud meeting in January 2004, the final well design was confirmed and the well programming/service company requirements assigned. Various design elements were reduced in scope due to significant budgetary constraints. Major alterations to the original plan included: (1) a VSP seismic survey was delayed to a later phase; (2) a new (larger) surface hole would be drilled rather than re-enter an existing well; (3) a 7-in. liner would be placed into the top of the Monterey target as quickly as possible to avoid problems with hole stability; (4) evaluation activities were reduced in scope; (5) geosteering observations for fracture access would be deduced from penetration rate, cuttings description and hydrocarbon in-flow; and (6) rather than use nitrogen, a novel air-injection MPD system was to be implemented. Drilling operations, delayed from the original schedule by capital constraints and lack of rig availability, were conducted from September 12 to November 11, 2004. The vertical and upper curved sections were drilled and lined through the problematic shale member without major stability problems. The top of the targeted Monterey was thought to be seen at the expected TVD of 10,000 ft where the 7-in. liner was set at a 60{sup o} hole angle. Significant oil and gas shows suggested the fractured interval anticipated at the heel location had been penetrated. A total of 2572 ft of 6 1/8-in. near-horizontal interval was placed in the shale section, extending planned well length by approximately 470 ft. Very little hydrocarbon in-flow was observed from fractures along the productive interval. This may be a result of the well trajectory falling underneath the Monterey fractured zone. Hydrocarbon observations, cuttings analysis and gamma-ray response indicated additional fractured intervals were accessed along the last {+-}900 ft of well length. The well was completed with a 2 7/8-in. tubing string set in a production packer in preparation for flow and swab tests to be conducted later by a service rig. The planned well time was estimated as 39 days and overall cost as $2.4 million. The actual results are 66 days at a total cost of $3.4 million. Well productivity responses during subsequent flow and swabbing tests were negative. The well failed to inflow and only minor amounts (a few barrels) of light oil were recovered. The lack of production may suggest that actual sustainable reservoir pressure is far less than anticipated. Temblor is currently planning to re-enter and clean out the well and run an Array Induction log (primarily for resistivity and correlation purposes), and an FMI log (for fracture detection). Depending on the results of these logs, an acidizing or re-drill program will be planned.

This attempt was not successful in that the clean out tools became stuck and had to be abandoned.

Site Selection for DOE/JIP Gas Hydrate Drilling in the Northern Gulf of Mexico  

SciTech Connect

In the late spring of 2008, the Chevron-led Gulf of Mexico Gas Hydrate Joint Industry Project (JIP) expects to conduct an exploratory drilling and logging campaign to better understand gas hydrate-bearing sands in the deepwater Gulf of Mexico. The JIP Site Selection team selected three areas to test alternative geological models and geophysical interpretations supporting the existence of potential high gas hydrate saturations in reservoir-quality sands. The three sites are near existing drill holes which provide geological and geophysical constraints in Alaminos Canyon (AC) lease block 818, Green Canyon (GC) 955, and Walker Ridge (WR) 313. At the AC818 site, gas hydrate is interpreted to occur within the Oligocene Frio volcaniclastic sand at the crest of a fold that is shallow enough to be in the hydrate stability zone. Drilling at GC955 will sample a faulted, buried Pleistocene channel-levee system in an area characterized by seafloor fluid expulsion features, structural closure associated with uplifted salt, and abundant seismic evidence for upward migration of fluids and gas into the sand-rich parts of the sedimentary section. Drilling at WR313 targets ponded sheet sands and associated channel/levee deposits within a minibasin, making this a non-structural play. The potential for gas hydrate occurrence at WR313 is supported by shingled phase reversals consistent with the transition from gas-charged sand to overlying gas-hydrate saturated sand. Drilling locations have been selected at each site to 1) test geological methods and models used to infer the occurrence of gas hydrate in sand reservoirs in different settings in the northern Gulf of Mexico; 2) calibrate geophysical models used to detect gas hydrate sands, map reservoir thicknesses, and estimate the degree of gas hydrate saturation; and 3) delineate potential locations for subsequent JIP drilling and coring operations that will collect samples for comprehensive physical property, geochemical and other analyses.

HIGH-POWER TURBODRILL AND DRILL BIT FOR DRILLING WITH COILED TUBING  

SciTech Connect

Commercial introduction of Microhole Technology to the gas and oil drilling industry requires an effective downhole drive mechanism which operates efficiently at relatively high RPM and low bit weight for delivering efficient power to the special high RPM drill bit for ensuring both high penetration rate and long bit life. This project entails developing and testing a more efficient 2-7/8 in. diameter Turbodrill and a novel 4-1/8 in. diameter drill bit for drilling with coiled tubing. The high-power Turbodrill were developed to deliver efficient power, and the more durable drill bit employed high-temperature cutters that can more effectively drill hard and abrasive rock. This project teams Schlumberger Smith Neyrfor and Smith Bits, and NASA AMES Research Center with Technology International, Inc (TII), to deliver a downhole, hydraulically-driven power unit, matched with a custom drill bit designed to drill 4-1/8 in. boreholes with a purpose-built coiled tubing rig. The U.S. Department of Energy National Energy Technology Laboratory has funded Technology International Inc. Houston, Texas to develop a higher power Turbodrill and drill bit for use in drilling with a coiled tubing unit. This project entails developing and testing an effective downhole drive mechanism and a novel drill bit for drilling 'microholes' with coiled tubing. The new higher power Turbodrill is shorter, delivers power more efficiently, operates at relatively high revolutions per minute, and requires low weight on bit. The more durable thermally stable diamond drill bit employs high-temperature TSP (thermally stable) diamond cutters that can more effectively drill hard and abrasive rock. Expectations are that widespread adoption of microhole technology could spawn a wave of 'infill development' drilling of wells spaced between existing wells, which could tap potentially billions of barrels of bypassed oil at shallow depths in mature producing areas. At the same time, microhole coiled tube drilling offers the opportunity to dramatically cut producers' exploration risk to a level comparable to that of drilling development wells. Together, such efforts hold great promise for economically recovering a sizeable portion of the estimated remaining shallow (less than 5,000 feet subsurface) oil resource in the United States. The DOE estimates this U.S. targeted shallow resource at 218 billion barrels. Furthermore, the smaller 'footprint' of the lightweight rigs utilized for microhole drilling and the accompanying reduced drilling waste disposal volumes offer the bonus of added environmental benefits. DOE analysis shows that microhole technology has the potential to cut exploratory drilling costs by at least a third and to slash development drilling costs in half.

Research on Application of Steering Drilling Technologies in Shale Gas Development  

Science Journals Connector (OSTI)

Abstract HF-1 well of Pengye is a sidetracking horizontal well for shale gas development, the directional segment of the well is long, high requirements for well trajectory control of the directional segment in construction process. In allusion to the features and challenges of this well drilling, this paper introduces the application of slide steering drilling system and rotary steerable drilling system in this well, including analyzing all these tool basic principle, the characteristics and field application. The analysis shows that using different angel screw drill tool can meet the needs of increasing hole angle, steadying hole angle and adjusting the orientation; Adoption of EZ-Pilot steerable rotary system solves the problem of remarkable resistance and low degree of hole cleanness in long horizontal section, and satisfies the requirement of drilling and completion of the well. The system also shows the desirable performance in improving ROP and hole quality.

Abstract We present a long-term MINLP planning model for the development of shale gas fields. A key decision is the drilling/fracturing strategy yielding the freshwater consumption profile, which is critical in waterscarce regions with high cumulative demand for water. Results show that the model can help companies to reduce freshwater consumption by optimally planning drilling operations, at the expense of small reductions in the net present value of the projects.

Optimization Models for Optimal Investment, Drilling, and Water Management in Shale Gas Supply Chains  

Science Journals Connector (OSTI)

Abstract This paper provides an overview of recent optimization models for shale gas production. We first describe a new mixed-integer optimization model for the design of shale gas infrastructures. It is aimed at optimizing the number of wells to drill, size and location of new gas processing plants, section and length of pipelines for gathering raw gas, delivering dry gas and natural gas liquids, power of gas compressors, and planning of freshwater consumption for well drilling and fracturing. We also describe a detailed operational mixed-integer linear model to optimize life cycle water use for well pads. The objective of the model is to determine the fracturing schedule that minimizes costs for freshwater consumption, transportation, treatment, storage, and disposal.

Tax credits stimulate gas drilling without decreasing federal tax revenue: A win-win situation  

SciTech Connect

The long-term U.S. natural gas resource base (1300 + TCF) exists. The challenge is the timely conversion of that resource base to proved, deliverable reserves. Tax credits stimulate the transfer of the natural gas resource base to deliverable proved reserves by effective price enhancement and through the discovery, application, and dissemination of technology. Tax incentives act as net price increases to gas producers as long as all companies have roughly the same tax rate and all are able to utilize the credit. Tax incentives can thus be merged with gas price for statistical purposes. This paper demonstrates how the existence of the 29 credits stimulated drilling, increased relatively clean burning gas reserves, resulted in new technological advances and possibly increased federal tax receipts with no upward pressure on gas prices. New tax-stimulus mechanisms are introduced that will help ensure that tax credits both stimulate drilling and increase tax revenue.

Rig activity; 1991 is now the worst year on record  

SciTech Connect

This paper reports that U.S. rotary oil well drilling rig activity reached year-end levels above 1,100 rigs and averaged over 1,000 in 1990, the first increase since 1984. In 1991, however, operating rigs dropped once again, this time to an all time recorded low and once again, most forecasters erred on the high side. Rotary rigs running in 1991 averaged 862.8, a 14.4% drop below the 1990 activity level of 1007.8 rigs. The rig count, began at 1,068 in January, but fell steadily for the remainder of the year. A brief upturn at mid-year failed to hold up and the year-end increases in drilling we had come to expect since 1986 never materialized.

OPTIMIZATION OF INFILL DRILLING IN NATURALLY-FRACTURED TIGHT-GAS RESERVOIRS  

SciTech Connect

A major goal of industry and the U.S. Department of Energy (DOE) fossil energy program is to increase gas reserves in tight-gas reservoirs. Infill drilling and hydraulic fracture stimulation in these reservoirs are important reservoir management strategies to increase production and reserves. Phase II of this DOE/cooperative industry project focused on optimization of infill drilling and evaluation of hydraulic fracturing in naturally-fractured tight-gas reservoirs. The cooperative project involved multidisciplinary reservoir characterization and simulation studies to determine infill well potential in the Mesaverde and Dakota sandstone formations at selected areas in the San Juan Basin of northwestern New Mexico. This work used the methodology and approach developed in Phase I. Integrated reservoir description and hydraulic fracture treatment analyses were also conducted in the Pecos Slope Abo tight-gas reservoir in southeastern New Mexico and the Lewis Shale in the San Juan Basin. This study has demonstrated a methodology to (1) describe reservoir heterogeneities and natural fracture systems, (2) determine reservoir permeability and permeability anisotropy, (3) define the elliptical drainage area and recoverable gas for existing wells, (4) determine the optimal location and number of new in-fill wells to maximize economic recovery, (5) forecast the increase in total cumulative gas production from infill drilling, and (6) evaluate hydraulic fracture simulation treatments and their impact on well drainage area and infill well potential. Industry partners during the course of this five-year project included BP, Burlington Resources, ConocoPhillips, and Williams.

Developing safety indicators for preventing offshore oil and gas deepwater drilling blowouts  

Science Journals Connector (OSTI)

An important question with respect to the Macondo blowout is whether the accident is a symptom of systemic safety problems in the deepwater drilling industry. An answer to such a question is hard to obtain unless the risk level of the oil and gas (O&G) industry is monitored and evaluated over time. This article presents information and indicators from the Risk Level Project (RNNP) in the Norwegian O&G industry related to safety climate, barriers and undesired incidents, and discusses the relevance for deepwater drilling. The main focus of the major hazard indicators in RNNP is on production installations, whereas only a limited number of incident indicators and barrier indicators are related to mobile drilling units. The number of kicks is an important indicator for the whole drilling industry, because it is an incident with the potential to cause a blowout. Currently, the development and monitoring of safety indicators in the O&G industry seems to be limited to a short list of “accepted” indicators, but there is a need for more extensive monitoring and understanding. This article suggests areas of extensions of the indicators in RNNP for drilling based on experience from the Macondo blowout. The areas are related to schedule and cost, well planning, operational aspects, well incidents, operators’ well response, operational aspects and status of safety critical equipment. Indicators are suggested for some of the areas. For other areas, more research is needed to identify the indicators and their relevance and validity.

W. Canada boom to outshine second half U. S. drilling rise  

SciTech Connect

Drilling in the US will pick up slightly during second half 1994, but the first half to second half increase proportionally will not be as large as in Canada. Operators appear likely to drill nearly half as many wells this year in western Canada as they will drill in the US. Oil and Gas Journal estimates that drilling and completion spending will total $9.511 billion in the US this year, up about one third of 1% from spending in 1993. This steady investment is forecast despite a 2.3% drop in expected wellhead revenue to $72.53 billion. Highlights to OGJ's midyear drilling forecast for 1994 include: operators will drill 24,705 wells, compared with the 26,840 OGJ estimated in its early year forecast before the slump in crude oil prices; the active rotary rig count will average 810 rigs, 7% higher than in 1993; operators will drill about 3,684 wildcats, down from the 4,170 that OGJ predicted in January; the surveyed group of major operators will drill 3,091 wells in the US, including 246 exploratory wells; and drilling in western Canada will total a year record 11,531 wells, dwarfing the 4,654 wells drilled in 1992.

Scientific Objectives of the Gulf of Mexico Gas Hydrate JIP Leg II Drilling  

SciTech Connect

The Gulf of Mexico Methane Hydrate Joint Industry Project (JIP) has been performing research on marine gas hydrates since 2001 and is sponsored by both the JIP members and the U.S. Department of Energy. In 2005, the JIP drilled the Atwater Valley and Keathley Canyon exploration blocks in the Gulf of Mexico to acquire downhole logs and recover cores in silt- and clay-dominated sediments interpreted to contain gas hydrate based on analysis of existing 3-D seismic data prior to drilling. The new 2007-2009 phase of logging and coring, which is described in this paper, will concentrate on gas hydrate-bearing sands in the Alaminos Canyon, Green Canyon, and Walker Ridge protraction areas. Locations were selected to target higher permeability, coarser-grained lithologies (e.g., sands) that have the potential for hosting high saturations of gas hydrate and to assist the U.S. Minerals Management Service with its assessment of gas hydrate resources in the Gulf of Mexico. This paper discusses the scientific objectives for drilling during the upcoming campaign and presents the results from analyzing existing seismic and well log data as part of the site selection process. Alaminos Canyon 818 has the most complete data set of the selected blocks, with both seismic data and comprehensive downhole log data consistent with the occurrence of gas hydrate-bearing sands. Preliminary analyses suggest that the Frio sandstone just above the base of the gas hydrate stability zone may have up to 80% of the available sediment pore space occupied by gas hydrate. The proposed sites in the Green Canyon and Walker Ridge areas are also interpreted to have gas hydrate-bearing sands near the base of the gas hydrate stability zone, but the choice of specific drill sites is not yet complete. The Green Canyon site coincides with a 4-way closure within a Pleistocene sand unit in an area of strong gas flux just south of the Sigsbee Escarpment. The Walker Ridge site is characterized by a sand-prone sedimentary section that rises stratigraphically across the base of the gas hydrate stability zone and that has seismic indicators of gas hydrate.

Professional development of new rig supervisors a must  

SciTech Connect

This paper reports that because the number of drilling personnel has dropped dramatically over the last decade, many operators now face a shortage of competent rig supervisors. To be effective, the rig supervisor must develop a knowledge of drilling operations, apply optimization techniques to improve drilling performance, demand safe work practices, and protect the environment. Petroleum engineering degree programs and industry training programs can teach the rig supervisor specific technical and management skills; however, traditionally, the supervisor trainee shadows an experienced company man to learn how to direct a drilling operation. The success of this method depends not only on the skills and learning capabilities of the trainee but also on the trainer's time, motivation, knowledge, and ability to teach the skills necessary to direct drilling activities.

Rig activity; 1989 was the worst year on record  

SciTech Connect

This article discusses the quantity of oil rotary rigs running in the United States during 1989. Rotary rigs running in 1989 averaged 870, down 7.1% from 1988 and arguably the worst performance since anyone bothered to count. A quick check into dusty historical records reveals that in 1942 the rotary rig count averaged 761 (this was the result of a deliberate government policy of scaling back drilling). However, the number is misleading, because in the early 1940s cable-tool rigs were around 40% to 45% of the total operating at any given time.

Scientific results of the Second Gas Hydrate Drilling Expedition in the Ulleung Basin (UBGH2)  

Science Journals Connector (OSTI)

Abstract As a part of Korean National Gas Hydrate Program, the Second Ulleung Basin Gas Hydrate Drilling Expedition (UBGH2) was conducted from 9 July to 30 September, 2010 in the Ulleung Basin, East Sea, offshore Korea using the D/V Fugro Synergy. The UBGH2 was performed to understand the distribution of gas hydrates as required for a resource assessment and to find potential candidate sites suitable for a future offshore production test, especially targeting gas hydrate-bearing sand bodies in the basin. The UBGH2 sites were distributed across most of the basin and were selected to target mainly sand-rich turbidite deposits. The 84-day long expedition consisted of two phases. The first phase included logging-while-drilling/measurements-while-drilling (LWD/MWD) operations at 13 sites. During the second phase, sediment cores were collected from 18 holes at 10 of the 13 LWD/MWD sites. Wireline logging (WL) and vertical seismic profile (VSP) data were also acquired after coring operations at two of these 10 sites. In addition, seafloor visual observation, methane sensing, as well as push-coring and sampling using a Remotely Operated Vehicle (ROV) were conducted during both phases of the expedition. Recovered gas hydrates occurred either as pore-filling medium associated with discrete turbidite sand layers, or as fracture-filling veins and nodules in muddy sediments. Gas analyses indicated that the methane within the sampled gas hydrates is primarily of biogenic origin. This paper provides a summary of the operational and scientific results of the UBGH2 expedition as described in 24 papers that make up this special issue of the Journal of Marine and Petroleum Geology.

