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

Science Journals Connector (OSTI)

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

The effect of the 2010 Gulf oil spill on public attitudes toward offshore oil drilling and wind development  

Science Journals Connector (OSTI)

Abstract In April 2010, the Deepwater Horizon oil well exploded, releasing over four million barrels of oil into the Gulf of Mexico. This paper presents data from two national mail surveys undertaken in 2008 and 2010 that compare public attitudes to both offshore oil drilling and offshore wind development pre- and post-spill. The results show that while there was a drop in support for expanded drilling (from 66% in 2008 to 59% in 2010) the change was not significant. There was, however, a significant decrease in support for offshore drilling among coastal residents. There was a slight, non-significant increase in support for offshore wind development which remained significantly higher than support for offshore oil (80% in 2008 and 82% in 2010). Despite there being no significant change in overall support levels, there was a shift in the strength of feeling regarding offshore oil, with 80% of Americans either less supportive or more opposed to expanded drilling in 2010 than they were in 2008.

Diverter bop system and method for a bottom supported offshore drilling rig  

SciTech Connect

A system and method for installing a fluid flow controller and telescoping spools beneath an offshore bottom supported drilling rig rotary table is disclosed. Upper and lower telescoping spools are provided for initially connecting a Diverter/BOP convertible fluid flow controller between structural casing in the well and a permanent housing beneath the drilling rig rotary table. Clamp means are provided for clamping the rig vent line to an opening in the housing wall of the fluid flow controller during drilling of the borehole through the structural casing in preparation for setting and cementing the conductor casing. In that mode, the system is adapted as a diverter system. After the well is drilled for the conductor casing and the conductor casing is cemented and cut off at its top, a mandrel is fitted at the top of the conductor casing to which the lower end of the lower spool may be connected. The system may be used in this configuration as a diverter system, or after removal of the vent line and connection of a kill line to the housing outlet, the system may be used as a low pressure blowout preventer system.

Evaluating accidents in the offshore drilling of petroleum: Regional picture and reducing impact  

Science Journals Connector (OSTI)

Abstract This study examined several accidents over the last 56 years in the offshore drilling of petroleum. The aim is to examine the situation in relation to jack-ups, drill ships, semi-submersible and platforms and have a better awareness and understanding which may reduce the number of accidents. The materials examined were available published reports and data on exploration and production activities. From 219 accidents recorded the highest was due to blowouts with 46.1%, followed by storms and hurricanes with 15.1% and structural failures with 11.4%. High fatalities occurred at the Funiwa 5 platform in Nigeria with 230, the Piper Alpha platform in the North Sea with 167 and the Keilland semi-submersible in Norway. Other high fatalities were recorded at the Ocean Ranger fire and sinking, Java Sea sinking, Bohai 2 and Bohai 3 fire and sinking. Worker training and discipline must be maintained at a high level. The facilities must be kept sea-worthy and reliable through regular maintenance.

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

Science Journals Connector (OSTI)

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

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

Science Journals Connector (OSTI)

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

Effects of the terra nova offshore oil development on benthic macro-invertebrates over 10 Years of development drilling on the grand Banks of Newfoundland, Canada  

Science Journals Connector (OSTI)

Abstract This paper describes effects of drilling with water and synthetic-based drilling muds on benthic invertebrates over 10 years at the Terra Nova offshore oil development. As such, the paper provides insight on the effects of relatively new synthetic-based drilling muds (SBMs), and makes an important contribution to our understanding of the long-term chronic effects of drilling on benthic communities. The Terra Nova Field is located approximately 350 km offshore on the Grand Banks of Newfoundland (Canada). Sediment and invertebrate samples were collected in 1997 (baseline) prior to drilling, and subsequently in 2000, 2001, 2002, 2004, 2006, 2008 and 2010. Approximately 50 stations were sampled in each year at distances of less than 1 to approximately 20 km from drill centres. Summary benthic invertebrate community measures examined were total abundance, biomass, richness, diversity and multivariate measures of community composition based on non-Metric Dimensional Scaling (nMDS). Decreases in abundance, biomass and richness were noted at one station located nearest (0.14 km) to a drill centre in some EEM (environmental effects monitoring) years. These decreases coincided with higher levels of tracers of drill muds in sediments (barium and >C10-C21 hydrocarbons). Abundances of selected individual taxa were also examined to help interpret responses when project-related effects on summary measures occurred. Enrichment effects on some tolerant taxa (e.g., the polychaete family Phyllodocidae and the bivalve family Tellinidae) and decreased abundances of sensitive taxa (e.g., the polychaete families Orbiniidae and Paraonidae) were detected to within approximately 1 to 2 km from discharge source. Lagged responses three to five years after drilling started were noted for Phyllodocidae and Tellinidae, suggesting chronic or indirect effects. Overall, results of benthic community analyses at Terra Nova indicate that effects on summary measures of community composition were spatially limited but, as seen elsewhere, some taxa were more sensitive to drilling discharges.

Alterations in bottom sediment physical and chemical Characteristics at the terra nova offshore oil development over ten Years of Drilling on the grand Banks of Newfoundland, Canada.  

Science Journals Connector (OSTI)

Abstract This paper describes sediment composition at the Terra Nova offshore oil development. The Terra Nova Field is located on the Grand Banks approximately 350 km southeast of Newfoundland, Canada, at an approximate water depth of 100 m. Surface sediment samples (upper 3 cm) were collected for chemical and particle size analyses at the site pre-development (1997) and in 2000, 2001, 2002, 2004, 2006, 2008 and 2010. Approximately 50 stations have been sampled in each program year, with stations extending from less than 1 km to a maximum of 20 km from source (drill centres) along five gradients, extending to the southeast, southwest, northeast, northwest and east of Terra Nova. Results show that Terra Nova sediments were contaminated with >C10-C21 hydrocarbons and barium - the two main constituents of synthetic-based drilling muds used at the site. Highest levels of contamination occurred within 1 to 2 km from source, consistent with predictions from drill cuttings dispersion modelling. The strength of distance gradients for >C10-C21 hydrocarbons and barium, and overall levels, generally increased as drilling progressed but decreased from 2006 to 2010, coincident with a reduction in drilling. As seen at other offshore oil development sites, metals other than barium, sulphur and sulphide levels were elevated and sediment fines content was higher in the immediate vicinity (less than 0.5 km) of drill centres in some sampling years; but there was no strong evidence of project-related alterations of these variables. Overall, sediment contamination at Terra Nova was spatially limited and only the two major constituents of synthetic-based drilling muds used at the site, >C10-C21 hydrocarbons and barium, showed clear evidence of project-related alternations.

