COAL-SEQ PROJECT UPDATE: FIELD STUDIES OF ECBM RECOVERY/CO2 SEQUESTRATION IN COALSEAMS

摘要

In October 2000, a three-year government-industry project known as the Coal-rnSeq project was launched in the United States. The project is studying the feasibility ofrnCO2 sequestration in deep, unmineable coalseams using enhanced coalbed recoveryrntechnology. The Coal-Seq project is specifically focused on understanding the results ofrnactual field experiments via reservoir modeling, with laboratory studies filling arnsupporting, not primary, role. The fields being studied are both in the San Juan basin.rnThe sites are the Allison Unit, operated by Burlington Resources and the Tiffany Unit,rnoperated by BP America. These two sites are the only two in existence today, worldwide,rnwhere long-term, multi-well injection of CO2 or N2 is being performed. In addition to thernfield studies, supporting analytic work in the areas of multi-component sorption behavior,rnand coal swelling with CO2 adsorption, are being performed.
