Plant construction and community stress  

SciTech Connect

Reports on a study commissioned by EPRI's Energy Analysis and Environment Division to acquire a better understanding of the power plant construction process and the socioeconomic impacts it can bring about. Points out that because of a parallel study the NRC conducted involving nuclear plants, the EPRI study's emphasis was on coal-fired power plants, which represented 9 of the 12 case studies. Finds that the impacts on communities near the case study plants were considerably less than had been forecast. Emphasizes that improper socioeconomic assessment procedures and poor mitigation planning can contribute to costly construction delays and lower construction worker productivity.

Plant construction and community stress  

SciTech Connect

Communities and utilities can project the impact of construction workers, their families, and the services they require before a project begins and take steps to mitigate any negative effects. Systematic socio-economic assessment is only a decade old, but has gradually taken on the importance of environmental impact assessments. An Electric Power Research Institute (EPRI) assessment of 12 case-study plants and their impact on neighboring communities found that population influx was more moderate than expected because of an indigenous work force, the willingness of new workers to drive long distances rather than relocate, and the shift in construction crafts required during the construction phase. Economic impacts were often more positive than expected. The study also underscored the need for proper assessment and appropriate mitigation planning. 2 references. (DCK)

Nuclear plant construction and investment risk  

SciTech Connect

Escalated cost estimations, delays and cancellations in nuclear construction have caused a preoccupation with the risks of nuclear power plant construction that dominates utility stock investment, overshadowing increased earnings per share and recent growth in production. The issue will be resolved when increased power demand requires new construction, but the effect has so far been to erode the economic advantage of nuclear power and threaten the ability of utilities to get rate increases high enough to cover their costs. Projected delays and cost escalations and their effects must go into an economic appraisal of the investment risks.

Analysis of nuclear power plant construction costs  

SciTech Connect

The objective of this report is to present the results of a statistical analysis of nuclear power plant construction costs and lead-times (where lead-time is defined as the duration of the construction period), using a sample of units that entered construction during the 1966-1977 period. For more than a decade, analysts have been attempting to understand the reasons for the divergence between predicted and actual construction costs and lead-times. More importantly, it is rapidly being recognized that the future of the nuclear power industry rests precariously on an improvement in the cost and lead-time situation. Thus, it is important to study the historical information on completed plants, not only to understand what has occurred to also to improve the ability to evaluate the economics of future plants. This requires an examination of the factors that have affected both the realized costs and lead-times and the expectations about these factors that have been formed during the construction process. 5 figs., 22 tabs.

Conoco's new approach to drill site construction in difficult, remote, swamp and jungle terrain Irian Jaya, Indonesia  

SciTech Connect

In October 1982, Conoco Irian Jaya as operator: and partners: Pertamina, Inpex Bintuni Limited, and Moeco Irian Jaya Company, mobilized construction equipment from Singapore to the KBS ''A'' contract area in Irian Jaya, Indonesia for the purpose of constructing a base camp and drill three exploratory sites. What made this construction effort different from others previously used in Irian Jaya; was that it incorporated several new and unique features, namely: a turnkey approach to construction; that is Conoco providing complete set of specifications and conditions with contractor assuming risks for a lump sum payment; special equipment designed by contractor for Irian Jaya operations; an incentive to co pensate or penalize contractor for helicopter hours flown below or above a predetermined number; structural steel pile platform designs for two swamp locations (Ayot and Aum), as opposed to the more conventional corduroy timber log-plank arrangement; and drilling rig pads designed for specific heli-rig with limited extra space. All work was successfully completed within the time frame stipulated in the contract, that is five months from the time the contractor was notified to begin mobilization of equipment, materials and personnel.

Toshiba's developments on construction techniques of nuclear power plants  

SciTech Connect

Reliable and economic energy supplies are fundamental requirements of energy policies in Japan. To accomplish these needs, nuclear power plants are being increased in Japan. In recent years, construction cost increases and schedule extensions have affected the capital cost of nuclear energy, compared with fossil power plants, due to lower costs of oil and coal. On the other hand, several severe regulations have been applied to nuclear power plant designs. High-quality and cooperative engineering and harmonized design of equipment and parts are strongly required. Therefore, reduced construction costs and scheduling, as well as higher quality and reliability, are the most important items for nuclear industry. Toshiba has developed new construction techniques, as well as design and engineering tools for control and management, that demonstrate the positive results achieved in the shorter construction period of 1100-MW(electric) nuclear power plants. The normal construction period so far is 64 months, whereas the current construction period is 52 months. (New construction techniques are partially applied). In future years, the construction period will be lowered to 48 months. (New construction techniques are fully applied). A construction period is defined as time from the start of rock inspection to the start of commercial operation.

Power plant construction: productivity and construction period. [Simulation with BOOM1 model  

SciTech Connect

Power plant capital costs become quite excessive with poor construction labor productivity. Building a power plant often creates a boom town or rapid-population-growth area. Rapid-growth conditions cause housing and service shortages, lowering the quality of living conditions in the area. One purpose for the research is to determine the effects of local living conditions on construction worker productivity. Results indicate the quality of local living conditions do not primarily affect construction worker productivity; other factors have greater influence. Research showed: (1) most construction workers can be induced to work in a boom-town situation, and (2) most construction workers will not become appreciably less productive in a situation of poor living conditions. If jobsite productivity does decrease, the decrease should be accredited to the poor-quality labor hired onto the jobsite. Results indicate that, for most power plant construction, productivity related cost decreases would be much less than interest and escalation cost increases when extending construction period. Power plant capital cost would increase when extending the construction schedule. However, under extreme conditions of very poor labor availability, extending the scheduled construction period may reduce total cost.

The wastewater from various stages of the existing purification process has been treated with electron beam in this plant, and it gave rise to elaborate the optimal technology of the electron beam treatment of wastewater with increased reliability at instant changes in the composition of wastewater. Installation of the e-beam pilot plant resulted in decolorizing and destructive oxidation of organic impurities in wastewater, appreciable to reduction of chemical reagent consumption, in reduction of the treatment time, and in increase in flow rate limit of existing facilities by 30-40%. Industrial plant for treating 10,000 m3/day, based upon the pilot experimental result, is under construction and will be finished by 2005. This project is supported by the International Atomic Energy Agency (IAEA) and Korean Government.

Risk Framework for the Next Generation Nuclear Power Plant Construction  

E-Print Network (OSTI)

Uncertainty can be either an opportunity or a risk. Every construction project begins with the expectation of project performance. To meet the expectation, construction projects need to be managed through sound risk assessment and management beginning with the front-end of the project life cycle to check the feasibility of a project. The Construction Industry Institutes (CII) International Project Risk Assessment (IPRA) tool has been developed, successfully used for a variety of heavy industry sector projects, and recently elevated to Best Practice status. However, its current format is inadequate to address the unique challenges of constructing the next generation of nuclear power plants (NPP). To understand and determine the risks associated with NPP projects, the goal of this thesis is to develop tailored risk framework for NPP projects that leverages and modifies the existing IPRA process. The IPRA has 82 elements to assess the risks associated with international construction projects. The modified IPRA adds five major issues (elements) to consider the unique risk factors of typical NPP projects based upon a review of the literature and an evaluation of the performance of previous nuclear-related facilities. The modified IPRA considers the sequence of NPP design that ultimately impacts the risks associated with plant safety and operations. Historically, financial risks have been a major chronic problem with the construction of NPPs. This research suggests that unstable regulations and the lack of design controls and oversight are significant risk issues. This thesis includes a consistency test to initially validate whether the asserted risks exist in actual conditions. Also, an overall risk assessment is performed based on the proposed risk framework for NPP and the list of assessed risk is proposed through a possible scenario. After the assessment, possible mitigation strategies are also provided against the major risks as a part of this thesis. This study reports on the preliminary findings for developing a new risk framework for constructing nuclear power plants. Future research is needed for advanced verification of the proposed elements. Follow-on efforts should include verification and validation of the proposed framework by industry experts and methods to quantify and evaluate the performance and risks associated with the multitude of previous NPP projects.

The design and construction of a hot dry rock pilot plant  

SciTech Connect

The geothermal energy program at the Los Alamos National Laboratory is directed toward demonstrating the potential of the hot dry rock (HDR) technology as an alternate energy source. Since the inception of the program, scientists and engineers have perfected drilling and fracturing techniques to create underground reservoirs for the purpose of tapping the potential heat energy from the hot rock in the earth. One of the achievements to date has been the creation of a reservoir at the Laboratory's test site at Fenton Hill, New Mexico. This reservoir, located at a depth of 12,000 feet below the surface of the earth, has an estimated fluid capacity of one million gallons within the large volume of fractured rock. To evaluate the thermal power potential of this reservoir, preparations are currently underway to conduct a test which will entail the circulation of fluid through the reservoir by the injection of water at high pressures. A major part of the preparations involves the building of a demonstration pilot plant. The process concept poses a number of unique technical challenges with regard to the design and construction of the equipment and facilities. This paper reviews the system design and operating features of this plant. 3 refs., 4 figs.

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".

Horizontal well construction/completion process in a Gulf of Mexico unconsolidated sand: development of baseline correlations for improved drill-in fluid cleanup practices  

E-Print Network (OSTI)

This thesis examines, in detail, the procedures and practices undertaken in the drilling and completion phases of a Gulf of Mexico horizontal well in an unconsolidated sand. In particular, this thesis presents a detailed case history analysis of well planning, completion and cleanup operations. Our objectives are to present a complete examination of the openhole horizontal well construction/completion process using a new drill-in fluid (DIF). Further, we will establish data critical to development of new cleanup correlation techniques (the continuing goal of the CEA-73 industry consortium). Project results are intended to advance the technology progression of cleanup in horizontal welts by using a "Best Completion Practices'' well to establish a baseline analysis for development of rigsite DIF cleanup correlations. Presented in this thesis are: * Completion specifics of subject well * Audit of horizontal well design/well construction process * Documentation (on-location) of lignite practices * Laboratory analyses of DO cleanup * Well performance analysis Well audit results show that prudent DIF selection requires a thorough understanding of formation and reservoir specifics, along with completion and cleanup operations. Adequate pre-planning by lignite personnel for handling, weather problems, storage/mixing requirements and fluid property maintenance are very important for successful operations using DIF. Proper maintenance of solids control systems is essential for quality control of DIF properties. Detailed well planning by the operator (Vastar Resources), coupled with a conscientious mud service company (TBC-Brinadd, Houston), led to smooth execution of well completion/cleanup operations.aboratory analyses of field DIF samples taken during drilling show that entrained drill solids in DIF can greatly impact mudcaps removal during cleanup. However, well performance was roughly three times original expectations, achieving a stabilized gas flow rate of approximately 34 MMCF/D. Horizontal well decline type curve techniques and a proprietary analysis method developed by Conoco were used to estimate formation properties, using only wellhead production rates and pressures. Using these results, we estimated DIF cupcake removal for various reservoir permeability scenarios. Results suggest that a high percentage of DIF filtercake removal was achieved only if reservoir permeability was less than the permeability range (100-500 md) initially estimated by the operator.

Improving the constructibility of the Clinch River breeder plant  

Science Conference Proceedings (OSTI)

The extended planning time which became available for Clinch River Breeder Reactor (CRBR) architect/engineers may eliminate some of the high materials and labor costs, shortages, and long lead times suffered by recent nuclear projects by allowing construction input into the planning. Since constructibility reviews are less disruptive during the conceptual design stage, a list of specific constructibility criteria has been regularly updated during the past 10 years and has solved several design problems in new technology. Several recommendations intended to save costs or make construction easier illustrate how the process developed. A scale model of the CRBR has helped to eliminate many potential construction problems in the design stage and to determine the best layout of pipe and electrical connections. Engineers can already identify over $25 million in cost avoidance on the project. (DCK)

Savannah River Plant construction [100 Area History]: Volume 3  

SciTech Connect

This report discusses five Reactor (100) Areas constructed at SRP. They were designated as 100-C, K, L, P and R. A minimum distance of two miles separated any two of the areas which were laid out in the form of a semi-circle, Each area contained approximately 40 permanent buildings and facilities for a total of 200 buildings for all of the 100 Areas. Construction was started on the R Area first and this was the first area to be completed and accepted by Operations. Construction of the other areas was started and completed in the following sequence: P, L, K and C. The difference in the design and construction of the various facilities in these areas is noted under the individual building discussion on the following pages of this section of the Construction History and also in the du Pont Engineering and Design History. In the series of manufacturing operations the separation of fissionable materials produced in the 100 Areas is accomplished by chemical and physical means in the 200 Areas These are the 200-F and 200-H Areas which have duplicate facilities in the process phase. However, a central laboratory, area shops, laundry, metallurgical and storage magazine buildings were constructed in the 200-F Area only and serve both areas. These activities are also presented in this report.

Construction of a Demand Side Plant with Thermal Energy Storage  

E-Print Network (OSTI)

Utility managements have two primary responsibilities. They must supply reliable electric service to meet the needs of their customers at the most efficient price possible while at the same time generating the maximum rate of return possible for their shareholders. Regulator hostility towards the addition of generating capacity has made it difficult for utilities to simultaneously satisfy both the needs of their ratepayers and the needs of their shareholders. Recent advances in thermal energy storage may solve the utilities' paradox. Residential thermal energy storage promises to provide the ratepayers significantly lower electricity rates and greater comfort levels. Utilities benefit from improved load factors, peak capacity additions at low cost, improved shareholder value (ie. a better return on assets), improved reliability, and a means of satisfying growing demand without the regulatory and litigious nightmares associated with current supply side solutions. This paper discusses thermal energy storage and its potential impact on the electric utilities and introduces the demand side plant concept.

Assessment of modular construction for safety-related structures at advanced nuclear power plants  

SciTech Connect

Modular construction techniques have been successfully used in a number of industries, both domestically and internationally. Recently, the use of structural modules has been proposed for advanced nuclear power plants. The objective in utilizing modular construction is to reduce the construction schedule, reduce construction costs, and improve the quality of construction. This report documents the results of a program which evaluated the proposed use of modular construction for safety-related structures in advanced nuclear power plant designs. The program included review of current modular construction technology, development of licensing review criteria for modular construction, and initial validation of currently available analytical techniques applied to concrete-filled steel structural modules. The program was conducted in three phases. The objective of the first phase was to identify the technical issues and the need for further study in order to support NRC licensing review activities. The two key findings were the need for supplementary review criteria to augment the Standard Review Plan and the need for verified design/analysis methodology for unique types of modules, such as the concrete-filled steel module. In the second phase of this program, Modular Construction Review Criteria were developed to provide guidance for licensing reviews. In the third phase, an analysis effort was conducted to determine if currently available finite element analysis techniques can be used to predict the response of concrete-filled steel modules.

Continental drilling  

DOE Green Energy (OSTI)

The Workshop on Continental Drilling was convened to prepare a report for submission to the US Geodynamics Committee with respect to the contribution that could be made by land drilling to resolve major problems of geodynamics and consider the mechanisms by which the responsibility for scientific planning, establishment of priorities, administration, and budgeting for a land-drilling program within the framework of the aims of the Geodynamics Project would best be established. A new and extensive program to study the continental crust is outlined in this report. The Workshop focused on the following topics: processes in the continental crust (mechanism of faulting and earthquakes, hydrothermal systems and active magma chambers); state and structure of the continental crust (heat flow and thermal structure of the crust; state of ambient stress in the North American plate; extent, regional structure, and evolution of crystalline continental crust); short hole investigations; present state and needs of drilling technology; drill hole experimentation and instrumentation; suggestions for organization and operation of drilling project; and suggested level of effort and funding.

Well descriptions for geothermal drilling  

DOE Green Energy (OSTI)

Generic well models have been constructed for eight major geothermal resource areas. The models define representative times and costs associated with the individual operations that can be expected during drilling and completion of geothermal wells. They were made for and have been used to evaluate the impacts of potential new technologies. Their nature, their construction, and their validation are discussed.