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

SciTech Connect

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

Examination of body burden and taint for Iceland scallop (chlamys islandica) and American plaice (Hippoglossoides platessoides) near the terra nova offshore oil development over ten Years of drilling on the grand Banks of Newfoundland, Canada  

Science Journals Connector (OSTI)

Abstract This paper presents results of analyses of body burdens of metals and hydrocarbons and taste tests for taint in Iceland scallop and American plaice performed as part of the Environmental Effects Monitoring (EEM) program for the Terra Nova offshore oil development (Grand Banks of Newfoundland, Canada). Scallop and plaice were collected in a Study Area located within approximately 1 km of drill centres at Terra Nova and in a Reference Area located approximately 20 km from the development. Samples were collected in 1997 to establish a baseline, and from 2000 to 2010, during drilling periods. Scallop adductor muscle was contaminated with >C10-C21aliphatic hydrocarbons resembling the drilling fluid in the synthetic drilling mud (SBM) used at Terra Nova in 2000, 2002 and 2004, but contamination of adductor muscle was not noted in 2006, 2008 and 2010. The maximum concentration in muscle was 28 mg/kg wet weight, noted in 2002. Scallop viscera was contaminated with hydrocarbons resembling drilling fluid in \\{SBMs\\} near drill centres in all EEM years except 2010. Viscera contamination with >C10-C21 hydrocarbons gradually decreased from a maximum of 150 mg/kg in 2000, to a maximum of 27 mg/kg in 2008; all values were below the laboratory reporting detection limit of 15 mg/kg in 2010. Therefore, evidence from both muscle and viscera indicates a decrease in tissue hydrocarbon contamination in recent years. Barium, another major constituent in drilling muds, has not been noted in scallop adductor muscles at concentrations above the reporting detection limit, but barium was detected in viscera in baseline and EEM years. The maximum concentration of barium in viscera during baseline sampling was 8 mg/kg. The maximum concentration in EEM years (29 mg/kg) was noted in 2000. The maximum concentration in 2010 was 25 mg/kg. The concentration of metals other than barium in scallop tissues was similar between the Terra Nova Study Area and the Reference Area. Hydrocarbons resembling the fluid in SBM were noted in one American plaice liver sample collected near drill centres in 2000. Otherwise, there has been no evidence of project-related metals or hydrocarbon contamination in plaice liver or fillet samples. There has been no evidence of taint (off-taste) for scallop adductor muscle and plaice fillet tissue in baseline or EEM years. Combined with a parallel study on fish bioindicators at Terra Nova that showed that fish health at Terra Nova was similar to that at the Reference Area (Mathieu et al., 2011), these results indicate little to no detectable biological effects on Iceland scallop and American plaice as a result of Terra Nova activities.

HydroPulse Drilling  

SciTech Connect

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

Chapter 3 - Offshore Platforms  

Science Journals Connector (OSTI)

Abstract Modern offshore crude oil and natural gas exploration—the search for likely environments where crude oil and natural gas may exist in the rock formations that are beneath the surface of the waterways of the world. In addition, offshore operations include transporting crude oil and natural gas from their point of production offshore to refineries and plants on land. Very little refining of the crude oil and natural gas is carried out on the production platform. This chapter focuses on exploration, drilling, and production of crude oil and natural gas and the wide range of technologies involved as well as the additional technologies that relate to a marine environment necessary for offshore activities.

Offshore oil and gas: global resource knowledge and technological change  

Science Journals Connector (OSTI)

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

Performance of hydraulic fracturing and matrix acidizing in horizontal wellbores -- Offshore Qatar  

SciTech Connect

Considerable debate in the Middle East has centered upon what was previously felt to be two separate methods of enhancing revenues and daily production; hydraulic fracturing and horizontal drilling. In an effort to maximize return on investment, these two issues have been successfully combined in other areas of the world. In order to establish the suitability of this technology in this area, two horizontal wells with over 3,050m (10,000ft) of lateral section were drilled into the Cretaceous Kharaib formation, overlying the North Field, Offshore Qatar. A massive stimulation program was performed in order to evaluate the most feasible stimulation method from both a technical and economical perspective for further field development considerations.Three propped hydraulic fracturing treatments were performed using 183, 500kg (403, 700lb) of 20/40 mesh sand, and seventeen acid matrix treatments placing over 3,217,250l (850,000gals) of HCL into the lateral sections of both wells. This paper describes the performance, operation and logistical support required to complete this offshore operation with join a minimal time frame. The use of a mobile offshore jack-up platform, whereby a land based fracturing spread was placed onto the deck of a converted drilling rig is described.

Two wells drilled from one surface bore with downhole splitter  

SciTech Connect

A downhole multiwell drilling template, called a downhole splitter, allows two wells to be drilled, cased, and completed from one well bore. After completion, each well can be produced, serviced, and worked over independently of the other. The downhole splitter was successfully field tested in Wyoming. The downhole splitter is suitable for use on offshore platforms, subsea completions, offshore exploitation and delineation wells, inland waters, and onshore in environmentally sensitive areas. It is also ideal for planned multilateral or multivertical completions. The paper describes the downholds splitter and its development, then discusses the field test: casing program, directional procedure, and results.

Calculator program optimizes bit weight, rotary speed, reducing drilling cost  

SciTech Connect

Bit selection, bit weight, and rotary speed have repeatedly proven to be the most important and commonly overlooked alterable factors which control penetration rate, footage, and overall drilling cost. This is particularly true in offshore operations where drilling costs are highest and the greatest cost savings stand to be achieved through implementation of proven optimization techniques. The myth that bit weights and rotary speeds cannot be optimized in directional holes has hindered the industry from using this virtually cost-free method for reducing drilling cost. The use of optimized bit weights and rotary speeds in conjunction with minimum cost bit programs based on cost per foot analysis of previous bit runs in the area was implemented on a five-well platform in the Grand Isle Block 20 field, offshore Louisiana. Each of the directional wells was drilled substantially faster and cheaper than the discovery well, which was a straight hole. Average reductions in footage cost of 31.3%, based on daily operating cost of $30,000/day, and increase in average daily footage drilled of 45.2% were effected by ''collectively optimizing'' drilling performance. The ''Optimizer'' program is an HP-41CV adaptation of the Bourgoyne and Young drilling model. It was used to calculate the optimum bit weights and rotary speeds based on field drilling tests; historical bit and bearing wear data; and current operating conditions, cost, and constraints.

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.

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.

Offshore wind energy systems  

Science Journals Connector (OSTI)

Wind energy systems deployed in the shallow but windy waters of the southern North Sea have the potential to provide more than 20% of UK electricity needs. With existing experience of windmills, and of aircraft and offshore structures, such wind energy systems could be developed within a relatively short timescale. A preliminary assessment of the economics of offshore wind energy systems is encouraging.

