Well Testing in Coalbed Methane (CBM) Wells: An

Abstract. In 1993, methane seepage was observed near coalbed methane wells in southwestern Colorado. Well tests were conducted to identify the source of the seeps. The well tests were complicated by two-phase flow, groundwater flow, and gas readsorption. Using the test results, production from the area was simulated. The cause …

CBM reservoir evaluation

Well testing. Buildup tests, injection/falloff tests, and slug tests each have been used successfully to determine critical reservoir and completion parameters in CBM reservoirs. In a buildup test, a well that is producing at a constant rate is shut in, and the downhole pressure is measured as it builds up. In an injection/falloff test, a well ...
