수압파쇄된 CBM 저류층에서 수평정의 생산 거동예측을 위한 생산자료 분석

다국어 초록 (Multilingual Abstract)

Production data from hydraulically fractured well in coalbed methane (CBM) reservoirs was analyzed using decline curve analysis (DCA), flow regime analysis, and flowing material balance to forecast the production performance and to determine estimated ultimate recovery (EUR) and timing for applying the DCA. To generate synthetic production data, reservoir models were built based on the CBM propertie of the Appalachian Basin, USA. Production data analysis shows that the transient flow (TF) occurs for 6~16 years and then the boundary dominated flow (BDF) was reached. In the TF period, it is impossible to forecast the production performance due to the significant errors between predicted data and synthetic data. The prediction can be conducted using the production data of more than a year after reached BDF with EUR error of approximately 5%.