Drilling operations change gear  

SciTech Connect

Predicts that several technological developments (e.g. measurement-while-drilling tools, computer data-gathering systems, improved drill bits, muds, downhole mud motors, and more efficient rigs) will have a major effect on drilling operations in the not-too-distant future. While several companies manufacture MWD systems and most can boast of successful runs, the major problem with the MWD system is cost. Manufacturers continue to make advances in both turbine and positive displacement mud motors. As the life span of downhole mud motors improves, these motors can economically compete with a rotary rig in drilling certain straight-hole intervals. Prototype bit designs include the use of lasers, electronic beams, flames, sparks, explosives, rocket exhaust, chains, projectiles, abrasive jets, and high-pressure erosion. Because drilling fluids are taking a large share of the drilling budget, mud engineers are trying to optimize costs, while maintaining well bore stability and increasing penetration rates. Many companies are taking the strategy of designing the simplest mud program possible and increasing additives only as needed. Air and foam drilling techniques are gaining attention. Concludes that as crude oil prices increase and the rig count begins to rebound, attention will once again turn to drilling technology and methodology.

Well drilling apparatus  

SciTech Connect

A drill rig for drilling wells having a derrick adapted to hold and lower a conductor string and drill pipe string. A support frame is fixed to the derrick to extend over the well to be drilled, and a rotary table, for holding and rotating drill pipe strings, is movably mounted thereon. The table is displaceable between an active position in alignment with the axis of the well and an inactive position laterally spaced therefrom. A drill pipe holder is movably mounted on the frame below the rotary table for displacement between a first position laterally of the axis of the well and a second position in alignment with the axis of the well. The rotary table and said drill pipe holder are displaced in opposition to each other, so that the rotary table may be removed from alignment with the axis of the well and said drill pipe string simultaneously held without removal from said well.

New ultra-deepwater rig with dual rotaries will reduce costs  

SciTech Connect

The Discoverer Enterprise, a next generation, ultra-deepwater drill ship with a dual rotary system, will decrease drilling and completion costs by reducing bottom hole assembly (BHA) and tubular preparation time. Transocean Offshore received a contract from Amoco Corp. to build the ultra-deep floating rig and is scheduled to spud its first well in July 1998. It will generally work in water deeper than 6,000 ft. The rig design involves a new approach that addresses the overall well-construction process and equipment required to decrease significantly deepwater drilling time. The Discoverer is the first ultra-deepwater rig designed specifically for handling subsea completions and extended well tests. The paper discusses increased deepwater rig demand, rig construction costs, drillship design, well construction, development drilling, and cost justification.

DEVELOPMENT OF GLASS AND GLASS CERAMIC PROPPANTS FROM GAS SHALE WELL DRILL CUTTINGS  

SciTech Connect

The objective of this study was to develop a method of converting drill cuttings from gas shale wells into high strength proppants via flame spheroidization and devitrification processing. Conversion of drill cuttings to spherical particles was only possible for small particle sizes (< 53 {micro}m) using a flame former after a homogenizing melting step. This size limitation is likely to be impractical for application as conventional proppants due to particle packing characteristics. In an attempt to overcome the particle size limitation, sodium and calcium were added to the drill cuttings to act as fluxes during the spheroidization process. However, the flame former remained unable to form spheres from the fluxed material at the relatively large diameters (0.5 - 2 mm) targeted for proppants. For future work, the flame former could be modified to operate at higher temperature or longer residence time in order to produce larger, spherical materials. Post spheroidization heat treatments should be investigated to tailor the final phase assemblage for high strength and sufficient chemical durability.

Advanced Mud System for Microhole Coiled Tubing Drilling  

SciTech Connect

An advanced mud system was designed and key components were built that augment a coiled tubing drilling (CTD) rig that is designed specifically to drill microholes (less than 4-inch diameter) with advanced drilling techniques. The mud system was tailored to the hydraulics of the hole geometries and rig characteristics required for microholes and is capable of mixing and circulating mud and removing solids while being self contained and having zero discharge capability. Key components of this system are two modified triplex mud pumps (High Pressure Slurry Pumps) for advanced Abrasive Slurry Jetting (ASJ) and a modified Gas-Liquid-Solid (GLS) Separator for well control, flow return and initial processing. The system developed also includes an additional component of an advanced version of ASJ which allows cutting through most all materials encountered in oil and gas wells including steel, cement, and all rock types. It includes new fluids and new ASJ nozzles. The jetting mechanism does not require rotation of the bottom hole assembly or drill string, which is essential for use with Coiled Tubing (CT). It also has low reactive forces acting on the CT and generates cuttings small enough to be easily cleaned from the well bore, which is important in horizontal drilling. These cutting and mud processing components and capabilities compliment the concepts put forth by DOE for microhole coiled tubing drilling (MHTCTD) and should help insure the reality of drilling small diameter holes quickly and inexpensively with a minimal environmental footprint and that is efficient, compact and portable. Other components (site liners, sump and transfer pumps, stacked shakers, filter membranes, etc.. ) of the overall mud system were identified as readily available in industry and will not be purchased until we are ready to drill a specific well.

Gas hydrate occurrences and their relation to host sediment properties: Results from Second Ulleung Basin Gas Hydrate Drilling Expedition, East Sea  

Science Journals Connector (OSTI)

Abstract The Second Ulleung Basin Gas Hydrate Drilling Expedition (UBGH2) recovered various forms of gas-hydrate bearing sediments from 10 drill sites in the lower slope and basin floor of the Ulleung Basin. To characterize the gas-hydrate occurrences and the properties of the host sediments, whole-round core samples were taken from portions of recovered cores determined to be hydrate-bearing based on infrared (IR) scanning. These samples were further characterized by a variety of shipboard experiments such as imaging of the sediments with hand-held IR and visual cameras, measurements of pore water chlorinity within and around IR inferred cold regions in the core and grain-size analysis of pore-water squeeze cakes. Sediment compositions of selected samples were further characterized by X-ray diffraction and scanning electron microscopes during post-cruise analysis. The shipboard and post-cruise analysis results collectively indicate that the recovered gas hydrates mainly occur as 1) “pore-filling” type bounded by discrete silty sand to sandy silt layers, 2) “fracture-filling” veins and nodules, or 3) “disseminated” type in silt. In addition, minor but significant variation in gas hydrate concentrations were observed in diatomaceous silt where gas hydrates occur as “pore-filling” material in layers dominated by intact diatom frustules. Gas hydrate accumulations of “fracture-filling” type occur predominantly in regions where acoustic blanking features in the seismic record suggest gas migration from below the gas hydrate stability zone. Results from the UBGH2 core studies along with the analysis of similar samples from other expeditions, including those executed by the Ocean Drilling Program, the Integrated Ocean Drilling Program, and the First Ulleung Basin Gas Hydrate Drilling Expedition, greatly improved our understanding of lithologic controls on marine gas hydrate occurrences.

Regulatory capture by default: Offshore exploratory drilling for oil and gas

Abstract This article examines a form of regulatory capture that occurs when significant ambiguity exists regarding the environmental protection standards for new types of activities in the marine environment. To begin with, there is little research that categorizes the typologies of regulatory capture despite the ubiquity of the phenomenon. After a discussion of theoretical approaches to regulatory capture, I describe the operative definition and theory appropriate to the situation related to authorization of oil and natural gas production in Israel following the discovery of large offshore reserves in 2010. This approach, embodying several facets of existing typologies, is applied to decisions made authorizing construction of the Gabriella offshore exploratory drilling platform. The analysis highlights the nature of capture in the absence of clear agency jurisdiction over new activities located in offshore environs organized as temporal and spatial “vacuums”. I conclude that comprehensive marine spatial planning would result in less capture and the development of more capture-resistant regulations.

International guide: blasthole drills. [For blastholes  

SciTech Connect

This survey is a comprehensive, quick reference guide for surface mine operators. It details what rotary blasthole drill rigs are available around the world. The survey covers over 60 drills, each with a pulldown of about 125 kilonewtons (27,500 pounds). They are manufactured by companies in eight different countries. Drill rigs continue to grow in size and power as larger diameter blastholes increase drilling economy. With a range of units costing from approximately $200,000 to over $1,000,000 each, careful selection based on the requirements of specific mines is essential.

Kinetic inhibition of natural gas hydrates in offshore drilling, production, and processing. Annual report, January 1--December 31, 1994  

SciTech Connect

Natural gas hydrates are crystalline materials formed of natural gas and water at elevated pressures and reduced temperatures. Because natural gas hydrates can plug drill strings, pipelines, and process equipment, there is much effort expended to prevent their formation. The goal of this project was to provide industry with more economical hydrate inhibitors. The specific goals for the past year were to: define a rational approach for inhibitor design, using the most probable molecular mechanism; improve the performance of inhibitors; test inhibitors on Colorado School of Mines apparatuses and the Exxon flow loop; and promote sharing field and flow loop results. This report presents the results of the progress on these four goals.

X-ray Scanner for ODP Leg 204: Drilling Gas Hydrates on Hydrate Ridge, Cascadia Continental Margin  

SciTech Connect

An x-ray scanner was designed and fabricated at Lawrence Berkeley National Laboratory to provide high speed acquisition of x-ray images of sediment cores collected on the Ocean Drilling Program (ODP) Leg 204: Drilling Gas Hydrates On Hydrate Ridge, Cascadia Continental Margin. This report discusses the design and fabrication of the instrument, detailing novel features that help reduce the weight and increase the portability of the instrument. Sample x-ray images are included. The x-ray scanner was transferred to scientific drilling vessel, the JOIDES Resolution, by the resupply ship Mauna Loa, out of Coos Bay, Oregon on July 25. ODP technicians were trained in the instruments operation. The availability of the x-ray scanner at the drilling site allows real-time imaging of cores containing methane hydrate immediately after retrieval. Thus, imaging experiments on cores can yield information on the distribution and quantity of methane hydrates. Performing these measurements at the location of core collection eliminates the need for high pressures or low temperature core handling while the cores are stored and transported to a remote imaging laboratory.

Drill pipe management extends drillstring life  

SciTech Connect

Better handling procedures and frequent drill pipe inspections prolong the life of a drillstring. Crews taught to make quick visual inspections during rig moves and tripping can spot problem pipe early, thus preventing downtime or extensive repairs. Because of escalating costs of drillstring repair and replacement, Global Marine Drilling Co. organized a task force in March 1989 to define problem areas and establish new handling and maintenance procedures. The task force estimated that one 20,000-ft drillstring costs abut $600,000 and has a 7-year life span. Assuming the average rig life is 21 years, each rig will wear out three strings, totaling $1.8 million. The addition of $30,000/year for full rack inspections, repairs and downhole loss brings the total to approximately $2.4 million/rig over the 21 years. A contractor with a fleet of 25 rigs could expend $60 million on drill pipe-the construction cost of a well-equipped, 300-ft jack up rig. The task force reported on in this paper identifies four basic caused of drill pipe failures: Tool joint and tube OD wear, Internal corrosion, Fatigue cracking in the slip and internal upset areas, Physical damage to the tool joint threads and shoulders, and the tube.

Planning and scheduling a fleet of rigs using simulation–optimization  

Science Journals Connector (OSTI)

Some of the most important and expensive activities in the oil field development and production phases relate to using rigs. These can be used for drilling wells, or for maintenance activities. As rigs are usually scarce compared to the number of wells requiring service, a schedule of wells to be drilled or repaired must be devised. The objective is to minimize opportunity costs within certain operating constraints. This paper present the first stochastic approach to deals with the problem of planning and scheduling a fleet of offshore oil rigs, where the service time is assumed being uncertain. A simulation–optimization method is used to generate “expected solutions” and performance measures for rigs, as well as statistics about well allocation to rigs. The methodology can be used in two different ways – to schedule an existing fleet of rigs or to scale the size of the fleet – both contemplating the uncertain nature of the problem. The method’s expected results include performance measures for each rig, expected delay for a well to be served, the expected schedule of rigs, and a distribution of the well servicing order. The experiments based on real situations demonstrate the effectiveness of the simulation–optimization approach.

Because natural gas hydrates can plug drill strings, pipelines, and process equipment, there is much effort expended to prevent their formation. The goal of this project was to provide industry with more economical hydrate inhibitors. The specific goals for the past year were to: continue both screening and high pressure experiments to determine optimum inhibitors; investigate molecular mechanisms of hydrate formation/inhibition, through microscopic and macroscopic experiments; begin controlled tests on the Exxon pilot plant loop at their Houston facility; and continue to act as a forum for the sharing of field test results.

Drilling Waste Management Fact Sheet: Drilling Practices That Minimize  

NLE Websites -- All DOE Office Websites (Extended Search)

Drilling Practices Drilling Practices Fact Sheet - Drilling Practices That Minimize Generation of Drilling Wastes How Are Wells Typically Drilled? The conventional process of drilling oil and gas wells uses a rotary drill bit that is lubricated by drilling fluids or muds. As the drill bit grinds downward through the rock layers, it generates large amounts of ground-up rock known as drill cuttings. This section of the Drilling Waste Management Information System website discusses several alternative drilling practices that result in a lower volume of waste being generated. Oil and gas wells are constructed with multiple layers of pipe known as casing. Traditional wells are not drilled from top to bottom at the same diameter but rather in a series of progressively smaller-diameter intervals. The top interval is drilled starting at the surface and has the largest diameter hole. Drill bits are available in many sizes to drill different diameter holes. The hole diameter can be 20" or larger for the uppermost sections of the well, followed by different combinations of progressively smaller diameters. Some of the common hole diameters are: 17.5", 14.75", 12.25", 8.5", 7.875", and 6.5".

Model methodology and data description of the Production of Onshore Lower 48 Oil and Gas model  

SciTech Connect

This report documents the methodology and data used in the Production of Onshore Lower 48 Oil and Gas (PROLOG) model. The model forecasts annual oil and natural gas production on a regional basis. Natural gas is modeled by gas category, generally conforming to categories defined by the Natural Gas Policy Act (NGPA) of 1978, as well as a category representing gas priced by way of a spot market (referred to as ''spot'' gas). A linear program is used to select developmental drilling activities for conventional oil and gas and exploratory drilling activities for deep gas on the basis of their economic merit, subject to constraints on available rotary rigs and constraints based on historical drilling patterns. Using exogenously specified price paths for oil and gas, net present values are computed for fixed amounts of drilling activity for oil and gas development and deep gas exploration in each of six onshore regions. Through maximizing total net present value, the linear program provides forecasts of drilling activities, reserve additions, and production. Oil and shallow gas exploratory drilling activities are forecast on the basis of econometrically derived equations, which are dependent on specified price paths for the two fuels. 10 refs., 3 figs., 10 tabs.

Studies of geologic and geophysical data from the offshore of India have revealed two geologically distinct areas with inferred gas hydrate occurrences: the passive continental margins of the Indian Peninsula and along the Andaman convergent margin. The Indian National Gas Hydrate Program (NGHP) Expedition 01 was designed to study the occurrence of gas hydrate off the Indian Peninsula and along the Andaman convergent margin with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings. NGHP Expedition 01 established the presence of gas hydrates in Krishna- Godavari, Mahanadi and Andaman basins. The expedition discovered one of the richest gas hydrate accumulations yet documented (Site 10 in the Krishna-Godavari Basin), documented the thickest and deepest gas hydrate stability zone yet known (Site 17 in Andaman Sea), and established the existence of a fully-developed gas hydrate system in the Mahanadi Basin (Site 19).

Design of a novel drilled-and-grouted pile in sand for offshore oil&gas structures  

Science Journals Connector (OSTI)

Abstract New offshore oil and gas exploration has placed renewed emphasis on developing structures in relatively complex geological conditions. Due to the damaging nature of impact driving, traditional steel piles used to support jacket structures, are not ideally suited to specific soil types, such as carbonate sands. Drilled and grouted piles are commonly used to support structures in these soil conditions. This paper describes a novel drilled pile, which has been developed specifically to provide a cost effective installation process while maintaining the benefits of grouted piles. The installation process negates the need for temporary casing in weak soils and minimizes the number of offshore operations. In this paper, the installation methodology and post-installation performance of a large scale onshore field trial is described. The installation process was successfully demonstrated with a 1.9 m diameter test pile installed in fine sand to 17.7 m depth in under 3 h. The performance of the pile, as measured in a tension static load test, was shown to compare favorably with existing pile design methods.

U.S. drilling: Solid reasons for optimism  

SciTech Connect

One year ago, it was apparent that 1996 would be a better year for drilling in the US, primarily because 1995 performance was lower than expected due to low oil and natural gas prices in mid-year during the peak drilling season. Improving energy prices last year did spur more drilling, and a 2.9% increase to a total 23,560 wells is estimated for 1996. This year should show an even stronger increase, as the US gas market remains attractive and industry`s perception is that crude prices are stabilizing at higher levels, i.e., $20--25, instead of $15--20. The US rotary rig count followed the price up, from a low near 700 in January/February to slightly over 850 in December. To drill the expected wells this year will require an average number at the 850 level. Operators are investing more in their established oil producing areas to take advantage of improved cast flows. This will generate higher activity nearly everywhere. Gas drilling activity will be more geographical, depending on transport availability to surging winter markets and Canadian competition. The US, and world, hot spot is the Gulf of Mexico led by renewed activity on the shelf and an exciting new deepwater play. The expected activity surge has already taxed a service industry that has not yet upgraded its capacity from the long downturn. And spot shortages will temper the activity rise, particularly offshore. The following discussion and six statistical presentations detail these basic concepts and other key factors.

