Abstract

Many parameters affect the efficiency of enhanced recovery operations in methane-containing coal beds. Some of the most important parameters in this research were studied. The best output for performing enhanced recovery of these parameters was obtained in ECLIPSE reservoir simulation software. After selecting the data for sensitivity analysis, the corresponding models were defined with different conditions. Then the results of this simulation were analyzed. Sensitivity analysis indicators include the amount of produced carbon dioxide, as well as the rate of this product plus the amount of carbon dioxide stored in the reservoir which is important for the oil and gas industry from the environmental point of view. According to the results of the sensitivity analysis in line with the studied parameters, it can be stated that if the permeation parameters and the porosity of the slit system be lower than a certain extent, they will lead to failure in the process of enhanced recovery. Meanwhile, the other three parameters, reservoir pressure, Langmuir pressure, and Yang coefficient, only affect the efficiency of the enhanced recovery operation.