Environmental effects of the construction and operation of a gaseous diffusion plant  

SciTech Connect

The impacts upon the environment resulting from construction, stert-up, and operation of a gaseous dfffusion plant are described. Some of the impacts are typical regardless of location of the plant. Others are atypical and depend upon location; those are presented, by way of example, as they occur at the Portsmouth Gaseous Diffusion Plant. The various environmental contaminants that may be produced in the operating plant are described. The concentrations of those contaminants are stated; and the adverse biological effects of pertinent conteminants are elucidated. UF/sup 6/ may be enriched in the Portsmouth Gaseous Wffusion Plant to almost any /sup 235/U concentration desired. The environmental impact of the plant varies somewhat according to /sup 235/U concentrations. However, commercial plants are not expected to enrich /sup 235/U in concentrations greater than 4%. for this reason, environmental effects due to Portsmouth operations within that range are emphasized. The study revealed that present discharges from the plants generally have no detrimental effects upon the environment. (auth)

Drilling optimization using drilling simulator software  

E-Print Network (OSTI)

Drilling operations management will face hurdles to reduce costs and increase performance, and to do this with less experience and organizational drilling capacity. A technology called Drilling Simulators Software has shown an extraordinary potential to improve the drilling performance and reduce risk and cost. Different approaches have been made to develop drilling-simulator software. The Virtual Experience Simulator, geological drilling logs, and reconstructed lithology are some of the most successful. The drilling simulations can run multiple scenarios quickly and then update plans with new data to improve the results. Its storage capacity for retaining field drilling experience and knowledge add value to the program. This research shows the results of using drilling simulator software called Drilling Optimization Simulator (DROPS) in the evaluation of the Aloctono block, in the Pirital field, eastern Venezuela. This formation is characterized by very complex geology, containing faulted restructures, large dips, and hard and abrasive rocks. The drilling performance in this section has a strong impact in the profitability of the field. A number of simulations using geological drilling logs and the concept of the learning curve defined the optimum drilling parameters for the block. The result shows that DROPS has the capability to simulate the drilling performance of the area with reasonable accuracy. Thus, it is possible to predict the drilling performance using different bits and the learning-curve concept to obtain optimum drilling parameters. All of these allow a comprehensive and effective cost and drilling optimization.

Turnkey drilling  

SciTech Connect

The recent surge in the popularity of turnkey drilling has produced a number of questions about turnkey operations from both operators and contractors. The International Association of Drilling Contractors (IADC) has no approved turnkey contract (although several of the member districts have printed one), leaving the parties participating in a turnkey well unsure of their responsibilities and obligations. Additionally, operators are finding liens filed against turnkey wells they thought were paid for. The term turnkey itself is often misunderstood and applied to a variety of guaranteed well commitments. Some turnkeys require the contractor to provide everything from location preparation to final production pipe or plugs. Others allow contingencies for stuck pipe, lost circulation, kicks and bad storms.

A Plutonium Finishing Plant Model for the Cercla Removal Action and Decommissioning Construction Final Report  

Science Conference Proceedings (OSTI)

The joint policy between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) for decommissioning buildings at DOE facilities documents an agreement between the agencies to perform decommissioning activities including demolition under the Comprehensive Environmental Response Compensation and Liability Act (CERCLA). The use of removal actions for decommissioning integrates EPA oversight authority, DOE lead agency responsibility, and state authority for decommissioning activities. Once removal actions have been performed under CERCLA, a construction completion report is required to document the completion of the required action. Additionally, a decommissioning report is required under DOE guidance. No direct guidance was found for documenting completion of decommissioning activities and preparing a final report that satisfies the CERCLA requirements and the DOE requirements for decommissioning. Additional guidance was needed for the documentation of construction completion under CERCLA for D and D projects undertaken under the joint policy that addresses the requirements of both agencies. A model for the construction completion report was developed to document construction completion for CERCLA D and D activities performed under the joint EPA/DOE policy at the Plutonium Finishing Plant (PFP). The model documentation report developed at PFP integrates the DOE requirements for establishing decommissioning end-points, documenting end-point completion and preparing a final decommissioning report with the CERCLA requirements to document completion of the action identified in the Action Memorandum (AM). The model includes the required information on health and safety, data management, cost and schedule and end-points completion. (authors)

Advanced Drilling through Diagnostics-White-Drilling  

DOE Green Energy (OSTI)

A high-speed data link that would provide dramatically faster communication from downhole instruments to the surface and back again has the potential to revolutionize deep drilling for geothermal resources through Diagnostics-While-Drilling (DWD). Many aspects of the drilling process would significantly improve if downhole and surface data were acquired and processed in real-time at the surface, and used to guide the drilling operation. Such a closed-loop, driller-in-the-loop DWD system, would complete the loop between information and control, and greatly improve the performance of drilling systems. The main focus of this program is to demonstrate the value of real-time data for improving drilling. While high-rate transfer of down-hole data to the surface has been accomplished before, insufficient emphasis has been placed on utilization of the data to tune the drilling process to demonstrate the true merit of the concept. Consequently, there has been a lack of incentive on the part of industry to develop a simple, low-cost, effective high-speed data link. Demonstration of the benefits of DWD based on a high-speed data link will convince the drilling industry and stimulate the flow of private resources into the development of an economical high-speed data link for geothermal drilling applications. Such a downhole communication system would then make possible the development of surface data acquisition and expert systems that would greatly enhance drilling operations. Further, it would foster the development of downhole equipment that could be controlled from the surface to improve hole trajectory and drilling performance. Real-time data that would benefit drilling performance include: bit accelerations for use in controlling bit bounce and improving rock penetration rates and bit life; downhole fluid pressures for use in the management of drilling hydraulics and improved diagnosis of lost circulation and gas kicks; hole trajectory for use in reducing directional drilling costs; and downhole weight-on-bit and drilling torque for diagnosing drill bit performance. In general, any measurement that could shed light on the downhole environment would give us a better understanding of the drilling process and reduce drilling costs.

A Systems Engineering Framework for Design, Construction and Operation of the Next Generation Nuclear Plant  

DOE Green Energy (OSTI)

Not since the International Space Station has a project of such wide participation been proposed for the United States. Ten countries, the European Union, universities, Department of Energy (DOE) laboratories, and industry will participate in the research and development, design, construction and/or operation of the fourth generation of nuclear power plants with a demonstration reactor to be built at a DOE site and operational by the middle of the next decade. This reactor will be like no other. The Next Generation Nuclear Plant (NGNP) will be passively safe, economical, highly efficient, modular, proliferation resistant, and sustainable. In addition to electrical generation, the NGNP will demonstrate efficient and cost effective generation of hydrogen to support the Presidents Hydrogen Initiative. To effectively manage this multi-organizational and technologically complex project, systems engineering techniques and processes will be used extensively to ensure delivery of the final product. The technological and organizational challenges are complex. Research and development activities are required, material standards require development, hydrogen production, storage and infrastructure requirements are not well developed, and the Nuclear Regulatory Commission may further define risk-informed/performance-based approach to licensing. Detailed design and development will be challenged by the vast cultural and institutional differences across the participants. Systems engineering processes must bring the technological and organizational complexity together to ensure successful product delivery. This paper will define the framework for application of systems engineering to this $1.5B - $1.9B project.

Drilling for energy resources  

DOE Green Energy (OSTI)

Drilling is integral to the exploration, development, and production of most energy resources. Oil and natural gas, which are dependent on drilling technology, together account for about 77% of the energy sources consumed in the US. Thus, the limitations of current drilling technology also restrict the rate at which new energy supplies can be found, extracted, and brought to the marketplace. The purpose of the study reported was to examine current drilling technology, suggest areas where additional research and development (R and D) might significantly increase drilling rates and capabilities, and suggest a strategy for improving drilling technology. An overview is provided of the US drilling industry. The drilling equipment and techniques now used for finding and recovering oil, natural gas, coal, shale oil, nuclear fuels, and geothermal energy are described. Although by no means exhaustive, these descriptions provide the background necessary to adequately understand the problems inherent in attempts to increase instantaneous and overall drilling rates.

Navigation drilling technology progresses  

SciTech Connect

This article reports that navigation drilling - an approach that combines advanced drill bit, downhole motor, measurement-while-drilling, and well planning technology into an integrated, steerable drilling system - has reduced drilling time for operating companies worldwide. A major operating advantage of navigation drilling is the ability to drill both straight and directional intervals with a single assembly. In conventional directional drilling, a bent sub and downhole motor (or a bent housing motor) are used to initiate kick-offs and make course corrections. The bent sub is made-up above the motor, tilting the motor's axis 1 to 3 degrees compared to the axis of the drill string. The assembly toolface can be aligned in the desired direction with a single-shot, a steering tool or an MWD system.

Temperature Profile Measurements in a Newly Constructed 30-Stage 5 cm Centrifugal Contactor pilot Plant  

Science Conference Proceedings (OSTI)

An annular centrifugal contactor pilot plant incorporating 30 stages of commercial 5 cm CINC V-02 units has been built and operated at INL during the past year. The pilot plant includes an automated process control and data acquisitioning system. The primary purpose of the pilot plant is to evaluate the performance of a large number of inter-connected centrifugal contactors and obtain temperature profile measurements within a 30-stage cascade. Additional solvent extraction flowsheet testing using stable surrogates is also being considered. Preliminary hydraulic testing was conducted with all 30 contactors interconnected for continuous counter-current flow. Hydraulic performance and system operational tests were conducted successfully but with higher single-stage rotor speeds found necessary to maintain steady interstage flow at flowrates of 1 L/min and higher. Initial temperature profile measurements were also completed in this configuration studying the performance during single aqueous and two-phase counter-current flow at ambient and elevated inlet solution temperatures. Temperature profile testing of two discreet sections of the cascade required additional feed and discharge connections. Lamp oil, a commercially available alkane mixture of C14 to C18 chains, and tap water adjusted to pH 2 were the solution feeds for all the testing described in this report. Numerous temperature profiles were completed using a newly constructed 30-stage centrifugal contactor pilot plant. The automated process control and data acquisition system worked very well throughout testing. Temperature data profiles for an array of total flowrates (FT) and contactor rpm values for both single-phase and two-phase systems have been collected with selected profiles and comparisons reported. Total flowrates (FT) ranged from 0.5-1.4 L/min with rotor speeds from 3500-4000 rpm. Solution inlet temperatures ranging from ambient up to 50 C were tested. Ambient temperature testing shows that a small amount of heat is added to the processed solution by the mechanical energy of the contactors. The temperature profiles match the ambient temperature of the laboratory but are nearly 10 C higher toward the middle of the cascade. Heated input solution testing provides temperature profiles with smaller temperature gradients and are more influenced by the temperature of the inlet solutions than the ambient laboratory temperature. The temperature effects of solution mixing, even at 4000 rpm, were insignificant in any of the studies conducted on lamp oil and water.

HydroPulse Drilling  

Science Conference Proceedings (OSTI)

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.

Advanced drilling systems study  

DOE Green Energy (OSTI)

This work was initiated as part of the National Advanced Drilling and Excavation Technologies (NADET) Program. It is being performed through joint finding from the Department of Energy Geothermal Division and the Natural Gas Technology Branch, Morgantown Energy Technology Center. Interest in advanced drilling systems is high. The Geothermal Division of the Department of Energy has initiated a multi-year effort in the development of advanced drilling systems; the National Research Council completed a study of drilling and excavation technologies last year; and the MIT Energy Laboratory recently submitted a proposal for a national initiative in advanced drilling and excavation research. The primary reasons for this interest are financial. Worldwide expenditures on oil and gas drilling approach $75 billion per year. Also, drilling and well completion account for 25% to 50% of the cost of producing electricity from geothermal energy. There is incentive to search for methods to reduce the cost of drilling. Work on ideas to improve or replace rotary drilling technology dates back at least to the 1930`s. There was a significant amount of work in this area in the 1960`s and 1970`s; and there has been some continued effort through the 1980`s. Undoubtedly there are concepts for advanced drilling systems that have yet to be studied; however, it is almost certain that new efforts to initiate work on advanced drilling systems will build on an idea or a variation of an idea that has already been investigated. Therefore, a review of previous efforts coupled with a characterization of viable advanced drilling systems and the current state of technology as it applies to those systems provide the basis for the current study of advanced drilling.

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.

Remote drill bit loader  

DOE Patents (OSTI)

A drill bit loader is described for loading a tapered shank of a drill bit into a similarly tapered recess in the end of a drill spindle. The spindle has a transverse slot at the inner end of the recess. The end of the tapered shank of the drill bit has a transverse tang adapted to engage in the slot so that the drill bit will be rotated by the spindle. The loader is in the form of a cylinder adapted to receive the drill bit with the shank projecting out of the outer end of the cylinder. Retainer pins prevent rotation of the drill bit in the cylinder. The spindle is lowered to extend the shank of the drill bit into the recess in the spindle and the spindle is rotated to align the slot in the spindle with the tang on the shank. A spring unit in the cylinder is compressed by the drill bit during its entry into the recess of the spindle and resiliently drives the tang into the slot in the spindle when the tang and slot are aligned. In typical remote drilling operations, whether in hot cells or water pits, drill bits have been held using a collet or end mill type holder with set screws. In either case, to load or change a drill bit required the use master-slave manipulators to position the bits and tighten the collet or set screws. This requirement eliminated many otherwise useful work areas because they were not equipped with slaves, particularly in water pits.

Geothermal Drilling Organization  

DOE Green Energy (OSTI)

The Geothermal Drilling Organization (GDO), founded in 1982 as a joint Department of Energy (DOE)-Industry organization, develops and funds near-term technology development projects for reducing geothermal drilling costs. Sandia National Laboratories administers DOE funds to assist industry critical cost-shared projects and provides development support for each project. GDO assistance to industry is vital in developing products and procedures to lower drilling costs, in part, because the geothermal industry is small and represents a limited market.

Phased Construction of IGCC Plants for CO2 Capture - Effect of Pre-Investment  

Science Conference Proceedings (OSTI)

Currently, conceptual plant designs for integrated gasification-combined cycle (IGCC) have taken two approaches regarding the capture of CO2. Baseline plants have placed emphasis on producing power with a minimum cost and maximum efficiency without CO2 capture. The primary rationale for designing these plants without CO2 capture is that there have yet to be regulations promulgated that require the capture and sequestration of CO2. Conversely, grass roots IGCC designs with provisions for CO2 capture and c...

Managed Pressure Drilling Candidate Selection  

E-Print Network (OSTI)

Managed Pressure Drilling now at the pinnacle of the 'Oil Well Drilling' evolution tree, has itself been coined in 2003. It is an umbrella term for a few new drilling techniques and some preexisting drilling techniques, all of them aiming to solve several drilling problems, including non-productive time and/or drilling flat time issues. These techniques, now sub-classifications of Managed Pressure Drilling, are referred to as 'Variations' and 'Methods' of Managed Pressure Drilling. Although using Managed Pressure Drilling for drilling wells has several benefits, not all wells that seem a potential candidate for Managed Pressure Drilling, need Managed Pressure Drilling. The drilling industry has numerous simulators and software models to perform drilling hydraulics calculations and simulations. Most of them are designed for conventional well hydraulics, while some can perform Underbalanced Drilling calculations, and a select few can perform Managed Pressure Drilling calculations. Most of the few available Managed Pressure Drilling models are modified Underbalanced Drilling versions that fit Managed Pressure Drilling needs. However, none of them focus on Managed Pressure Drilling and its candidate selection alone. An 'Managed Pressure Drilling Candidate Selection Model and software' that can act as a preliminary screen to determine the utility of Managed Pressure Drilling for potential candidate wells are developed as a part of this research dissertation. The model and a flow diagram identify the key steps in candidate selection. The software performs the basic hydraulic calculations and provides useful results in the form of tables, plots and graphs that would help in making better engineering decisions. An additional Managed Pressure Drilling worldwide wells database with basic information on a few Managed Pressure Drilling projects has also been compiled that can act as a basic guide on the Managed Pressure Drilling variation and project frequencies and aid in Managed Pressure Drilling candidate selection.