Relating horsepower to drilling productivity  

SciTech Connect

Many technological advancements have been made in explosive products and applications over the last 15 years resulting in productivity and cost gains. However, the application of total energy (engine horsepower) in the majority of rotary drilling technology, has remained virtually unchanged over that period. While advancements have been made in components, efficiency, and types of hydraulic systems used on drills, the application of current hydraulic technology to improve drilling productivity has not been interactive with end users. This paper will investigate how traditional design assumptions, regarding typical application of horsepower in current rotary drill systems, can actually limit productivity. It will be demonstrated by numeric analysis how changing the partitioning of available hydraulic energy can optimize rotary drill productivity in certain conditions. Through cooperative design ventures with drill manufacturers, increased penetration rates ranging from 20% to 100% have been achieved. Productivity was increased initially on some rigs by careful selection of optional hydraulic equipment. Additional gains were made in drilling rates by designing the rotary hydraulic circuit to meet the drilling energies predicted by computer modeling.

Geothermal Well Costs and their Sensitivities to Changes in Drilling and Completion Operations  

SciTech Connect

This paper presents a detailed analysis of the costs of drilling and completing geothermal wells. The basis for much of the analysis is a computer-simulation-based model which calculates and accrues operational costs involved in drilling and completing a well. Geothermal well costs are discussed in general, with special emphasis on variations among different geothermal areas in the United States, effects of escalation and inflation over the past few years, and comparisons of geothermal drilling costs with those for oil and gas wells. Cost differences between wells for direct use of geothermal energy and those for electric generation, are also indicated. In addition, a breakdown of total well cost into its components is presented. This provides an understanding of the relative contributions of different operations in drilling and completions. A major portion of the cost in many geothermal wells is from encountered troubles, such as lost circulation, cementing difficulties, and fishing. These trouble costs are considered through both specific examples and statistical treatment of drilling and completions problems. The sensitivities of well costs to variations in several drilling and completion parameters are presented. The mode1 makes it possible to easily vary parameters such as rates of penetration; bit lifetimes; bit rental, or rig costs; delay times; number of cement plugs; etc. are compared.

Advanced Seismic While Drilling System  

SciTech Connect

A breakthrough has been discovered for controlling seismic sources to generate selectable low frequencies. Conventional seismic sources, including sparkers, rotary mechanical, hydraulic, air guns, and explosives, by their very nature produce high-frequencies. This is counter to the need for long signal transmission through rock. The patent pending SeismicPULSER{trademark} methodology has been developed for controlling otherwise high-frequency seismic sources to generate selectable low-frequency peak spectra applicable to many seismic applications. Specifically, we have demonstrated the application of a low-frequency sparker source which can be incorporated into a drill bit for Drill Bit Seismic While Drilling (SWD). To create the methodology of a controllable low-frequency sparker seismic source, it was necessary to learn how to maximize sparker efficiencies to couple to, and transmit through, rock with the study of sparker designs and mechanisms for (a) coupling the sparker-generated gas bubble expansion and contraction to the rock, (b) the effects of fluid properties and dynamics, (c) linear and non-linear acoustics, and (d) imparted force directionality. After extensive seismic modeling, the design of high-efficiency sparkers, laboratory high frequency sparker testing, and field tests were performed at the University of Texas Devine seismic test site. The conclusion of the field test was that extremely high power levels would be required to have the range required for deep, 15,000+ ft, high-temperature, high-pressure (HTHP) wells. Thereafter, more modeling and laboratory testing led to the discovery of a method to control a sparker that could generate low frequencies required for deep wells. The low frequency sparker was successfully tested at the Department of Energy Rocky Mountain Oilfield Test Center (DOE RMOTC) field test site in Casper, Wyoming. An 8-in diameter by 26-ft long SeismicPULSER{trademark} drill string tool was designed and manufactured by TII. An APS Turbine Alternator powered the SeismicPULSER{trademark} to produce two Hz frequency peak signals repeated every 20 seconds. Since the ION Geophysical, Inc. (ION) seismic survey surface recording system was designed to detect a minimum downhole signal of three Hz, successful performance was confirmed with a 5.3 Hz recording with the pumps running. The two Hz signal generated by the sparker was modulated with the 3.3 Hz signal produced by the mud pumps to create an intense 5.3 Hz peak frequency signal. The low frequency sparker source is ultimately capable of generating selectable peak frequencies of 1 to 40 Hz with high-frequency spectra content to 10 kHz. The lower frequencies and, perhaps, low-frequency sweeps, are needed to achieve sufficient range and resolution for realtime imaging in deep (15,000 ft+), high-temperature (150 C) wells for (a) geosteering, (b) accurate seismic hole depth, (c) accurate pore pressure determinations ahead of the bit, (d) near wellbore diagnostics with a downhole receiver and wired drill pipe, and (e) reservoir model verification. Furthermore, the pressure of the sparker bubble will disintegrate rock resulting in an increased overall rates of penetration. Other applications for the SeismicPULSER{trademark} technology are to deploy a low-frequency source for greater range on a wireline for Reverse Vertical Seismic Profiling (RVSP) and Cross-Well Tomography. Commercialization of the technology is being undertaken by first contacting stakeholders to define the value proposition for rig site services utilizing SeismicPULSER{trademark} technologies. Stakeholders include national oil companies, independent oil companies, independents, service companies, and commercial investors. Service companies will introduce a new Drill Bit SWD service for deep HTHP wells. Collaboration will be encouraged between stakeholders in the form of joint industry projects to develop prototype tools and initial field trials. No barriers have been identified for developing, utilizing, and exploiting the low-frequency SeismicPULSER{trademark} source in a

Advanced drilling systems study.  

SciTech Connect

This report documents the results of a study of advanced drilling concepts conducted jointly for the Natural Gas Technology Branch and the Geothermal Division of the U.S. Department of Energy. A number of alternative rock cutting concepts and drilling systems are examined. The systems cover the range from current technology, through ongoing efforts in drilling research, to highly speculative concepts. Cutting mechanisms that induce stress mechanically, hydraulically, and thermally are included. All functions necessary to drill and case a well are considered. Capital and operating costs are estimated and performance requirements, based on comparisons of the costs for alternative systems to conventional drilling technology, are developed. A number of problems common to several alternatives and to current technology are identified and discussed.

Better practices and synthetic fluid improve drilling rates  

SciTech Connect

Improved drilling practices, combined with the use of olefin-based synthetic drilling fluids, have dramatically reduced drilling time and costs in a difficult drilling area in the Gulf of Mexico. In the South Pass area, Marathon Oil Co. and other operators have had wells with long drilling times and high costs. In addition to the two wells with record penetration rates, routine drilling rates have also increased from the use of synthetic mud and careful drilling practices. Through application of these improved drilling practices, 2,000--3,000 ft/day can be drilled routinely. Marathon achieves this goal by applying the experience gained on previous wells, properly training and involving the crews, and using innovative drilling systems. Improved drilling practices and systems are just one part of successful, efficient drilling. Rig site personnel are major contributors to safely and successfully drilling at high penetration rates for extended periods. The on site personnel must act as a team and have the confidence and proper mental attitude about what is going on downhole. The paper describes the drilling history in the South Pass area, the synthetic drilling fluid used, cuttings handling, hole cleaning, drilling practices, bottom hole assemblies, and lost circulation.

Measurement-while-drilling (MWD) development for air drilling  

SciTech Connect

The objective of this program is to tool-harden and make commercially available an existing wireless MWD tool to reliably operate in an air, air-mist, or air-foam environment during Appalachian Basin oil and gas directional drilling operations in conjunction with downhole motors and/or (other) bottom-hole assemblies. The application of this technology is required for drilling high angle (holes) and horizontal well drilling in low-pressure, water sensitive, tight gas formations that require air, air-mist, and foam drilling fluids. The basic approach to accomplishing this objective was to modify GEC`s existing electromagnetic (e-m) ``CABLELESS``{trademark} MWD tool to improve its reliability in air drilling by increasing its tolerance to higher vibration and shock levels (hardening). Another important aim of the program is to provide for continuing availability of the resultant tool for use on DOE-sponsored, and other, air-drilling programs.

Production of Onshore Lower-48 Oil and Gas-model methodology and data description. [PROLOG  

SciTech Connect

This report documents the methodology and data used in the Production of Onshore Lower-48 Oil and Gas (PROLOG) model. The model forecasts annual oil and natural gas production on a regional basis. A linear program is used to select drilling activities for conventional oil and gas on the basis of their economic merit, subject to constraints on available rotary rigs and constraints based on historical drilling patterns. Using an exogenously specified price path, net present values are computed for fixed amounts of drilling activity for oil and gas, and for exploration and development in each of six onshore regions. Forecasts of drilling for enhanced gas recovery (EGR) are exogenously determined, and this drilling is included when considering the constraints on drilling rigs. The report is organized as follows. Chapter 2 is a general overview of the model, describing the major characteristics of the methodology and the logical interaction of the various modules. Chapter 3 specifies the structure of the linear program including the equations for the objective function and the constraints. The details of the methodology used to model exploratory, developmental, and deep gas drilling are presented in Chapters 4-6, respectively. Chapter 7 presents a discussion of the economic evaluation which takes place in each discounted cash flow calculation performed by the model. Cost equations are presented, and various user-specified options as to how to incorporate these costs are discussed. Methodological details and equations used to model finding rates and revisions are given in Chapter 8. Possible areas of future enhancements to the PROLOG model are presented in Chapter 9.

Method of drilling and casing a well  

SciTech Connect

A well drilling rig having a rotary table for driving a drill string rotatively and having jacking mechanism for lowering casing into the well after drilling, with the jacking mechanism including fluid pressure actuated piston and cylinder means which may be left in the rig during drilling and which are positioned low enough in the rig to avoid interference with operation of the rotary table. The jacking mechanism also includes a structure which is adapted to be connected to the piston and cylinder means when the casing or other well pipe is to be lowered and which is actuable upwardly and downwardly and carries one of two pipe gripping units for progressively jacking the pipe downwardly by vertical reciprocation of that structure. The reciprocating structure may take the form of a beam extending between two pistons and actuable thereby, with a second beam being connected to cylinders within which the pistons are contained and being utilized to support the second gripping element. In one form of the invention, the rotary table when in use is supported by this second beam.

Comparative analysis of core drilling and rotary drilling in volcanic terrane  

SciTech Connect

Initially, the goal of this report is to compare and contrast penetration rates of rotary-mud drilling and core drilling in young volcanic terranes. It is widely recognized that areas containing an abundance of recent volcanic rocks are excellent targets for geothermal resources. Exploration programs depend heavily upon reliable subsurface information, because surface geophysical methods may be ineffective, inconclusive, or both. Past exploration drilling programs have mainly relied upon rotary-mud rigs for virtually all drilling activity. Core-drilling became popular several years ago, because it could deal effectively with two major problems encountered in young volcanic terranes: very hard, abrasive rock and extreme difficulty in controlling loss of circulation. In addition to overcoming these difficulties, core-drilling produced subsurface samples (core) that defined lithostratigraphy, structure and fractures far better than drill-chips. It seemed that the only negative aspect of core drilling was cost. The cost-per-foot may be two to three times higher than an ''initial quote'' for rotary drilling. In addition, penetration rates for comparable rock-types are often much lower for coring operations. This report also seeks to identify the extent of wireline core drilling (core-drilling using wireline retrieval) as a geothermal exploration tool. 25 refs., 21 figs., 13 tabs.

SMALLER FOOTPRINT DRILLING SYSTEM FOR DEEP AND HARD ROCK ENVIRONMENTS; FEASIBILITY OF ULTRA-HIGH SPEED DIAMOND DRILLING  

SciTech Connect

The two phase program addresses long-term developments in deep well and hard rock drilling. TerraTek believes that significant improvements in drilling deep hard rock will be obtained by applying ultra-high (greater than 10,000 rpm) rotational speeds. The work includes a feasibility of concept research effort aimed at development and test results that will ultimately result in the ability to reliably drill ''faster and deeper'' possibly with rigs having a smaller footprint to be more mobile. The principle focus is on demonstration testing of diamond bits rotating at speeds in excess of 10,000 rpm to achieve high rate of penetration rock cutting with substantially lower inputs of energy and loads. The project draws on TerraTek results submitted to NASA's ''Drilling on Mars'' program. The objective of that program was to demonstrate miniaturization of a robust and mobile drilling system that expends small amounts of energy. TerraTek successfully tested ultrahigh speed ({approx}40,000 rpm) small kerf diamond coring. Adaptation to the oilfield will require innovative bit designs for full hole drilling or continuous coring and the eventual development of downhole ultra-high speed drives. For domestic operations involving hard rock and deep oil and gas plays, improvements in penetration rates is an opportunity to reduce well costs and make viable certain field developments. An estimate of North American hard rock drilling costs is in excess of $1,200 MM. Thus potential savings of $200 MM to $600 MM are possible if drilling rates are doubled [assuming bit life is reasonable]. The net result for operators is improved profit margin as well as an improved position on reserves. The significance of the ''ultra-high rotary speed drilling system'' is the ability to drill into rock at very low weights on bit and possibly lower energy levels. The drilling and coring industry today does not practice this technology. The highest rotary speed systems in oil field and mining drilling and coring today run less than 10,000 rpm--usually well below 5,000 rpm. This document details the progress to date on the program entitled ''SMALLER FOOTPRINT DRILLING SYSTEM FOR DEEP AND HARD ROCK ENVIRONMENTS; FEASIBILITY OF ULTRA-HIGH SPEED DIAMOND DRILLING'' for the period starting June 23, 2003 through September 30, 2004. (1) TerraTek has reviewed applicable literature and documentation and has convened a project kick-off meeting with Industry Advisors in attendance. (2) TerraTek has designed and planned Phase I bench scale experiments. Some difficulties in obtaining ultra-high speed motors for this feasibility work were encountered though they were sourced mid 2004. (3) TerraTek is progressing through Task 3 ''Small-scale cutting performance tests''. Some improvements over early NASA experiments have been identified.

Influence of reservoir heterogeneity on gas resource potential for geologically based infill drilling, Brooks and I-92 reservoirs, Frio Formation, south Texas  

SciTech Connect

Gas resource potential for strategic infill drilling or recompletion in a reservoir can be calculated by subtracting gas volumes derived using the material balance (pressure decline) method from volumes derived using a volumetric method. This resource potential represents remaining gas that is not in communication with existing wells. Frio reservoirs in mature, nonassociated gas plays located downdip from the Vicksburg fault zone are characterized by multiple, vertically stacked sandstones. The Brooks reservoir, in La Gloria field, lies in a fluvial-dominated system that contains dip-elongate channel sandstone belts 1-2 mi wide. Within these belts are six or more vertically stacked channel-fill, point-bar and splay deposits. Depositional environments were interpreted from SP logs. Individual sandstones are separated vertically by thin mudstone layers and pinch out laterally into flood-plain deposits.

Risk analysis of jackup rigs  

Science Journals Connector (OSTI)

Increasing attention has been focussed in the North Sea and elsewhere on the quantification of the risks of working in a hazardous enviroment: the offshore world. The perception of risk with respect to mobile rigs has often been vague and uninformed. This paper attempts to put the risks with respect to jackup rigs into perspective by quantifying them and comparing them to other risks. This paper contains a few risk comparisons with fixed platforms, semi-submersibles, and drillships. Historical casualties are used in an example to show how a change intended to make an operation safer, may result in the opposite effect. Examining risks from losses due to environmental overload, the conclusion is reached that jackups are very safe structures: there appears to be no jackup, in the timeframe examined, that has been lost because of a deficiency in the calculation methods currently in use by knowledgeable experts.

Deep gas plays are persuading companies like Getty and Mesa petroleum to invest in lease acquisitions  

SciTech Connect

Much of the big money being spent in the Permian Basin may be going to elaborate tertiary projects for improved oil recovery, but the deep natural gas reserves in the Delaware Basin continue to draw the big drilling and leasing dollars. According to the petroleum information's Rotary Report of late April 1981, Texas Railroad Commission district No. 8 in west Texas had 148 rigs running. Of those, 60 were in a 4-county area of Loving, Pecos, Ward, and Reeves Counties. Thirty-four of those rigs in that area were drilling to objectives below 15,000 ft. In the March University Lands Lease Auction, high dollars were directed to portions of west Texas that include the Delaware Basin.

Deep Drilling Basic Research: Volume 4 - System Description. Final Report, November 1988--August 1990  

SciTech Connect

The first section of this Volume will discuss the ''Conventional Drilling System''. Today's complex arrangement of numerous interacting systems has slowly evolved from the very simple cable tool rigs used in the late 1800s. Improvements to the conventional drilling rig have varied in size and impact over the years, but the majority of them have been evolutionary modifications. Each individual change or improvement of this type does not have significant impact on drilling efficiency and economics. However, the change is almost certain to succeed, and over time--as the number of evolutionary changes to the system begin to add up--improvements in efficiency and economics can be seen. Some modifications, defined and described in this Volume as Advanced Modifications, have more than just an evolutionary effect on the conventional drilling system. Although the distinction is subtle, there are several examples of incorporated advancements that have had significantly more impact on drilling procedures than would a truly evolutionary improvement. An example of an advanced modification occurred in the late 1970s with the introduction of Polycrystalline Diamond Compact (PDC) drill bits. PDC bits resulted in a fundamental advancement in drilling procedures that could not have been accomplished by an evolutionary improvement in materials metallurgy, for example. The last drilling techniques discussed in this Volume are the ''Novel Drilling Systems''. The extent to which some of these systems have been developed varies from actually being tested in the field, to being no more than a theoretical concept. However, they all have one thing in common--their methods of rock destruction are fundamentally different from conventional drilling techniques. When a novel drilling system is introduced, it is a revolutionary modification of accepted drilling procedures and will completely replace current techniques. The most prominent example of a revolutionary modification in recent history was the complete displacement of cable tool rigs by rotary drilling rigs in the late 1920s.

