Adsorption/desorption isotherms were established for powdered coal samples. Gas pressure-permeability relationships for cylindrical specimens of coal, under triaxial stress conditions, were also determined. Gas pressure-volumetric strain relationship

Abstract A model to correct for the size and time (frequency) scale variations of measured mechanical properties is presented. We show by comparing field data and laboratory data that large effects can occur. It follows that large errors can result f

SPE Members Abstract The traditional concept of coalbed methane production is one where the coal natural fracture system is initially 100% saturated with water and that this water must be produced to initiate gas production. This paper summarizes an

SPE Members Abstract Between 1983 and 1993, the coalbed methane (CBM) industry changed from a high cost operation to a competitive main line gas resource. In 1983, there were approximately 165 coalbed methane wells in the United States with an estima

SPE Members Abstract The use of foamed fluids has become popular in coal and shale reservoirs due to their inherent non-damaging properties. Foam is generally considered to be a perfect transport fluid. However, the proppant transport properties have