Offshore wind metadata management  

Science Journals Connector (OSTI)

Offshore wind energy is gaining more and more attention from industry and research community due to its high potential in producing green energy and lowering price on electricity consumption. However, offshore wind is facing many challenges, and hence it is still expensive to install in large scale. It therefore needs to be considered from different aspects of technologies in order to overcome these challenges. One of the problems of the offshore wind is that information comes from different sources with diversity in types and format. Besides, there are existing wind databases that should be utilised in order to enrich the knowledge base of the wind domain. This paper describes an approach to managing offshore wind metadata effectively using semantic technologies. An offshore wind ontology has been developed. The semantic gap between the developed ontology and the relational database is investigated. A prototype system has been developed to demonstrate the use of the ontology.

Well drilling apparatus  

SciTech Connect

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

Supporting technology for enhanced recovery, Annex V: evaluate application of recently developed techniques in the areas of drilling, coring, and telemetry. Venezuela-MEM/USA-DOE fossil-energy report V-1  

SciTech Connect

The Agreement between the United States and Venezuela was designed to further energy research and development in six areas. This report focuses on Annex V - Drilling, Coring, and Telemetry as supporting technology for enhanced oil recovery projects in the United States and Venezuela. Annex V consists of 18 tasks to perform these three projects. This report completes the work for Annex V. Energy research and development in the area of Enhanced Oil Recovery has as its goal the more efficient and complete production of the third crop of oil. Methods and techniques must be developed to assist in the implementation of EOR projects. Technology development that reduces costs and provides better reservoir information often has a direct impact on the economic viability of EOR projects and Annex V addresses these areas. Each of the three areas covered by Annex V are separate entities and are presented in this report as different sections. Each has its own Abstract. The drilling and coring tests were highly successful but only a limited amount of work was necessary in the Telemetry area because a field test was not feasible.

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.

Drilling operations change gear  

SciTech Connect

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

Chapter 4 Drilling Engineering  

Science Journals Connector (OSTI)

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

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.

Focus on rotary drill rigs  

SciTech Connect

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

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.

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".

Blast furnace taphole drill  

SciTech Connect

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

HYDRATE CORE DRILLING TESTS  

SciTech Connect

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

Proper planning improves flow drilling  

SciTech Connect

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

Electrification of offshore petroleum installations with offshore wind integration  

Science Journals Connector (OSTI)

Electric power supply to oil and gas platforms is conventionally provided by gas turbines located on the platforms. As these gas turbines emit considerable amounts of CO2 and NOx, it is desirable to find alternative solutions. One alternative is to feed the platforms from the onshore power system via subsea power cables, which already have been implemented on some platforms in the Norwegian part of the North Sea. The paper studies a cluster of petroleum installations in this geographic area, connected to the Norwegian onshore power system through an HVDC voltage link. In the study, an offshore wind farm is also connected to the offshore AC power system. The main focus is investigation of transient stability in the offshore power system, and several fault cases have been studied for different levels of wind power generation. Simulations show that faults on the offshore converter platform can be critical due to the dependency of the reactive power delivered by the HVDC link to the offshore AC system. However, it is shown that local wind power production matching the offshore power demand will improve both voltage- and frequency-stability. Further on, it is indicated that offshore reactive power injections or alternative wind farm control topologies could improve voltage stability offshore.

Towers for Offshore Wind Turbines  

Science Journals Connector (OSTI)

Increasing energy demand coupled with pollution free production of energy has found a viable solution in wind energy. Land based windmills have been utilized for power generation for more than two thousand years. In modern times wind generated power has become popular in many countries. Offshore wind turbines are being used in a number of countries to tap the energy from wind over the oceans and convert to electric energy. The advantages of offshore wind turbines as compared to land are that offshore winds flow at higher speed than onshore winds and the more available space. In some land based settings for better efficiency turbines are separated as much as 10 rotor diameters from each other. In offshore applications where only two wind directions are likely to predominate the distances between the turbines arranged in a line can be shortened to as little as two or four rotor diameters. Today more than a dozen offshore European wind facilities with turbine ratings of 450 kw to 3.6 MW exist offshore in very shallow waters of 5 to 12 m. Compared to onshore wind turbines offshore wind turbines are bigger and the tower height in offshore are in the range of 60 to 80 m. The water depths in oceans where offshore turbines can be located are within 30 m. However as the distance from land increases the costs of building and maintaining the turbines and transmitting the power back to shore also increase sharply. The objective of this paper is to review the parameters of design for the maximum efficiency of offshore wind turbines and to develop types offshore towers to support the wind turbines. The methodology of design of offshore towers to support the wind turbine would be given and the environmental loads for the design of the towers would be calculated for specific cases. The marine corrosion on the towers and the methods to control the corrosion also would be briefly presented. As the wind speeds tend to increase with distance from the shore turbines build father offshore will be able to capture more wind energy. Currently two types of towers are considered. Cylindrical tubular structures and truss type structures. But truss type structures have less weight and flexibility in design. The construction of the offshore towers to harness the wind energy is also presented. The results will include the calculation of wind and wave forces on the tower and the design details for the tower.

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.

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

SciTech Connect

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

A Monte Carlo approach to forecasting the demand for offshore supply vessels  

Science Journals Connector (OSTI)

In the near future, the demand for offshore supply vessels in Brazil will be driven by the activities induced by the bids carried out by the regulatory agency, ANP. The likely tendency is to increase the number of bids and consequently, the demand for vessels in the coming years. The proposed model consists of a Monte Carlo simulation of the offshore oil exploration and production projects. The model considers some parameters that aim at capturing the effect of the operators patterns, water depth, duration of seismic research and exploration and drilling work, number of wells, geographic location and geological risk. An estimate is obtained for the additional offshore supply vessels demand, for the period of 2006-2008.

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

Science Journals Connector (OSTI)

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

U.S. drilling: Solid reasons for optimism  

SciTech Connect

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

Relating horsepower to drilling productivity  

SciTech Connect

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

Scour around an offshore platform  

SciTech Connect

On the whole offshore scour has proved less of a problem than one might fear without being overly pessimistic, based on experience from other hydrotechnical works. The offshore setting, the environment as well as the structures, was simply beyond the reach to which conventional concepts and models could be safely extrapolated. The essentially empirical art of sediment engineering had to acquire a new empirical base. Today we know a lot more than we did a decade ago, however, our knowledge is still fragmentary, and we have no unifying theory yet.

Drilling Waste Management Fact Sheet: Discharge to Ocean  

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

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

Application of horizontal drilling to tight gas reservoirs  

SciTech Connect

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

Drilling fluid technology for horizontal wells to protect the formations in unconsolidated sandstone heavy oil reservoirs  

Science Journals Connector (OSTI)

Major factors that cause damage in drilling in unconsolidated sandstone heavy oil reservoirs include: invasion of solids in drilling fluid, incompatibility between the liquid phase of drilling fluid and crude oil, and hydration and expansion of reservoir clay minerals. Therefore, a solid-free weak gel drilling fluid system for horizontal wells to protect the formations was developed that contains seawater + 0.1%–0.2% NaOH + 0.2% Na2CO3+ 0.7% VIS + 2.0% FLO + 2.0% JLX, weighed with \\{KCl\\} or sodium formate. The drilling fluid system has unique rheological properties, temporally independent gel strength, and excellent lubricating and inhibition performance. It is compatible with formation fluids, it not only meets the needs of horizontal well drilling, but also effectively protects the reservoir. The technique is well performed in tens of horizontal wells in offshore oilfields, such as WC13-1, BZ34-1, NP35-2, and BZ25-1 oilfields.