Drilling Optimization Utilizing Surface Instrumentaton for Downhole Event Recognition  

SciTech Connect

This DOE project was undertaken to develop and test an instrumented data-acquisition sub that is mounted in a drill string below the top drive and used to detect downhole events. Data recorded at the surface during drilling operations would then be processed and presented to the driller to discern undesirable drilling conditions and help optimize drilling rates and maximize the life of components in the BHA. This instrumented sub was originally conceived and developed solely as a single-point collection center for rig data that would be used in a number of Noble's products. The sub was designed to collect hook load, rotary torque, rotary speed, rotary position, drill pipe pressure, mud temperature, triaxial vibration, and triaxial magnetometer data. The original design and fabrication was by Sandia National Labs under Noble's direction, which was then tested with Sandia's diagnostics-while-drilling downhole package. After initial results were analyzed, the team surmised that important information describing performance and condition of the bottom-hole assembly (BHA) was embedded in the data recorded by the instrumented sub, and began investigating the potential of using surface measurements from the sub to highlight problems occurring downhole before they could be discerned by the driller. Later, a proposal was submitted to DOE for funding to more broadly investigate use of the system for detecting downhole problems while drilling. Soon after DOE awarded this contract, the Noble team responsible for the previous developments was disbanded and their work terminated (due to factors unrelated to the sub development). This change halted the complementary work that Noble had planned to conduct during the DOE project, and necessitated that all the development work be completed by the DOE project. More effort was expended on the project to develop a field-ready prototype than was originally foreseen. The sub's design had to be significantly modified during the project based on results of field tests. The original slip ring for communication was replaced with a radio link, which makes the sub easier to move to different rigs and simplifies the set-up process. In addition, the sub's previous design would prevent it being used on oil and gas rigs due to potential explosion hazard. The sub was redesigned so that during operation all electrical components on the sub are under a blanket of nitrogen. A pressure switch is used so that, should a leak develop, the sub will shut itself down until any problems are repaired. A total of four series of field tests were conducted. The first (mentioned above) was part of the original Noble-sponsored program and in conjunction with Sandia's diagnostics-while-drilling system. Although these tests highlighted important problems, they showed significant promise for the concept, and the sub was returned to Sandia for early repairs and modifications. After the DOE project took possession of the sub, it was tested three more times in the field. The first two DOE tests had the same objective, which was to establish that the sub could function correctly on the rig and deliver usable data, and to develop procedures for setting up and operating the sub and support computer on a rig. During the first test most of the time was spent troubleshooting the sub. Several significant problems were revealed, demonstrating that the current design was not robust enough to survive typical oil field operations. The sub was then redesigned to increase its robustness and allow it to run safely in areas where explosive gases might be present. Once these changes were implemented, the sub was sent to a second shake-down field test. The new design was found to be greatly improved. The sub operated throughout the test, and quality of the data was significantly higher. Near the end of this project, a final field test was conducted with the objective of creating (or simulating) specific problem conditions and recording data to determine if signatures could be recorded and identified that, after analysis, might signify particula

Big-hole drilling - the state of the art  

SciTech Connect

The art of big-hole drilling has been in a continual state of evolution at the Nevada Test Site since the start of underground testing in 1961. Emplacement holes for nuclear devices are still being drilled by the rotary-drilling process, but almost all the hardware and systems have undergone many changes during the intervening years. The current design of bits, cutters, and other big-hole-drilling hardware results from contributions of manufacturers and Test Site personnel. The dual-string, air-lift, reverse-circulation system was developed at the Test Site. Necessity was really the Mother of this invention, but this circulation system is worthy of consideration under almost any condition. Drill rigs for big-hole drilling are usually adaptations of large oil-well drill rigs with minor modifications required to handle the big bits and drilling assemblies. Steel remains the favorite shaft lining material, but a lot of thought is being given to concrete linings, especially precast concrete.

Selectively fired, tubing-conveyed perforating guns save rig time  

SciTech Connect

Selective firing of tubing-conveyed perforating (TCP) guns during drill stem tests (DSTs) added flexibility and saved costs for Marathon Oil Co. As an example, in the Garland field in Wyoming, the guns allowed perforating multiple zones in one trip. This saved 1 1/2--2 days/well in rig time and $25,000--30,000/well in electric wire line and DST tool charges. For international offshore operations, savings of $200,000/well appear possible. Savings result not only from perforating multiple zones, but also from arbitrarily setting firing patterns with or without zone isolation. The paper describes the testing of equipment, the design of the guns, firing heads, crossover assembly, pressure isolation sub, control line, and select-fire sub, and applications for the guns.

HYDRATE CORE DRILLING TESTS  

SciTech Connect

The ''Methane Hydrate Production from Alaskan Permafrost'' project is a three-year endeavor being conducted by Maurer Technology Inc. (MTI), Noble, and Anadarko Petroleum, in partnership with the U.S. DOE National Energy Technology Laboratory (NETL). The project's goal is to build on previous and ongoing R&D in the area of onshore hydrate deposition. The project team plans to design and implement a program to safely and economically drill, core and produce gas from arctic hydrates. The current work scope includes drilling and coring one well on Anadarko leases in FY 2003 during the winter drilling season. A specially built on-site core analysis laboratory will be used to determine some of the physical characteristics of the hydrates and surrounding rock. Prior to going to the field, the project team designed and conducted a controlled series of coring tests for simulating coring of hydrate formations. A variety of equipment and procedures were tested and modified to develop a practical solution for this special application. This Topical Report summarizes these coring tests. A special facility was designed and installed at MTI's Drilling Research Center (DRC) in Houston and used to conduct coring tests. Equipment and procedures were tested by cutting cores from frozen mixtures of sand and water supported by casing and designed to simulate hydrate formations. Tests were conducted with chilled drilling fluids. Tests showed that frozen core can be washed out and reduced in size by the action of the drilling fluid. Washing of the core by the drilling fluid caused a reduction in core diameter, making core recovery very difficult (if not impossible). One successful solution was to drill the last 6 inches of core dry (without fluid circulation). These tests demonstrated that it will be difficult to capture core when drilling in permafrost or hydrates without implementing certain safeguards. Among the coring tests was a simulated hydrate formation comprised of coarse, large-grain sand in ice. Results with this core showed that the viscosity of the drilling fluid must also be carefully controlled. When coarse sand was being cored, the core barrel became stuck because the drilling fluid was not viscous enough to completely remove the large grains of sand. These tests were very valuable to the project by showing the difficulties in coring permafrost or hydrates in a laboratory environment (as opposed to a field environment where drilling costs are much higher and the potential loss of equipment greater). Among the conclusions reached from these simulated hydrate coring tests are the following: Frozen hydrate core samples can be recovered successfully; A spring-finger core catcher works best for catching hydrate cores; Drilling fluid can erode the core and reduces its diameter, making it more difficult to capture the core; Mud must be designed with proper viscosity to lift larger cuttings; and The bottom 6 inches of core may need to be drilled dry to capture the core successfully.

Techniques Techniques Jump to: navigation, search Dictionary.png Drilling Techniques There are a variety of drilling techniques which can be used to sink a borehole into the ground. Each has its advantages and disadvantages, in terms of the depth to which it can drill, the type of sample returned, the costs involved and penetration rates achieved. There are two basic types of drills: drills which produce rock chips, and drills which produce core samples.[1] View on Wikipedia Wikipedia Definition Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

Calculating limits for torsion and tensile loads on drill pipe  

SciTech Connect

Drill pipe used for drilling horizontal and extended reach holes experiences much higher torsional and tensile loads than normally seen while drilling vertical holes. This is particularly true for rigs with top drives vs. rigs with rotary tables. When pipe is rotated while pulling out of the hole, which is commonly done on top drive rigs, the drill pipe can experience high tensile and torsional loading simultaneously. These conditions increase the probability of overload on tool joints and require that the drill pipe and tool joint selection process include consideration of combined loading. Calculating the required drill pipe strength for vertical holes is straightforward and spelled out in Section 5 of API RP7G. In vertical hole applications, pipe is almost always selected for its tensile capacity and the torsional strength of the pipe generally does not require special consideration. In Section 4 of API Sec 7, API recommends that the tool joints have a torsional strength of 80% of the pipe`s torsional strength; this is usually adequate. The torsional strength and tensile strength of commonly used drill pipe and tool joint combinations are tabulated in Tables 2 through 10 of API RP7G. Appendix A.8.3 in API RP7G shows a method for plotting a graphical representation of the combined torsional and tensile operational limits of tool joints. How to calculate the limits of the drill pipe tube is shown in Appendix A.9.2. This paper defines terms and limits, and discusses building and using a diagram to determine safe loads.

Slimhole Drilling, Logging, and Completion Technology - An Update  

SciTech Connect

Using slim holes (diameter < 15 cm) for geothermal exploration and small-scale power production can produce significant cost savings compared to conventional rotary-drilling methods. In addition, data obtained from slim holes can be used to lower the risks and costs associated with the drilling and completion of large-diameter geothermal wells. As a prime contractor to the U.S. Department of Energy (DOE), Sandia National Laboratories has worked with industry since 1992 to develop and promote drilling, testing, and logging technology for slim holes. This paper describes the current status of work done both in-house and contracted to industry. It focuses on drilling technology, case histories of slimhole drilling projects, data collection and rig instrumentation, and high-temperature logging tools.

Chemical Speciation of Chromium in Drilling Muds  

SciTech Connect

Drilling muds are made of bentonite and other clays, and/or polymers, mixed with water to the desired viscosity. Without the drilling muds, corporations could not drill for oil and gas and we would have hardly any of the fuels and lubricants considered essential for modern industrial civilization. There are hundreds of drilling muds used and some kinds of drilling muds contain chromium. The chemical states of chromium in muds have been studied carefully due to concerns about the environmental influence. However it is difficult to determine the chemical state of chromium in drilling muds directly by conventional analytical methods. We have studied the chemical form of chromium in drilling muds by using a laboratory XAFS system and a synchrotron facility.

The Natural Gas Industry and Markets in 2003  

Gasoline and Diesel Fuel Update (EIA)

3 3 Overview The natural gas industry in 2003 experienced sustained high prices, supported at least in part by pressure on supplies as gas in storage was rebuilt from historic lows in the early part of the year. The national annual average natural gas wellhead price was $4.88 per thousand cubic feet (Mcf), which is the highest wellhead price (based on 2003 constant dollars) in the Energy Information Administration's historical data series dating to 1930. U.S. marketed production was virtually unchanged compared with the previous year at 19.9 trillion cubic feet (Tcf), despite the high prices and an increased number of drilling rigs employed in the commercial development of gas deposits. Imports of liquefied natural gas (LNG) mitigated supply declines, reaching a record

Core and sediment physical property correlation of the second Ulleung Basin Gas Hydrate Drilling Expedition (UBGH2) results in the East Sea (Japan Sea)  

Science Journals Connector (OSTI)

Abstract We analyzed the data consist of core digital images and X-rays, core-logs, LWD (logging-while-drilling), and sediment grain-size from the second Ulleung Basin Gas Hydrate Expedition (UBGH2) in the East Sea. Core digital images and X-rays were spliced as a complete composite core in meters below seafloor (mbsf) for five sites; UBGH2-1_1 (Hole D), 2_1 (B), 2_2 (B), 2-6 (B) and 2-10 (C–D), and were correlated with the core-log and LWD measurements showing that possible gas hydrate bearing layers are between the depths of about 60–180 mbsf at these sites. Bulk densities generally increase with depth from 1.3 to 2.0 g/cm3 in LWD data, and from 1.1 to 1.8 g/cm3 onboard which measured lower than in-situ. Gas hydrate bearing sediments respond with an increase of LWD densities (1.4–1.6 g/cm3) and a decrease in core-logs (1.1–1.4 g/cm3). P-wave velocity values of LWD increase (1400 to 1700 m/s) with depth for non-reservoirs, and are high (1500 and 2000 m/s) within the gas hydrate bearing intervals depending on the hydrate saturations.Resistivity values logged onboard range from less than 1.0 to over 10.0 ?-m, while LWD records are around 1.0 ?-m and between 5.0 and 30.0 ?-m in background sediments and possible gas hydrate reservoirs, respectively. High resistivity values were observed (5.0–30.0 ?-m) within coarse-grained turbidites (mean grain-size between 2.9 and 5.1 ?; laminated sandy mud or muddy sands). Medium resistivities were observed (5.0 ?-m) within the silt-dominant hemi-pelagic and turbiditic sediments (5.1–7.4 ?; crudely laminated, bioturbated, homogeneous sand, and disintegrated sand and sandy mud facies) bearing pore-filling gas hydrates, or disseminated gas hydrates either formed in pores or small fractures of fine-grained sediments. Core-log measurements are highly fluctuating and sensitive but mostly lower (e.g., density and resistivity) than LWD records.

February 20, 2004 February 20, 2004 New Projects to Investigate "Smart Drilling" Options Promise Lower Cost, More Reliable Gas Drilling Two additional projects have been selected under a Department of Energy solicitation designed to advance performance when drilling for natural gas. The projects are a key component of the Department's gas exploration and production research program, and support the President's National Energy Policy, which calls for boosting domestic production of natural gas to ensure an adequate future supply at reasonable prices. With shallow and conventional natural gas resources in the United States being depleted, drillers must reach for gas miles below the earth's surface, where temperatures run up to 450 EF and pressures are hundreds of times greater than atmospheric pressure. "Smart drilling" options can increase productivity, improve drilling safety, and lower costs when drilling for these hard-to-reach deep gas supplies.

Rotating mousehole improves top drive/conventional drilling  

SciTech Connect

Top drive speed and efficiency are limited and have not reached full potential because of operation ``bottlenecks`` during makeup or breakout of triple pipe stands and bottomhole assembly (BHA) change out. Operators and contractors analyzed tools to overcome these limitations and found a potential solution from International Tool Co., a supplier of kelly spinners, in a tool that has improved make/break efficiency and rig floor safety. The Phantom Mouse rotating mousehole assembly was developed to improve drilling efficiency on top-drive-equipped rigs. This new device tightens connections so pipe stands can be set back in derricks. Using the system, crews can quickly and efficiently make up and set back DP stands while drilling ahead with top drives. It can also be used to break out and lay down excess DP from the derrick.

Improve drilling efficiency with two nozzles and more weight-on-bit  

SciTech Connect

Field tests evaluated the performance of three-cone insert bits using only two nozzles sized from pressure measurements made at the rig to give maximum hydraulic impact. The tests were conducted on two rigs in California and three in Texas. Test techniques entailed finding a suitable formation that required two identical bits to drill through. The first bit was operated with three nozzles while the subsequent bit was operated with two nozzles. During the test the drilling parameters (such as weight-on-bit, rotary speed, nozzle flow area, pump pressure, circulation rate, and mud weight) were kept as constant as possible. Drilling rates of the two bits were then compared and analyzed with the aid of mud-logs, electric-logs, and drilling recorder information. The depth and the relative position of the formation were also carefully compared with offset well bit records.

Investigation of the feasibility of deep microborehole drilling  

SciTech Connect

Recent advances in sensor technology, microelectronics, and telemetry technology make it feasible to produce miniature wellbore logging tools and instrumentation. Microboreholes are proposed for subterranean telemetry installations, exploration, reservoir definition, and reservoir monitoring this assumes that very small diameter bores can be produced for significantly lower cost using very small rigs. A microborehole production concept based on small diameter hydraulic or pneumatic powered mechanical drilling, assemblies deployed on coiled tubing is introduced. The concept is evaluated using, basic mechanics and hydraulics, published theories on rock drilling, and commercial simulations. Small commercial drill bits and hydraulic motors were selected for laboratory scale demonstrations. The feasibility of drilling deep, directional, one to two-inch diameter microboreholes has not been challenged by the results to date. Shallow field testing of prototype systems is needed to continue the feasibility investigation.

A study of the pore-blocking ability and formation damage characteristics of oil-based colloidal gas aphron drilling fluids  

Science Journals Connector (OSTI)

Abstract The colloidal gas aphron (CGA) based drilling fluids are designed to minimize filtration loss by blocking the pores of the rock with microbubbles. Aphrons behave like a flexible bridging material and form an internal seal in a pore-structure, which can later be removed easily when the well is open for production. A non-aqueous CGA fluid was formulated by mixing 0.4% W/W oil soluble surfactant (sorbitan fatty acid ester ) and a 1.5% W/W linear polymer (styrene–ethylene–propylene) with mineral oil at a very high shear rate. The CGA fluid was used in a series of core flooding experiments to see the effects of the fluid injection rate, the type of saturating fluid, and wettability of the porous media on the pressure drop across the porous media and return permeability. Effective pore blocking ability of CGA fluid was confirmed by ever increasing resistance to the injection of CGA fluid through the porous media (i.e., continuous increase of pressure drop across the porous media). Results confirmed that microbubble buildup has occurred in the porous media, which limits the fluid invasion. The permeability alteration, measured as an indication of the formation damage due to CGA fluid flow, was found to be variable.

Slim hole drilling proven in remote exploration project  

SciTech Connect

This paper reports on a helicopter-supported slim hole exploration project in a remote tropical forest which cost 15% less than a conventional drilling operation. The potential savings after improvements in rig equipment, bits, and drilling and coring methods may approach 30%. Because of the small size of the slim hole equipment, the impact on the rain forest was small. The areas cleared for locations and access during the operation were 75% less than that required for similar operations with conventional road-transported rigs. During the second half of 1991, Total Exploration Gabon, a subsidiary of Total Exploration Production, conducted a slim hole drilling project in the Gabonese tropical rain forest in a joint venture with Chevron Corp., Exxon Corp., and Austria's OMV AG. During this helicopter-supported operation, two wells were drilled: one to 2,747 m (9,010 ft) ending with a 3 in. hole and one to 418 m (1,371 ft) ending with a 5-7/8 in. hole. Continuous coring operations recovered 1,868 m (6,127 ft), or 59% of the total length drilled.

