Numerical simulation study on the bottom-water invasion in the carbonate gas reservoir with high angle fractures and high permeability zones

Numerical simulation of carbonate gas reservoir with bottom-water is still a challenging issue, due to the presence of nature conductive fractures. When the water invades into the gas well, the permeability of gas phase decreases sharply. The high angle fractures and high permeability zones have a serious impact on the production performance of the gas wells. The characteristic of the water invasion was unpredictable in conventional dynamic analysis.
