| Summary: | Coalbed Methane is one of the developing alternative energy source, in which. Indonesia's CBM potential is large enough to occupy the 6th position in the world. The main component in CBM is methane (CH4). Methane is generally considered as a cleaner form of energy when compared to coal and oil. The cost of CBM exploration is relatively lower and the wells used to produce CBM have more effective drilling costs. Therefore, the utilization of CBM in Indonesia must be done immediately to meet the energy needs in the country. Drilling technology or advanced stimulation is required to produced CBM at commercial flow rates. One effort that can be done to improve the productivity of CBM is to conduct hydraulic fracturing to the reservoir. Hydraulic fracture stimulation can increase the productivity of the wells. In this study, a sensitivity test will be conducted on two parameters, the fracture width and the half wing fracture length (fracture geometry). This study shows that in the Anthracite and Sub Bituminous reservoirs the best sensitivity result is to enlarge the length of single wing fracture length and reduce the fracture width. While for the High Volatile Bituminous reservoir is the opposite. The optimum length of one wing fracture for Anthracite, High Volatile Bituminous, and Sub Bituminous reservoirs are 194.80 ft, 91.91 ft and 221.80 ft, respectively. While the optimum fracture widths for Anthracite, High Volatile Bituminous, and Sub Bituminous reservoirs are respectively 0.00134 ft, 0.01032 ft, and 0.00468 ft. The optimum Fold of Increase (FOI) for each Anthracite, High Volatile Bituminous, and Sub Bituminous reservoir are respectively 4.74, 3.19, and 5.15. |
