摘要

The objective of this project is to demonstrate systems for economically extracting, collecting, and utilizing methane recovered from coalbeds. The results of this effort are intended to provide the economical and technical information necessary for implementation of expanded methane recovery operations by industry. This report covers the second phase of the project. The site on which the project is being conducted is an 850 acre tract of land owned by the Westinghouse Electric Corporation in Westmoreland County, Pennsylvania and known as the Waltz Mill Site. The objective of Phase II was to further explore the site to improve its definition as a methane fuel reservoir and to develop the design of a system capable of providing a large-scale demonstration of the recovery of coalbed methane and utilization of this resource in an industrial application, i.e., process heat and electric power. To meet the second phase objective, it was necessary to obtain cores for analysis from additional well sites, perform selective drill stem tests, define additional well locations based on test and analytical results, and incorporate these well locations into the system design for gas utilization. Three new wells were cored and drill stem testing was conducted on two of them. The Waltz Mill site has been evaluated as containing 7960 mcf of coalbed methane per acre. The producing well developed in the first phase of the project continued in operation except for brief periods of shutdown for equipment maintenance. The well has attained a peak flow rate of 85.3 mcf/day and an average daily flow rate in excess of 38 mcf. (ERA citation 05:021698)