1982 geothermal well drilling summary  

SciTech Connect

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

National Offshore Wind Energy Grid Interconnection Study  

SciTech Connect

The National Offshore Wind Energy Grid Interconnection Study (NOWEGIS) considers the availability and potential impacts of interconnecting large amounts of offshore wind energy into the transmission system of the lower 48 contiguous United States. A total of 54GW of offshore wind was assumed to be the target for the analyses conducted. A variety of issues are considered including: the anticipated staging of offshore wind; the offshore wind resource availability; offshore wind energy power production profiles; offshore wind variability; present and potential technologies for collection and delivery of offshore wind energy to the onshore grid; potential impacts to existing utility systems most likely to receive large amounts of offshore wind; and regulatory influences on offshore wind development. The technologies considered the reliability of various high-voltage ac (HVAC) and high-voltage dc (HVDC) technology options and configurations. The utility system impacts of GW-scale integration of offshore wind are considered from an operational steady-state perspective and from a regional and national production cost perspective.

Geology of the Douala basin, offshore Cameroon, West Africa  

SciTech Connect

The Douala basin is predominantly an offshore basin extending from the Cameroon volcanic line in the north to the Corisco arch in the south near the Equatorial Guinea-Gabon border. The basin lies wholly within the territorial borders of Cameroon and Equatorial Guinea. The Douala basin is one of a series of divergent margin basins occurring along the southwest African coastline resulting from the rifting of Africa from South America. Continental rifting in the Doula basin was initiated at least by Aptian-Albian time and possibly as early as Jurassic. The rift stage persisted until Albian time when the onset of drifting occurred. The sedimentary section in the basin has a maximum thickness of 8-10 km, based on exploration drilling and gravity and magnetics modeling. The synrift section consists of Aptian-Albian sands and shales, deposited primarily as submarine fans, fan-deltas, and turbidite deposits. These are overlain by salt, thought to be equivalent to the Ezagna salt of Aptian age in the Gabon basin to the south. The synrift section is separated from the overlying postrift shale sequence of Late Cretaceous and Tertiary age by a major late Albian unconformity. The Douala basin has been explored for hydrocarbons intermittently over the last 25 years. Results show a distinct tendency for gas-proneness. The largest field recorded to date is the Sanaga Sud gas field, discovered in 1979, offshore, near the coastal city of Kribi.

Forecast of geothermal drilling activity  

SciTech Connect

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

Tool Wear in Friction Drilling  

SciTech Connect

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

Vibratory Drilling of Oil Wells  

Science Journals Connector (OSTI)

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

AN ADVANCED FRACTURE CHARACTERIZATION AND WELL PATH NAVIGATION SYSTEM FOR EFFECTIVE RE-DEVELOPMENT AND ENHANCEMENT OF ULTIMATE RECOVERY FROM THE COMPLEX MONTEREY RESERVOIR OF SOUTH ELLWOOD FIELD, OFFSHORE CALIFORNIA  

SciTech Connect

Venoco Inc, intends to re-develop the Monterey Formation, a Class III basin reservoir, at South Ellwood Field, Offshore Santa Barbara, California. Well productivity in this field varies significantly. Cumulative Monterey production for individual wells has ranged from 260 STB to 8,700,000 STB. Productivity is primarily affected by how well the well path connects with the local fracture system and the degree of aquifer support. Cumulative oil recovery to date is a small percentage of the original oil in place. To embark upon successful re-development and to optimize reservoir management, Venoco intends to investigate, map and characterize field fracture patterns and the reservoir conduit system. State of the art borehole imaging technologies including FMI, dipole sonic and cross-well seismic, interference tests and production logs will be employed to characterize fractures and micro faults. These data along with the existing database will be used for construction of a novel geologic model of the fracture network. Development of an innovative fracture network reservoir simulator is proposed to monitor and manage the aquifer's role in pressure maintenance and water production. The new fracture simulation model will be used for both planning optimal paths for new wells and improving ultimate recovery. In the second phase of this project, the model will be used for the design of a pilot program for downhole water re- injection into the aquifer simultaneously with oil production. Downhole water separation units attached to electric submersible pumps will be used to minimize surface fluid handling thereby improving recoveries per well and field economics while maintaining aquifer support. In cooperation with the DOE, results of the field studies as well as the new models developed and the fracture database will be shared with other operators. Numerous fields producing from the Monterey and analogous fractured reservoirs both onshore and offshore will benefit from the methodologies developed in this project. This report presents a summary of all technical work conducted during the fourth quarter of Budget Period II.

World offshore energy loss statistics  

Science Journals Connector (OSTI)

Offshore operations present a unique set of environmental conditions and adverse exposure not observed in a land environment taking place in a confined space in a hostile environment under the constant danger of catastrophe and loss. It is possible to engineer some risks to a very low threshold of probability, but losses and unforeseen events can never be entirely eliminated because of cost considerations, the human factor, and environmental uncertainty. Risk events occur infrequently but have the potential of generating large losses, as evident by the 2005 hurricane season in the Gulf of Mexico, which was the most destructive and costliest natural disaster in the history of offshore production. The purpose of this paper is to provide a statistical assessment of energy losses in offshore basins using the Willis Energy Loss database. A description of the loss categories and causes of property damage are provided, followed by a statistical assessment of damage and loss broken out by region, cause, and loss category for the time horizon 1970–2004. The impact of the 2004–2005 hurricane season in the Gulf of Mexico is summarized.

Downhole Temperature Prediction for Drilling Geothermal Wells  

SciTech Connect

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

An Advanced Fracture Characterization and Well Path Navigation System for Effective Re-Development and Enhancement of Ultimate Recovery from the Complex Monterey Reservoir of South Ellwood Field, Offshore California  

SciTech Connect

Venoco Inc, intends to re-develop the Monterey Formation, a Class III basin reservoir, at South Ellwood Field, Offshore Santa Barbara, California. Well productivity in this field varies significantly. Cumulative Monterey production for individual wells has ranged from 260 STB to over 10,000,000 STB. Productivity is primarily affected by how well the well path connects with the local fracture system and the degree of aquifer support. Cumulative oil recovery to date is a small percentage of the original oil in place. To embark upon successful re-development and to optimize reservoir management, Venoco intended to investigate, map and characterize field fracture patterns and the reservoir conduit system. In the first phase of the project, state of the art borehole imaging technologies including FMI, dipole sonic, interference tests and production logs were employed to characterize fractures and micro faults. These data along with the existing database were used in the construction of a new geologic model of the fracture network. An innovative fracture network reservoir simulator was developed to better understand and manage the aquifer’s role in pressure maintenance and water production. In the second phase of this project, simulation models were used to plan the redevelopment of the field using high angle wells. Correct placement of the wells is critical to intersect the best-developed fracture zones and to avoid producing large volumes of water from the water leg. Particula r attention was paid to those areas of the field that have not been adequately developed with the existing producers. In cooperation with the DOE and the PTTC, the new data and the new fracture simulation model were shared with other operators. Numerous fields producing from the Monterey and analogous fractured reservoirs both onshore and offshore will benefit from the methodologies developed in this project. This report presents a summary of all technical work conducted during Budget Periods I and II. Venoco elected to terminate the project after Budget Period II and not to proceed with the activities planned for Budget Period III.