Advanced drilling systems  

DOE Green Energy (OSTI)

Drilling is ubiquitous in oil, gas, geothermal, minerals, water well, and mining industries. Drilling and well completion account for 25% to 50% of the cost of producing power from geothermal energy. Reduced drilling costs will reduce the cost of electricity produced from geothermal resources. Undoubtedly, there are concepts for advanced drilling systems that have yet to be studied. However, the breadth and depth of previous efforts in this area almost guarantee that any new efforts will at least initially build on an idea or a variation of an idea that has already been investigated. Therefore, a review of previous efforts, coupled with a characterization of viable advanced drilling systems and the current state of technology as it applies to those systems, provide the basis for this study.

Advanced drilling systems study.  

Science Conference Proceedings (OSTI)

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.

Computers aid drilling planning  

Science Conference Proceedings (OSTI)

This article reports that computers are rapidly becoming an indispensable tool for the drilling engineer both in town and at the wellsite. Two factors have contributed to the sudden increase in their use. The first is the need to cut drilling costs. Engineers have been forced to take a more critical look at plans and past experience. The second is the falling price (and increased portability) of hardware and software. Several major operators have demonstrated that careful planning of drilling operations based on local knowledge and data from offset wells can reduce the drilling learning curve substantially. Computers make it possible to retrieve and process offset well data rapidly and efficiently. They also offer powerful mathematical models which describe complicated aspects of drilling.

Drill drive mechanism  

DOE Patents (OSTI)

A drill drive mechanism is especially adapted to provide both rotational drive and axial feed for a drill of substantial diameter such as may be used for drilling holes for roof bolts in mine shafts. The drill shaft is made with a helical pattern of scroll-like projections on its surface for removal of cuttings. The drill drive mechanism includes a plurality of sprockets carrying two chains of drive links which are arranged to interlock around the drill shaft with each drive link having depressions which mate with the scroll-like projections. As the chain links move upwardly or downwardly the surfaces of the depressions in the links mate with the scroll projections to move the shaft axially. Tangs on the drive links mate with notch surfaces between scroll projections to provide a means for rotating the shaft. Projections on the drive links mate together at the center to hold the drive links tightly around the drill shaft. The entire chain drive mechanism is rotated around the drill shaft axis by means of a hydraulic motor and gear drive to cause rotation of the drill shaft. This gear drive also connects with a differential gearset which is interconnected with a second gear. A second motor is connected to the spider shaft of the differential gearset to produce differential movement (speeds) at the output gears of the differential gearset. This differential in speed is utilized to drive said second gear at a speed different from the speed of said gear drive, this speed differential being utilized to drive said sprockets for axial movement of said drill shaft.

Witnessing the construction/commissioning of a small hydro plant as the bank's engineer  

Science Conference Proceedings (OSTI)

Many small hydro sites today are constructed as water-to-wire packages with equipment installation {und and} engineering provided by the equipment vendor. In many cases; the client has no immediate knowledge of the design/engineering associated with a hydropower facility; and is enticed by the equipment vendor to believe that the involvement of outside engineering firms is an unnecessary extra cost. Fortunately, most clients employ an outside engineering firm to confirm that the equipment the vendor is furnishing does comply with the client's equipment specifications and will function properly at this specific site. The author discusses how most banks which provide the financing for a hydro project currently hire their own hydro engineering firm to separately review the final equipment specifications, the site construction progress and the quality of construction at site. This separate review is to ensure the bank that the unit has been constructed properly and will be commissioned on time, notify the bank in a very timely manner that there are construction problems/commissioning delays, and confirm that the unit will produce its guaranteed kW output.

Comparative analysis of structural concrete quality assurance practices on three fossil fuel power plant construction projects. Final report  

SciTech Connect

The basic objective of this research effort was to perform a comparative analysis of the Quality Assurance practices related to the structural concrete phase on three fossil fuel power plant projects which are (or have been) under construction in the United States in the past ten years. This analysis identified the response of each Quality Assurance program to criteria similar to those which apply on nuclear power plant projects. The major emphasis was placed on the construction aspects of the structural concrete phase of each project. The engineering and design aspects were examined whenever they interfaced with the construction aspects. For those aspects of the Quality Assurance system which can be considered managerial in nature (i.e., organizational relationships, types of Quality Assurance programs, corrective action procedures, etc.) an attempt has been made to present the alternative approaches that were identified. For those aspects of the Quality Assurance system which are technical in nature (i.e., the frequency of testing for slump, compressive strength, etc.) an attempt has been made to present a comparative analysis between projects and in relation to the recommended or mandated practices presented in the appropriate industry codes and standards.

CONSTRUCTION DESIGN OF EBR-II: AN INTEGRATED UNMODERATED NUCLEAR POWER PLANT  

SciTech Connect

The Argoune Experimentul Breeder Reactor-II is a completely integrated nuclear power plant which employs an unmoderated reactor as a heat source, and generates 20,000 kw of electricity. The integrated nuclear plant includes the fuel re-processing and fabrication cycle and thereby makes a signigicant contribution to power reactor techaology by operating on recycled fuel. The preliminary design of this plant was described at the First International Conference on the Peaceful Uses of Atomic Energy in 1955. Although the basic design concept and objectives have remained unchanged, many modiflcations have been made in the detailed design, including separation of the facility into several plants and providing containment for the reaetor system. The plant capacity and basic power cycle have rematned essentially unchanged: 62.5 Mw thermal, 900F reactor sodium outlet temperature, and 1250-psig steam at 850F at the turbine throttle. The feed-water te mperature, however, has been increased to 550F to reduce thermal stresses in the steam generator. (auth)

Design and construction of the SMUDPV1 1-MW photovoltaic power plant. Final report I  

Science Conference Proceedings (OSTI)

The Sacramento Municipal Utility District (SMUD), with cofunding from the US Department of Energy (DOE) and the California State Energy Resources Conservation and Development Commission (CEC), designed, procured, installed, and initiated operation of a nominal 1000 kilowatt power generating facility. The facility converts solar energy directly into electricity using flat plate photovoltaic modules which are mounted on modular single-axis tracking structures. The facility is located adjacent to the Rancho Seco Nuclear Generating Station, southeast of Sacramento, California. Design work began in 1982 and the plant began operation in August 1984. Direct current power from the 112 identical tracking structures is converted to 12.5-kV alternating current power by solid state power conditioning equipment. Overall conversion efficiency, sunlight to utility grid power, is between 8 and 10%. The plant is expected to generate 2.6 million kWh annually. The capital cost of the plant was $12.14 million.

DOE Green Energy (OSTI)

Thermal spallation drilling is an underdeveloped process with great potential for reducing the costs of drilling holes and mining shafts and tunnels in most very hard rocks. Industry has used this process to drill blast holes for emplacing explosives and to quarry granite. Some theoretical work has been performed, and many signs point to a great future for this process. The Los Alamos National Laboratory has studied the theory of the spallation process and is conducting experiments to prove out the system and to adapt it for use with a conventional rotary rig. This report describes work that has been accomplished at the Laboratory on the development of thermal spallation drilling and some work that is projected for the future on the system. 3 references, 3 figures.

Laser Drilling - Drilling with the Power of Light  

Science Conference Proceedings (OSTI)

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 compares with other lasers used in past experimental work, 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. Variables investigated include laser power, beam intensity, external purging of cut materials, sample orientation, beam duration, beam shape, and beam frequency. The investigation also studied the thermal effects on the two sample rock types and their methods of destruction: spallation for sandstone, and thermal dissociation for limestone. Optimal operating conditions were identified for each rock type and condition. As a result of this experimental work, the HPFL has demonstrated a better capability of cutting and drilling limestone and sandstone when compared with other military and industrial lasers previously tested. Consideration should be given to the HPFL as the leading candidate for near term remote high power laser applications for well construction and completion.

Comparative analysis of structural concrete quality assurance practices on nine nuclear power plant construction projects. Final report  

SciTech Connect

The basic objective of this research effort was to perform a comparative analysis of the Quality Assurance practices related to the structural concrete phase on nine nuclear power plant projects which are (or have been) under construction in the United States in the past ten years. This analysis identified the response of each Quality Assurance program to the applicable criteria of 10 CFR Part 50, Appendix B as well as to the pertinent regulatory requirements and industry standards. The major emphasis was placed on the construction aspects of the structural concrete phase of each project. The engineering and design aspects were examined whenever they interfaced with the construction aspects. For those aspects of the Quality Assurance system which can be considered managerial in nature (i.e., organizational relationships, types of Quality Assurance programs, corrective action procedures, etc.) an attempt has been made to present the alternative approaches that were identified. For those aspects of the Quality Assurance system which are technical in nature (i.e., the frequency of testing for slump, compressive strength, etc.) an attempt has been made to present a comparative analysis between projects and in relation to the recommended or mandated practices presented in the appropriate industry codes and standards.

Proper planning improves flow drilling  

Science Conference Proceedings (OSTI)

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.

SciTech Connect

An improved mechanical drill string jar is described that allows uninhibited telescoping movement to the normal drilling condition. The drill string jar consists of: (a) an elongated, generally cylindrical, body usable as a drill string element; (b) axial motion resistance means situated in the annular opening; (c) bias means operatively associated with at least one element of the splined pair to rotate the pair out of alignment when the splined pair is rotationally disengaged; (d) opposed cooperating surfaces on at least two of the spline teeth situated such that forced axial relative motion of the splined pair will produce opposed radial forces on the teeth; (e) means intrinsic to at least one element of the splined pair to permit resisted radial displacement of the spline teeth when forced axial relative motion occurs, to permit one element to move axially through the other; (f) cam surfaces on at least one of the teeth situated to force rotational alignment of the splined pair when telescoping movement is from a jarring condition toward the normal drilling condition; (g) relative rotation resistance means situated in the annular opening, structurally engaged with the pair of telescoping members such that relative rotation therebetween will be resisted; (h) striker and anvil means situated in the annular opening, operatively associated with the telescoping pair of elements, such that axial relative movement therebetween will be solidly stopped at the axial extreme condition; (i) a flow-through fluid channel means extending between the means to attach to the continuing drill string; and (j) seal means situated in the annular opening, operatively associated with the telescoping pair of members, to provide fluid tightness therebetween.

Critique of Drilling Research  

SciTech Connect

For a number of years the Department of Energy has been funding research to reduce the cost of drilling geothermal wells. Generally that research has been effective and helped to make geothermal energy economically attractive to developers. With the increased competition for the electrical market, geothermal energy needs every advantage it can acquire to allow it to continue as a viable force in the marketplace. In drilling related research, there is essentially continuous dialogue between industry and the national laboratories. Therefore, the projects presented in the Program Review are focused on subjects that were previously recommended or approved by industry.

Deepwater drilling riser system  

Science Conference Proceedings (OSTI)

The principal focus of this paper is to discuss and summarize, from the manufacturer's perspective, the primary milestones in the development of the marine riser system used to drill in record water depths off the U.S. east coast. This riser system is unique in that it used advanced designs, material technology, and quality control to enable safe operation in water depths beyond the capability of conventional drilling riser systems. Experience and research have led to design improvements that are now being incorporated in new riser systems that have the potential of expanding the frontiers to increasingly deeper water.

Combination drilling and skiving tool  

DOE Patents (OSTI)

A combination drilling and skiving tool including a longitudinally extending hollow skiving sleeve slidably and concentrically mounted on a right-handed twist drill. Dogs or pawls provided on the internal periphery of the skiving sleeve engage with the helical grooves of the drill. During a clockwise rotation of the tool, the drill moves downwardly and the sleeve translates upwardly, so that the drill performs a drilling operation on a workpiece. On the other hand, the drill moves upwardly and the sleeve translates downwardly, when the tool is rotated in a counter-clockwise direction, and the sleeve performs a skiving operation. The drilling and skiving operations are separate, independent and exclusive of each other.

Foam drilling simulator  

E-Print Network (OSTI)

Although the use of compressible drilling fluids is experiencing growth, the flow behavior and stability properties of drilling foams are more complicated than those of conventional fluids. In contrast with conventional mud, the physical properties of foam change along the wellbore. Foam physical and thermal properties are strongly affected by pressure and temperature. Many problems associated with field applications still exist, and a precise characterization of the rheological properties of these complex systems needs to be performed. The accurate determination of the foam properties in circulating wells helps to achieve better estimation of foam rheology and pressure. A computer code is developed to process the data and closely simulate the pressure during drilling a well. The model also offers a detailed discussion of many aspects of foam drilling operations and enables the user to generate many comparative graphs and tables. The effects of some important parameters such as: back-pressure, rate of penetration, cuttings concentration, cuttings size, and formation water influx on pressure, injection rate, and velocity are presented in tabular and graphical form. A discretized heat transfer model is formulated with an energy balance on a control volume in the flowing fluid. The finite difference model (FDM) is used to write the governing heat transfer equations in discretized form. A detailed discussion on the determination of heat transfer coefficients and the solution approach is presented. Additional research is required to analyze the foam heat transfer coefficient and thermal conductivity.

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.

Drill bit assembly for releasably retaining a drill bit cutter  

DOE Patents (OSTI)

A drill bit assembly is provided for releasably retaining a polycrystalline diamond compact drill bit cutter. Two adjacent cavities formed in a drill bit body house, respectively, the disc-shaped drill bit cutter and a wedge-shaped cutter lock element with a removable fastener. The cutter lock element engages one flat surface of the cutter to retain the cutter in its cavity. The drill bit assembly thus enables the cutter to be locked against axial and/or rotational movement while still providing for easy removal of a worn or damaged cutter. The ability to adjust and replace cutters in the field reduces the effect of wear, helps maintains performance and improves drilling efficiency.

Laser Drilling - Drilling with the Power of Light  

Science Conference Proceedings (OSTI)

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.

High speed drilling research advances  

Science Conference Proceedings (OSTI)

This article reports that the Amoco Production Company's Tulsa Research Center is developing a High Speed Drilling System (HSDS) to improve drilling economics for both exploration and development wells. The system is targeted for areas where historically the drilling rate is less than 25 ft/hr over a large section of hole. Designed as a five-year development program, work began on the system in late 1984. A major service company is participating in the project. The objective of the HSDS project is to improve drilling efficiency by developing improvements in the basic mechanical drilling system. The HSDS approach to improved drilling economics is via the traditional routes of increasing penetration rate (ROP) and bit life, increasing hole stability and reducing trouble time.

Drill string gas data  

DOE Green Energy (OSTI)

Data and supporting documentation were compiled and analyzed for 26 cases of gas grab samples taken during waste-tank core sampling activities between September 1, 1995 and December 31, 1997. These cases were tested against specific criteria to reduce uncertainties associated with in-tank sampling location and conditions. Of the 26 possible cases, 16 qualified as drill-string grab samples most likely to represent recently released waste gases. The data from these 16 ``confirmed`` cases were adjusted to remove non-waste gas contributions from core-sampling activities (argon or nitrogen purge), the atmospheric background, and laboratory sampler preparation (helium). The procedure for subtracting atmospheric, laboratory, and argon purge gases was unambiguous. No reliable method for determining the exact amount of nitrogen purge gas was established. Thus, the final set of ``Adjusted`` drill string gas data for the 6 nitrogen-purged cases had a greater degree of uncertainty than the final results for the 10 argon-purged cases. Including the appropriate amounts of uncertainty, this final set of data was added to the set of high-quality results from the Retained Gas Sampler (RGS), and good agreement was found for the N{sub 2}, H{sub 2}, and N{sub 2}O mole fractions sampled from common tanks. These results indicate that under favorable sampling conditions, Drill-String (DS) grab samples can provide reasonably accurate information about the dominant species of released gas. One conclusion from this set of total gas data is that the distribution of the H{sub 2} mole fractions is bimodal in shape, with an upper bound of 78%.

Underbalanced drilling solves difficult drilling problems and enhances production  

Science Conference Proceedings (OSTI)

An alternate approach to drilling, completing and working over new and existing wells has dramatically improved the efficiency of these operations. This method is called underbalanced drilling (UBD). Improvements in both the equipment and technique during the past 5 years have made this process economical and necessary to solve many difficult drilling problems. Additionally, by reducing drilling or workover damage, dramatic improvements in oil and gas production rates and ultimate reserves are realized, resulting in extra profits for today`s operators. This article will detail the advantages of UBD and give specific examples of its applications, A series of related articles will follow, including: new UBD equipment, land and off-shore case histories, coiled tubing drilling, underbalanced workovers, software technology and subsea applications to examine the reality and future of this technology.

