Development of coalbed-methane reservoirs requires accurate determination of gas in place and natural fracture permeability. This paper outlines steps needed to evaluate reservoir properties and to predict well deliverability. Procedures are documented with data and analyses from San Juan basin development projects. The paper includes an example of the accuracy of gas-content determinations from pressure-, sidewall-, and conventional-core and drill-cuttings samples; presents specifications for complete log suites and analysis techniques for gas-content estimates; discusses drillstem-test (DST) procedures; and outlines prediction of well deliverability.
