ADVANCED TECHNOLOGIES FOR STRIPPER GAS WELL ENHANCEMENT

Description: As part of Task 1 in Advanced Technologies for Stripper Gas Well Enhancement, Schlumberger--Holditch Reservoir Technologies (H-RT) has joined with two Appalachian Basin producers, Great Lakes Energy Partners, LLC, and Belden & Blake Corporation to develop methodologies for identification and enhancement of stripper wells with economic upside potential. These industry partners have provided us with data for more than 700 wells in northwestern Pennsylvania. Phase 1 goals of this project are to develop and validate methodologies that can quickly and cost-effectively identify wells with enhancement potential. We have continued to enhance and streamline our software, and we are testing the final stages of our new Microsoft{trademark} Access/Excel based software. We are continuing to process this well data and are identifying potential candidate wells that can be used in Phase 2 to validate the new methodologies. In addition, preparation of the final technical report is underway.

ADVANCED TECHNOLOGIES FOR STRIPPER GAS WELL ENHANCEMENT

Description: As part of Task 1 in Advanced Technologies for Stripper Gas Well Enhancement, Schlumberger Data & Consulting Services (DCS) joined with two Appalachian Basin producers, Great Lakes Energy Partners, LLC, and Belden & Blake Corporation to develop methodologies for identification and enhancement of stripper wells with economic upside potential. These industry partners previously provided us with data for more than 700 wells in northwestern Pennsylvania. Phase 1 goals of this project are to develop and validate methodologies that can quickly and cost-effectively identify underperforming wells with remediation potential. We have enhanced and streamlined our software and are using it with the latest versions of Microsoft's{trademark} Access and Excel programs. During the last quarter of 2002, Great Lakes provided us with additional data for approximately 2,200 wells located in their Cooperstown field situated in northwestern Pennsylvania. We identified approximately 130 potential remediation candidates, and Great Lakes personnel are currently reviewing this list for viable remediation. Within the last few weeks, a list of five candidates have been chosen for refract, in addition to two alternate wells. This field has provided a rigorous test of our software and analytical methods. We have processed all the information provided to us including the Cooperstown data. Great Lakes also provided supplemental data listing the original operator of the wells. We have determined whether a statistically significant number of underperformers correlate to specific operators and/or their associated completion/stimulation methods. In addition, the DOE has reviewed a draft version of a final report.

Microseismic monitoring of the B-sand hydraulic fracture experiment at the DOE/GRI multi-site project

Description: Six hydraulic-fracture injections into a fluvial sandstone at a depth of 4500 ft were monitored with multi-level triaxial seismic receivers in two wells, resulting in maps of the growth and final geometry of each fracture based upon microseismic activity. These diagnostic images show that the hydraulic fractures are highly contained for smaller-volume KCl-water injections, but height growth is significant for the larger-volume, higher-rate, higher-viscosity treatments. Fracture lengths for most injections are similar. Final results are also compared with fracture models.

Steerable percussion air drilling system

Description: In the Steerable Percussion Air Drilling System (SPADS), air percussion is used to drill directionally in hard formations. Compared to mud or air powered PDM motors, SPADS offers directional drilling at high penetration rate, reduced mud costs, negligible formation damage, and immediate indication of hole productivity. Field tests turned up problems ranging from tool design to operation procedures; remedies were developed. There is an optimum WOB (weight on bit) at which torque is reasonably low. The hammer was tested at three different line pressures (200, 300, 350 psig) at optimum WOB in granite, limestone, and sandstone.

Compendium of regulatory requirements governing underground injection of drilling waste.

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

LOW COST METHODOLOGIES TO ANALYZE AND CORRECT ABNORMAL PRODUCTION DECLINE IN STRIPPER GAS WELLS

Description: A study group of 376 Clinton Sand wells in Ohio provided data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the causes of the abnormal production decline. Analysis of the historic frequency of the problem indicates over 70% of the wells experienced abnormal production decline. The most frequently occurring causes of abnormal production declines were determined to be fluid accumulation (46%), gas gathering restrictions (24%), and mechanical failures (23%). Data collection forms and decision trees were developed to cost-effectively diagnose the abnormal production declines and suggest corrective action. The decision trees and data collection sheets were incorporated into a procedure guide to provide stripper gas well operators with a methodology to analyze and correct abnormal production declines. The systematic methodologies and techniques developed should increase the efficiency of problem well assessment and implementation of solutions for stripper gas wells. This eight quarterly technical progress report provides a summary of the deliverables completed to date, including the results of the remediations, the procedure guide, and the technology transfer. Due to the successful results of the study to date and the efficiency of the methodology development, two to three additional wells will be selected for remediation for inclusion into the study. The results of the additional remediations will be included in the final report.

Evaluation of slurry injection technology for management of drilling wastes.