Rig scarcity prompts innovative drilling solution  

Science Conference Proceedings (OSTI)

Unable to locate a shallow-water offshore rig for its program in Indonesia, British Gas International developed an innovative pad/ballasted barge configuration to utilize a land rig, which was available. Many non-typical problems were encountered and solved to establish the drilling location 600 m (2,000 ft) from the shore in Bintuni Bay in Irian Jaya, eastern Indonesia. The final hybrid configuration has sparked interesting debate as to whether the operation should be designated as onshore or offshore. The paper discusses the project overview, concept development, construction, and operations.

Comparative analysis of structural concrete Quality Assurance practices on nine nuclear and three fossil fuel power plant construction projects. Final summary report  

SciTech Connect

A summary of two reports, COO/4120-1 and COO/4120-2, is given. A comparative analysis was made of the Quality Assurance practices related to the structural concrete phase on nine nuclear and three fossil fuel power plant projects which are (or have been) under construction in the United States in the past ten years. For the nuclear projects the analysis identified the response of each Quality Assurance program to the applicable criteria of 10 CFR Part 50, Appendix B as well as to the pertinent regulatory requirements and industry standards. For the fossil projects the analysis identified the response of each Quality Assurance program to criteria similar to those which were applicable in the nuclear situation. The major emphasis was placed on the construction aspects of the structural concrete phase of each project. The engineering and design aspects were examined whenever they interfaced with the construction aspects.

Establishing nuclear facility drill programs  

SciTech Connect

The purpose of DOE Handbook, Establishing Nuclear Facility Drill Programs, is to provide DOE contractor organizations with guidance for development or modification of drill programs that both train on and evaluate facility training and procedures dealing with a variety of abnormal and emergency operating situations likely to occur at a facility. The handbook focuses on conducting drills as part of a training and qualification program (typically within a single facility), and is not intended to included responses of personnel beyond the site boundary, e.g. Local or State Emergency Management, Law Enforcement, etc. Each facility is expected to develop its own facility specific scenarios, and should not limit them to equipment failures but should include personnel injuries and other likely events. A well-developed and consistently administered drill program can effectively provide training and evaluation of facility operating personnel in controlling abnormal and emergency operating situations. To ensure the drills are meeting their intended purpose they should have evaluation criteria for evaluating the knowledge and skills of the facility operating personnel. Training and evaluation of staff skills and knowledge such as component and system interrelationship, reasoning and judgment, team interactions, and communications can be accomplished with drills. The appendices to this Handbook contain both models and additional guidance for establishing drill programs at the Department`s nuclear facilities.

Drainhole drilling projects under way  

Science Conference Proceedings (OSTI)

This paper reports that many operators are taking advantage of continued developments in drainhole drilling technology to increase productivity in certain fields. Previously untapped prospects are under renewed scrutiny to determine if drainhole and horizontal drilling can make them more attractive. Producing properties are being reevaluated as well. Drainhole drilling typically involves reentering an existing well and cutting through the casing to drill a relatively short length of horizontal wellbore. Although separating drainhole and horizonal or extended-reach drilling is somewhat of a gray area, one difference is that a drainhole well turns to the horizontal much quicker. The radius of turn to 90/sup 0/ can be as little as 30 to 50 ft. Additionally, the length of horizontal kick in a drainhole well is typically in the 300- to 500-ft range compared to 1000 ft or more in extended-reach drilling. A final separating characteristic is that drainhole drilling can be associated with several horizontal lengths of wellbore coming off a single vertical hole.

Acoustical properties of drill strings  

DOE Green Energy (OSTI)

The recovery of petrochemical and geothermal resources requires extensive drilling of wells to increasingly greater depths. Real-time collection and telemetry of data about the drilling process while it occurs thousands of feet below the surface is an effective way of improving the efficiency of drilling operations. Unfortunately, due to hostile down-hole environments, telemetry of this data is an extremely difficult problem. Currently, commercial systems transmit data to the surface by producing pressure pulses within the portion of the drilling mud enclosed in the hollow steel drill string. Transmission rates are between two and four data bits per second. Any system capable of raising data rates without increasing the complexity of the drilling process will have significant economic impact. One alternative system is based upon acoustical carrier waves generated within the drill string itself. If developed, this method would accommodate data rates up to 100 bits per second. Unfortunately, the drill string is a periodic structure of pipe and threaded tool joints, the transmission characteristics are very complex and exhibit a banded and dispersive structure. Over the past forty years, attempts to field systems based upon this transmission method have resulted in little success. This paper examines this acoustical transmission problem in great detail. The basic principles of acoustic wave propagation in the periodic structure of the drill string are examined through theory, laboratory experiment, and field test. The results indicate the existence of frequency bands which are virtually free of attenuation and suitable for data transmission at high bit rates. 9 refs., 38 figs., 2 tabs.

Slurry Injection Slurry Injection Fact Sheet - Slurry Injection of Drilling Wastes Underground Injection of Drilling Wastes Several different approaches are used for injecting drilling wastes into underground formations for permanent disposal. Salt caverns are described in a separate fact sheet. This fact sheet focuses on slurry injection technology, which involves grinding or processing solids into small particles, mixing them with water or some other liquid to make a slurry, and injecting the slurry into an underground formation at pressures high enough to fracture the rock. The process referred to here as slurry injection has been given other designations by different authors, including slurry fracture injection (this descriptive term is copyrighted by a company that provides slurry injection services), fracture slurry injection, drilled cuttings injection, cuttings reinjection, and grind and inject.

Laser Drilling - Drilling with the Power of Light  

Science Conference Proceedings (OSTI)

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.

Infill drilling enhances waterflood recovery  

Science Conference Proceedings (OSTI)

Two sets of west Texas carbonate reservoir and waterflood data were studied to evaluate the impact of infill drilling on waterflood recovery. Results show that infill drilling enhanced the current and projected waterflood recovery from most of the reservoirs. The estimated ultimate and incremental infill-drilling waterflood recovery was correlated with well spacing and other reservoir and process parameters. Results of the correlation indicate that reducing well spacing from 40 to 20 acres (16 to 8 ha) per well would increase the oil recovery by 8 to 9% of the original oil in place (OOIP). Because of the limited data base and regressional nature of the correlation models, the infill-drilling recovery estimate must be used with caution.

Restored Drill Cuttings for Wetlands Creation: Results of Mesocosm Approach to Emulate Field Conditions Under Varying Salinity and Hydrologic Conditions  

Science Conference Proceedings (OSTI)

Both interstitial water and plant tissue associated with the DC-A substrate exhibited low metal concentrations. Also in agreement with the previous study, plant performance in the DC-A substrate was found to be comparable to plant performance in the dredge spoil and topsoil substrates. This was extremely important because it indicated that the drill cuttings themselves served as an excellent substrate for wetland plant growth, but that the processing and stabilization techniques and drilling fluid formulations required further refinement.

PAO lubricant inhibits bit balling, speeds drilling  

Science Conference Proceedings (OSTI)

For drilling operations, a new polyalphaolefin (PAO) lubricant improves penetration rates by reducing bit balling tendencies in water-based mud. The additive also reduces drillstring drag. This enables the effective transmission of weight to the bit and thereby increases drilling efficiency in such applications as directional and horizontal drilling. The paper describes drilling advances, bit balling, laboratory testing, and test analysis.

DOE/EA-1517: Environmental Assessment for the Design and Construction of a Fuel Ethanol Plant, Jasper County, Indiana (April 2005)  

DOE Green Energy (OSTI)

Based on action by the U.S. Congress, the U.S. Department of Energy (DOE) has funding available to support a proposal by the Iroquois Bio-energy Company (IBEC), an Indiana limited liability company, to construct a fuel ethanol plant in Jasper County, Indiana (the proposed plant). Congress has acknowledged the merit of this project by providing specific funding through DOE. Consequently, DOE proposes to provide partial funding to IBEC to subsidize the design and construction of the proposed plant (the Proposed Action). In accordance with DOE and National Environmental Policy Act (NEPA) implementing regulations, DOE is required to evaluate the potential environmental impacts of DOE facilities, operations, and related funding decisions. The proposal to use Federal funds to support the project requires DOE to address NEPA requirements and related environmental documentation and permitting requirements. In compliance with NEPA (42 U.S.C. {section} 4321 et seq.) and DOE's NEPA implementing regulations (10 CFR section 1021.330) and procedures, this environmental assessment (EA) examines the potential environmental impacts of DOE's Proposed Action and a No Action Alternative.

Chemical damage due to drilling operations  

DOE Green Energy (OSTI)

The drilling of geothermal wells can result in near wellbore damage of both the injection wells and production wells if proper precautions are not taken. Very little specific information on the chemical causes for drilling damage that can directly be applied to the drilling of a geothermal well in a given situation is available in the literature. As part of the present work, the sparse literature references related to the chemical aspects of drilling damage are reviewed. The various sources of chemically induced drilling damages that are related to drilling operations are summarized. Various means of minimizing these chemical damages during and after the drilling of a geothermal well are suggested also.

Managed pressure drilling techniques and tools  

E-Print Network (OSTI)

The economics of drilling offshore wells is important as we drill more wells in deeper water. Drilling-related problems, including stuck pipe, lost circulation, and excessive mud cost, show the need for better drilling technology. If we can solve these problems, the economics of drilling the wells will improve, thus enabling the industry to drill wells that were previously uneconomical. Managed pressure drilling (MPD) is a new technology that enables a driller to more precisely control annular pressures in the wellbore to prevent these drillingrelated problems. This paper traces the history of MPD, showing how different techniques can reduce drilling problems. MPD improves the economics of drilling wells by reducing drilling problems. Further economic studies are necessary to determine exactly how much cost savings MPD can provide in certain situation. Furter research is also necessary on the various MPD techniques to increase their effectiveness.

Downhole Temperature Prediction for Drilling Geothermal Wells  

DOE Green Energy (OSTI)

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.

The sequence coding and search system: An approach for constructing and analyzing event sequences at commercial nuclear power plants  

SciTech Connect

The US Nuclear Regulatory Commission (NRC) has recognized the importance of the collection, assessment, and feedstock of operating experience data from commercial nuclear power plants and has centralized these activities in the Office for Analysis and Evaluation of Operational Data (AEOD). Such data is essential for performing safety and reliability analyses, especially analyses of trends and patterns to identify undesirable changes in plant performance at the earliest opportunity to implement corrective measures to preclude the occurrences of a more serious event. One of NRC's principal tools for collecting and evaluating operating experience data is the Sequence Coding and Search System (SCSS). The SCSS consists of a methodology for structuring event sequences and the requisite computer system to store and search the data. The source information for SCSS is the Licensee Event Report (LER), which is a legally required document. This paper describes the objective SCSS, the information it contains, and the format and approach for constructuring SCSS event sequences. Examples are presented demonstrating the use SCSS to support the analysis of LER data. The SCSS contains over 30,000 LERs describing events from 1980 through the present. Insights gained from working with a complex data system from the initial developmental stage to the point of a mature operating system are highlighted.

Definition: Drilling Techniques | Open Energy Information  

Open Energy Info (EERE)

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.

Underbalanced drilling: Praises and perils  

Science Conference Proceedings (OSTI)

Underbalanced drilling (UBD) has been used with increasing frequency to minimize problems associated with invasive formation damage, which often greatly reduce the productivity of oil and gas reservoirs, particularly in openhole horizontal well applications. UBD, when properly designed and executed, minimizes or eliminates problems associated with the invasion of particulate matter into the formation as well as a multitude of other problems such as adverse clay reactions, phase trapping, precipitation, and emulsification, which can be caused by the invasion of incompatible mud filtrates in an overbalanced condition. In many UBD operations, additional benefits are seen because of a reduction in drilling time, greater rates of penetration, increased bit life, a rapid indication of productive reservoir zones, and the potential for dynamic flow testing while drilling. Potential downsides and damage mechanisms associated with UBD will be discussed. These include the following: (1) Increased cost and safety concerns; (2) Difficulty in maintaining a continuously underbalanced condition; (3) Spontaneous inhibition and countercurrent inhibition effects; (4) Glazing, mashing, and mechanically induced wellbore damage; (5) Macroporosity gravity-induced invasion; (6) Difficulty of application in zones of extreme pressure and permeability; and (7) Political/career risk associated with championing a new and potentially risky technology. The authors discuss reservoir parameters required to design an effective underbalanced or overbalanced drilling program, laboratory screening procedures to ascertain the effectiveness of UBD in a specific application and review the types of reservoirs that often present good applications for UBD technology.

Borehole Summary Report for Waste Treatment Plant Seismic Borehole C4993  

SciTech Connect

A core hole (C4998) and three boreholes (C4993, C4996, and C4997) were drilled to acquire stratigraphic and downhole seismic data to model potential seismic impacts and to refine design specifications and seismic criteria for the Waste Treatment Plant (WTP) under construction on the Hanford Site. Borehole C4993 was completed through the Saddle Mountains Basalt, the upper portion of the Wanapum Basalt, and associated sedimentary interbeds, to provide a continuous record of the rock penetrated by all four holes and to provide access to the subsurface for geophysical measurement. Presented and compiled in this report are field-generated records for the deep mud rotary borehole C4993 at the WTP site. Material for C4993 includes borehole logs, lithologic summary, and record of rock chip samples collected during drilling through the months of August through early October. The borehole summary report also includes documentation of the mud rotary drilling, borehole logging, and sample collection.

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

Downhole mud properties complicate drilling hydraulics  

Science Conference Proceedings (OSTI)

This paper explains that wellsite parameters such as penetration rate, hole cleaning, hole erosion and overall wellbore stability are directly related to the hydraulic conditions occurring while drilling. Drilling hydraulics, in turn, are largely a function of the drilling mud's properties, primarily viscosity and density. Accurate pressure loss calculations are necessary to maximize bit horse-power and penetration rates. Also, annular pressure loss measurements are important to record equivalent circulating densities, particularly when drilling near balanced formation pressures or when approaching formation fracture pressures. Determination of the laminar, transitional or turbulent flow regimes will help ensure the mud will remove drill cuttings from the wellbore and minimize hole erosion.

Innovative techniques cut costs in wetlands drilling  

Science Conference Proceedings (OSTI)

This paper reports on an approach to drilling oil and gas wells in sensitive wetlands areas contributed to a savings of over $1.2 million on a three-well, $3 million drilling project in south Louisiana. ARCO Oil and Gas Co. drilled a three-well project in the Bayou Sale field with a truck-mounted workover rig and a modified solids-control system. This smaller equipment eliminated the need to build a large location in the marsh. Traditional drilling techniques require a large drillsite to accommodate all the equipment of a modern drilling complex. However, recently imposed environmental regulations substantially limit, and in some cases prohibit, the use of these conventional techniques for drilling wells in wetlands areas. Based on the potentially huge economic and operational impact on the drilling industry because of these stricter regulations, alternatives to these traditional practices are essential.

Underbalanced drilling with air offers many pluses  

Science Conference Proceedings (OSTI)

A pressure overbalance during conventional drilling can cause significant fluid filtrate invasion and lost circulation. Fluid invasion into the formation can lead to formation damage, high mud costs, a need for expensive completions, and well productivity impairment. Because underbalanced drilling creates a natural tendency for fluid and gas to flow from the formation to the borehole, successful underbalanced drilling depends upon the appropriate selection of circulating fluid. The use of a compressible fluid in the circulating system, referred to as air drilling, lowers the downhole pressure, allowing drilling into and beyond these sensitive formations. The paper discusses the equipment needed; well control; downhole air requirements; air drilling techniques using dry air, air-mist, stable foam, stiff foam, and aerated-fluid; downhole fires; directional air drilling; and well completions.

Chemical Speciation of Chromium in Drilling Muds  

Science Conference Proceedings (OSTI)

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.

