Dewatering rate optimization for coal-bed methane well

Low dewatering rate will make the gas flow slower so that longer, even uneconomical extraction times are required. While high dewatering rate will bring more problems such as coal break and fine coal generation, stress sensitivity or two-phase flow in the earliest stage, all of them will reduce the productivity. First, it will make the water