Shallow Drilling In The Salton Sea Region, The Thermal Anomaly  

SciTech Connect

During two shallow thermal drilling programs, thermal measurements were obtained in 56 shallow (76.2 m) and one intermediate (457.3 m) depth holes located both onshore and offshore along the southern margin of the Salton Sea in the Imperial Valley, California. These data complete the surficial coverage of the thermal anomaly, revealing the shape and lateral extent of the hydrothermal system. The thermal data show the region of high thermal gradients to extend only a short distance offshore to the north of the Quaternary volcanic domes which are exposed along the southern shore of the Salton Sea. The thermal anomaly has an arcuate shape, about 4 km wide and 12 km long. Across the center of the anomaly, the transition zone between locations exhibiting high thermal gradients and those exhibiting regional thermal gradients is quite narrow. Thermal gradients rise from near regional (0.09 C/m) to extreme (0.83 C/m) in only 2.4 km. The heat flow in the central part of the anomaly is >600 mW/m{sup 2} and in some areas exceeds 1200 mW/m{sup 2}. The shape of the thermal anomaly is asymmetric with respect to the line of volcanoes previously thought to represent the center of the field, with its center line offset south of the volcanic buttes. There is no broad thermal anomaly associated with the magnetic high that extends offshore to the northeast from the volcanic domes. These observations of the thermal anomaly provide important constraints for models of the circulation of the hydrothermal system. Thermal budgets based on a simple model for this hydrothermal system indicate that the heat influx rate for local ''hot spots'' in the region may be large enough to account for the rate of heat flux from the entire Salton Trough.

Microhole Drilling Tractor Technology Development  

SciTech Connect

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

Optical coherence tomography guided dental drill  

DOE Patents (OSTI)

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

Chemical Speciation of Chromium in Drilling Muds  

SciTech Connect

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

Chapter 2 Offshore Wind Power Stations  

Science Journals Connector (OSTI)

Publisher Summary This chapter presents the historical background and development of offshore wind power stations. As early as 1890, windmills were put to work to produce electricity and more than 50,000 mills were in use in the United States alone in the twenties and thirties. Their decline was precipitated by the Rural Electrification Program. According to the San Francisco based Transaction Energy Projects Institute, offshore windmills could generate all the electrical power needed by northern California. Ocean winds have of course provided energy to windmills for centuries. In 1976, a study was commissioned by the (U.S.) Energy Research and Development Administration to ascertain and assess the economic value of offshore multi units aiming at identification and classification of area offshore types, assessing utility requirements for offshore power systems. It includes developing installation concepts including various floating and bottom-mounted designs, assessing current WECS (wind energy converter systems) for use in offshore environments, assessing various electric transmission and hydrogen delivery concepts, and performing an economic assessment, providing tradeoffs for variables such as distance offshore, climate, bottom and wave characteristics and average wave velocities. It is suggested that high wind velocity sites must be identified because the energy flow increases with the cube of the wind velocity; the kinetic energy of the wind passing through the area swept by the blades of a turbine is the energy available to that wind turbine. An average wind speed distribution is required.

Expanders do payouts offshore North Sea  

SciTech Connect

Rich associated gas may be beneficially processed offshore, to yield high value condensate to be spiked into the crude, whilst still producing gas with an acceptable nett calorific value. Actual turbo expander operating experience on the Occidental Piper North Sea Platform has demonstrated that expanders are reliable offshore. This paper, describes both the process and mechanical aspects that affect the choice of an expander system for an offshore application. For a given typical rich associated gas, three process options are compared, Joule-Thompson expansion, external refrigeration and a turbo expander system. The process study illustrates that a turbo expander system is comparable for the offshore situation with the other two options. The paper also describes the mechanical features that should be incorporated into the specification of an expander for use on a platform topsides.

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

Reforming Brazil?s offshore oil and gas safety regulatory framework: Lessons from Norway, the United Kingdom and the United States  

Science Journals Connector (OSTI)

Abstract We propose reforming the Brazilian regulatory safety framework (BRSF) for offshore oil and gas production and drilling operations. Brazil has emerged as a leading offshore producer with extensive proven reserves yet to be exploited. However, the BRSF has not been updated since 2007, and there are now major concerns about the industry?s safety, particularly after the BP Deepwater Horizon accident, along with the technical challenges due to extreme conditions under which Brazil?s resources are located. Drawing on experiences from three leading offshore oil and gas producers (Norway, the UK, and the US), we recommend the adoption of three best practices: the UK?s ‘safety case’ approach (where operators are expected to provide convincing and valid arguments that a system is sufficiently safe for a given application in a specific environment), Norway?s ‘barrier management’ (evidence that there are at least two tested and independent barriers to avoid accidents) and greater investment in safety research and development, as suggested by the US?s National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling. We discuss implications for policy reform and how best practices can be applied within the Brazilian context.

Chapter 6 - Offshore Structural Analysis  

Science Journals Connector (OSTI)

Publisher Summary This chapter discusses the primary considerations that the design engineer should bear in mind during the initial design and subsequent structural analysis. The designer is faced with a large number of rules, codes, standards, and specifications describing the general policy for structural systems and the detailed design of structural components, which includes government requirements, certification/classification authorities, and other technical documents. The notation “Structures” refers to all types of marine units ranging from floating ship-shaped vessels to bottom founded platforms. Emphasis has been placed on ship-shaped structures. Consideration is also given to column-supported structures, e.g., semi-submersibles, tension leg platforms, spars, and mooring buoys, etc., and also to steel bottom founded offshore structures, such as fixed steel jackets. The main output of the planning process is a “Design Basis,” describing the criteria and a “Design Brief,” describing the procedure to be followed and software to be used. This chapter discusses the finite element method, which is a powerful computational tool that has been widely used in the design of complex marine structures over the decades. This chapter gives a general overview for the design of marine structures using a finite element modeling technique. It also addresses structural modeling defined by industry codes for fixed platforms and floating production installations. Throughout this chapter, emphasis is placed on the design process where the finite element analysis will be employed.

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.