Slant rigs offer big payoffs in shallow drilling  

Science Conference Proceedings (OSTI)

Slant hole drilling technology can result in considerable savings over conventionally drilled deviated holes because mud motors and deviation control with measurement while drilling tools are usually unnecessary. The benefits of using slant hole rigs for development drilling improve after the bit walk tendencies and the correct bottom hole assemblies have been determined for a particular area. This article discusses three recent drilling operations that successfully used slant drilling technology on land-based projects: drilling for heavy oil in Alberta, drilling for gas in Alberta, and drilling a river crossing for a gas pipeline in British Columbia. These examples demonstrate the flexibility of slant drilling technology.

Underbalanced drilling guidelines improve safety, efficiency  

Science Conference Proceedings (OSTI)

In underbalanced drilling, the primary means of well control, the hydrostatic head of the drilling fluid, is lost either unavoidably because of hole problems (such as abnormally high pressure or lost circulation) or intentionally because of economics or to prevent formation damage. Because of complications with underbalanced drilling, however, several rigs have been destroyed by fire. Operational guidelines are being developed in close cooperation with industry. The final guidelines will be consistent with the existing standards of well control practices in Alberta, yet applicable for underbalanced drilling operations world-wide. Until formal guidelines are completed in Alberta, operators interested in underbalanced drilling should work closely with the Energy Resources Conservation Board in preparing site-specific programs. Although underbalanced drilling is often associated with horizontal wells, the majority of underbalanced drilling operations in Alberta are conducted on vertical wells. The paper describes underbalanced drilling, blowout prevention, surface BOP equipment (stripper, annular pack off, rotating head, rotating BOP, coiled tubing), subsurface BOP, drilling fluids, nitrified drilling fluids, surface equipment, well-site supervision, well control equipment, and the surface handling of fluids.

Casing pull tests for directionally drilled environmental wells  

SciTech Connect

A series of tests to evaluate several types of environmental well casings have been conducted by Sandia National Laboratories (SNL) and it`s industrial partner, The Charles Machine Works, Inc. (CMW). A test bed was constructed at the CMW test range to model a typical shallow, horizontal, directionally drilled wellbore. Four different types of casings were pulled through this test bed. The loads required to pull the casings through the test bed and the condition of the casing material were documented during the pulling operations. An additional test was conducted to make a comparison of test bed vs actual wellbore casing pull loads. A directionally drilled well was emplaced by CMW to closely match the test bed.

Reservoir screening criteria for underbalanced drilling  

Science Conference Proceedings (OSTI)

Properly designed and executed underbalanced drilling operations can eliminate or significantly reduce formation damage, mud or drill solids invasion, lost circulation, fluid entrainment and trapping effects, and potential adverse reactions of drilling fluids with the reservoir matrix or in-situ reservoir fluids. The key to selecting appropriate reservoir candidates is achieving a balance of technical, safety and economic factors. Not every reservoir is an ideal candidate for an underbalanced drilling operation and in some cases distinct disadvantages may exist in trying to execute an underbalanced drilling operation in comparison to a simpler more conventional overbalanced application. Extensive field experience has played an important role in determining the following key criteria and design considerations that should be examined when evaluating a well. Screening criteria are also provided to help operators ascertain if a given formation is, in fact, a viable underbalanced drilling candidate.

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

Vale exploratory slimhole: Drilling and testing  

SciTech Connect

During April-May, 1995, Sandia National Laboratories, in cooperation with Trans-Pacific Geothermal Corporation, drilled a 5825{prime} exploratory slimhole (3.85 in. diameter) in the Vale Known Geothermal Resource Area (KGRA) near Vale, Oregon. This well was part of Sandia`s program to evaluate slimholes as a geothermal exploration tool. During drilling we performed several temperature logs, and after drilling was complete we performed injection tests, bailing from a zone isolated by a packer, and repeated temperature logs. In addition to these measurements, the well`s data set includes: 2714{prime} of continuous core (with detailed log); daily drilling reports from Sandia and from drilling contractor personnel; daily drilling fluid records; numerous temperature logs; pressure shut-in data from injection tests; and comparative data from other wells drilled in the Vale KGRA. This report contains: (1) a narrative account of the drilling and testing, (2) a description of equipment used, (3) a brief geologic description of the formation drilled, (4) a summary and preliminary interpretation of the data, and (5) recommendations for future work.

Strong growth projected for underbalanced drilling  

Science Conference Proceedings (OSTI)

The use of underbalanced drilling technology should grow steadily during the next decade. The projected growth is primarily driven by increased concern about formation damage, the potential for higher penetration rates, and the ability to reduce lost circulation in depleted reservoirs. The Department of Energy`s Morgantown Energy Technology Center manages a portfolio of drilling-related research, development, and demonstration (RD and D) projects designed to reduce costs and improve efficiencies. The Department of Energy sponsored Maurer Engineering Inc. (MEI) to develop a user-friendly foam drilling model that can accurately predict pressure drops, cuttings lifting velocities, foam quality, and other foam drilling variables. A second objective of the project was to develop a light-weight drilling fluid that would allow underbalanced drilling in low-pressure reservoirs without the limitations commonly associated with existing light-weight fluids. Maurer performed a study to gauge the potential for light-weight drilling fluids and the extent of underbalanced drilling activity in the US. Data from many industry sources, including recent publications on the potential for air drilling, were evaluated and incorporated into this study. This paper discusses the findings from this survey.

NETL Extreme Drilling Laboratory Studies High Pressure High Temperature Drilling Phenomena

This paper details the challenges of ultra-deep drilling, documents reports of decreased drilling rates as a result of increasing fluid pressure and temperature, and describes NETLs Research and Development activities. NETL is invested in laboratory-scale physical simulation. Their physical simulator will have capability of circulating drilling fluids at 30,000 psi and 480 F around a single drill cutter. This simulator will not yet be operational by the planned conference dates; therefore, the results will be limited to identification of leading hypotheses of drilling phenomena and NETLs test plans to validate or refute such theories. Of particular interest to the Extreme Drilling Labs studies are the combinatorial effects of drilling fluid pressure, drilling fluid properties, rock properties, pore pressure, and drilling parameters, such as cutter rotational speed, weight on bit, and hydraulics associated with drilling fluid introduction to the rock-cutter interface. A detailed discussion of how each variable is controlled in a laboratory setting will be part of the conference paper and presentation.

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.

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.

Measurement-While-Drilling (MWD) development for air drilling  

Science Conference Proceedings (OSTI)

When downhole contact between the BHA and formation was optimum, as it was during rotation, high signal levels were experienced. Survey data acquired at the connections, when the BHA was totally at rest, is excellent. GEC intends modifying the system to optimize operations consistent with these disparate factors. A Mean-Time-To-Failure (MTTF) of 89.9 hours appears reasonable from the data. It is not possible to infer an MTBF figure from this test. It is quite obvious, however, that the system reliability performance has been significantly improved since FT {number_sign}5 was performed almost two years earlier. Based on the above results, GEC concludes that it is certainly feasible to attain 100 hours MTBF, for the Model 27, in any and all situations, and hence to provide a reliable MWD for air-drilling.

Drilling fluid effects on crop growth and iron and zinc availability  

Science Conference Proceedings (OSTI)

Waste drilling fluids are often land-farmed following completion of an oil or gas well in Colorado. This material usually contains production water, bentonitic clays, formation cuttings, barite, Na compounds, and synthetic organic polymers. The authors investigated the effects of 5 to 60 dry g drilling fluid kg{sup {minus}1} soil on the growth and trace metal concentration of sorghum-sudangrass (Sorghum bicolor L. Moench DeKalb ST-6-S sudanense) in the greenhouse. A nonlinear regression exponential-rise model fit the increased plant total dry matter yield response to increasing drilling fluid rates. Increased plant tissue Fe concentration and uptake indicated that increased plant-available Fe was primarily responsible for the yield response, but increased Zn availability was also suspected. Results from a second greenhouse study confirmed that drilling fluid can also correct Zn deficiency in corn (Zea mays L.). Soil SAR (sodium adsorption ratio) was higher with increasing drilling fluid, but was still sorghum-sudangrass and provided evidence that land application is an acceptable method of disposal.

The pipe line route closely parallels a 4-mi ROW section of Houston Power and Light Co. (HP and L) and about 4 mi of Union Pacific Railroad tracks. Due to overhead towers carrying high-voltage electric transmission lines, Great Plains bored under the existing towers in HP and L's easement to preserve the right of way for future tower expansion. Laney, Inc., subcontracted the conventional bores underneath towers and minor roads. Laney Directional Drilling Co. was the prime contractor for two horizontal directionally drilled crossings of the Houston Ship Channel and Carpenter's Bayou. Great Plains, with its own crew, completed three roadway crossings in high-traffic areas. Engineering and material procurement was handled by APLC.

Balanced pressure techniques applied to geothermal drilling  

DOE Green Energy (OSTI)

The objective of the study is to evaluate balanced pressure drilling techniques for use in combating lost circulation in geothermal drilling. Drilling techniques evaluated are: aerated drilling mud, parasite tubing, concentric drill pipe, jet sub, and low density fluids. Based on the present state of the art of balanced pressure drilling techniques, drilling with aerated water has the best overall balance of performance, risk, availability, and cost. Aerated water with a 19:1 free air/water ratio reduce maximum pressure unbalance between wellbore and formation pressures from 1000 psi to 50 psi. This pressure unbalance is within acceptable operating limits; however, air pockets could form and cause pressure surges in the mud system due to high percent of air. Low density fluids used with parasite tubing has the greatest potential for combating lost circulation in geothermal drilling, when performance only is considered. The top portion of the hole would be aerated through the parasite tube at a 10:1 free air/mud ratio and the low density mud could be designed so that its pressure gradient exactly matches the formation pore pressure gradient. The main problem with this system at present is the high cost of ceramic beads needed to produce low density muds.

Geothermal drilling and completion technology development  

SciTech Connect

The high cost of drilling and completing geothermal wells is an impediment to the development of geothermal energy resources. Technological deficiencies in rotary drilling techniques are evidenced when drilling geothermal wells. The Division of Geothermal Energy (DGE) of the U.S. Department of Energy has initiated a program aimed at developing new drilling and completion techniques for geothermal wells. The goals of this program are to reduce well costs by 25% by 1982 and by 50% by 1986. Sandia Laboratories has been selected to manage this technology development program, and this paper presents an overview of the program. Program justification which relates well cost to busbar energy cost and to DGE power-on-line goals is presented. Technological deficiencies in current rotary drilling techniques for geothermal wells are discussed. A program for correcting these deficiencies is described.

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.

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.

Steamboat Hills exploratory slimhole: Drilling and testing  

DOE Green Energy (OSTI)

During July-September, 1993, Sandia National Laboratories, in cooperation with Far West Capital, drilled a 4000 feet exploratory slimhole (3.9 inch diameter) in the Steamboat Hills geothermal field near Reno, Nevada. This well was part of Sandia`s program to evaluate slimholes as a geothermal exploration tool. During and after drilling the authors performed four series of production and injection tests while taking downhole (pressure-temperature-spinner) and surface (wellhead pressure and temperature, flow rate) data. In addition to these measurements, the well`s data set includes: continuous core (with detailed log); borehole televiewer images of the wellbore`s upper 500 feet; daily drilling reports from Sandia and from drilling contractor personnel; daily drilling fluid record; numerous temperature logs; and comparative data from production and injection wells in the same field. This report contains: (1) a narrative account of the drilling and testing, (2) a description of equipment used, (3) a brief geologic description of the formation drilled, (4) a summary and preliminary interpretation of the data, and (5) recommendations for future work.

Development and testing of underbalanced drilling products  

Science Conference Proceedings (OSTI)

The first objective of this project is to develop a user-friendly, PC, foam drilling computer model, FOAM, which will accurately predict frictional pressure drops, cuttings lifting velocity, foam quality, and other drilling variables. The model will allow operating and service companies to accurately predict pressures and flow rates required at the surface and downhole to efficiently drill oil and gas wells with foam systems. The second objective of this project is to develop a lightweight drilling fluid that utilizes hollow glass spheres to reduce the density of the fluid and allow drilling underbalanced in low-pressure reservoirs. Since the resulting fluid will be incompressible, hydraulics calculations are greatly simplified, and expensive air compressors and booster pumps are eliminated. This lightweight fluid will also eliminate corrosion and downhole fire problems encountered with aerated fluids. Many tight-gas reservoirs in the US are attractive targets for underbalanced drilling because they are located in hard-rock country where tight, low-permeability formations compound the effect of formation damage encountered with conventional drilling fluids.

Drilling operations at the Nevada Test Site  

SciTech Connect

The Nevada Operations Office (NV) is responsible for supporting the nuclear test programs of the Los Alamos and Lawrence Livermore National Laboratories. This support includes the drilling of test holes for nuclear device testing a the Nevada Test Site (NTS). The purpose of this audit was to assess the effectiveness of the Department of Energy's management of test hole inventories at the NTS. Our audit disclosed that NV accumulated a large inventory of unused test holes and approved drilling additional holes for which neither laboratory (Los Alamos nor Livermore) had identified a need. The overdrilling of test holes occurred because NV did not comply with good inventory practices that would have had NV's approving official question the need for, and the timing of, the laboratories' drilling requests. Instead, NV gave perfunctory approval to the laboratories' work orders for drilling test holes, and emphasized keeping two drill rig crews busy and satisfying the laboratories' demands for dedicated drilling personnel. Although NV did not agree that overdrilling had occurred, it has cut back its drilling activities and estimated that this will save abut $7.6 million annually. NV agreed with the recommendations in the report and has taken corrective actions.

Formation damage in underbalanced drilling operations  

E-Print Network (OSTI)

Formation damage has long been recognized as a potential source of reduced productivity and injectivity in both horizontal and vertical wells. From the moment that the pay zone is being drilled until the well is put on production, a formation is exposed to a series of fluids and operations that can reduce its productive capacity. Any process that causes a loss in the productivity of an oil-, gas-, or water-saturated formation has a damaging effect on the reservoir. These damage mechanisms predominantly fall into three major classifications: mechanical, chemical, and biological. Underbalanced drilling operations involve drilling a portion of the wellbore at fluid pressures less than that of the target formation. This technology has been used to prevent or minimize problems associated with invasive formation damage, which often greatly reduces the productivity of oil and gas reservoirs, mainly in openhole horizontal-well applications. Underbalanced drilling is not a solution for all formation-damage problems. Damage caused by poorly designed and/or executed underbalanced drilling programs can equal or exceed that which may occur with a well-designed conventional overbalanced drilling program. Four techniques are currently available to achieve underbalanced conditions while drilling. These include using lightweight drilling fluids, injecting gas down the drillpipe, injecting gas into a parasite string, and using foam. This study provides an analysis of a number of potential damage mechanisms present when drilling underbalanced. It describes each one and its influence on the productivity of a well. Additionally it presents a general description of the different techniques that can be applied to carry out successful, cost-effective UBD operations, and discusses how these techniques may be used to reduce or eliminate formation damage.

Development and Testing of Insulated Drill Pipe  

DOE Green Energy (OSTI)

This project has comprised design, analysis, laboratory testing, and field testing of insulated drill pipe (IDP). This paper will briefly describe the earlier work, but will focus on results from the recently-completed field test in a geothermal well. Field test results are consistent with earlier analyses and laboratory tests, all of which support the conclusion that insulated drill pipe can have a very significant effect on circulating fluid temperatures. This will enable the use of downhole motors and steering tools in hot wells, and will reduce corrosion, deterioration of drilling fluids, and heat-induced failures in other downhole components.

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.

Test report for core drilling ignitability testing  

DOE Green Energy (OSTI)

Testing was carried out with the cooperation of Westinghouse Hanford Company and the United States Bureau of Mines at the Pittsburgh Research Center in Pennsylvania under the Memorandum of Agreement 14- 09-0050-3666. Several core drilling equipment items, specifically those which can come in contact with flammable gasses while drilling into some waste tanks, were tested under conditions similar to actual field sampling conditions. Rotary drilling against steel and rock as well as drop testing of several different pieces of equipment in a flammable gas environment were the specific items addressed. The test items completed either caused no ignition of the gas mixture, or, after having hardware changes or drilling parameters modified, produced no ignition in repeat testing.

