| Summary: | Hydraulic fracturing is a simulation method performed by pumping pressurized fluid to reach the fracture pressure of the formation to make fracture as a better flow path of the formation fluids. In general, this method is applied to reservoir with very low permeability and abundant reserves which has uneconomical gas production rate as if produced conventionally. Thus this method is suitable to ce apllied in Coalbed Methane (CBM) reservoir. In CBM reservoir, hydraulic fracturing method is used to improve conductivity of the formation around the well in order to accelerate dewatering process and increase gas production rate. The use of this method in CBM reservoir is not a something new, this method has been used widely in United State for producing methane gas from major coal basin in this country as in San Juan Basin and Warior Basin.
Fracturing fluids is a very influential component in the succes of the hydraulic fracturing process. Fluid plays the role in making a fracture and transporting proppant so that the fracture is not re-close. This study will review how the effect of the fluid selection and the fluid pumping rate to obtain optimal design of hydraulic fracturing treatment. This study is conducted to simulate the effect of the type and fluid pumping rate to conductivity and efficiency. There are three main components that will be simulated: fluid efficiency, ability of the fluid to transport proppant and effect of pumping rate to fluid efficiency. Data needed in simulation are taken from San Juan Basin’s data and literature. The results will be obtained from this simulation is the type of fluid that has optimat performance to make fracture in CBM reservoir. The study is expected to be usefull for further research. |
