Description
While the potential economic and environmental benefits of CMM generated electricity are recognizable, an uncertain energy market and declining coal production impedes project development. Moreover, legal regulatory, and technical challenges make CMM project business risks and commercial feasibility difficult to assess, particularly at active mines where production can be highly variable.

Description
Questa Engineering Corporation has prepared a basin-wide coalbed methane reservoir model of the Colorado portion of the San Juan Basin. The model simulates the effects of production from all existing and proposed Fruitland coal wells in Colorado. The effects of dewatering, gas adsorption and desorption, and historical production are included in the model. It also provides a technology to evaluate coalbed methane infill drilling and gas seepage at...

Description
A basin-wide coalbed methane reservoir model of the Colorado portion of the San Juan Basin. This model, which is referred to as the 3M CBM MODEL, simulates the effects of production from all existing and proposed Fruitland coal wells in Colorado. The effects of dewatering, gas adsorption and desorption, and historical production are included in the model. The 3M CBM MODEL provides a tool to evaluate the effects of coalbed methane infill drilling and...
13) Greenhouse gas neutrality assessment of coal mine methane and waste-to-energy pyrolysis projects

Description
Colorado's Renewable Energy Standard (RES) has been in effect since 2004, but in 2013, coal mine methane (CMM) and synthetic gas produced by pyrolysis of municipal solid waste (MSW) were added as eligible energy resources as long as the renewable energy projects are greenhouse (GHG) neutral. The purpose of this study was to develop a framework for project developers and the Colorado Public Utilities Commission (PUC) to assess the GHG-neutrality of...

Description
"The purpose of this study was to develop a quantitative assessment of the levels of stream depletion or reduction in formation outflows (Spring flows or flowing stream systems gaining from contact with formations) that may be occurring as a result of the removal of water by coalbeds methane wells. .... The concern has been raised that the removal of ground water from aquifers that may be tributary to the surface stream system could be resulting in...
