... generated from producing coalbed methane (CBM) also varies from produced water from both oil and gas production activities. In coalbed methane drilling, oil and grease are less of a concern constituent in the produced water when compared with others. Inclusions of coalbed methane water that need...

... Abstract A hydro-geomechanical coalbed methane reservoir characterization workflow is reviewed and applied to three field cases from the same coalseam formation. The workflow begins from core sample characterization and ends at reservoir performance. A core sample and geophysical logging rock...

... Abstract Coalbed Methane (CBM) is becoming a significant portion of the US gas resource and is gaining importance in Australia, China, Indonesia and Europe. CBM reserves in the United States are estimated at some 450 Tscf. In Australia, CBM resources exceed 300 Tscf, while China has a resource...

This allows for greater understanding of the effects of the reservoir upon the economics of the project, as well as providing a means to economically optimize stimulation design. coalbed methane gas production npv...

..." of the coal, which consequently altered the coal cleat structure ( Gash, 1991 ). Abstract Relative permeability of coal to gas and water is an important variable in coalbed methane (CBM) reservoir development as it is required for reserve estimation and field production planning. In this study, two coal...

Then, we used this relationship to extrapolate original unconventional gas in place...

... Abstract Coalbed methane (CBM) production in the San Juan Basin of northwestern New Mexico and southwestern Colorado has spanned over 30 years. Some parts of the field, such as the high-permeability Fairway, are now in a mature stage of reservoir pressure depletion. Optimization of well...

... Abstract Fort Assiniboine is a commercial Coalbed Methane field in central Alberta, Canada with over 200 multilateral horizontal wells in the Upper Cretaceous Mannville coal. The Mannville coal seams in this area are under-saturated. Therefore the reservoir's ability to dewater the coal through...
