Design and Operational Considerations of a Pilot Project for Sequestration of Carbon Dioxide and Enhanced Coalbed Methane Production in an Eastern Coal Seam

摘要

Because of increased concern about anthropogenic carbon dioxide emissions,the geological sequestration of carbon dioxide is being examined as one means of reducing these emissions. Unmineable coal seams are considered good candidates for such sequestration projects,because they have served as excellent storage reservoirs for sorbed gases for geological time periods. Additionally,the enhanced methane production from these reservoirs makes a favorable contribution to the economics of the projects.