Kinetic inhibition of natural gas hydrates in offshore drilling, production, and processing operations. Annual report, January 1--December 31, 1992  

SciTech Connect

Natural gas hydrates are solid crystalline compounds which form when molecules smaller than n-butane contact molecules of water at elevated pressures and reduced temperatures, both above and below the ice point. Because these crystalline compounds plug flow channels, they are undesirable. In this project the authors proposed an alternate approach of controlling hydrate formation by preventing hydrate growth into a sizeable mass which could block a flow channel. The authors call this new technique kinetic inhibition, because while it allows the system to exist in the hydrate domain, it prevents the kinetic agglomeration of small hydrate crystals to the point of pluggage of a flow channel. In order to investigate the kinetic means of inhibiting hydrate formation, they held two consortium meetings, on June 1, 1990 and on August 31, 1990. At subsequent meetings, the authors determined the following four stages of the project, necessary to reach the goal of determining a new hydrate field inhibitor: (1) a rapid screening method was to be determined for testing the hydrate kinetic formation period of many surfactants and polymer candidates (both individually and combined), the present report presents the success of two screening apparatuses: a multi-reactor apparatus which is capable of rapid, high volume screening, and the backup screening method--a viscometer for testing with gas at high pressure; (2) the construction of two high, constant pressure cells were to experimentally confirm the success of the chemicals in the rapid screening apparatus; (3) in the third phase of the work, Exxon volunteered to evaluate the performance of the best chemicals from the previous two stages in their 4 inch I.D. Multiphase flow loop in Houston; (4) in the final phase of the work, the intention was to take the successful kinetic inhibition chemicals from the previous three stages and then test them in the field in gathering lines and wells from member companies.

Innovative technology summary report: Cryogenic drilling  

SciTech Connect

Environmental drilling is used to conduct site investigations and to install monitoring and remediation wells. Employing conventional drilling techniques to conduct environmental investigations in unconsolidated soils can result in borehole collapse and may also lead to cross-contamination of aquifers and soil formations. For investigations in certain geologic conditions, there are currently no viable conventional drilling techniques available. Cryogenic drilling improves upon conventional air rotary drilling by replacing ambient air with cold nitrogen (either liquid or gas) as the circulating medium. The cold nitrogen gas stream freezes moisture in the ground surrounding the hole. The frozen zone prevents the collapse of the hole and prevents the movement of groundwater or contaminants through and along the hole. The technology, its performance, uses, cost, and regulatory issues are discussed.

Coiled tubing drilling with supercritical carbon dioxide  

DOE Patents (OSTI)

A method for increasing the efficiency of drilling operations by using a drilling fluid material that exists as supercritical fluid or a dense gas at temperature and pressure conditions existing at a drill site. The material can be used to reduce mechanical drilling forces, to remove cuttings, or to jet erode a substrate. In one embodiment, carbon dioxide (CO.sub.2) is used as the material for drilling within wells in the earth, where the normal temperature and pressure conditions cause CO.sub.2 to exist as a supercritical fluid. Supercritical carbon dioxide (SC--CO.sub.2) is preferably used with coiled tube (CT) drilling equipment. The very low viscosity SC--CO.sub.2 provides efficient cooling of the drill head, and efficient cuttings removal. Further, the diffusivity of SC--CO.sub.2 within the pores of petroleum formations is significantly higher than that of water, making jet erosion using SC--CO.sub.2 much more effective than water jet erosion. SC--CO.sub.2 jets can be used to assist mechanical drilling, for erosion drilling, or for scale removal. A choke manifold at the well head or mud cap drilling equipment can be used to control the pressure within the borehole, to ensure that the temperature and pressure conditions necessary for CO.sub.2 to exist as either a supercritical fluid or a dense gas occur at the drill site. Spent CO.sub.2 can be vented to the atmosphere, collected for reuse, or directed into the formation to aid in the recovery of petroleum.

Offshore oil and gas: global resource knowledge and technological change  

Science Journals Connector (OSTI)

It is argued that the contribution of technological change to the offshore oil and gas industry's progress is under-researched. As a prelude this theme, the changing geography of known offshore oil and gas resources is reviewed. Significant, and largely technologically dependent, developments are identified in terms of the industry's global spread, its extension into deep and ultradeep waters and its ability to enhance output from well-established oil and gas provinces. Three sections (on the evolution of exploration and production rigs, drilling techniques and the application of IT to improve resource knowledge and access) then examine the relationships between technological change and the offshore industry's progress. It is concluded that new technologies improve knowledge of, and access to, resources via four distinctive routes, but that the full impact of R & D is frequently related to the inter-dependence of technologies. Opportunities for further research are identified.

An advanced geothermal drilling system: Component options and limitations  

SciTech Connect

The historical developments of drilling technology for geothermal resources have followed traditional incremental trends. The local expertise and rigs were adapted from existing drill rigs used for mining, civil, and water well projects. In areas with hydrocarbon resources, petroleum drilling hardware has been adapted; and in other countries, these units were imported as depth requirements increased and more robust derricks and downhole tools were needed. This ad hoc approach has provided adequate exploration and production wells. In contrast to the incremental improvements in petroleum rotary drilling system components this paper reviews a new, purpose-developed system that would solve the known major problems by design. Performance goals of 4 km (12,000 ft.) depth, 400 C, (750 F) and penetration rates greater than 8 m/h (25 ft/h) were selected. This advanced system was reviewed extensively and estimates of perhaps 30 to 60% cost savings were projected, depending on the assumed effectiveness and performance improvements provided. This paper continues the design and feasibility study and presents some of the component and sub-system details developed thus far.

State-of-the-art in coalbed methane drilling fluids  

SciTech Connect

The production of methane from wet coalbeds is often associated with the production of significant amounts of water. While producing water is necessary to desorb the methane from the coal, the damage from the drilling fluids used is difficult to assess, because the gas production follows weeks to months after the well is drilled. Commonly asked questions include the following: What are the important parameters for drilling an organic reservoir rock that is both the source and the trap for the methane? Has the drilling fluid affected the gas production? Are the cleats plugged? Does the 'filtercake' have an impact on the flow of water and gas? Are stimulation techniques compatible with the drilling fluids used? This paper describes the development of a unique drilling fluid to drill coalbed methane wells with a special emphasis on horizontal applications. The fluid design incorporates products to match the delicate surface chemistry on the coal, a matting system to provide both borehole stability and minimize fluid losses to the cleats, and a breaker method of removing the matting system once drilling is completed. This paper also discusses how coal geology impacts drilling planning, drilling practices, the choice of drilling fluid, and completion/stimulation techniques for Upper Cretaceous Mannville-type coals drilled within the Western Canadian Sedimentary Basin. A focus on horizontal coalbed methane (CBM) wells is presented. Field results from three horizontal wells are discussed, two of which were drilled with the new drilling fluid system. The wells demonstrated exceptional stability in coal for lengths to 1000 m, controlled drilling rates and ease of running slotted liners. Methods for, and results of, placing the breaker in the horizontal wells are covered in depth.

Improved practices, synthetic mud drive record 24-hr drilling  

SciTech Connect

Revised and improved drilling practices resulted in increased rate of penetration (ROP), improved hole cleaning, decreased circulating time, fewer instances of stuck pipe and reduced total drilling days. Rig equipment modifications and optimized techniques, combined with olefin-based synthetic fluid, produced significant efficiency improvements and cost reductions. Total-project strategy allows best technologies to be used, even if they are not low bid. In the Gulf of Mexico, a total-project concept helped Marathon drill back-to-back record 24-hr footages. Methods and philosophy described in this article allow drillers to choose optimum technologies, tools, materials and service performance for achieving optimum or lowest cost per foot rather than always using low bid.

MIMO Control during Oil Well Drilling  

Science Journals Connector (OSTI)

Abstract A drilling system consists of a rotating drill string, which is placed into the well. The drill fluid is pumped through the drill string and exits through the choke valve. An important scope of the drill fluid is to maintain a certain pressure gradient along the length of the well. Well construction is a complex job in which annular pressures must be kept inside the operational window (limited by fracture and pore pressure). Monitoring bottom hole pressure to avoid fluctuations out of operational window limits is an extremely important job, in order to guarantee safe conditions during drilling. Under a conventional oil well drilling task, the pore pressure (minimum limit) and the fracture pressure (maximum limit) define mud density range and pressure operational window. During oil well drilling, several disturbances affect bottom hole pressure; for example, as the length of the well increases, the bottom hole pressure varies for growing hydrostatic pressure levels. In addition, the pipe connection procedure, performed at equal time intervals, stopping the drill rotation and mud injection, mounting a new pipe segment, restarting the drill fluid pump and rotation, causes severe fluctuations in well fluids flow, changing well pressure. Permeability and porous reservoir pressure governs native reservoir fluid well influx, affecting flow patterns inside the well and well pressure. In this work, a non linear mathematical model (gas-liquid-solid), representing an oil well drilling system, was developed, based on mass and momentum balances. Besides, for implementing classic control (PI), alternative control schemes were analyzed using mud pump flow rate, choke opening index and weight on bit as manipulated variables in order to control annulus bottomhole pressure and rate of penetration. Classic controller tuning was performed for servo and regulatory control studies, under MIMO frameworks.

HydroPulse Drilling  

SciTech Connect

Tempress HydroPulse{trademark} tool increases overbalanced drilling rates by generating intense suction pulses at the drill bit. This report describes the operation of the tool; results of pressure drilling tests, wear tests and downhole drilling tests; and the business case for field applications. The HydroPulse{trademark} tool is designed to operate on weighted drilling mud at conventional flow rates and pressures. Pressure drilling tests confirm that the HydroPulse{trademark} tool provides 33% to 200% increased rate of penetration. Field tests demonstrated conventional rotary and mud motor drilling operations. The tool has been operated continuous for 50 hours on weighted mud in a wear test stand. This level of reliability is the threshold for commercial application. A seismic-while-drilling version of the tool was also developed and tested. This tool was used to demonstrate reverse vertical seismic profiling while drilling an inclined test well with a PDC bit. The primary applications for the HydroPulse{trademark} tool are deep onshore and offshore drilling where rate of penetration drives costs. The application of the seismic tool is vertical seismic profiling-while-drilling and look-ahead seismic imaging while drilling.

Research and Application of Auger-air Drilling and Sieve Tube Borehole Protection in Soft Outburst-prone Coal Seams  

Science Journals Connector (OSTI)

Abstract Hole accidents during drilling and borehole collapse during extracting are bottlenecks restricting gas drainage efficiency in soft outburst-prone coal seams in China. The auger-air combined drilling technique and sieve tube mounting method are an alternative solution to these technology bottlenecks. The auger-air drilling technique combines the advantages of “dry style” auger drilling and air drilling. Specially designed blade in drill rod can stir up large particles of coal so that large particles can be brought to ground smoothly using compressed air and is efficient to prevent borehole accidents. After drilling is completed, the sieve tube is tripped in through the inner hole of drilling pipes, and then lifting up drilling pipes, the tube sieve will provide a complete tunnel for gas extraction. Field application proves that with proper drilling parameter selection and appropriate tube install control, it is more promising to double drilling depth and raise gas drainage efficiency.

Counter-Rotating Tandem Motor Drilling System  

SciTech Connect

Gas Technology Institute (GTI), in partnership with Dennis Tool Company (DTC), has worked to develop an advanced drill bit system to be used with microhole drilling assemblies. One of the main objectives of this project was to utilize new and existing coiled tubing and slimhole drilling technologies to develop Microhole Technology (MHT) so as to make significant reductions in the cost of E&P down to 5000 feet in wellbores as small as 3.5 inches in diameter. This new technology was developed to work toward the DOE's goal of enabling domestic shallow oil and gas wells to be drilled inexpensively compared to wells drilled utilizing conventional drilling practices. Overall drilling costs can be lowered by drilling a well as quickly as possible. For this reason, a high drilling rate of penetration is always desired. In general, high drilling rates of penetration (ROP) can be achieved by increasing the weight on bit and increasing the rotary speed of the bit. As the weight on bit is increased, the cutting inserts penetrate deeper into the rock, resulting in a deeper depth of cut. As the depth of cut increases, the amount of torque required to turn the bit also increases. The Counter-Rotating Tandem Motor Drilling System (CRTMDS) was planned to achieve high rate of penetration (ROP) resulting in the reduction of the drilling cost. The system includes two counter-rotating cutter systems to reduce or eliminate the reactive torque the drillpipe or coiled tubing must resist. This would allow the application of maximum weight-on-bit and rotational velocities that a coiled tubing drilling unit is capable of delivering. Several variations of the CRTDMS were designed, manufactured and tested. The original tests failed leading to design modifications. Two versions of the modified system were tested and showed that the concept is both positive and practical; however, the tests showed that for the system to be robust and durable, borehole diameter should be substantially larger than that of slim holes. As a result, the research team decided to complete the project, document the tested designs and seek further support for the concept outside of the DOE.

A new type of whole oil-based drilling fluid  

Science Journals Connector (OSTI)

Abstract To meet the demand of ultra-deep well drilling and shale gas well drilling, organic clay and a oil-based filtrate reducer were developed and a whole oil-based drilling fluid formula was optimized. The performance of organic clay, oil-based filtrate reducer and the whole oil-based drilling fluid were evaluated in laboratory, and the whole oil-based drilling fluid was applied in drilling process for further test of its performance. Long carbon chain quaternary ammonium salt was used as modifying agents when synthesizing organobentonites. Oil-based filtrate reducer was synthesized with monomers of lignite and amine class. The laboratory tests show that the organic clay can effectively increase the viscosity of oil-based drilling fluid and the oil-based filtrate reducer can reduce the fluid loss. Their performances were better than additives of the same kind at home and abroad. The organic clay and oil-based filtrate reducer had great compatibility with the other additives in oil-based drilling fluid. Based on the optimal additives addition amount tests, the whole oil-based drilling fluid formula was determined and the test results show that the performances of the whole oil-based drilling fluids with various densities were great. The laboratory tests show that the oil-based drilling fluid developed was high temperature resistant, even at 200 °C, as density varies from 0.90 to 2.0 g/cm3, it still held good performance with only a little fluid loss, good inhibition, great anti-pollution, and good reservoir protection performance. Field application result shows that the performance of the oil-based drilling fluid is stable with great ability to maintain wellbore stability and lower density than the water-based drilling fluid; drilling bits can be used much longer and the average penetration rate is increased; the oil-based drilling fluid can satisfy the drilling requirements.

Comparison of revegetation of a gas pipeline right-of-way in two forested wetland crossings involving conventional methods of pipeline installation and horizontal drilling, Nassau County, Florida  

SciTech Connect

One year after pipeline installation, vegetation in the right-of-way (ROW) was inventoried at two stream floodplain crossings in Nassau County, Florida. Both sites were forested wetlands composed of Acer rubrum, Fraxinus caroliniana, Liquidamber styraciflua, Nyssa ogecho, Quercus laurifolia, and Taxodium distichum, together with other wetland trees. Pipeline installation across the Brandy Branch floodplain was by conventional ditching and backfill methods. Installation across the Deep Creek floodplain was by horizontal drilling after clearcutting the ROW. The latter method left tree stumps, understory vegetation, and soil layers intact, except for disruptions caused by logging. According to the inventory, vegetation at the drilled site was more diverse (nearly twice as many species occurring in the ROW as at the trenched site) and more robust (no unvegetated exposed soil compared to 15% at the trenched site). Differences between the ROW vegetation at the two sites can be attributed to both site differences and installation technologies used.

Method of deep drilling  

DOE Patents (OSTI)

Deep drilling is facilitated by the following steps practiced separately or in any combination: (1) Periodically and sequentially fracturing zones adjacent the bottom of the bore hole with a thixotropic fastsetting fluid that is accepted into the fracture to overstress the zone, such fracturing and injection being periodic as a function of the progression of the drill. (2) Casing the bore hole with ductile, pre-annealed casing sections, each of which is run down through the previously set casing and swaged in situ to a diameter large enough to allow the next section to run down through it. (3) Drilling the bore hole using a drill string of a low density alloy and a high density drilling mud so that the drill string is partially floated.

Development and Demonstration of Mobile, Small Footprint Exploration and Development Well System for Arctic Unconventional Gas Resources (ARCGAS)  

SciTech Connect

Traditionally, oil and gas field technology development in Alaska has focused on the high-cost, high-productivity oil and gas fields of the North Slope and Cook Inlet, with little or no attention given to Alaska's numerous shallow, unconventional gas reservoirs (carbonaceous shales, coalbeds, tight gas sands). This is because the high costs associated with utilizing the existing conventional oil and gas infrastructure, combined with the typical remoteness and environmental sensitivity of many of Alaska's unconventional gas plays, renders the cost of exploring for and producing unconventional gas resources prohibitive. To address these operational challenges and promote the development of Alaska's large unconventional gas resource base, new low-cost methods of obtaining critical reservoir parameters prior to drilling and completing more costly production wells are required. Encouragingly, low-cost coring, logging, and in-situ testing technologies have already been developed by the hard rock mining industry in Alaska and worldwide, where an extensive service industry employs highly portable diamond-drilling rigs. From 1998 to 2000, Teck Cominco Alaska employed some of these technologies at their Red Dog Mine site in an effort to quantify a large unconventional gas resource in the vicinity of the mine. However, some of the methods employed were not fully developed and required additional refinement in order to be used in a cost effective manner for rural arctic exploration. In an effort to offset the high cost of developing a new, low-cost exploration methods, the US Department of Energy, National Petroleum Technology Office (DOE-NPTO), partnered with the Nana Regional Corporation and Teck Cominco on a technology development program beginning in 2001. Under this DOE-NPTO project, a team comprised of the NANA Regional Corporation (NANA), Teck Cominco Alaska and Advanced Resources International, Inc. (ARI) have been able to adapt drilling technology developed for the mineral industry for use in the exploration of unconventional gas in rural Alaska. These techniques have included the use of diamond drilling rigs that core small diameter (< 3.0-inch) holes coupled with wireline geophysical logging tools and pressure transient testing units capable of testing in these slimholes.

