CA 2560354

A coal bed methane degassing tool is installed at the bottom of a first joint of production casing. As the casing is lowered into the well hole, the tool is fished to the top of the casing as more joints are added. The pressure at the tool may be recorded and logged. Any excessive pressure observed at the tool may be bled off by the tool automatically or manually, As more casing is tripped in, the tool is brought to the top. At the end of the run a log of formation pressure is established. Reservoir engineers can determine reserves in coal bed methane wells drilled axial completed before the well is bled off and the tool is removed.
