The goal of dewatering is to decrease the pressure in the coal seam by pump-ing water from the well. The decrease in pressure allows methane to desorb from the coal and flow as a gas to the surface of the well. After desorption, methane gas diffuses to microspores and then follows a Darcy flow pattern from fractures to wellbore.
