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...
