Rock Creek methane from Multiple Coal Seams Completion Project. Annual report, January 1989-December 1989
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, much 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. Hydrological testing of Well P4 indicates there is communication between the Black Creek and Mary Lee Coal Groups. A drawdown study of the field and a mass balance analysis indicate about 10 percent of the gas within the area of drawdown has been produced. Production summaries of gas and water production is stable or declining for all of the wells. Production is good from Well P5 that was completed in the rock above the bottom seams in both the Mary Lee and Black Creek Groups. The sand packed rock interval has screened out coal fines and proppant which are normally produced during dewatering. This has allowed Well P5 to be pumped for 530 consecutive days with no pump problems. Treatment of water produced from the wells has been modified to adjust for the increasing proportion of water from the Black Creek Group with a higher TDS and iron levels.