Underbalanced drilling benefits now available offshore  

Science Conference Proceedings (OSTI)

Offshore underbalanced drilling (UBD) is a reality. Applications in older, partially depleted fields and new fields are being considered. However, low productivity reservoirs and fields with sub normal pressures causing drilling problems are currently the main targets for offshore UBD. With proper planning and the correct technique, both jointed pipe and coiled tubing UBD drilling operations have been carried out offshore with success. The main concerns for offshore UBD have been altered drilling practices and surface production system operation. These issues have been examined and equipment has been designed and tested to address them. Environmental, safety and health issues are paramount and have been studied carefully. Detailed well planning, engineering, and flow modeling have proven critical for successful offshore UBD operations. Examples are given from oil and gas fields.

Field results document underbalanced drilling success  

Science Conference Proceedings (OSTI)

Many different techniques are used to maintain underbalanced conditions at the toolface. Whether the operator is trying to avoid drilling problems or prevent formation damage, the key to a safe, successful operation is a reliable method of sealing around the tubulars at the surface for continuous well control. Globally, underbalanced drilling (UBD) is emerging as an important technology to improve production and solve drilling problems with success in many applications with different reservoirs. Improvements in initial flow rates using UBD are being supported by longer term production. UBD techniques and processes are improving through experience and implementation. UBD is becoming a more economical means to optimize reservoir management than conventional overbalanced operations. UBD operations are proving to be safer than conventional overbalanced drilling.

Portable top drive cuts horizontal drilling costs  

SciTech Connect

Economic analysis of a seven-well, long-reach horizontal drilling program into an unconsolidated, heavy-oil-bearing reservoir in Winter field near the Alberta/Saskatchewan border in Canada reveals that -- in the right application -- renting a portable top drive drilling system can reduce total drilling costs. Use of the portable top drive combined with other cost-saving measures enabled Saskoil, one of Canada`s larger independents, to drill more cheaply, on a cost-per-meter basis, in 1993 than in 1992. This was despite significant rental rates for drilling rigs and directional drilling services caused by increased demand in Western Canada. Total cost savings of 10% on wells that would otherwise cost in the (C) $500,000 range are believed realistic. Based on this year`s performance, Saskoil recommends top drive for the company`s future horizontal wells in this area. This article describes the operator`s horizontal well program, advantages of top drive in that program and how it was installed and applied. Estimated time savings for six wells, plus other ways top drive can cut costs and improve operations are discussed.

Drilling techniques presently in use by the Geothermal Studies Project, US Geological Survey  

DOE Green Energy (OSTI)

The heat-flow studies program has evolved from one in which holes drilled for other purposes (mining and oil exploration, nuclear tests, hydrologic studies, etc.) provided the bulk of the data to a program in which the free holes, while still providing cost-effective and useful data, are being supplemented increasingly by holes drilled specifically for heat-flow determinations at locations where thermal data of high quality are needed, and where nobody else is interested in drilling. Ideally, heat-flow holes should be located in areas with moderate local relief and should be completed so that vertical water movement is inhibited. The most satisfactory test media for heat-flow determinations are crystalline rocks (particularly granites) and unconsolidated sediments; carbonate rocks and volcanic terranes can provide useful heat-flow data, but they present greater challenges both in drilling and interpretation. Drilling techniques have evolved from that of the continuously cored diamond-drilled hole (adapted from mining exploration) to adaptations of the shot-hole and blast-hole techniques used in petroleum exploration, water-well construction, and quarry operations. Spot cores are obtained where necessary to provide specific petrologic, geochemical, and physical data, but primary reliance is placed on ditch samples from rotary or percussion drilling for routine measurements of thermal conductivity and heat production. In shallow (50 to 100 m) holes in low temperature environments, plastic casing is used to maintain access for later temperature measurements. For deeper holes, steel casing is preferred. The annulus between casing and borehole wall in the lowermost 50 to 80 meters of heat-flow holes is routinely grouted off with a specially designed mixture of cement, bentonite, salt, and water to prevent vertical water movement.

Deep drilling technology for hot crystalline rock  

SciTech Connect

The development of Hot Dry Rock (HDR) geothermal systems at the Fenton Hill, New Mexico site has required the drilling of four deep boreholes into hot, Precambrian granitic and metamorphic rocks. Thermal gradient holes, four observation wells 200 m (600 ft) deep, and an exploration core hole 800 m (2400 ft) deep guided the siting of the four deep boreholes. Results derived from the exploration core hole, GT-1 (Granite Test No. 1), were especially important in providing core from the granitic rock, and establishing the conductive thermal gradient and heat flow for the granitic basement rocks. Essential stratigraphic data and lost drilling-fluid zones were identified for the volcanic and sedimentary rocks above the contact with the crystalline basement. Using this information drilling strategies and well designs were then devised for the planning of the deeper wells. The four deep wells were drilled in pairs, the shallowest were planned and drilled to depths of 3 km in 1975 at a bottom-hole temperature of nearly 200/sup 0/C. These boreholes were followed by a pair of wells, completed in 1981, the deepest of which penetrated the Precambrian basement to a vertical depth of 4.39 km at a temperature of 320/sup 0/C.

Drilling costs drop 7% in 1985  

SciTech Connect

Drilling costs dropped about 7% last year. This decline cancels a slight increase in 1984. Total costs to drill now run about 59% of the 1981 highs. Comparable figures for the previous 2 years are 63 and 61%. Deeper wells showed the biggest drops. Shallow well costs fell about 6%. Energy Information Administration (EIA) indexes drilling costs on a 1976 base year. Costs for shallow wells (5,000 ft or less) show an index about 138. Deeper wells have an index around 149. Cost declines were the greatest in West and North Texas and the Rockies, of 11%. The Northeast and Western areas showed greater than average declines, 9% or so. The High Plains, New Mexico, and Midcontinent areas recorded near the average 7% decline. Costs in South Louisiana, the Southeast, and Ark-La-Tex 2%. West Central Texas costs were off only 1%. The Southeast was essentially unchanged. Indexes by area show generally that drilling costs have declined since 1983. The summary here comes from EIA's ''Indexes and Estimates of Domestic Well Drilling Costs 1984 and 1985''. That report covers oil, gas, and dry hole costs, cost components, and overall costs.

Independent one-way acting hydraulic jar sections for a rotary drill string  

SciTech Connect

First and second separate one-way acting hydraulic jar sections each include inner and outer telescopically arranged tubular members with means for connecting one end of each the inner and outer tubular members of each jar section in the drill string. Spaced seal means between the inner and outer tubular members form a chamber in each jar section for confining hydraulic operating fluid. Hydraulic jar means are formed by cooperating means on the inner and outer tubular members within each operating fluid chamber. The cooperating means is spaced axially and disengaged in each fluid chamber when the drill string is in tension and compression during rotary drilling operation to inhibit damage and wear thereto. The hydraulic jar means in the first jar section is constructed to deliver an up jar and the jar means in the separate second jar section is constructed to deliver a down jar to the drill string. Drive means in a sealed chamber in each jar section connect the inner and outer tubular members of each jar section to allow relative longitudinal movement while preventing relative rotation therebetween. Means to equalize pressure adjacent one end of each of the chambers with the pressure in the well bore is provided in each jar section, which accommodates relative longitudinal movement of the inner and outer tubular members of each jar section for selectively creating an up or down jarring force independently of the well bore pressure.

Systems Study Of Drilling For Installation Of Geothermal Heat Pumps  

E-Print Network (OSTI)

Geothermal, or ground-source, heat pumps (GHP) are much more efficient than air-source units such as conventional air conditioners. A major obstacle to their use is the relatively high initial cost of installing the heat-exchange loops into the ground. In an effort to identify drivers which influence installation cost, a number of site visits were made during 1996 to assess the state-of-the-art in drilling for GHP loop installation. As an aid to quantifying the effect of various drilling-process improvements, we constructed a spread-sheet based on estimated time and material costs for all the activities required in a typical loop-field installation. By substituting different (improved) values into specific activity costs, the effect on total project costs can be easily seen.

Science Conference Proceedings (OSTI)

The Paducah Gaseous Diffusion Plant (PGDP) is a uranium enrichment facility owned by the US Department of Energy (DOE). A residual of the uranium enrichment process is depleted uranium hexafluoride (UF6). Depleted UF6, a solid at ambient temperature, is stored in 32,200 steel cylinders that hold a maximum of 14 tons each. Storage conditions are suboptimal and have resulted in accelerated corrosion of cylinders, increasing the potential for a release of hazardous substances. Consequently, the DOE is proposing refurbishment of certain existing yards and construction of a new storage yard. This environmental assessment (EA) evaluates the impacts of the proposed action and no action and considers alternate sites for the proposed new storage yard. The proposed action includes (1) renovating five existing cylinder yards; (2) constructing a new UF6 storage yard; handling and onsite transport of cylinders among existing yards to accommodate construction; and (4) after refurbishment and construction, restacking of cylinders to meet spacing and inspection requirements. Based on the results of the analysis reported in the EA, DOE has determined that the proposed action is not a major Federal action that would significantly affect the quality of the human environment within the context of the National Environmental Policy Act of 1969. Therefore, DOE is issuing a Finding of No Significant Impact. Additionally, it is reported in this EA that the loss of less than one acre of wetlands at the proposed project site would not be a significant adverse impact.

Method for laser drilling subterranean earth formations  

DOE Patents (OSTI)

Laser drilling of subterranean earth formations is efficiently accomplished by directing a collimated laser beam into a bore hole in registry with the earth formation and transversely directing the laser beam into the earth formation with a suitable reflector. In accordance with the present invention, the bore hole is highly pressurized with a gas so that as the laser beam penetrates the earth formation the high pressure gas forces the fluids resulting from the drilling operation into fissures and pores surrounding the laser-drilled bore so as to inhibit deleterious occlusion of the laser beam. Also, the laser beam may be dynamically programmed with some time dependent wave form, e.g., pulsed, to thermally shock the earth formation for forming or enlarging fluid-receiving fissures in the bore.

DOE Patents (OSTI)

A robust data transmission element for transmitting information between downhole components, such as sections of drill pipe, in the presence of hostile environmental conditions, such as heat, dirt, rocks, mud, fluids, lubricants, and the like. The data transmission element components include a generally U-shaped annular housing, a generally U-shaped magnetically conductive, electrically insulating element such as ferrite, and an insulated conductor. Features on the magnetically conducting, electrically insulating element and the annular housing create a pocket when assembled. The data transmission element is filled with a polymer to retain the components within the annular housing by filling the pocket with the polymer. The polymer can bond with the annular housing and the insulated conductor but preferably not the magnetically conductive, electrically insulating element. A data transmission element is mounted within a recess proximate a mating surface of a downhole drilling component, such as a section of drill pipe.

Drilling in 2000 taps technology explosion  

Science Conference Proceedings (OSTI)

While major oil and gas companies all but ended research and development programs, the burden for technological advancement fell to service companies. And service companies allotted their R and D investment to activities whose return they could fairly predict. But even as cost-cutting measured devastated engineering staffs, a profit-growth strategy was forming that understood that profit could be enhanced by not just cutting the per barrel cost to producers but by producing more barrels per investment dollar. In other words, get more oil and gas from the same well through applied drilling and production technology. In the drilling industry all things technical revolve around six areas of expertise: bits, rotation systems, tripping systems, control systems, information systems and direction drilling systems. The paper discusses these six technologies.

New surface equipment for underbalanced drilling  

Science Conference Proceedings (OSTI)

Perhaps the single most exciting development in the area of new drilling technology in this decade is underbalanced drilling (UBD). This category includes both jointed pipe and coiled tubing applications. Each has advantages and disadvantages in UBD operations. Regardless of the method selected for a particular UBD application, equipment similarities exist. The surface control and production equipment must be correctly sized and designed for the overall total UBD engineering solution. This article describes the various types, applications and purposes of special surface equipment needed in underbalanced operations. This is the second in a series of articles on UBD technology and its rapid development is this field.

Stress analysis of a hybrid composite drilling riser  

E-Print Network (OSTI)

Methods to thoroughly and efficiently analyze a composite riser designed for use in offshore drilling applications and subjected to various types of loading have been developed. An axisymmetric finite element model allowing nonaxisymmetric deformations has been constructed. 'the model was simplified by exploiting symmetries in the lay-up of the composite to homogenize material properties. Postprocessing techniques to recover ply level stresses and strains and determine lamina failures were also developed. The analysis is demonstrated on an industry-designed riser, and the results show that the current design is unacceptable. Even at normal operating loads, there is some failure and some very high stress levels. The analysis is used to suggest modifications to the baseline design.

DOE Patents (OSTI)

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.

This report summarizes the well installation activities conducted during the federal fiscal year (FY) 1995 drilling program at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee (including activities that were performed in late FY 1994, but not included in the FY 1994 Well Installation Program Summary Report). Synopses of monitoring well construction/well development data, well location rationale, geological/hydrological observations, quality assurance/quality control methods, and health and safety monitoring are included. Three groundwater monitoring wells and two gas monitoring probes were installed during the FY 1995 drilling program. One of the groundwater monitoring wells was installed at Landfill VI, the other two in the Boneyard/Burnyard area. All of the groundwater monitoring wells were constructed with stainless steel screens and casings. The two gas monitoring probes were installed at the Centralized Sanitary Landfill II and were of polyvinyl chloride (PVC) screened construction. Eleven well rehabilitation/redevelopment efforts were undertaken during FY 1995 at the Y-12 Plant. All new monitoring wells and wells targeted for redevelopment were developed by either a 2.0-in. diameter swab rig or by hand bailing until nonspecific parameters (pH and specific conductance) attained steady-state levels. Turbidity levels were lowered, if required, to the extent practicable by continued development beyond a steady-state level of pH and conductance.

Analyzing the dynamic behavior of downhole equipment during drilling  

DOE Green Energy (OSTI)

Advanced geothermal drilling systems will require a bottom hole assembly (BHA) which utilizes sophisticated electronic and mechanical equipment to accomplish faster, more trouble free, smarter drilling. The bit-drill string/formation interaction during drilling imposes complex, intermittent dynamic loading on the downhole equipment. A finite element computer code, GEODYN, is being developed to allow analysis of the structural response of the downhole equipment during drilling and to simulate the drilling phenomena (i.e. penetration, direction, etc.). Phase 1 GEODYN, completed early in 1984, provides the capability to model the dynamic response of a polycrystalline diamond compact (PDC) bit interacting with a non-homogeneous formation. Succeeding development phases will allow inclusion of stabilizers and, eventually, the entire drill string in addition to facilitating drill ahead simulation.

Monitoring downhole pressures and flow rates critical for underbalanced drilling  

Science Conference Proceedings (OSTI)

True underbalanced drilling, and not just flow drilling, requires thorough engineering and monitoring of downhole pressures and flow rates to ensure the formations are drilled without formation damage. Underbalanced drilling involves intentionally manipulating the bottom hole circulating pressure so that it is less than static reservoir pressure. This underbalanced pressure condition allows reservoir fluids to enter the well bore while drilling continues, preventing fluid loss and many causes of formation damage. Applied correctly, this technology can address problems of formation damage, lost circulation, and poor penetration rates. Another important benefit of drilling underbalanced is the ability to investigate the reservoir in real time. The paper discusses the reasons for under balanced drilling, creating underbalance, well site engineering, fluids handling, rotating flow divertor injection gas, survey techniques, data acquisition, operations, maintaining under-balance, routine drilling, rate of penetration, misconceptions, and economics.

Coiled tubing drilling requires economic and technical analyses  

Science Conference Proceedings (OSTI)

Field experience has proven that coiled tubing drilling is a technical and economic option on some wells; however, coiled tubing drilling is not the solution to every drilling prospect or production-enhancement job. To determine if coiled tubing drilling is viable, the geographic, technical, and economic aspects of each project must be considered in detail. Generally, with some limitations, coiled tubing drilling is feasible primarily when jointed pipe cannot be used effectively. Also, coiled tubing drilling may be more appropriate because of some special well site requirements, such as environmental regulations requiring less surface disturbance. The paper discusses technical considerations which need to be considered, economic feasibility, limitations of well types (new shallow wells, conventional reentry, through-tubing reentry, and underbalanced drilling), and outlook for further growth in the coiled tubing drilling industry.

