Coal Bed Methane, Enhance Production, Wettability Alteration.


It is of great importance and significance to study the production improvement technology for coal bed methane. Wettability alteration technology has been successfully applied to enhance oil production and recovery. However, literature on wettability technology used to enhance production of coal bed methane has not been reported. In this paper, a physical model was developed to describe the mechanism of wettability alteration technology to enhance coal bed methane. Gas-water displacement test was conducted in coal samples with and without the wettability alteration to gas wetness. Comparison of gas-water relative permeability curve before and after wettability alteration showed that wettability alteration technology could increase gas phase relative permeability, and reduce water residual water saturation in the gas-water displacement. The experimental results demonstrated that the wettability alteration to gas wetness technology can enhance the production of coal bed methane.
