Rock Creek methane from Multiple-Coal-Seams Completion Project. Annual report, January-December 1990. 1. 1. 4 Coalbed-Methane Multiple-Coal-Seam project 305
The Multiple Coal Seams Completion Project is a joint venture developing drilling, completion, testing, stimulation, and production procedures for economic production of methane from multiple coal seams. During the report period, extensive well testing was conducted. Slug tests and injection tests were performed on Wells P6 and P7 in addition to slug tests on several offsite wells. Wells P6 and P7 were stimulated in the Black Creek Group with cross-linked gel treatments. Production peaked at 175 MCFD and 46 MCFD for Wells P6 and P7, respectively. Pressure has been reduced so much in the project area that production was declining for all of the wells through the later half of 1990. Corehole C4 was completed in June 1990. Desorption tests from cores show that, in an area 500 to 600 feet from production wells, up to 80% of the original methane resource has been recovered. Additional Wells P3A (Pratt), M6 (Mary Lee and Black Creek monitor well), and P8 (originally M8) were drilled and cased. Permeability and compressibility testing will be conducted on these wells in 1991 and Well P3A will be stimulated in the Pratt Coal Group with unconventional treatments. Water, gas analyses, rate, and pressure data for 10 wells and reservoir for 18 monitor wells was recorded and distributed to various project support contractors for analysis.