Practical applications of a drilling data center  

SciTech Connect

Tenneco Oil is using a real-time drilling-data acquisition, telemetry, data base, and applications-program system for Gulf of Mexico operations. The system provides for data acquisition in real time from commercially available logging units. The data are transmitted into a central office onshore via microwave or satellite telemetry links. Up to 352 drilling parameters are transmitted from each computerized logging unit and archived in the data base every 20 sec. Parameters can include measurement-while-drilling (MWD) data as well as mud-logging data. Applications programs utilizing these parameters are available in the central site data center (CSDC) and in locations throughout Tenneco's facilities in Lafayette, La. Access to the CSDC and its computing power is also available on the offshore rig. Backup surveillance of critical drilling parameters is provided through alarms and continuous monitoring of the parameters, thus providing for a safer operation. Rig efficiency has also been improved through analysis of the data and comparison of the data between various rig operations and rigs. Both tangible and intangible cost savings are discussed.

Liability issues surrounding oil drilling mud sumps  

Science Conference Proceedings (OSTI)

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.

An Industry/DOE Program to Develop and Benchmark Advanced Diamond Product Drill Bits and HP/HT Drilling Fluids to Significantly Improve Rates of Penetration  

Science Conference Proceedings (OSTI)

A deep drilling research program titled 'An Industry/DOE Program to Develop and Benchmark Advanced Diamond Product Drill Bits and HP/HT Drilling Fluids to Significantly Improve Rates of Penetration' was conducted at TerraTek's Drilling and Completions Laboratory. Drilling tests were run to simulate deep drilling by using high bore pressures and high confining and overburden stresses. The purpose of this testing was to gain insight into practices that would improve rates of penetration and mechanical specific energy while drilling under high pressure conditions. Thirty-seven test series were run utilizing a variety of drilling parameters which allowed analysis of the performance of drill bits and drilling fluids. Five different drill bit types or styles were tested: four-bladed polycrystalline diamond compact (PDC), 7-bladed PDC in regular and long profile, roller-cone, and impregnated. There were three different rock types used to simulate deep formations: Mancos shale, Carthage marble, and Crab Orchard sandstone. The testing also analyzed various drilling fluids and the extent to which they improved drilling. The PDC drill bits provided the best performance overall. The impregnated and tungsten carbide insert roller-cone drill bits performed poorly under the conditions chosen. The cesium formate drilling fluid outperformed all other drilling muds when drilling in the Carthage marble and Mancos shale with PDC drill bits. The oil base drilling fluid with manganese tetroxide weighting material provided the best performance when drilling the Crab Orchard sandstone.

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.

High pressure drilling system triples ROPS, stymies bit wear  

Science Conference Proceedings (OSTI)

Recent West Texas field tests of an experiental high-pressure drilling system have nearly tripled typical penetration rates in hard dolomite while putting virtually no visible wear on the bits, even those designed for much softer formations. With this drilling system, developed by FlowDril Corp. of Kent, Wash., and their joint-venture partner Grace Drilling Co., clarified drilling fluids (minimum solids) are pressurized to nearly 30,000 psi and directed to the bottom of the hole through a special nozzle attached to the drill bit. The action of this high pressure stream augments the bit's job, resulting in higher ROPs and decreased bit wear.

GRAIN-SCALE FAILURE IN THERMAL SPALLATION DRILLING  

DOE Green Energy (OSTI)

Geothermal power promises clean, renewable, reliable and potentially widely-available energy, but is limited by high initial capital costs. New drilling technologies are required to make geothermal power financially competitive with other energy sources. One potential solution is offered by Thermal Spallation Drilling (TSD) - a novel drilling technique in which small particles (spalls) are released from the rock surface by rapid heating. While TSD has the potential to improve drilling rates of brittle granitic rocks, the coupled thermomechanical processes involved in TSD are poorly described, making system control and optimization difficult for this drilling technology. In this paper, we discuss results from a new modeling effort investigating thermal spallation drilling. In particular, we describe an explicit model that simulates the grain-scale mechanics of thermal spallation and use this model to examine existing theories concerning spalling mechanisms. We will report how borehole conditions influence spall production, and discuss implications for macro-scale models of drilling systems.

Integrating surface systems with downhole data improves underbalanced drilling  

Science Conference Proceedings (OSTI)

An integrated approach of using special downhole sensors and transmission capabilities in conjunction with a surface drilling optimization system has improved the management and understanding of the underbalanced drilling environment within a closed loop system. Improving the underbalanced drilling operation and obtaining quality data in real time can help eliminate damage to the formation and increase ultimate production. Recent advances in drilling technology have made it possible to drill horizontal wells underbalanced more safely and effectively. This technology has greatly reduced the potential for skin damage to the bore hole. Experience from western Canadian underbalanced horizontal drilling clearly demonstrates that a well bore`s initial productive potential is very accurately predicted from its productive behavior during drilling operations.

Horizontal flow drilling requires focus on well control  

Science Conference Proceedings (OSTI)

Horizontal wells drilled underbalanced or while flowing must have surface equipment and a blow-out preventer stack specially designed for circulating operations. Functional well control methods for drilling horizontal wells have been developed in specific regions worldwide. Special safety equipment and procedures, however, are still required in most horizontal development applications. The challenge for horizontal drilling development and underbalanced drilling is to overcome the obstacles of government regulation, reduce pollution dangers, and improve personnel and equipment safety. Well control techniques tailored to the demands of each field can help overcome these challenges. Several well control elements must be addressed carefully on each horizontal well: drilling fluid requirements, well control procedures and equipment, and surface equipment and special considerations for handling hydrocarbons produced while drilling. The paper discusses each of these elements for underbalanced horizontal drilling.

How borehole ballooning alters drilling responses  

Science Conference Proceedings (OSTI)

From field observations of drilling and hole instability problems over a 30-year period, a new and more complete understanding of plastic well-bore behavior - under certain pressure imbalance conditions - is being developed and verified with detailed well histories. Rock mechanics theory, thus far primarily concerned with plastic behavior and borehole collapse on the underbalanced side, is in at least partial agreement with these observations. This article further elaborates on the pressure-responsive plastic behavior of shales under tremendous downhole stresses, particularly in the overbalanced, ballooning mode. The primary subject matter of the article is divided into the following areas: Stable operating margin; Plastic behavior region; Wellbore wall yields; Brittle sloughings; Loss of mud; Gain of mud; Shut-in pressure; Reflex gas; Charged RFT's; Preexisting balloon; Drilling rate.

Self propelled drilling rig starts offshore exploration  

SciTech Connect

Ocean Drilling and Exploration Co. recently commissioned its new $12 million self-propelled, semisubmersible drilling rig, Ocean Prospector, at Mitsubishi Shipyard, Japan, where the rig was built. Initial trail runs completed adjacent to the shipyard indicated that the ship has a speed of 7 kn ahead and 3 kn astern. Steering also is reported to be excellent. The rig has a minimum turning radius of approx. 2 barge lengths and shows instant response. This rig is powered by 4 Fairbanks Morse, 10-cylinder opposed piston, model 38D8-1/8 diesel engines. Each engine is rated at 1,600 hp at 720 rpm and they drive eight 1,600 kw, traction type D-C generators and two 1,000 kw A-C generators. The rated operating depth of the unit afloat is 600 ft of water. The overall length of Ocean Prospector is just over 344 ft, with the beam measuring 263-1/2 ft. During transit, when the rig will be completely deballasted, it will have a draft of approx. 20 ft. When it reaches the drilling site, ballast water will be pumped into the 18 ballast tanks until the draft is increased to 70 ft. At this point, the underside of the main deck will be 50 ft above the mean surface of the sea. Drilling operations will be conducted while the rig is at the 70 ft draft. The mooring system will consist of eight 2-3/4 in. chains, each measuring 3,300 ft in length and connected to a 15-ton anchor.

Research drilling in young silicic volcanoes  

DOE Green Energy (OSTI)

Magmatic activity, and particularly silicic magmatic activity, is the fundamental process by which continental crust forms and evolves. The transport of magma from deep crustal reservoirs to the surface is a neglected but important aspect of magmatic phenomena. It encompasses problems of eruptive behavior, hydrothermal circulation, and ore deposition, and must be understood in order to properly interpret deeper processes. Drilling provides a means for determining the relationship of shallow intrusive processes to eruption processes at young volcanoes where eruptions are best understood. Drilling also provides a means for directly observing the processes of heat and mass transfer by which recently emplaced intrusions approach equilibrium with their new environment. Drilling in the Inyo Chain, a 600-year-old chain of volcanic vents in California, has shown the close relationship of silicic eruption to shallow dike emplacement, the control of eruptive style by shallow porous-flow degassing, the origin of obsidian by welding, the development of igneous zonation by viscosity segregation, and the character and size of conduits in relation to well-understood magmatic and phreatic eruptions. 36 refs., 9 figs.

Evaluation of commercially available geothermal drilling fluids  

DOE Green Energy (OSTI)

A review of geothermal drilling in the United States has revealed that serious problems are being encountered with corrosion and degradation of drilling fluids in high temperature wells. The best high temperature drilling fluids that could be formulated from commercially available materials were obtained from the five largest mud companies. These included samples of 9 and 18 lb/gal water muds and 18 lb/gal oil muds. Over 4,000 tests were conducted on these muds to evaluate their performance at high temperature. This included testing at temperatures to 550/sup 0/F and pressures to 15,000 psi. These tests revealed that most of the water muds had high viscosity, high filtration rates and poor corrosivity characteristics at temperatures above 350/sup 0/F. Although the oil muds performed better than water muds at high temperatures, some problems were encountered with viscosity at temperatures above 450/sup 0/F and with filtration at temperatures above 500/sup 0/F. Generally the corrosivity characteristics of the oil muds were much better than those of the water muds. Overall, oil muds have better temperature stability than water muds but their use is often limited because of problems with surface pollution, contamination of water zones and reservoir damage. Biodegradable oil mud systems would overcome some of these limitations.

Borehole measurements while drilling: systems and activities  

DOE Green Energy (OSTI)

Attention is focused on all potential methods of drilling safer and cheaper. Real time data from the bit offers the greatest potential for meeting these needs. As a result, numerous companies are actively competing to develop this oil field service capability and to capture a world wide market. Two basic categories of service are sought. The first, and highest priority, is drilling safety and efficiency; the second is real-time logging, or formation evaluation. This study addresses the types of systems being studied, describes company activity and projects underway, estimates the practical potential for success and considers the commercial market for successful systems. The need for research data on bit hydraulics and drill string dynamics, special deep, hot or sour gas situations and other relatively unusual requirements may become exceptions to the general conclusions that are drawn. Historical and present activity are documented through presenting the results of extensive literature and patent researches. A breakdown is presented of activity by company along with names and addresses for further contact.

Construction computer-aided engineering  

SciTech Connect

Hitachi Ltd. and Bechtel Power Corporation are presently designing nuclear power plants for Japanese utilities exclusively on three-dimensional computer-aided design and drafting (CADD) systems. To make these three-dimensional CADD models more effective for construction activities, Hitachi and Bechtel are jointly developing a software package that allows construction engineers and planners to effectively empty an area of the three-dimensional CADD model and rebuild it electronically to simulate, animate, and optimize the construction sequence and methodology. The components in the three-dimensional CADD model are placed as they would be for actual construction (i.e., piping spool pieces, skid-mounted systems, piping, and equipment modules, etc.). The construction engineer and planners can then select the components along with appropriate handling equipment and simulate/animate the actual construction sequence. After the construction sequence has been optimized, it is captured on videotape for use in the field. The results of the simulated activities are then passed on to computer program module (CPM) scheduling and work breakdown structure programs for accurate bottom-up construction activity planning and commodity tracking. This entire process can be iterated to an optimum solution before the actual construction begins. Once construction is in progress, the program can compare the actual status and allow resimulations for workarounds.

PUMP CONSTRUCTION  

DOE Patents (OSTI)

A pump which utilizes the fluid being pumped through it as its lubricating fluid is described. This is achieved by means of an improved bearing construction in a pump of the enclosed or canned rotor type. At the outlet end of the pump, adjacent to an impeller mechanism, there is a bypass which conveys some of the pumped fluid to a chamber at the inlet end of the pump. After this chamber becomes full, the pumped fluid passes through fixed orifices in the top of the chamber and exerts a thrust on the inlet end of the pump rotor. Lubrication of the rotor shaft is accomplished by passing the pumped fluid through a bypass at the outlet end of the rotor shaft. This bypass conveys Pumped fluid to a cooling means and then to grooves on the surface of the rotor shait, thus lubricating the shaft.

Hydrothermal Spallation Drilling System for EGS Geothermal Hydrothermal Spallation Drilling System for EGS Geothermal Project Jump to: navigation, search Last modified on July 22, 2011. Project Title Development of a Hydrothermal Spallation Drilling System for EGS Project Type / Topic 1 Recovery Act: Enhanced Geothermal Systems Component Research and Development/Analysis Project Type / Topic 2 Drilling Systems Project Description Potter Drilling has recently demonstrated hydrothermal spallation drilling in the laboratory. Hydrothermal spallation drilling creates boreholes using a focused jet of superheated water, separating individual grains ("spalls") from the rock surface without contact between the rock and the drill head. This process virtually eliminates the need for tripping. Previous tests of flame-jet spallation achieved ROP of 50 ft/hr and higher in hard rock with minimal wear on the drilling assembly, but operating this technology in an air-filled borehole created challenges related to cuttings transport and borehole stability. The Potter Drilling system uses a water based jet technology in a fluid-filled borehole and as a result has the potential to achieve similarly high ROP that is uncompromised by stability or cuttings transport issues.

Development and Manufacture of Cost Effective Composite Drill Pipe  

SciTech Connect

This technical report presents the engineering research, process development and data accomplishments that have transpired to date in support of the development of Cost Effective Composite Drill Pipe (CDP). The report presents progress made from October 1, 2004 through September 30, 2005 and contains the following discussions: (1) Qualification Testing; (2) Prototype Development and Testing of ''Smart Design'' Configuration; (3) Field Test Demonstration; and (4) Commercial order for SR-CDP from Torch International. The objective of this contract is to develop and demonstrate ''cost effective'' Composite Drill Pipe. It is projected that this drill pipe will weigh less than half of its steel counter part. The resultant weight reduction will provide enabling technology that will increase the lateral distance that can be reached from an offshore drilling platform and the depth of water in which drilling and production operations can be carried out. Further, composite drill pipe has the capability to carry real time signal and power transmission within the pipe walls. CDP can also accommodate much shorter drilling radius than is possible with metal drill pipe. As secondary benefits, the lighter weight drill pipe can increase the storage capability of floating off shore drilling platforms and provide substantial operational cost savings.

Workshop on magma/hydrothermal drilling and instrumentation  

DOE Green Energy (OSTI)

The discussions, conclusions, and recommendations of the Magma/Hydrothermal Drilling and Instrumentation Workshop, Albuquerque, NM, May 31--June 2, 1978 are summarized. Three working groups were organized as follows: Drilling Location and Environment, Drilling and Completion Technology, and Logging and Instrumentation Technology. The first group discussed potential drilling sites and the environment that could be expected in drilling to magma depth at each site. Sites suggested for early detailed evaluation as candidate drilling sites were The Geysers-Clear Lake, CA, Kilauea, HI, Long Valley-Mono Craters, CA, and Yellowstone, WY. Magma at these sites is expected to range from 3 to 10 km deep with temperatures of 800 to 1100{sup 0}C. Detailed discussions of the characteristics of each site are given. In addition, a list of geophysical measurements desired for the hole is presented. The Drilling and Completion Group discussed limitations on current rotary drilling technology as a function of depth and temperature. The group concluded that present drilling systems can be routinely used to temperatures of 200{sup 0}C and depths to 10 km; drilling to 350{sup 0}C can be accomplished with modifications of present techniques, drilling at temperatures from 350{sup 0}C to 1100{sup 0}C will require the development of new drilling techniques. A summary of the limiting factors in drilling systems is presented, and recommendations for a program directed at correcting these limitations is described. The third group discussed requirements for instrumentation and established priorities for the development of the required instruments. Of highest priority for development were high resolution temperature tools, sampling techniques (core, formation fluids), chemical probes, and communications techniques. A description of instrumentation requirements for the postulated hole is given, and the tasks necessary to develop the required devices are delineated.