Drilling continues upward momentum  

SciTech Connect

This paper discusses how the drilling recovery that began during the second half of 1989 is continuing into 1990. On top of this, the Iraqi invasion of Kuwait has caused disarray in oil markets, driving up oil prices, and disrupting access to oil supplies. Potentially, this upheaval could lead to an upward spike in worldwide drilling activity.

Chapter 4 Drilling Engineering  

Science Journals Connector (OSTI)

Publisher Summary Drilling operations are essentially carried out during all stages of the project life cycle (PLC) and in all types of environments. The main objectives of these operations includes: the acquisition of information and the safeguarding of production. Since the expenditure for drilling represents a large fraction of the total project's capital expenditure, an understanding of the techniques, equipment, and cost of drilling is very significant. This chapter focuses on the drilling activities. The chapter also explores the interactions between the drilling team and the other exploration and production (E&P) functions. Specifically, an initial successful exploration well can establish the presence of a working petroleum system. Following this, the data gathered in the first well is evaluated and the results are documented. The next step includes the appraisal of the accumulation requiring more wells. Finally, if the project is subsequently moved forward, development wells then needs to be engineered.

Noise removal from measurements while drilling an oil well  

Science Journals Connector (OSTI)

Systems to acquire borehole data during the drilling of oil and gas wells make use of measurement while drilling (MWD). One feature of this system is that it is able to do real?time measuring from a borehole; therefore there has been a lot of MWD use on drilling sites in recent years. There are a few types of MWD. Mud pulse?type MWD which uses a drilling circuit fluid is superior to the rest because of its reliability accuracy of data and less disturbance of the drilling schedule. The drilling circuit fluid is raised to a high pressure by a mud pump; borehole data which are recorded by the surface measuring system are contaminated by the pumping noise. Therefore it is necessary to remove the pumping noise to get objective data. This report describes the pumping noise removal system and the method used for the telemetry system from 2000 m depth.

Field testing of new multilateral drilling and completion technology at the Rocky Mountain Oilfield Testing Center  

SciTech Connect

The Rocky Mountain Oilfield Testing Center (RMOTC) has played an important role in bringing new multilateral well technology to the marketplace. Multilateral technology is more complex than most new technologies being brought to the oilfield. It is very difficult to test new designs in the laboratory or conventional test wells. They must be tested downhole in specialized wells to work out design and procedural details. Most of the applications for multilateral technology are in high cost drilling areas, such as offshore or in remote, environmentally sensitive areas. For this reason, opportunities for testing the new technology in the course of routine drilling and completion operations are scarce. Operators are not willing to risk expensive rig time, or losing a wellbore itself, on a test. RMOTC offers a neutral site where the technology can be tested in a relatively low cost environment. There are two drilling rigs and three workover and completion rigs available. Most associated services such as warehouse, roustabouts, backhoe, welders, and mechanics are also available on site, while specialized oilfield services and machine shops are available in nearby Casper. Technologies such as the hollow whipstock, adjustable stabilizer, downhole kickoff assembly, single trip sidetrack tool, stacked multidrain system, rotary steerable systems, and procedures for abandoning an open hole lateral have benefited through the use of RMOTC`s facilities. This paper details the capabilities of the new technologies and the benefits of testing them in a real oilfield environment before taking them to market.

Blast furnace taphole drill  

SciTech Connect

A blast furnace taphole drill has a flaring head with cutting edges at its cutting end formed by intersecting angled faces. A central bore carries cleaning air to the cutting end. To prevent blockage of the cleaning air bore by debris and possible jamming of the drill, the head has deep radial grooves formed at the bottoms of the valley shapes between the cutting edges. The grooves extend radially from the air bore and conduct the air so that it can get behind or under jammed debris. Reduced taphole drilling times can be achieved.

Interdependence of the Electricity Generation System and the Natural Gas System and Implications for Energy Security  

E-Print Network (OSTI)

Approved for public release; distribution is unlimited. Lexington Massachusetts This page intentionally left blank. EXECUTIVE SUMMARY Concern about energy security on domestic Department of Defense installations has led to the possibility of using natural gas-fired electricity generators to provide power in the event of electric grid failures. As natural gas is an increasingly base-load fuel for electricity generation in the United States, the electricity generation system has become increasingly dependent on the operation of the natural gas system. However, as the natural gas system is also partly dependent on electricity for its ability to deliver natural gas from the well-head to the consumer, the question arises of whether, in the event of an electric grid failure, the natural gas would continue to flow. As the natural gas transmission system largely uses natural gas from the pipelines as a source of power, once the gas has been extracted from the ground, the system is less dependent on the electric grid. However, some of the drilling rigs, processing units, and pipeline compressors do depend on electric power, making the vulnerability to the system to a disruption in the national electricity supply network vary depending on the cause, breadth, and geographic location of the disruption. This is due to the large numbers of players in the natural gas production and

Smaller Footprint Drilling System for Deep and Hard Rock Environments; Feasibility of Ultra-High-Speed Diamond Drilling  

SciTech Connect

The two phase program addresses long-term developments in deep well and hard rock drilling. TerraTek believes that significant improvements in drilling deep hard rock will be obtained by applying ultra-high rotational speeds (greater than 10,000 rpm). The work includes a feasibility of concept research effort aimed at development that will ultimately result in the ability to reliably drill 'faster and deeper' possibly with smaller, more mobile rigs. The principle focus is on demonstration testing of diamond bits rotating at speeds in excess of 10,000 rpm to achieve high rate of penetration (ROP) rock cutting with substantially lower inputs of energy and loads. The significance of the 'ultra-high rotary speed drilling system' is the ability to drill into rock at very low weights on bit and possibly lower energy levels. The drilling and coring industry today does not practice this technology. The highest rotary speed systems in oil field and mining drilling and coring today run less than 10,000 rpm - usually well below 5,000 rpm. This document provides the progress through two phases of the program entitled 'Smaller Footprint Drilling System for Deep and Hard Rock Environments: Feasibility of Ultra-High-Speed Diamond Drilling' for the period starting 30 June 2003 and concluding 31 March 2009. The accomplishments of Phases 1 and 2 are summarized as follows: (1) TerraTek reviewed applicable literature and documentation and convened a project kick-off meeting with Industry Advisors in attendance (see Black and Judzis); (2) TerraTek designed and planned Phase I bench scale experiments (See Black and Judzis). Improvements were made to the loading mechanism and the rotational speed monitoring instrumentation. New drill bit designs were developed to provided a more consistent product with consistent performance. A test matrix for the final core bit testing program was completed; (3) TerraTek concluded small-scale cutting performance tests; (4) Analysis of Phase 1 data indicated that there is decreased specific energy as the rotational speed increases; (5) Technology transfer, as part of Phase 1, was accomplished with technical presentations to the industry (see Judzis, Boucher, McCammon, and Black); (6) TerraTek prepared a design concept for the high speed drilling test stand, which was planned around the proposed high speed mud motor concept. Alternative drives for the test stand were explored; a high speed hydraulic motor concept was finally used; (7) The high speed system was modified to accommodate larger drill bits than originally planned; (8) Prototype mud turbine motors and the high speed test stand were used to drive the drill bits at high speed; (9) Three different rock types were used during the testing: Sierra White granite, Crab Orchard sandstone, and Colton sandstone. The drill bits used included diamond impregnated bits, a polycrystalline diamond compact (PDC) bit, a thermally stable PDC (TSP) bit, and a hybrid TSP and natural diamond bit; and (10) The drill bits were run at rotary speeds up to 5500 rpm and weight on bit (WOB) to 8000 lbf. During Phase 2, the ROP as measured in depth of cut per bit revolution generally increased with increased WOB. The performance was mixed with increased rotary speed, with the depth cut with the impregnated drill bit generally increasing and the TSP and hybrid TSP drill bits generally decreasing. The ROP in ft/hr generally increased with all bits with increased WOB and rotary speed. The mechanical specific energy generally improved (decreased) with increased WOB and was mixed with increased rotary speed.

(2) TerraTek designed and planned Phase I bench scale experiments. Some difficulties continue in obtaining ultra-high speed motors. Improvements have been made to the loading mechanism and the rotational speed monitoring instrumentation. New drill bit designs have been provided to vendors for production. A more consistent product is required to minimize the differences in bit performance. A test matrix for the final core bit testing program has been completed. (3) TerraTek is progressing through Task 3 ''Small-scale cutting performance tests''. (4) Significant testing has been performed on nine different rocks. (5) Bit balling has been observed on some rock and seems to be more pronounces at higher rotational speeds. (6) Preliminary analysis of data has been completed and indicates that decreased specific energy is required as the rotational speed increases (Task 4). This data analysis has been used to direct the efforts of the final testing for Phase I (Task 5). (7) Technology transfer (Task 6) has begun with technical presentations to the industry (see Judzis).

Brine and Gas Flow Patterns Between Excavated Areas and Disturbed Rock Zone in the 1996 Performance Assessment for the Waste Isolation Pilot Plant for a Single Drilling Intrusion that Penetrates Repository and Castile Brine Reservoir  

SciTech Connect

The Waste Isolation Pilot Plant (WIPP), which is located in southeastern New Mexico, is being developed for the geologic disposal of transuranic (TRU) waste by the U.S. Department of Energy (DOE). Waste disposal will take place in panels excavated in a bedded salt formation approximately 2000 ft (610 m) below the land surface. The BRAGFLO computer program which solves a system of nonlinear partial differential equations for two-phase flow, was used to investigate brine and gas flow patterns in the vicinity of the repository for the 1996 WIPP performance assessment (PA). The present study examines the implications of modeling assumptions used in conjunction with BRAGFLO in the 1996 WIPP PA that affect brine and gas flow patterns involving two waste regions in the repository (i.e., a single waste panel and the remaining nine waste panels), a disturbed rock zone (DRZ) that lies just above and below these two regions, and a borehole that penetrates the single waste panel and a brine pocket below this panel. The two waste regions are separated by a panel closure. The following insights were obtained from this study. First, the impediment to flow between the two waste regions provided by the panel closure model is reduced due to the permeable and areally extensive nature of the DRZ adopted in the 1996 WIPP PA, which results in the DRZ becoming an effective pathway for gas and brine movement around the panel closures and thus between the two waste regions. Brine and gas flow between the two waste regions via the DRZ causes pressures between the two to equilibrate rapidly, with the result that processes in the intruded waste panel are not isolated from the rest of the repository. Second, the connection between intruded and unintruded waste panels provided by the DRZ increases the time required for repository pressures to equilibrate with the overlying and/or underlying units subsequent to a drilling intrusion. Third, the large and areally extensive DRZ void volumes is a significant source of brine to the repository, which is consumed in the corrosion of iron and thus contributes to increased repository pressures. Fourth, the DRZ itself lowers repository pressures by providing storage for gas and access to additional gas storage in areas of the repository. Fifth, given the pathway that the DRZ provides for gas and brine to flow around the panel closures, isolation of the waste panels by the panel closures was not essential to compliance with the U.S. Environment Protection Agency's regulations in the 1996 WIPP PA.

Workover well control. Part 3. Conventional rigs, snubbing units handle a variety of workover jobs  

SciTech Connect

The conventional rig, the most widely used rig for workovers, performs several common functions: tripping in and out of the hole, rotating the work string, and circulating fluid. Its primary component groups are the derrick, hoisting systems, rotary tools, circulating systems, and tubular goods. Rig sizing depends on the job requirements; the typical workover rig is a small-capacity, single unit used for concentric work. A workover rig's most important feature is its portability; compartmentalizing the rig permits transporting it offshore in packages smaller than 8000 lb and allows small cranes to replace derrick barges for loading operations.

Drilling Waste Management Fact Sheet: Offsite Disposal at Commercial  

NLE Websites -- All DOE Office Websites (Extended Search)

Commercial Disposal Facilities Commercial Disposal Facilities Fact Sheet - Commercial Disposal Facilities Although drilling wastes from many onshore wells are managed at the well site, some wastes cannot be managed onsite. Likewise, some types of offshore drilling wastes cannot be discharged, so they are either injected underground at the platform (not yet common in the United States) or are hauled back to shore for disposal. According to an American Petroleum Institute waste survey, the exploration and production segment of the U.S. oil and gas industry generated more than 360 million barrels (bbl) of drilling wastes in 1985. The report estimates that 28% of drilling wastes are sent to offsite commercial facilities for disposal (Wakim 1987). A similar American Petroleum Institute study conducted ten years later found that the volume of drilling waste had declined substantially to about 150 million bbl.

Proper planning improves flow drilling  

SciTech Connect

Underbalanced operations reduce formation damage, especially in horizontal wells where zones are exposed to mud for longer time periods. Benefits, risks, well control concerns, equipment and issues associated with these operations are addressed in this paper. Flow drilling raises many concerns, but little has been published on horizontal well control and flow drilling operations. This article covers planning considerations for flow drilling, but does not address horizontal ''overbalanced'' drilling because considerations and equipment are the same as in vertical overbalanced drilling and many references address that subject. The difference in well control between vertical and horizontal overbalanced drilling is fluid influx behavior and how that behavior affects kill operations.

Air drilling operations improved by percussion-bit/hammer-tool tandem  

SciTech Connect

Contractors and operators air drill whenever possible to improve rate of penetration (ROP). This is done with pneumatic hammer tools (HT's) and various bit types used with standard rotary air rigs. The recent application of a ''flat-bottomed'' percussion bit (FPB) combined with a custom-designed HT originally developed for mining operations has significantly improved air drilling operations in the Arkoma basin. The improvements include a large increase in ROP, improved hole geometry, reduced drillstring stresses, and a substantial reduction in cost per foot. This paper describes (1) a discussion of the engineering design and operation of the FPB/HT tandem, (2) applications and limitations of the tools, (3) guidelines for optimization of performance, and (4) documentation of field performance on Arkoma basin wells to demonstrate the improvements in air drilling operations.

To attain this goal, DOE continuously evaluates new technologies to determine their potential in contributing to the Program. One such technology is artifical intelligence (AI), a branch of computer science that, in recent years, has begun to impact the marketplace in a number of fields. Expert systems techniques can (and in some cases, already have) been applied to develop computer-based ''advisors'' to assist drilling personnel in areas such as designing mud systems, casing plans, and cement programs, optimizing drill bit selection and bottom hole asssembly (BHA) design, and alleviating lost circulation, stuck pipe, fishing, and cement problems. Intelligent machines with sensor and/or robotic directly linked to AI systems, have potential applications in areas of bit control, rig hydraulics, pipe handling, and pipe inspection. Using a well costing spreadsheet, the potential savings that could be attributed to each of these systems was calculated for three base cases: a dry steam well at The Geysers, a medium-depth Imerial Valley well, and a deep Imperial Valley well. Based on the average potential savings to be realized, expert systems for handling lost circulations problems and for BHA design are the most likely to produce significant results. Automated bit control and rig hydraulics also exhibit high potential savings, but these savings are extremely sensitive to the assumptions of improved drilling efficiency and the cost of these sytems at the rig. 50 refs., 19 figs., 17 tabs.

Natural Gas Summary from the Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

average $2.83 per MMBtu in 2002 compared with about $4.00 last year (Short-Term Energy Outlook, June 2002). Average wellhead prices have increased by nearly 50 percent from $2.09 per MMBtu in February to an estimated $3.11 per MMBtu in May. Spot prices at the Henry Hub have also increased, rising more than $1.00 per MMBtu since early February. It is atypical to see higher spot gas prices in the cooling season than during the heating season, particularly when working gas in underground storage is at high levels, as it has been for the past several months. As of the end of May, working gas levels were more than 20 percent above the previous 5-year average for that month. Moreover, gas-directed drilling, while down sharply from summer 2001 levels, is still quite strong from a historical perspective. The gas rig count as of May 31 was up 22 percent from the recent low of 591 for the week ending April 5.

Liability issues surrounding oil drilling mud sumps  

SciTech Connect

This presentation examines liability issues surrounding oil drilling mud sumps and discusses them in relation to two recent cases that arose in Ventura County, California. Following a brief history of regulatory interest in oil drilling mud and its common hazardous substances, various cause of action arising from oil drilling mud deposits are enumerated, followed by defenses to these causes of action. Section 8002 (m) of the Resource Conservation and Recovery Act is mentioned, as are constituents of oil and gas waste not inherent in petroleum and therefore not exempt from regulation under the petroleum exclusion in the Comprehensive Environmental Response, Compensation and Recovery Act. Key legal words such as hazardous substance, release, public and private nuisance, trespass, responsible parties, joint and several liability, negligence, and strict liability are explained. The effects on liability of knowledge of the deposits, duty to restore land to its original condition, consent to the deposit of oil drilling mud, and noncompliance and compliance with permit conditions are analyzed. The state-of-the-art defense and research to establish this defense are mentioned. The newly created cause of action for fear of increased risk of cancer is discussed. Issues on transfer of property where oil drilling mud has been deposited are explored, such as knowledge of prior owners being imputed to later owners, claims of fraudulent concealment, and as is' clauses. The effects on the oil and gas industry of the California Court of Appeals for the Second District rulings in Dolan v. Humacid-MacLeod and Stevens v. McQueen are speculated.

