Summary:
The mechanisms responsible for the high fracturing pressures observed in coal are examined in order to specify stimulation procedures required to achieve fracture characteristics that optimize gas production. The work focuses on investigating whether cavity completions are more successful as a stimulation technique in certain formations. The report provides the details of laboratory test results and analyses leading to the delineation of the "high" treating pressure mechanisms in coal and the procedural considerations for completion and hydraulic fracturing stimulation in order to avoid these "high" treating pressures. The section on cavity completions addresses the field data evaluation and laboratory work performed for determination of the mechanisms leading to elevated post-cavity production rates. Analysis of the mechanical responses of coal summarizes relevant aspects of poroelasticity and plasticity, pertinent to both hydraulic fracturing and cavity completions. Details of testing procedures and additional published papers on the subject are included in the appendixes.