Drilling and Production Testing the Methane Hydrate Resource Potential Associated with the Barrow Gas Fields  

SciTech Connect

In November of 2008, the Department of Energy (DOE) and the North Slope Borough (NSB) committed funding to develop a drilling plan to test the presence of hydrates in the producing formation of at least one of the Barrow Gas Fields, and to develop a production surveillance plan to monitor the behavior of hydrates as dissociation occurs. This drilling and surveillance plan was supported by earlier studies in Phase 1 of the project, including hydrate stability zone modeling, material balance modeling, and full-field history-matched reservoir simulation, all of which support the presence of methane hydrate in association with the Barrow Gas Fields. This Phase 2 of the project, conducted over the past twelve months focused on selecting an optimal location for a hydrate test well; design of a logistics, drilling, completion and testing plan; and estimating costs for the activities. As originally proposed, the project was anticipated to benefit from industry activity in northwest Alaska, with opportunities to share equipment, personnel, services and mobilization and demobilization costs with one of the then-active exploration operators. The activity level dropped off, and this benefit evaporated, although plans for drilling of development wells in the BGF's matured, offering significant synergies and cost savings over a remote stand-alone drilling project. An optimal well location was chosen at the East Barrow No.18 well pad, and a vertical pilot/monitoring well and horizontal production test/surveillance well were engineered for drilling from this location. Both wells were designed with Distributed Temperature Survey (DTS) apparatus for monitoring of the hydrate-free gas interface. Once project scope was developed, a procurement process was implemented to engage the necessary service and equipment providers, and finalize project cost estimates. Based on cost proposals from vendors, total project estimated cost is $17.88 million dollars, inclusive of design work, permitting, barging, ice road/pad construction, drilling, completion, tie-in, long-term production testing and surveillance, data analysis and technology transfer.

Restored drill cuttings for wetlands creation: Results of a two year mesocosm approach to emulate field conditions under varying hydrologic regimes  

Science Conference Proceedings (OSTI)

It is well documented that Louisiana has the highest rate of wetland loss in the United States. Deep-water channel dredging and leveeing of the Mississippi River since the 1930s have interrupted the natural delta cycle that builds new marshes through sediment deposition. Many of the areas that are subsiding and deteriorating are isolated from riverine sediment sources; therefore alternative methods to deposit sediment and build marshes must be implemented. This project demonstrates that the earthen materials produced when drilling oil and gas wells can be used as a suitable substrate for growing wetland plants. Drilling fluids (muds) are used to lubricate drill bits and stabilize the earth around drill holes and become commingled with the earthen cuttings. Two processes have been reported to restore drill cuttings to acceptable levels by removal of any toxic components found in drilling muds. The main objective of this project was to assess the potential of drill cuttings processed by these two methods in terms of their ability to support wetland vegetation and potential toxicity.

NETL: News Release - New Projects to Investigate Smart Drilling Options  

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

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.

Development and Manufacture of Cost-Effective Composite Drill Pipe  

SciTech Connect

Advanced Composite Products and Technology, Inc. (ACPT) has developed composite drill pipe (CDP) that matches the structural and strength properties of steel drill pipe, but weighs less than 50 percent of its steel counterpart. Funding for the multiyear research and development of CDP was provided by the U.S. Department of Energy Office of Fossil Energy through the Natural Gas and Oil Projects Management Division at the National Energy Technology Laboratory (NETL). Composite materials made of carbon fibers and epoxy resin offer mechanical properties comparable to steel at less than half the weight. Composite drill pipe consists of a composite material tube with standard drill pipe steel box and pin connections. Unlike metal drill pipe, composite drill pipe can be easily designed, ordered, and produced to meet specific requirements for specific applications. Because it uses standard joint connectors, CDP can be used in lieu of any part of or for the entire steel drill pipe section. For low curvature extended reach, deep directional drilling, or ultra deep onshore or offshore drilling, the increased strength to weight ratio of CDP will increase the limits in all three drilling applications. Deceased weight will reduce hauling costs and increase the amount of drill pipe allowed on offshore platforms. In extreme extended reach areas and high-angle directional drilling, drilling limits are associated with both high angle (fatigue) and frictional effects resulting from the combination of high angle curvature and/or total weight. The radius of curvature for a hole as small as 40 feet (12.2 meters) or a build rate of 140 degrees per 100 feet is within the fatigue limits of specially designed CDP. Other properties that can be incorporated into the design and manufacture of composite drill pipe and make it attractive for specific applications are corrosion resistance, non-magnetic intervals, and abrasion resistance coatings. Since CDP has little or no electromagnetic force fields up to 74 kilohertz (KHz), a removable section of copper wire can be placed inside the composite pipe to short the tool joints electrically allowing electromagnetic signals inside the collar to induce and measure the same within the rock formation. By embedding a pair of wires in the composite section and using standard drill pipe box and pin ends equipped with a specially developed direct contact joint electrical interface, power can be supplied to measurement-while-drilling (MWD) and logging-while-drilling (LWD) bottom hole assemblies. Instantaneous high-speed data communications between near drill bit and the surface are obtainable utilizing this 'smart' drilling technology. The composite drill pipe developed by ACPT has been field tested successfully in several wells nationally and internationally. These tests were primarily for short radius and ultra short radius directional drilling. The CDP in most cases performed flawlessly with little or no appreciable wear. ACPT is currently marketing a complete line of composite drill collars, subs, isolators, casing, and drill pipe to meet the drilling industry's needs and tailored to replace metal for specific application requirements.

Underbalanced drilling in the Piceance basin. Final report, June 1997  

Science Conference Proceedings (OSTI)

Underbalanced drilling technology is established and fairly well understood in some areas in the U.S. such as Appalachia. The primary objective of this cooperative project in the Piceance Basin was to use underbalanced drilling technologies to reduce rates of penetration such that significant cost reductions could occur. Fluids evaluated included air/mist, stiff foams and aerated muds. Underbalanced drilling was successful particularly in the surface hole; however, heaving shales in the Wasatch section were problematic.

Salton Sea Scientific Drilling Project: A summary of drilling and engineering activities and scientific results  

DOE Green Energy (OSTI)

The Salton Sea Scientific g Project (SSSDP) completed the first major well in the United States Continental Scientific Drilling Program. The well (State 2-14) was drilled to 10,W ft (3,220 m) in the Salton Sea Geothermal Field in California's Imperial Valley, to permit scientific study of a deep, high-temperature portion of an active geothermal system. The program was designed to investigate, through drilling and testing, the subsurface thermal, chemical, and mineralogical environments of this geothermal area. Extensive samples and data, including cores, cuttings, geothermal fluids and gases, and geophysical logs, were collected for future scientific analysis, interpretation, and publication. Short duration flow tests were conducted on reservoirs at a depth of approximately 6,120 ft (1,865 m) and at 10,136 ft (3,089 m). This report summarizes all major activities of the SSSDP, from project inception in the fall of 1984 through brine-pond cleanup and site restoration, ending in February 1989. This report presents a balanced summary of drilling, coring, logging, and flow-test operations, and a brief summary of technical and scientific results. Frequent reference is made to original records, data, and publication of results. The report also reviews the proposed versus the final well design, and operational summaries, such as the bit record, the casing and cementing program, and the coring program. Summaries are and the results of three flow tests. Several teamed during the project.

Compendium of regulatory requirements governing underground injection of drilling waste.  

Science Conference Proceedings (OSTI)

Large quantities of waste are produced when oil and gas wells are drilled. The two primary types of drilling wastes include used drilling fluids (commonly referred to as muds), which serve a variety of functions when wells are drilled, and drill cuttings (rock particles ground up by the drill bit). Some oil-based and synthetic-based muds are recycled; other such muds, however, and nearly all water-based muds, are disposed of. Numerous methods are employed to manage drilling wastes, including burial of drilling pit contents, land spreading, thermal processes, bioremediation, treatment and reuse, and several types of injection processes. This report provides a comprehensive compendium of the regulatory requirements governing the injection processes used for disposing of drilling wastes; in particular, for a process referred to in this report as slurry injection. The report consists of a narrative discussion of the regulatory requirements and practices for each of the oil- and gas-producing states, a table summarizing the types of injection processes authorized in each state, and an appendix that contains the text of many of the relevant state regulations and policies. The material included in the report was derived primarily from a review of state regulations and from interviews with state oil and gas regulatory officials.

The Technology Identification Module follows the philosophy of a waste management hierarchy. Waste management options with the lowest environmental impacts are encouraged ahead of those with more significant environmental impacts. The Technology Identification Module helps identify waste management options, but users should also consider their own site-specific costs and waste volumes. How it Works Users will be asked to answer a series of questions about the location of the well site, physical features of the site that may allow or inhibit the use of various options, whether the regulatory agency with jurisdiction allows or prohibits particular options, and whether cost or the user's company policy would preclude any options. Nearly all questions are set up for only "yes" or "no" responses. Depending on how the initial questions are answered, users will face from 15 to 35 total questions. Some of these can be answered immediately, while others may require some additional investigation of other portions of this web site or external information. Suitable options will be identified as users complete the questions, and users will be able to print out a summary of suitable options when the process is completed.

Directional Drilling and Equipment for Hot Granite Wells  

DOE Green Energy (OSTI)

Directional drilling technology was extended and modified to drill the first well of a subsurface geothermal energy extraction system at the Fenton Hill, New Mexico, hot dry rock (HDR) experimental site. Borehole geometries, extremely hard and abrasive granite rock, and high formation temperatures combined to provide a challenging environment for directional drilling tools and instrumentation. Completing the first of the two-wellbore HDR system resulted in the definition of operation limitations of -many conventional directional drilling tools, instrumentation, and techniques. The successful completion of the first wellbore, Energy Extraction Well No. 2 (EE-21), to a measured depth of 4.7 km (15,300 ft) in granite reservoir rock with a bottomhole temperature of 320 C (610 F) required the development of a new high-temperature downhole motor and modification of existing wireline-conveyed steering tool systems. Conventional rotary-driven directional assemblies were successfully modified to accommodate the very hard and abrasive rock encountered while drilling nearly 2.6 km (8,500 ft) of directional hole to a final inclination of 35{sup o} from the vertical at the controlled azimuthal orientation. Data were collected to optimize the drilling procedures far the programmed directional drilling of well EE-3 parallel to, and 370 metres (1,200 ft) above, Drilling equipment and techniques used in drilling wellbores for extraction of geothermal energy from hot granite were generally similar to those that are standard and common to hydrocarbon drilling practices. However, it was necessary to design some new equipment for this program: some equipment was modified especially for this program and some was operated beyond normal ratings. These tools and procedures met with various degrees of success. Two types of shock subs were developed and tested during this project. However, downhole time was limited, and formations were so varied that analysis of the capabilities of these items is not conclusive. Temperature limits of the tools were exceeded. EE-2. Commercial drilling and fishing jars were improved during the drilling program. Three-cone, tungsten-carbide insert bit performance with downhole motors was limited by rapid gauge wear. Rotary drilling was optimized for wells EE-2 and EE-3 using softer (IADS 635 code) bits and provided a balance between gauge,. cutting structure, and bearing life. Problems of extreme drill string drag, drill string twist-off, and corrosion control are discussed.

Pioneering work, economic factors provide insights into Russian drilling technology  

Science Conference Proceedings (OSTI)

In Russia and America, individual ingenuity and economic forces have produced a variety of drilling technologies, resulting in the development of disparate drilling systems. Endeavors by the US Department of Energy, the Gas Research Institute, Sandia Laboratories, and private industry have promoted exchanges of knowledge since the 1980s, and now that the barriers to technology transfer are being lifted, engineers from both countries have the opportunity to exchange knowledge and incorporate the best of both. The Russian drilling industry, like the Russian space program, has achieved tremendous success in implementing product and process innovations including the first directional (1940s), horizontal (1950s), and multilateral (1950s) wells. In addition, Russian engineers built the first turbodrills, electrodrills, novel drills (lasers, explosives), aluminum drill pipe, downhole electric submersible pumps, and mud hammers. This first part of a two-part series describes the achievements of Russian engineers in horizontal and multilateral drilling technologies followed by a discussion of the economic differences that led Russian and American drillers to develop dissimilar drilling systems. The second part describes a variety of innovative Russian technologies and provides details on the technical advantages they offer for the drilling process.

Evaluation of slurry injection technology for management of drilling wastes.  

Science Conference Proceedings (OSTI)

Each year, thousands of new oil and gas wells are drilled in the United States and around the world. The drilling process generates millions of barrels of drilling waste each year, primarily used drilling fluids (also known as muds) and drill cuttings. The drilling wastes from most onshore U.S. wells are disposed of by removing the liquids from the drilling or reserve pits and then burying the remaining solids in place (called pit burial). This practice has low cost and the approval of most regulatory agencies. However, there are some environmental settings in which pit burial is not allowed, such as areas with high water tables. In the U.S. offshore environment, many water-based and synthetic-based muds and cuttings can be discharged to the ocean if discharge permit requirements are met, but oil-based muds cannot be discharged at all. At some offshore facilities, drilling wastes must be either hauled back to shore for disposal or disposed of onsite through an injection process.

Drilling through gas hydrates formations: possible problems and suggested solution  

E-Print Network (OSTI)

Gas hydrate research in the last two decades has taken various directions ranging from ways to understand the safe and economical production of this enormous resource to drilling problems. as more rigs and production platforms move into deeper waters to its environmental impact on global warming and cooling. Gas hydrates are ice-like structures of a water lattice with cavities, which contain guest gases. Gas hydrates are stable at low temperatures and high pressures. The amount of energy trapped in gas hydrates all over the world is about twice the amount found in all recoverable fossil fuels today. This research identifies the problems facing the oil and gas industry as it drills in deeper waters where gas hydrates are present and suggests solutions to some of the problems. The problems considered in this research have been approached from a drilling point of view. Hence, the parameters investigated and discussed are drilling controlled parameters. They include rate of penetration, circulation rate and drilling fluid density. The rate of penetration in offshore wells contributes largely to the final cost of the drilling process. These 3 parameters have been linked in the course of this research in order to suggest an optimum rate of penetration. The results show the rate of penetration is directly proportional to the amount of gas released when drilling through gas hydrate. As the volume of gas released increases, the problems facing the drilling rigs, drilling crew and environment is seen to increase. The results also show the extent of risk to be expected while drilling through gas hydrate formations. A chart relating the rate of penetration, circulation rate and effective mud weight was used to select the optimum drilling rate within the drilling safety window. Finally, future considerations and recommendations in order to improve the analyses presented in this work are presented. Other drilling parameters proposed for future analysis include drill bit analysis with respect to heat transfer and the impact of dissociation of gas hydrate around the wellbore and seafloor stability.

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.

Geothermal gradient drilling, north-central Cascades of Oregon, 1979  

DOE Green Energy (OSTI)

A geothermal gradient drilling program was conducted on the western flank of the north-central Cascade Mountains in Oregon. Six wells were drilled during this program, although in effect seven were drilled, as two wells were drilled at site 3, the second well, however, actually going to a lesser depth than the first. Three of the wells (3, 4, and 5) were drilled in areas which topographically are subject to strong throughflows of ground water. None of these wells reached the regional water table, and all showed essentially isothermal geothermal gradients. The single well which was started essentially at the water table (well 6) shows a linear temperature rise with depth essentially from the top of the well bore. Well No. 2 shows an isothermal gradient down to the level of the regional water table and then shows a linear gradient of about 70/sup 0/C/km from the regional water table to total depth.

Slimhole Drilling, Logging, and Completion Technology - An Update  

DOE Green Energy (OSTI)

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.