MIMO Control during Oil Well Drilling  

Science Journals Connector (OSTI)

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

Preliminary report on shallow research drilling in the Salton Sea region  

SciTech Connect

During two shallow thermal drilling programs, thermal measurements were obtained in 56 shallow (76.2 m) and one intermediate (457.3 m) depth holes located both onshore and offshore along the southern margin of the Salton Sea in the Imperial Valley, California. These data complete the surficial coverage of the thermal anomaly, revealing the shape and lateral extent of the hydrothermal system. The thermal data show the region of high thermal gradients to extend only a short distance offshore to the north of the Quaternary volcanic domes which are exposed along the southern shore of the Salton Sea. The central thermal anomaly has an arcuate shape, about 4 km wide and 12 km long. Across the center of the anomaly, the transition zone between locations exhibiting high thermal gradients and those exhibiting regional thermal gradients is quite narrow. Thermal gradients rise from near regional (0.09/degree/C/m) to extreme (0.83/degree/C/m) in only 2.4 km. The heat flow in the central part of the anomaly is greater than 600 mW/m/sup 2/ and in some areas exceeds 1200 mW/m/sup 2/. The shape of the thermal anomaly is asymmetric with respect to the line of volcanoes previously thought to represent the center of the field, with its center line offset south of the volcanic buttes. There is no broad thermal anomaly associated with the magnetic high that extends offshore to the northeast from the volcanic domes.

Laser Drilling - Drilling with the Power of Light  

SciTech Connect

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

Lake Michigan Offshore Wind Feasibility Assessment  

SciTech Connect

The purpose of this project was to conduct the first comprehensive offshore wind assessment over Lake Michigan and to advance the body of knowledge needed to support future commercial wind energy development on the Great Lakes. The project involved evaluation and selection of emerging wind measurement technology and the permitting, installation and operation of the first mid-lake wind assessment meteorological (MET) facilities in Michigan’s Great Lakes. In addition, the project provided the first opportunity to deploy and field test floating LIDAR and Laser Wind Sensor (LWS) technology, and important research related equipment key to the sitting and permitting of future offshore wind energy development in accordance with public participation guidelines established by the Michigan Great Lakes Wind Council (GLOW). The project created opportunities for public dialogue and community education about offshore wind resource management and continued the dialogue to foster Great Lake wind resource utilization consistent with the focus of the GLOW Council. The technology proved to be effective, affordable, mobile, and the methods of data measurement accurate. The public benefited from a substantial increase in knowledge of the wind resources over Lake Michigan and gained insights about the potential environmental impacts of offshore wind turbine placements in the future. The unique first ever hub height wind resource assessment using LWS technology over water and development of related research data along with the permitting, sitting, and deployment of the WindSentinel MET buoy has captured public attention and has helped to increase awareness of the potential of future offshore wind energy development on the Great Lakes. Specifically, this project supported the acquisition and operation of a WindSentinel (WS) MET wind assessment buoy, and associated research for 549 days over multiple years at three locations on Lake Michigan. Four research objectives were defined for the project including to: 1) test and validate floating LIDAR technology; 2) collect and access offshore wind data; 3) detect and measure bird and bat activity over Lake Michigan; 4) conduct an over water sound propagation study; 5) prepare and offer a college course on offshore energy, and; 6) collect other environmental, bathometric, and atmospheric data. Desk-top research was performed to select anchorage sites and to secure permits to deploy the buoy. The project also collected and analyzed data essential to wind industry investment decision-making including: deploying highly mobile floating equipment to gather offshore wind data; correlating offshore wind data with conventional on-shore MET tower data; and performing studies that can contribute to the advancement and deployment of offshore wind technologies. Related activities included: • Siting, permitting, and deploying an offshore floating MET facility; • Validating the accuracy of floating LWS using near shoreline cup anemometer MET instruments; • Assessment of laser pulse technology (LIDAR) capability to establish hub height measurement of wind conditions at multiple locations on Lake Michigan; • Utilizing an extended-season (9-10 month) strategy to collect hub height wind data and weather conditions on Lake Michigan; • Investigation of technology best suited for wireless data transmission from distant offshore structures; • Conducting field-validated sound propagation study for a hypothetical offshore wind farm from shoreline locations; • Identifying the presence or absence of bird and bat species near wind assessment facilities; • Identifying the presence or absence of benthic and pelagic species near wind assessment facilities; All proposed project activities were completed with the following major findings: • Floating Laser Wind Sensors are capable of high quality measurement and recordings of wind resources. The WindSentinel presented no significant operational or statistical limitations in recording wind data technology at a at a high confidence level as compared to traditional an

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

Science Journals Connector (OSTI)

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

Comparative analysis of core drilling and rotary drilling in volcanic terrane  

SciTech Connect

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

Innovative technology summary report: Cryogenic drilling  

SciTech Connect

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

Federal Environmental Regulations Impacting Hydrocarbon Exploration, Drilling, and Production Operations  

SciTech Connect

Waste handling and disposal from hydrocarbon exploration, drilling, and production are regulated by the US Environmental Protection Agency (EPA) through federal and state regulations and/or through implementation of federal regulations. Some wastes generated in these operations are exempt under the Resource Conservation and Recovery Act (RCRA) but are not exempt under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Superfund Amendments and Reauthorization Act (SARA), and other federal environmental laws. Exempt wastes remain exempt only if they are not mixed with hazardous wastes or hazardous substances. Once mixture occurs, the waste must be disposed as a hazardous material in an approved hazardous waste disposal facility. Before the Clean Air Act as amended in 1990, air emissions from production, storage, steam generation, and compression facilities associated with hydrocarbon exploration, drilling, and production industry were not regulated. A critical proposed regulatory change which will significantly effect Class II injection wells for disposal of produced brine and injection for enhanced oil recovery is imminent. Federal regulations affecting hydrocarbon exploration, drilling and production, proposed EPA regulatory changes, and a recent significant US Court of Appeals decision are covered in this report. It appears that this industry will, in the future, fall under more stringent environmental regulations leading to increased costs for operators.

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

SciTech Connect

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

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.

Strategies and technologies in offshore farming  

Science Journals Connector (OSTI)

A more restrictive attitude to inshore farming, in addition to positive biological findings among offshore farmed fish, have increased the demand for suitable offshore fish farming cages/systems. To develop such a cage/system, the requirements of the fish, the fish farmer, the insurance companies, the authorities and the moorings must be considered. The existing offshore concepts can be classified into: (1) simple flexible one-net bag cages; (2) integrated stiff semi-submersible one-net bag constructions; (3) simple stiff poly-net bag cages; (4) integrated stiff poly-net bag constructions; (5) submersible and submerged cages. An example from each group is described. The Bridgestone cage and the Farmocean system, the only offshore concepts that have been in commercial use for some years, are compared with respect to strength and management. The other concepts are evaluated in various parts. A suitable offshore concept should, in general, consist of a stable, strong and safe platform that should be easy and safe to tow, moor and board. It should allow a proper attachment of the net bag (preferably round, ?15 m deep and 5000 m3 in volume), and guarantee its strength and shape during all weather conditions. The fish should be fed by means of a computer-controlled automatic feeder. Faster growth, lowered mortality and reduced visceral fat content are reported among offshore farmed fish compared with those farmed inshore. A lower degree of self-pollution will also be a consequence of moving larger and deeper cages/systems offshore. The tentative rules for the type approval of floating fish farming units that have been presented by “Det norske Veritas” (DnV) in Norway will be positive for the fish farming business if it starts to be valid and cover the rest of the fish farming countries. Despite the higher investment required for the offshore cages/systems, it has been indicated that there is a better economic result and that the cost of producing 1 kg of fish is lower than in conventional fish farms. As the single-net bag concept represents a lower risk for the fish farmer, insurance company and veterinary authority, it will probably be the preferred concept.

