Zama Acid Gas EOR, CO2 Sequestration, and Monitoring Project

Nominators: Canada (lead) and United States

Zama Acid Gas EOR, Sequestration and Monitoring Project

This is a pilot-scale project, located in northern Albera, Canada, that involves utilization of acid gas (approximately 70% CO2 and 30% hydrogen sulfide) derived from natural gas extraction for enhanced oil recovery. Project objectives are to predict, monitor, and evaluate the fate of the injected acid gas; to determine the effect of hydrogen sulfide on CO2 sequestration; and to develop a "best practices manual" for measurement, monitoring, and verification of storage (MMV) of the acid gas. Acid gas injection was initiated in December 2006 and will result in sequestration of about 25,000 tons (or 375 million cubic feet) of CO2 per year.

Recognized by the CSLF at its Paris meeting, March 2007
