Potential for gas migration due to coalbed methane development

Description

Coalbed gas (CBG) effectively consists of methane with minor amounts of ethane and propane, but no hydrogen sulphide (H2S). Recognition of CBG as an increasingly important energy resource has led to rapid expansion of exploration activity. Rapid development started in the 1980s in the western United States of America (USA), and has spread over the last six years to the Western Canadian Sedimentary Basin (WCSB). Increased production activities have brought increased awareness of environmental issues surrounding CBG development. In particular, reports of negative experiences associated with early CBG development in the USA have raised stakeholder concerns in Canada. Alberta CBG development has largely avoided the water resources issues experienced in the USA from CBG exploitation for two reasons. The major CBG resource plays in Canada to date have been in ‘dry’ coals, while ‘wet’ CBG coals developed in the USA required dewatering in order to recover the gas. Secondly, the rapid increase in Alberta CBG development occurred after Alberta regulators had already implemented protective legislation to address environmental concerns associated with protection of groundwater resources. Further regulations have been added, requiring a baseline water well testing program (May 2006), monitoring of groundwater production above the base of groundwater protection (October 2006), and prescriptive approaches to drilling and installing CBG production wells.