Lateral Drilling and Completion Technologies for Shallow-Shelf Carbonates of the Red River and Ratcliffe Formations, Williston Basin  

SciTech Connect

Luff Exploration Company (LEC) focused on involvement in technologies being developed utilizing horizontal drilling concepts to enhance oil- well productivity starting in 1992. Initial efforts were directed toward high-pressure lateral jetting techniques to be applied in existing vertical wells. After involvement in several failed field attempts with jetting technologies, emphasis shifted to application of emerging technologies for drilling short-radius laterals in existing wellbores and medium-radius technologies in new wells. These lateral drilling technologies were applied in the Mississippi Ratcliffe and Ordovician Red River formations at depths of 2590 to 2890 m (8500 to 9500 ft) in Richland Co., MT; Bowman Co., ND; and Harding Co., SD.

SciTech Connect

This environmental assessment consists of an evaluation of the ecological and indirect human health impacts for the discharge of cuttings contaminated with synthetic-based drilling fluids (SBFs) with respect to discharges to water. In addition, this document describes the environmental characteristics of SBF drilling wastes (e.g., toxicity, bioaccumulation, biodegradation), the types of anticipated impacts, and the pollutant modeling results for water column concentrations, pore water concentrations, and human health effects via consumption of affected seafood. The geographic areas considered under this rule are those where EPA knows SBFs are currently used and those where EPA projects SBFs will be used as a result of the SBF Effluent Guidelines. This includes the Gulf of Mexico, offshore California, and Cook Inlet, Alaska.

Attenuation of sound waves in drill strings  

Science Journals Connector (OSTI)

During drilling of deep wells digital data are often transmitted from sensors located near the drill bit to the surface. Development of a new communication system with increased data capacity is of paramount importance to the drilling industry. Since steel drill strings are used transmission of these data by elastic carrier waves traveling within the drill pipe is possible but the potential communication range is uncertain. The problem is complicated by the presence of heavy?threaded tool joints every 10 m which form a periodic structure and produce classical patterns of passbands and stop bands in the wave spectra. In this article field measurements of the attenuation characteristics of a drill string in the Long Valley Scientific Well in Mammoth Lakes California are presented. Wave propagation distances approach 2 km. A theoretical model is discussed which predicts the location width and attenuation of the passbands. Mode conversion between extensional and bending waves and spurious reflections due to deviations in the periodic spacings of the tool joints are believed to be the sources of this attenuation. It is estimated that attenuation levels can be dramatically reduced by rearranging the individual pipes in the drill string according to length.

Development and Testing of Insulated Drill Pipe  

SciTech Connect

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.

Bakken shale typifies horizontal drilling success  

SciTech Connect

Given the favorable production response that has been obtained from horizontal drilling in vertical- fractured reservoirs such as the Bakken shale and, more recently, the Austin chalk, industry interest in this technology has mushroomed in the U.S. Indeed, it is difficult to find a good-sized oil company these days that is not involved in a horizontal drilling project or is giving it serious consideration. In response to growing evidence of successful field applications, the realization is dawning on the investment community that horizontal drilling represents a significant technological development with positive implications for both the exploration and production business, and the oilfield services industry.

Visual impact assessment of offshore wind farms and prior experience  

Science Journals Connector (OSTI)

Energy planners have shifted their attention towards offshore wind power generation and the decision is supported by the public in general, which in the literature has a positive attitude towards offshore wind generation. However, globally only a few offshore wind farms are operating. As more wind farms start operating and more people become experienced with especially the visual impacts from offshore wind farms, the public positive attitude could change if the experienced impacts are different from the initially perceived visual interference. Using a binary logit model, the present paper investigates the relation between different levels of prior experience with visual disamenities from offshore wind farms and perception of visual impacts from offshore wind farms. The differences in prior experience are systematically controlled for sampling respondents living in the areas close to the large scale offshore wind farms Nysted and Horns Rev and by sampling the a group of respondents representing the Danish population, which has little experience with offshore wind farms. Compared to previous results in the literature, the present paper finds that perception of wind power generation is influenced by prior experience. More specifically, the results show that people with experience from offshore wind farms located far from the coast have a significant more positive perception of the visual impacts from offshore wind farms than people with experience from wind farms located closer to the coast. These results are noteworthy on two levels. First of all, the results show that perceptions of offshore wind generation are systematically significantly influenced by prior experience with offshore wind farms. Secondly, and in a policy context, the results indicate that the future acceptance of future offshore wind farms is not independent of the location of existing and new offshore wind farms. This poses for caution in relation to locating offshore wind farms too close to the coast.

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

Marine bearing for a downhole drilling apparatus  

SciTech Connect

A bearing supports a rotatable shaft in a fluid environment. The bearing can be utilized to support a drive shaft connected to a drill bit in a downhole drilling apparatus. The drive shaft extends through a housing in which drilling fluid is flowing. Preferably, the bearing includes an inner elastomeric sleeve and an outer rigid sleeve attached to the interior side wall of the housing. The drive shaft has a wear sleeve attached for rotation therewith. The wear sleeve is rotatably received in the bearing inner sleeve. The inner sleeve is relatively short as compared with the drive shaft and absorbs radial loads imposed on the drive shaft. The bearing is lubricated by a portion of the drilling fluid in the housing which flows between the exterior side wall of the wear sleeve and the interior side wall of the inner sleeve.

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.

Repair welding influence on offshore pipelines residual stress fields: An experimental study  

Science Journals Connector (OSTI)

Abstract Repair welds, are frequently used in steel structures either to remedy initial fabrication defects, or to rectify in-service degradations of the components. Some previous investigations indicated that repair welding is likely to pose adverse effects on the long-term integrity of the structure exposed to high pressure and temperature actions. It is believed that high residual stresses, associated with the repair process, most probably play an important role in many of subsequent failures. Repair welds might aggravate the size, magnitude and distribution of the tensile residual stresses in the weldments. These adversely affect the component structural integrity and remaining life. So far, no generally accepted guideline is available to provide reliable evaluations on the possible side effects from the repair welding in offshore oil/gas pipelines. This paper reports the result of residual stress measurement on single/double and partial/full repair welds in offshore pipelines. The semi destructive blind hole drilling and destructive sectioning methods have been employed to measure the residual stress fields in each case. In general, the results of the two measurement methods are in reasonable agreement. Residual stresses which are caused by full and partial repairs in the studied samples slightly increased the residual stress distribution when compared to the as-welded condition. Repetition of repair welding in same area influenced the residual stresses' magnitude and distribution especially in areas close to the weld centre line.

