Vertical borehole design and completion practices used to remove methane gas from mineable coalbeds

Description: Coalbed gas drainage from the surface in advance of mining has long been the goal of researchers in mine safety. Bureau of Mines efforts to achieve this goal started about 1965 with the initiation of an applied research program designed to test drilling, completion, and production techniques for vertical boreholes. Under this program, over 100 boreholes were completed in 16 different coalbeds. The field methods derived from these tests, together with a basic understanding of the coalbed reservo… more

Drilling and early testing of a sidetrack from the slant hole completion test well

Description: During the winter of 1990 to 1991, the Department of Energy evaluated several options to completing the originally-planned slant hole production tests. A decision was made to sidetrack the original hole and to redrill the 60 and 90{degrees} sections. The objectives for drilling the sidetrack to the original slant hole wellbore are as follows: (1) Test high angle and horizontal drilling and completion technologies as an alternative to vertical wells and hydraulic fracture treatments in tight, na… more

Description: Detailed megascopic and microscopic petrographic analyses were conducted on samples of the Lower Kittanning seam from western Pennsylvania. Relationships were sought between the paleoenvironmental setting of the coal swamp and the vertical and lateral variability of lithotypes, maceral composition and vitrinite types. Megascopically, the four samples collected from the freshwater facies of the seam are similar in appearance and relative lithotype composition, and display no distinct vertical zo… more

Sampling and analyses report for December 1991 semiannual postburn sampling at the RM1 UCG site, Hanna, Wyoming

Description: The Rocky Mountain 1 (RM1) underground coal gasification (UCG) test was conducted from November 16, 1987, through February 26, 1988 at a site approximately one mile south of Hanna, Wyoming. The test consisted of a dual-module operation to evaluate the controlled retracting injection point (CRIP) technology, the elongated linked well (ELW) technology, and the interaction of closely spaced modules operating simultaneously. The test caused two cavities to form in the Hanna No. 1 coal seam and asso… more

Buried telemetry system for in-situ energy extraction

Description: During an in-situ energy extraction process, a continuous knowledge of the temperature profile through the combustion area is desirable for analysis and control. To provide this data, a telemetry system has been developed that will monitor the thermocouples from beneath the process bed, digitize the data into 12 bit words and store them into memory. Every six hours, the stored data is transmitted laterally through the earth to a receiver outside of the high temperature zone and then sent to the… more

Instrumentation and process control development for in situ coal gasification. Quarterly report, December 1979-March 1980

Description: The analysis of data for the Hanna IV and Hoe Creek in situ coal gasification tests raised questions concerning the fundamental controlling mechanisms of the process. The two main areas of concern are: (1) the air flow patterns; and (2) the initial cavity growth. Sandia National Laboratories is addressing these concerns by developing models of these processes. Results to date are in qualitative agreement with known phenomena. There have also been developments in data handling capability. These … more

Reserves in western basins

Description: This project requires generation of producible tight gas sand reserve estimates for three western basins. The requirement is to perform such reserve estimates using industry accepted practices so that results will have high credibility and acceptance by the oil and gas industry. The ultimate goal of the project is to encourage development of the tight gas formation by industry through reduction of the technical and economic risks of locating, drilling and completing commercial gas wells. The th… more

Improvements in Measuring Sorption-Induced Strain and Permeability in Coal

Description: Total worldwide CBM in-place reserves estimates are between 3500 Tcf and 9500 Tcf. Unminable coal beds have been recommended as good CO2 sequestration sites as the world prepares to sequester large amounts of greenhouse gases. In the U.S., these coal seams have the capacity to adsorb and sequester roughly 50 years of CO2 emissions from all the U.S. coal-fired power plants at today’s output rates. The amount and type of gas ad-sorbed in coal has a strong impact on the permeability of the coal se… more

Research and Development Concerning Coalbed Natural Gas

Description: The Powder River Basin in northeastern Wyoming is one of the most active areas of coalbed natural gas (CBNG) development in the western United States. This resource provides clean energy but raises environmental concerns. Primary among these is the disposal of water that is co-produced with the gas during depressurization of the coal seam. Beginning with a few producing wells in Wyoming's Powder River Basin (PRB) in 1987, CBNG well numbers in this area increased to over 13,600 in 2004, with pro… more

Refocused energy policy: a natural gas perspective

Description: The present administration's policy on energy development is briefly summarized. While the Department of Energy will be dismantled, several important functions will be preserved and will continue elsewhere in government. The administration's aim is not to present an energy blueprint to predetermine energy solutions, rather, policy is based on the belief that the marketplace must be allowed to determine the most economic and durable energy sources. Revision of the federal leasing policy is discu… more

Economic sensitivity study of UCG based on field performance, theory, and operational experience

Description: This paper provides the results of an economic analysis in which uncertainty has been minimized through the use of the following three types of information: (1) theoretical and experimental correlations of underground coal gasification (UCG) operating parameters; (2) detailed process design based on operational experience; and (3) sensitivity variables. Independent variables cannot be fixed with certainty - for example, gas heating values are known for short-term field tests but remain uncertai… more

Numerical Modeling of CO2 Sequestration in Geologic Formations - Recent Results and Open Challenges

Description: Rising atmospheric concentrations of CO2, and their role inglobal warming, have prompted efforts to reduce emissions of CO2 fromburning of fossil fuels. An attractive mitigation option underconsideration in many countries is the injection of CO2 from stationarysources, such as fossil-fueled power plants, into deep, stable geologicformations, where it would be stored and kept out of the atmosphere fortime periods of hundreds to thousands of years or more. Potentialgeologic storage reservoirs inc… more