Laser Drilling - Drilling with the Power of Light  

SciTech Connect

Gas Technology Institute (GTI) has been the leading investigator in the field of high power laser applications research for well construction and completion applications. Since 1997, GTI (then as Gas Research Institute- GRI) has investigated several military and industrial laser systems and their ability to cut and drill into reservoir type rocks. In this report, GTI continues its investigation with a 5.34 kW ytterbium-doped multi-clad high power fiber laser (HPFL). When compared to its competitors; the HPFL represents a technology that is more cost effective to operate, capable of remote operations, and requires considerably less maintenance and repair. Work performed under this contract included design and implementation of laboratory experiments to investigate the effects of high power laser energy on a variety of rock types. All previous laser/rock interaction tests were performed on samples in the lab at atmospheric pressure. To determine the effect of downhole pressure conditions, a sophisticated tri-axial cell was designed and tested. For the first time, Berea sandstone, limestone and clad core samples were lased under various combinations of confining, axial and pore pressures. Composite core samples consisted of steel cemented to rock in an effort to represent material penetrated in a cased hole. The results of this experiment will assist in the development of a downhole laser perforation or side tracking prototype tool. To determine how this promising laser would perform under high pressure in-situ conditions, GTI performed a number of experiments with results directly comparable to previous data. Experiments were designed to investigate the effect of laser input parameters on representative reservoir rock types of sandstone and limestone. The focus of the experiments was on laser/rock interaction under confining pressure as would be the case for all drilling and completion operations. As such, the results would be applicable to drilling, perforation, and side tracking applications. In the past, several combinations of laser and rock variables were investigated at standard conditions and reported in the literature. More recent experiments determined the technical feasibility of laser perforation on multiple samples of rock, cement and steel. The fiber laser was capable of penetrating these materials under a variety of conditions, to an appropriate depth, and with reasonable energy requirements. It was determined that fiber lasers are capable of cutting rock without causing damage to flow properties. Furthermore, the laser perforation resulted in permeability improvements on the exposed rock surface. This report has been prepared in two parts and each part may be treated as a stand-alone document. Part 1 (High Energy Laser Drilling) includes the general description of the concept and focuses on results from experiments under the ambient lab conditions. Part 2 (High Energy Laser Perforation and Completion Techniques) discusses the design and development of a customized laser pressure cell; experimental design and procedures, and the resulting data on pressure-charged samples exposed to the laser beam. An analysis provides the resulting effect of downhole pressure conditions on the laser/rock interaction process.

Cost effectiveness of sonic drilling  

SciTech Connect

Sonic drilling (combination of mechanical vibrations and rotary power) is an innovative environmental technology being developed in cooperation with DOE`s Arid-Site Volatile Organic Compounds Integrated Demonstration at Hanford and the Mixed Waste Landfill Integrated Demonstration at Sandia. This report studies the cost effectiveness of sonic drilling compared with cable-tool and mud rotary drilling. Benefit of sonic drilling is its ability to drill in all types of formations without introducing a circulating medium, thus producing little secondary waste at hazardous sites. Progress has been made in addressing the early problems of failures and downtime.

Bailer for top head drive rotary well drills  

SciTech Connect

A bailer mounted to the derrick of a top head drive well drilling rig is described. The bailer includes a winch line drum mounted by a bracket to the derrick. A positive displacement hydraulic motor mounts one end of the drum and receives fluid under pressure from the existing hydraulic pressure supply. Valving is provided to allow reverse operation of the motor so equipment can either be raised or lowered relative to the derrick. The hydraulic delivery line to the motor includes a one way restrictor that will allow relatively free passage of fluid to the motor in a driving or lifting mode but will reverse flow of fluid from the motor, thereby affording a braking effect for lowering a load at a selected rate.

Microhole High-Pressure Jet Drill for Coiled Tubing  

SciTech Connect

Tempress Small Mechanically-Assisted High-Pressure Waterjet Drilling Tool project centered on the development of a downhole intensifier (DHI) to boost the hydraulic pressure available from conventional coiled tubing to the level required for high-pressure jet erosion of rock. We reviewed two techniques for implementing this technology (1) pure high-pressure jet drilling and (2) mechanically-assisted jet drilling. Due to the difficulties associated with modifying a downhole motor for mechanically-assisted jet drilling, it was determined that the pure high-pressure jet drilling tool was the best candidate for development and commercialization. It was also determined that this tool needs to run on commingled nitrogen and water to provide adequate downhole differential pressure and to facilitate controlled pressure drilling and descaling applications in low pressure wells. The resulting Microhole jet drilling bottomhole assembly (BHA) drills a 3.625-inch diameter hole with 2-inch coil tubing. The BHA consists of a self-rotating multi-nozzle drilling head, a high-pressure rotary seal/bearing section, an intensifier and a gas separator. Commingled nitrogen and water are separated into two streams in the gas separator. The water stream is pressurized to 3 times the inlet pressure by the downhole intensifier and discharged through nozzles in the drilling head. The energy in the gas-rich stream is used to power the intensifier. Gas-rich exhaust from the intensifier is conducted to the nozzle head where it is used to shroud the jets, increasing their effective range. The prototype BHA was tested at operational pressures and flows in a test chamber and on the end of conventional coiled tubing in a test well. During instrumented runs at downhole conditions, the BHA developed downhole differential pressures of 74 MPa (11,000 psi, median) and 90 MPa (13,000 psi, peaks). The median output differential pressure was nearly 3 times the input differential pressure available from the coiled tubing. In a chamber test, the BHA delivered up to 50 kW (67 hhp) hydraulic power. The tool drilled uncertified class-G cement samples cast into casing at a rate of 0.04 to 0.17 m/min (8 to 33 ft/hr), within the range projected for this tool but slower than a conventional PDM. While the tool met most of the performance goals, reliability requires further improvement. It will be difficult for this tool, as currently configured, to compete with conventional positive displacement downhole motors for most coil tubing drill applications. Mechanical cutters on the rotating nozzle head would improve cutting. This tool can be easily adapted for well descaling operations. A variant of the Microhole jet drilling gas separator was further developed for use with positive displacement downhole motors (PDM) operating on commingled nitrogen and water. A fit-for-purpose motor gas separator was designed and yard tested within the Microhole program. Four commercial units of that design are currently involved in a 10-well field demonstration with Baker Oil Tools in Wyoming. Initial results indicate that the motor gas separators provide significant benefit.

DEVELOPMENT OF NEW DRILLING FLUIDS  

SciTech Connect

The goal of the project has been to develop new types of drill-in fluids (DIFs) and completion fluids (CFs) for use in natural gas reservoirs. Phase 1 of the project was a 24-month study to develop the concept of advanced type of fluids usable in well completions. Phase 1 tested this concept and created a kinetic mathematical model to accurately track the fluid's behavior under downhole conditions. Phase 2 includes tests of the new materials and practices. Work includes the preparation of new materials and the deployment of the new fluids and new practices to the field. The project addresses the special problem of formation damage issues related to the use of CFs and DIFs in open hole horizontal well completions. The concept of a ''removable filtercake'' has, as its basis, a mechanism to initiate or trigger the removal process. Our approach to developing such a mechanism is to identify the components of the filtercake and measure the change in the characteristics of these components when certain cleanup (filtercake removal) techniques are employed.

Smaller Footprint Drilling System for Deep and Hard Rock Environments; Feasibility of Ultra-High-Speed Diamond Drilling  

SciTech Connect

The two phase program addresses long-term developments in deep well and hard rock drilling. TerraTek believes that significant improvements in drilling deep hard rock will be obtained by applying ultra-high rotational speeds (greater than 10,000 rpm). The work includes a feasibility of concept research effort aimed at development that will ultimately result in the ability to reliably drill ''faster and deeper'' possibly with smaller, more mobile rigs. The principle focus is on demonstration testing of diamond bits rotating at speeds in excess of 10,000 rpm to achieve high rate of penetration (ROP) rock cutting with substantially lower inputs of energy and loads. The significance of the ''ultra-high rotary speed drilling system'' is the ability to drill into rock at very low weights on bit and possibly lower energy levels. The drilling and coring industry today does not practice this technology. The highest rotary speed systems in oil field and mining drilling and coring today run less than 10,000 rpm-usually well below 5,000 rpm. This document details the progress at the end of Phase 1 on the program entitled ''Smaller Footprint Drilling System for Deep and Hard Rock Environments: Feasibility of Ultra-High-Speed Diamond Drilling'' for the period starting 1 March 2006 and concluding 30 June 2006. (Note: Results from 1 September 2005 through 28 February 2006 were included in the previous report (see Judzis, Black, and Robertson)). Summarizing the accomplished during Phase 1: {lg_bullet} TerraTek reviewed applicable literature and documentation and convened a project kickoff meeting with Industry Advisors in attendance (see Black and Judzis). {lg_bullet} TerraTek designed and planned Phase I bench scale experiments (See Black and Judzis). Some difficulties continued in obtaining ultra-high speed motors. Improvements were made to the loading mechanism and the rotational speed monitoring instrumentation. New drill bit designs were developed to provided a more consistent product with consistent performance. A test matrix for the final core bit testing program was completed. {lg_bullet} TerraTek concluded Task 3 ''Small-scale cutting performance tests.'' {sm_bullet} Significant testing was performed on nine different rocks. {sm_bullet} Five rocks were used for the final testing. The final tests were based on statistical design of experiments. {sm_bullet} Two full-faced bits, a small diameter and a large diameter, were run in Berea sandstone. {lg_bullet} Analysis of data was completed and indicates that there is decreased specific energy as the rotational speed increases (Task 4). Data analysis from early trials was used to direct the efforts of the final testing for Phase I (Task 5). {lg_bullet} Technology transfer (Task 6) was accomplished with technical presentations to the industry (see Judzis, Boucher, McCammon, and Black).

Simulation of air and mist drilling for geothermal wells  

SciTech Connect

An air drilling model has been developed that accounts for cuttings and mist. Comparison of the model results with previous work shows this model to be more conservative. The equations developed are simple enough to be used in hand calculations, but the full capability of the model is more easily obtained with a computer program. Studies with the model show that volume requirements and standpipe pressures are significantly different for mist drilling compared with air drilling. An improved method for calculating downhole temperatures, pressures, fluid densities, and velocities during air drilling has been developed. Improvements on previous methods include the following. A fully transient thermal analysis of the wellbore and formation is used to determine the flowing temperatures. The effects of flow acceleration are included explicitly in the calculation. The slip velocity between the gas and the cuttings is determined by the use of a separate momentum equation for the cuttings. The possibility of critical flow in the wellbore is tested and appropriate changes in the volume flow rate and standpipe pressure are made automatically. The standpipe and flowing pressures are predicted. The analysis is conservative. The effect of the cuttings on the wellbore flow will tend to overpredict the required volume flow rates. In this paper, the basic equations of fluid flow for a gas with cuttings and mist are presented along with a numerical method for their solution. Several applications of this calculational method are given, showing the effect of flow rate and standpipe pressure in typical air and mist drilling situations.

NETL: News Release - New Seismic Technology Improves Pre-Drill Diagnostics  

NLE Websites -- All DOE Office Websites (Extended Search)

June 12, 2007 June 12, 2007 New Seismic Technology Improves Pre-Drill Diagnostics for Deep Oil and Gas Reservoirs WASHINGTON, DC - New technology developed through a cost-shared project managed by the Office of Fossil Energy's National Energy Technology Laboratory is improving industry's ability to identify commercially viable deep oil and gas targets prior to drilling. Applications of this groundbreaking technology will help to accelerate future development of deep oil and gas resources in the United States. As the oil and gas industry turns its attention toward deeper targets, particularly in the Gulf of Mexico, the tremendous costs involved require advanced technologies for pre-drill evaluation of a deep prospect's location, size, and hydrocarbon charge. Rock Solid Images, of Houston, Texas, answered the call with their much-needed pre-drill seismic imaging technology. The patented new technology improves pre-drill oil and gas detection in the reservoir and reduces the risks associated with drilling deep wells. With a significant portion of the Nation's oil and natural gas resource trapped in deep reservoirs, the new seismic technology represents a much-needed improvement that should bring more deep oil and gas to market.

Evaluation of target reservoirs for horizontal drilling: Lower Glen Rose Formation, South Texas  

SciTech Connect

The primary objective of this project is to test the hypothesis that a horizontally drilled borehole can increase gas production sufficiently from the Lower Glen Rose Formation to provide an economic advantage over conventional vertical drilling. Additional objectives are to conduct detailed investigations of reservoir properties and completion methods. This paper presents preliminary results of a project, co-funded by PrimeEnergy and the United States Department of Energy (DOE), to assess the economic viability of horizontal drilling in the Lower Glen Rose Formation of Maverick County, Texas. This project is part of an ongoing DOE investigation of directional drilling in the development of tight gas resources within the United States. This paper builds on data presented in Muncey (1992) with data from two vertical tests of the Lower Glen Rose Formation, both drilled in 1993, and the analysis of approximately 20 line-miles of high-resolution seismic data recorded in 1992 and 1993.

1982 geothermal well drilling summary  

SciTech Connect

This summary lists all geothermal wells spudded in 1982, which were drilled to a depth of at least 2,000 feet. Tables 1 and 2 list the drilling information by area, operator, and well type. For a tabulation of all 1982 geothermal drilling activity, including holes less than 2,000 feet deep, readers are referred to the February 11, 1983, issue of Petroleum Information's ''National Geothermal Service.'' The number of geothermal wells drilled in 1982 to 2,000 feet or more decreased to 76 wells from 99 ''deep'' wells in 1981. Accordingly, the total 1982 footage drilled was 559,110 feet of hole, as compared to 676,127 feet in 1981. Most of the ''deep'' wells (49) completed were drilled for development purposes, mainly in The Geysers area of California. Ten field extension wells were drilled, of which nine were successful. Only six wildcat wells were drilled compared to 13 in 1980 and 20 in 1981, showing a slackening of exploration compared to earlier years. Geothermal drilling activity specifically for direct use projects also decreased from 1981 to 1982, probably because of the drastic reduction in government funding and the decrease in the price of oil. Geothermal power generation in 1982 was highlighted by (a) an increase of 110 Mw geothermal power produced at The Geysers (to a total of 1,019 Mw) by addition of Unit 17, and (b) by the start-up of the Salton Sea 10 Mw single flash power plant in the Imperial Valley, which brought the total geothermal electricity generation in this area to 31 Mw.

An approach for assessing engineering risk from shale gas wells in the United States  

Science Journals Connector (OSTI)

Abstract In response to a series of “energy crises” in the 1970s, the United States government began investigating the potential of unconventional, domestic sources of energy to offset imported oil. Hydraulic fracturing applied to vertical tight sand and coal bed methane wells achieved some degree of success during a period of high energy prices in the early 1980s, but shale gas remained largely untapped until the late 1990s with the application of directional drilling, a mature technology adapted from deepwater offshore platforms that allowed horizontal wells to penetrate kilometers of organic-rich shale, and staged hydraulic fracturing, which created high permeability flowpaths from the horizontal wells into a much greater volume of the target formations than previous completion methods. These new engineering techniques opened up vast unconventional natural gas and oil reserves, but also raised concerns about potential environmental impacts. These include short-term and long-term impacts to air and water quality from rig operations, potential migration of gas, fluids and chemicals through the ground, and effects on small watersheds and landscapes from roads, pads and other surface structures. Engineering risk assessment commonly uses integrated assessment models (IAMs), which define sources of risk from features, events and processes. The risk from each system element is assessed using high-fidelity models. Output from these is simplified into reduced-order models, so that a large, integrated site performance assessment can be run using the IAM. The technique has been applied to engineered systems in geologic settings for sequestering carbon dioxide, and it is also applicable to shale gas, albeit with some modifications of the various system elements. Preliminary findings indicate that shale gas well drilling and hydraulic fracturing techniques are generally safe when properly applied. Incident reports recorded by state environmental agencies suggest that human error resulting from the disregard of prescribed practices is the greatest cause of environmental incidents. This can only be addressed through education, regulations and enforcement.

Laser Drilling - Drilling with the Power of Light  

SciTech Connect

Gas Technology Institute (GTI) has been the leading investigator in the field of high power laser applications research for well construction and completion applications. Since 1997, GTI (then as Gas Research Institute) has investigated several military and industrial laser systems and their ability to cut and drill into reservoir type rocks. In this report, GTI continues its investigation with a recently acquired 5.34 kW ytterbium-doped multi-clad high power fiber laser (HPFL). The HPFL represents a potentially disruptive technology that, when compared to its competitors, is more cost effective to operate, capable of remote operations, and requires considerably less maintenance and repair. To determine how this promising laser would perform under high pressure in-situ conditions, GTI performed a number of experiments with results directly comparable to previous data. Experiments were designed to investigate the effect of laser input parameters on representative reservoir rock types of sandstone and limestone. The focus of the experiments was on completion and perforation applications, although the results and techniques apply to well construction and other rock cutting applications. All previous laser/rock interaction tests were performed on samples in the lab at atmospheric pressure. To determine the effect of downhole pressure conditions, a sophisticated tri-axial cell was designed and tested. For the first time, Berea sandstone, limestone and clad core samples were lased under various combinations of confining, axial and pore pressures. Composite core samples consisted of steel cemented to rock in an effort to represent material penetrated in a cased hole. The results of this experiment will assist in the development of a downhole laser perforation prototype tool. In the past, several combinations of laser and rock variables were investigated at standard conditions and reported in the literature. More recent experiments determined the technical feasibility of laser perforation on multiple samples of rock, cement and steel. The fiber laser was capable of penetrating these materials under a variety of conditions, to an appropriate depth, and with reasonable energy requirements. It was determined that fiber lasers are capable of cutting rock without causing damage to flow properties. Furthermore, the laser perforation resulted in permeability improvements on the exposed rock surface. This report discusses the design and development of a customized laser pressure cell; experimental design and procedures, and the resulting data on pressure-charged samples exposed to the laser beam. An analysis provides the resulting effect of downhole pressure conditions on the laser/rock interaction process.