Feasibility study of offshore wind turbine substructures for southwest offshore wind farm project in Korea  

Science Journals Connector (OSTI)

Abstract Korea has huge potential for offshore wind energy and the first Korean offshore wind farm has been initiated off the southwest coast. With increasing water depth, different substructures of the offshore wind turbine, such as the jacket and multipile, are the increasing focus of attention because they appear to be cost-effective. However, these substructures are still in the early stages of development in the offshore wind industry. The aim of the present study was to design a suitable substructure, such as a jacket or multipile, to support a 5 MW wind turbine in 33 m deep water for the Korean Southwest Offshore Wind Farm. This study also aimed to compare the dynamic responses of different substructures including the monopile, jacket and multipile and evaluate their feasibility. We therefore performed an eigenanalysis and a coupled aero-hydro-servo-elastic simulation under deterministic and stochastic conditions in the environmental conditions in Korea. The results showed that the designed jacket and multipile substructures, together with the modified monopile, were well located at soft–stiff intervals, where most modern utility-scale wind turbine support structures are designed. The dynamic responses of the different substructures showed that of the three substructures, the performance of the jacket was very good. In addition, considering the simple configuration of the multipile, which results in lower manufacturing cost, this substructure can provide another possible solution for Korean’s first offshore wind farm. This study provides knowledge that can be applied for the deployment of large-scale offshore wind turbines in intermediate water depths in Korea.

Laser Drilling - Drilling with the Power of Light  

SciTech Connect

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

Potential climatic impacts and reliability of large-scale offshore wind farms  

Science Journals Connector (OSTI)

The vast availability of wind power has fueled substantial interest in this renewable energy source as a potential near-zero greenhouse gas emission technology for meeting future world energy needs while addressing the climate change issue. However, in order to provide even a fraction of the estimated future energy needs, a large-scale deployment of wind turbines (several million) is required. The consequent environmental impacts, and the inherent reliability of such a large-scale usage of intermittent wind power would have to be carefully assessed, in addition to the need to lower the high current unit wind power costs. Our previous study (Wang and Prinn 2010 Atmos. Chem. Phys. 10 2053) using a three-dimensional climate model suggested that a large deployment of wind turbines over land to meet about 10% of predicted world energy needs in 2100 could lead to a significant temperature increase in the lower atmosphere over the installed regions. A global-scale perturbation to the general circulation patterns as well as to the cloud and precipitation distribution was also predicted. In the later study reported here, we conducted a set of six additional model simulations using an improved climate model to further address the potential environmental and intermittency issues of large-scale deployment of offshore wind turbines for differing installation areas and spatial densities. In contrast to the previous land installation results, the offshore wind turbine installations are found to cause a surface cooling over the installed offshore regions. This cooling is due principally to the enhanced latent heat flux from the sea surface to lower atmosphere, driven by an increase in turbulent mixing caused by the wind turbines which was not entirely offset by the concurrent reduction of mean wind kinetic energy. We found that the perturbation of the large-scale deployment of offshore wind turbines to the global climate is relatively small compared to the case of land-based installations. However, the intermittency caused by the significant seasonal wind variations over several major offshore sites is substantial, and demands further options to ensure the reliability of large-scale offshore wind power. The method that we used to simulate the offshore wind turbine effect on the lower atmosphere involved simply increasing the ocean surface drag coefficient. While this method is consistent with several detailed fine-scale simulations of wind turbines, it still needs further study to ensure its validity. New field observations of actual wind turbine arrays are definitely required to provide ultimate validation of the model predictions presented here.

Offshore outsourcing and political risk: India in 2004  

Science Journals Connector (OSTI)

The results of the 2004 Indian elections were surprising as the victory of the Congress party was unforeseen by most pre-poll and exit surveys. The unexpected political change, with an associated shift from a centre-right to a centre-left government presented an unanticipated discontinuity in the business environment. We examine whether US companies that had offshored to India faced heightened levels of political risk when election results were announced. A unique contribution of the paper is that we also examine whether US companies that offshored to India in early-2004, faced greater political risk than companies that offshored to the country in 2002 and 2003. Results indicate an increase in political risk as manifested as an increase in systematic risk. Companies that offshored in 2004 faced greater political risk as compared to companies that offshored earlier. Our findings validate the use of a political risk premium when evaluating offshore ITES projects.

Precision micro drilling with copper vapor lasers  

SciTech Connect

The authors have developed a copper vapor laser based micro machining system using advanced beam quality control and precision wavefront tilting technologies. Micro drilling has been demonstrated through percussion drilling and trepanning using this system. With a 30 W copper vapor laser running at multi-kHz pulse repetition frequency, straight parallel holes with size varying from 500 microns to less than 25 microns and with aspect ratio up to 1:40 have been consistently drilled on a variety of metals with good quality. For precision trepanned holes, the hole-to-hole size variation is typically within 1% of its diameter. Hole entrance and exit are both well defined with dimension error less than a few microns. Materialography of sectioned holes shows little (sub-micron scale) recast layer and heat affected zone with surface roughness within 1--2 microns.

Drop pressure optimization in oil well drilling  

Science Journals Connector (OSTI)

In this research work we are interested in minimizing losses existing when drilling an oil well. This would essentially improve the load losses by acting on the rheological parameters of the hydraulic and drilling mud. For this rheological tests were performed using a six-speed rotary viscometer (FANN 35). We used several rheological models to accurately describe the actual rheological behavior of drilling mud oil-based according to the Pearson's coefficient and to the standard deviation. To model the problem we established a system of equations that describe the essential to highlight purpose and various constraints that allow for achieving this goal. To solve the problem we developed a computer program that solves the obtained equations in Visual Basic language system. Hydraulic and rheological calculation was made for in situ application. This allowed us to estimate the distribution of losses in the well.

Data transmission element for downhole drilling components  

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.

Operational Impacts of Large Deployments of Offshore Wind (Poster)  

SciTech Connect

The potential operational impact of deploying 54 GW of offshore wind in the United States was examined. The capacity was not evenly distributed; instead, it was concentrated in regions with better wind quality and close to load centers (Table 1). A statistical analysis of offshore wind power time series was used to assess the effect on the power system. The behavior of offshore wind resembled that of onshore wind, despite the former presenting higher capacity factors, more consistent power output across seasons, and higher variability levels. Thus, methods developed to manage onshore wind variability can be extended and applied to offshore wind.
