Abstract

Gas is produced from a tight coal formation. A well bore pattern providing coverage of an area of a coal seam having an effective permeability below seven millidarcies is used to remove water from the area of the coal seam. A sufficient volume of water is removed from the area of the coal seam to obtain at substantially continuous flow conditions and within two years of a start of water production a gas production peak rate. The gas production peak rate has a decline that reaches one-third of the peak rate after at least twenty-five percent of gas in the area has been produced.
