Abstract In-seam horizontal boreholes are used to collect coalbed methane (CBM). Physical simulations of CBM drainage by in-seam horizontal boreholes are conducted. The evolution of gas pressure and permeability ratio indicate a rapid decline in a short time. As time goes by, the permeability ratio recovers, and the gas pressure declines slowly.

The stress state of coal surrounding a coalbed methane (CBM) production well is affected by the bottom hole flowing pressure (BHFP). The permeability of coal shows a marked change under compression. The BHFP must be restricted to a specific range to favor higher permeability in the surrounding coal and thus higher productivity of the well. A new method

Gas production from coal seams is extremely important for safety of coal mining by controlling methane emissions and also for utilizing the gas as an unconventional energy resource. In this work, an integrated study of coalbed methane (CBM) production history matching and filter-based multiple point geostatistical simulation is presented to quantify ...