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

Low cost methodologies to analyze and correct abnormal production decline in stripper gas wells

Description: The goal of this research program is to develop and deliver a procedure guide of low cost methodologies to analyze and correct problems with stripper wells experiencing abnormal production declines. A study group of wells will provide data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the historic frequency of the causes of the production problems. Once the most frequently occurring causes of the production problems are determined, data collection forms and decision trees will be designed to cost-effectively diagnose these problems and suggest corrective action. Finally, economic techniques to solve the most frequently occurring problems will be researched and implemented. These systematic methodologies and techniques will increase the efficiency of problem assessment and implementation of solutions for stripper gas wells. This third quarterly technical report was to describe the data reduction and methodologies to develop decision trees, identify cost effective techniques to solve the most frequently experienced problems and then apply the methodology to a group of wells where recent problems have developed. Further, this third quarterly technical report was to describe the data reduction and methodologies to select the two wells with the greatest potential for increase and also having the most frequently occurring problem, and evaluate the results of the methodology and the implemented procedure. However, preparation and analysis of the decision trees is more complex than initially anticipated due to the combination of problems rather than identifiable individual problems. Therefore, this portion of the study is still in progress. We have requested and been granted verbal approval for a six month no cost extension to allow more time to thoroughly investigate this portion of the study. The delivery of the decision trees will be included in future technical reports. Work on the other tasks to be completed ...

According to the original proposal, this fourth quarterly technical report was to deliver a procedure guide, a summary report, and a Society of Petroleum Engineers technical paper. However, James Engineering, Inc. was granted a six month, no cost extension to allow the required time to thoroughly investigate and prepare these portions of the study, therefore completion of the current deliverables has been re-scheduled. James Engineering, Inc. did present preliminary results of the study during a panel discussion on Stripper Gas Wells at the Society of Petroleum Engineers' Eastern Regional Meeting held in Morgantown, West Virginia October 19, 2000. No cost to the study was incurred for the preliminary presentation.

Permeability reduction by pyrobitumen, mineralization, and stress along large natural fractures in sandstones at 18,300 ft. depth: Destruction of a reservoir

Description: Production of gas from the Frontier Formation at 18,300 R depth in the Frewen No. 4 Deep well, eastern Green River basin (Wyoming), was uneconomic despite the presence of numerous open natural fractures. Initial production tested at 500 MCFD, but dropped from 360 MCFD to 140 MCFD during a 10-day production test, and the well was abandoned. Examination of the fractures in the core suggests several probable reasons for this poor production. One factor is the presence of a hydrocarbon residue (carbon) which filled much of the porosity left in the smaller fractures after mineralization. An equally important factor is probably the reorientation of the in situ horizontal compressive stress to a trend normal to the main fractures, and which now acts to close fracture apertures rapidly during reservoir drawdown. This data set has unpleasant implications for the search for similar, deep fractured reservoirs.

Natural gas productive capacity for the lower 48 states 1984 through 1996, February 1996

Description: This is the fourth wellhead productive capacity report. The three previous ones were published in 1991, 1993, and 1994. This report should be of particular interest to those in Congress, Federal and State agencies, industry, and the academic community, who are concerned with the future availability of natural gas. The EIA Dallas Field Office has prepared five earlier reports regarding natural gas productive capacity. These reports, Gas Deliverability and Flow Capacity of Surveillance Fields, reported deliverability and capacity data for selected gas fields in major gas producing areas. The data in the reports were based on gas-well back-pressure tests and estimates of gas-in-place for each field or reservoir. These reports use proven well testing theory, most of which has been employed by industry since 1936 when the Bureau of Mines first published Monograph 7. Demand for natural gas in the United States is met by a combination of natural gas production, underground gas storage, imported gas, and supplemental gaseous fuels. Natural gas production requirements in the lower 48 States have been increasing during the last few years while drilling has remained at low levels. This has raised some concern about the adequacy of future gas supplies, especially in periods of peak heating or cooling demand. The purpose of this report is to address these concerns by presenting a 3-year projection of the total productive capacity of natural gas at the wellhead for the lower 48 States. Alaska is excluded because Alaskan gas does not enter the lower-48 States pipeline system. The Energy Information Administration (EIA) generates this 3-year projection based on historical gas-well drilling and production data from State, Federal, and private sources. In addition to conventional gas-well gas, coalbed gas and oil-well gas are also included.

Horizontal oil well applications and oil recovery assessment. Volume 2: Applications overview, Final report

Description: Horizontal technology has been applied in over 110 formations in the USA. Volume 1 of this study addresses the overall success of horizontal technology, especially in less-publicized formations, i.e., other than the Austin Chalk, Bakken, and Niobrara. Operators in the USA and Canada were surveyed on a formation-by-formation basis by means of a questionnaire. Response data were received describing horizontal well projects in 58 formations in the USA and 88 in Canada. Operators` responses were analyzed for trends in technical and economic success based on lithology (clastics and carbonates) and resource type (light oil, heavy oil, and gas). The potential impact of horizontal technology on reserves was also estimated. A forecast of horizontal drilling activity over the next decade was developed.