Forecast of geothermal drilling activity  

SciTech Connect

The numbers of each type of geothermal well expected to be drilled in the United States for each 5-year period to 2000 AD are specified. Forecasts of the growth of geothermally supplied electric power and direct heat uses are presented. The different types of geothermal wells needed to support the forecasted capacity are quantified, including differentiation of the number of wells to be drilled at each major geothermal resource for electric power production. The rate of growth of electric capacity at geothermal resource areas is expected to be 15 to 25% per year (after an initial critical size is reached) until natural or economic limits are approached. Five resource areas in the United States should grow to significant capacity by the end of the century (The Geysers; Imperial Valley; Valles Caldera, NM; Roosevelt Hot Springs, UT; and northern Nevada). About 3800 geothermal wells are expected to be drilled in support of all electric power projects in the United States between 1981 and 2000 AD. Half of the wells are expected to be drilled in the Imperial Valley. The Geysers area is expected to retain most of the drilling activity for the next 5 years. By the 1990's, the Imperial Valley is expected to contain most of the drilling activity.

Tool Wear in Friction Drilling  

SciTech Connect

This study investigated the wear of carbide tools used in friction drilling, a nontraditional hole-making process. In friction drilling, a rotating conical tool uses the heat generated by friction to soften and penetrate a thin workpiece and create a bushing without generating chips. The wear of a hard tungsten carbide tool used for friction drilling a low carbon steel workpiece has been investigated. Tool wear characteristics were studied by measuring its weight change, detecting changes in its shape with a coordinate measuring machine, and making observations of wear damage using scanning electron microscopy. Energy dispersive spectroscopy was applied to analyze the change in chemical composition of the tool surface due to drilling. In addition, the thrust force and torque during drilling and the hole size were measured periodically to monitor the effects of tool wear. Results indicate that the carbide tool is durable, showing minimal tool wear after drilling 11000 holes, but observations also indicate progressively severe abrasive grooving on the tool tip.

Vibratory Drilling of Oil Wells  

Science Journals Connector (OSTI)

Vibratory drilling refers to the process of drilling into rock by vibrating the drilling tool at audio?frequencies. The basic mechanism of vibratory drilling was ascertained by preliminary laboratory experimentation to consist of a series of impacts on the rock at the frequency of vibration. A fundamental study of this basic mechanism made by dropping weighted chisels on rock showed that the primary parameter which determined the rate of penetration was the mechanical power input to the rock per unit cross section of hole; the values of the vibration frequency and of other variables were of minor consequence over wide ranges. A theoretical analysis was made of the vibration of an elongated magnetostrictiontransducer capable of generating the required power level taking into account the distributed nature of the generation of vibrations. Intermediate power transducers have been built and tested and a high?power transducer for down?hole operation is under construction. [The material for this presentation is based on work carried out at the Battelle Memorial Institute under the sponsorship of Drilling Research Inc. an organization formed by a group of major companies engaged in various phases of oil production for the purpose of investigating novel methods of rock drilling.

Recovery Efficiency Test Project: Phase 1, Activity report. Volume 1: Site selection, drill plan preparation, drilling, logging, and coring operations  

SciTech Connect

The recovery Efficiency Test well project addressed a number of technical issues. The primary objective was to determine the increased efficiency gas recovery of a long horizontal wellbore over that of a vertical wellbore and, more specifically, what improvements can be expected from inducing multiple hydraulic fractures from such a wellbore. BDM corporation located, planned, and drilled a long radius turn horizontal well in the Devonian shale Lower Huron section in Wayne County, West Virginia, demonstrating that state-of-the-art technology is capable of drilling such wells. BDM successfully tested drilling, coring, and logging in a horizontal well using air as the circulating medium; conducted reservoir modeling studies to protect flow rates and reserves in advance of drilling operations; observed two phase flow conditions in the wellbore not observed previously; cored a fracture zone which produced gas; observed that fractures in the core and the wellbore were not systematically spaced (varied from 5 to 68 feet in different parts of the wellbore); observed that highest gas show rates reported by the mud logger corresponded to zone with lowest fracture spacing (five feet) or high fracture frequency. Four and one-half inch casting was successfully installed in the borehole and was equipped to isolate the horizontal section into eight (8) zones for future testing and stimulation operations. 6 refs., 48 figs., 10 tabs.

Drilling problems don't slow Williston basin operators  

SciTech Connect

In spite of the Williston basin's tough drilling environment, exploration activity has continued to increase, especially around northwestern North Dakota's Nesson anticline. The foremost drilling problem is the Charles slat section, which lies 8000-9000 ft deep; this section requires a salt-saturated mud system with additives, a heavyweight pipe, and a careful cementing job. Nevertheless, big discoveries - such as Texaco Inc.'s gas well in McKenzie Co., which tested at 9.9 million CF/day and 179 bbl/day of condensate - will spur exploration for some time since most of the basin remains untouched. Moreover, drilling engineers will soon be able to mitigate, if not eliminate, the typical difficulties encountered.

Downhole Temperature Prediction for Drilling Geothermal Wells  

SciTech Connect

Unusually high temperatures are encountered during drilling of a geothermal well. These temperatures affect every aspect of drilling, from drilling fluid properties to cement formulations. Clearly, good estimates of downhole temperatures during drilling would be helpful in preparing geothermal well completion designs, well drilling plans, drilling fluid requirements, and cement formulations. The thermal simulations in this report were conducted using GEOTEMP, a computer code developed under Sandia National Laboratories contract and available through Sandia. Input variables such as drilling fluid inlet temperatures and circulation rates, rates of penetration, and shut-in intervals were obtained from the Imperial Valley East Mesa Field and the Los Alamos Hot Dry Rock Project. The results of several thermal simulations are presented, with discussion of their impact on drilling fluids, cements, casing design, and drilling practices.

Steerable BHAs drill storage wells with difficult trajectories. [Bottom Hole Assembly  

SciTech Connect

The use of steerable downhole motor assemblies allows greater variation in well bore trajectory for drilling gas and oil storage wells in salt domes in areas with surface site restrictions. With modern directional drilling tools, the cavern wells are drilled vertically, kicked off in an S turn, and then finished with a vertical section. The last 100 m of a cavern well above the last cemented casing shoe must be vertical because of the technical demands of brining and completion. To date, Kavernen Bauund Betriebs-GmbH has successfully drilled and completed three directional cavern boreholes in Germany. These directional drilling techniques have also been used successfully for vertical boreholes with strict deviation limits. The paper describes this technology.

U. S. rig count drops below 600, a post-1940 low  

SciTech Connect

This paper reports that the Baker Hughes Inc. count of active U.S. rotary rigs as of June 12 fell to less than 600 the first time since that tally began in 1940. The previous modern record low was set at 610 the previous week. Baker Hughes reported about 1,400 rigs idle in the U.S. last week. Using a different criteria, the Smith International count of U.S. active rigs fell seven units to 653 the week ended June 12, compared with a count of 910 the previous year. Baker Hughes predecessor Hughes Tool Co. began keeping monthly records of active U.S. rigs in January 1940. The lowest monthly count that year was 857. It changed to a weekly count in January 1949. The milestone was met wit calls for relief for the U.S. upstream sector from industry and government officials in Washington.

Remote arctic drilling operations in Russia, case history of Ardalin field operations, Timan Pechora Basin  

SciTech Connect

In developing the Ardalin field, the Polar Lights Company merged Russian and western expertise to conduct drilling operations in a hostile and ecologically sensitive arctic tundra environment. The field is located above the Arctic Circle in northern Russia. The nearest Russian road system is over 60km away and the nearest railhead is 240 km from the field. Three Russian rigs were constructed with selected western upgrades, twelve development wells were drilled, and three existing Russian wells were worked over within a 24 month period. Operations were supported with a snow road in the winter season and Russian helicopter in the summer season. All materials for one year`s worth of drilling had to be transported to the field prior to break-up (end of trucking activities on the snow roads). Services and equipment were sourced from both inside and outside of the Commonwealth of Independent States (CIS). Temperatures in winter reached -45{degrees}C. The field is located in one of the most ecologically sensitive areas in the world, and numerous precautions were taken for the protection of the environment. Russian operating philosophies were successfully merged with western practices. This paper will focus on the operational criteria initiated and infrastructure system that evolved to support this project.

Microhole Drilling Tractor Technology Development  

SciTech Connect

In an effort to increase the U.S. energy reserves and lower costs for finding and retrieving oil, the USDOE created a solicitation to encourage industry to focus on means to operate in small diameter well-Microhole. Partially in response to this solicitation and because Western Well Tool's (WWT) corporate objective to develop small diameter coiled tubing drilling tractor, WWT responded to and was awarded a contract to design, prototype, shop test, and field demonstrate a Microhole Drilling Tractor (MDT). The benefit to the oil industry and the US consumer from the project is that with the MDT's ability to facilitate Coiled Tubing drilled wells to be 1000-3000 feet longer horizontally, US brown fields can be more efficiently exploited resulting in fewer wells, less environmental impact, greater and faster oil recovery, and lower drilling costs. Shortly after award of the contract, WWT was approached by a major oil company that strongly indicated that the specified size of a tractor of 3.0 inches diameter was inappropriate and that immediate applications for a 3.38-inch diameter tractor would substantially increase the usefulness of the tool to the oil industry. Based on this along with an understanding with the oil company to use the tractor in multiple field applications, WWT applied for and was granted a no-cost change-of-scope contract amendment to design, manufacture, assemble, shop test and field demonstrate a prototype a 3.38 inch diameter MDT. Utilizing existing WWT tractor technology and conforming to an industry developed specification for the tool, the Microhole Drilling Tractor was designed. Specific features of the MDT that increase it usefulness are: (1) Operation on differential pressure of the drilling fluid, (2) On-Off Capability, (3) Patented unique gripping elements (4) High strength and flexibility, (5) Compatibility to existing Coiled Tubing drilling equipment and operations. The ability to power the MDT with drilling fluid results in a highly efficient tool that both delivers high level of force for the pressure available and inherently increases downhole reliability because parts are less subject to contamination. The On-Off feature is essential to drilling to allow the Driller to turn off the tractor and pull back while circulating in cleanout runs that keep the hole clean of drilling debris. The gripping elements have wide contact surfaces to the formation to allow high loads without damage to the formation. As part of the development materials evaluations were conducted to verify compatibility with anticipated drilling and well bore fluids. Experiments demonstrated that the materials of the tractor are essentially undamaged by exposure to typical drilling fluids used for horizontal coiled tubing drilling. The design for the MDT was completed, qualified vendors identified, parts procured, received, inspected, and a prototype was assembled. As part of the assembly process, WWT prepared Manufacturing instructions (MI) that detail the assembly process and identify quality assurance inspection points. Subsequent to assembly, functional tests were performed. Functional tests consisted of placing the MDT on jack stands, connecting a high pressure source to the tractor, and verifying On-Off functions, walking motion, and operation over a range of pressures. Next, the Shop Demonstration Test was performed. An existing WWT test fixture was modified to accommodate operation of the 3.38 inch diameter MDT. The fixture simulated the tension applied to a tractor while walking (pulling) inside 4.0 inch diameter pipe. The MDT demonstrated: (1) On-off function, (2) Pulling forces proportional to available differential pressure up to 4000 lbs, (3) Walking speeds to 1100 ft/hour. A field Demonstration of the MDT was arranged with a major oil company operating in Alaska. A demonstration well with a Measured Depth of approximately 15,000 ft was selected; however because of problems with the well drilling was stopped before the planned MDT usage. Alternatively, functional and operational tests were run with the MDT insi

Optical coherence tomography guided dental drill  

DOE Patents (OSTI)

A dental drill that has one or multiple single mode fibers that can be used to image in the vicinity of the drill tip. It is valuable to image below the surface being drilled to minimize damage to vital or normal tissue. Identifying the boundary between decayed and normal enamel (or dentine) would reduce the removal of viable tissue, and identifying the nerve before getting too close with the drill could prevent nerve damage. By surrounding a drill with several optical fibers that can be used by an optical coherence domain reflectometry (OCDR) to image several millimeters ahead of the ablation surface will lead to a new and improved dental treatment device.

A study of geothermal drilling and the production of electricity from geothermal energy  

SciTech Connect

This report gives the results of a study of the production of electricity from geothermal energy with particular emphasis on the drilling of geothermal wells. A brief history of the industry, including the influence of the Public Utilities Regulatory Policies Act, is given. Demand and supply of electricity in the United States are touched briefly. The results of a number of recent analytical studies of the cost of producing electricity are discussed, as are comparisons of recent power purchase agreements in the state of Nevada. Both the costs of producing electricity from geothermal energy and the costs of drilling geothermal wells are analyzed. The major factors resulting in increased cost of geothermal drilling, when compared to oil and gas drilling, are discussed. A summary of a series of interviews with individuals representing many aspects of the production of electricity from geothermal energy is given in the appendices. Finally, the implications of these studies are given, conclusions are presented, and program recommendations are made.

Innovative approach for restoring coastal wetlands using treated drill cuttings  

SciTech Connect

The leading environmental problem facing coastal Louisiana regions is the loss of wetlands. Oil and gas exploration and production activities have contributed to wetland damage through erosion at numerous sites where canals have been cut through the marsh to access drilling sites. An independent oil and gas producer, working with Southeastern Louisiana University and two oil field service companies, developed a process to stabilize drill cuttings so that they could be used as a substrate to grow wetlands vegetation. The U.S. Department of Energy (DOE) funded a project under which the process would be validated through laboratory studies and field demonstrations. The laboratory studies demonstrated that treated drill cuttings support the growth of wetlands vegetation. However, neither the Army Corps of Engineers (COE) nor the U.S. Environmental Protection Agency (EPA) would grant regulatory approval for afield trial of the process. Argonne National Laboratory was asked to join the project team to try to find alternative mechanisms for gaining regulatory approval. Argonne worked with EPA's Office of Reinvention and learned that EPA's Project XL would be the only regulatory program under which the proposed field trial could be done. One of the main criteria for an acceptable Project XL proposal is to have a formal project sponsor assume the responsibility and liability for the project. Because the proposed project involved access to private land areas, the team felt that an oil and gas company with coastal Louisiana land holdings would need to serve as sponsor. Despite extensive communication with oil and gas companies and industry associations, the project team was unable to find any organization willing to serve as sponsor. In September 1999, the Project XL proposal was withdrawn and the project was canceled.

DEVELOPMENT AND TESTING OF UNDERBALANCED DRILLING PRODUCTS. Final Report, Oct 1995 - July 2001  

SciTech Connect

Underbalanced drilling is experiencing growth at a rate that rivals that of horizontal drilling in the mid-1980s and coiled-tubing drilling in the 1990s. Problems remain, however, for applying underbalanced drilling in a wider range of geological settings and drilling environments. This report addresses developments under this DOE project to develop products aimed at overcoming these problems. During Phase I of the DOE project, market analyses showed that up to 12,000 wells per year (i.e., 30% of all wells) will be drilled underbalanced in the U.S.A. within the next ten years. A user-friendly foam fluid hydraulics model (FOAM) was developed for a PC Windows environment during Phase I. FOAM predicts circulating pressures and flow characteristics of foam fluids used in underbalanced drilling operations. FOAM is based on the best available mathematical models, and was validated through comparison to existing models, laboratory test data and field data. This model does not handle two-phase flow or air and mist drilling where the foam quality is above 0.97. This FOAM model was greatly expanded during Phase II including adding an improved foam rheological model and a ''matching'' feature that allows the model to be field calibrated. During Phase I, a lightweight drilling fluid was developed that uses hollow glass spheres (HGS) to reduce the density of the mud to less than that of water. HGS fluids have several advantages over aerated fluids, including they are incompressible, they reduce corrosion and vibration problems, they allow the use of mud-pulse MWD tools, and they eliminate high compressor and nitrogen costs. Phase II tests showed that HGS significantly reduce formation damage with water-based drilling and completion fluids and thereby potentially can increase oil and gas production in wells drilled with water-based fluids. Extensive rheological testing was conducted with HGS drilling and completion fluids during Phase II. These tests showed that the HGS fluids act similarly to conventional fluids and that they have potential application in many areas, including underbalanced drilling, completions, and riserless drilling. Early field tests under this project are encouraging. These led to limited tests by industry (which are also described). Further field tests and cost analyses are needed to demonstrate the viability of HGS fluids in different applications. Once their effectiveness is demonstrated, they should find widespread application and should significantly reduce drilling costs and increase oil and gas production rates. A number of important oilfield applications for HGS outside of Underbalanced Drilling were identified. One of these--Dual Gradient Drilling (DGD) for deepwater exploration and development--is very promising. Investigative work on DGD under the project is reported, along with definition of a large joint-industry project resulting from the work. Other innovative products/applications are highlighted in the report including the use of HGS as a cement additive.

Drilling Waste Management Fact Sheet: Discharge to Ocean  

NLE Websites -- All DOE Office Websites (Extended Search)

Discharge to Ocean Discharge to Ocean Fact Sheet - Discharge to Ocean Past Practices In early offshore oil and gas development, drilling wastes were generally discharged from the platforms directly to the ocean. Until several decades ago, the oceans were perceived to be limitless dumping grounds. During the 1970s and 1980s, however, evidence mounted that some types of drilling waste discharges could have undesirable effects on local ecology, particularly in shallow water. When water-based muds (WBMs) were used, only limited environmental harm was likely to occur, but when operators employed oil-based muds (OBMs) on deeper sections of wells, the resulting cuttings piles created impaired zones beneath and adjacent to the platforms. At some North Sea locations, large piles of oil-based cuttings remain on the sea floor near the platforms. Piles of oil-based cuttings can affect the local ecosystem in three ways: by smothering organisms, by direct toxic effect of the drilling waste, and by anoxic conditions caused by microbial degradation of the organic components in the waste. Current regulatory controls minimize the impacts of permitted discharges of cuttings.

View on Wikipedia Wikipedia Definition Geothermal Exploration is the exploration of the subsurface in search of viable active geothermal regions with the goal of building a geothermal power plant, where hot fluids drive turbines to create electricity. Exploration methods include a broad range of disciplines including geology, geophysics, geochemistry and engineering. Geothermal regions with adequate heat flow to fuel power plants are found in rift zones, subduction zones and mantle plumes. Hot spots are characterized by four geothermal elements. An active region will have: Heat Source - Shallow
