Worldwide selection of early opportunities for CO2-enhanced oil recovery and CO2-enhanced coal bed methane production

A study has been undertaken to assess the potential for low cost opportunities for CO2 capture and storage/sequestration worldwide. Such opportunities should provide options for early implementation of projects worldwide. They combine high purity (100%) CO2 gas streams with short transmission distance and potentially profitable CO2 enhanced fossil fuel recovery schemes such as CO2-EOR and CO2-ECBM, which simultaneously sequester CO2. The study has used a geographical information system to link high purity CO2 point sources to oil and gas reservoirs within 100 km of the point source. In doing this some 420 possible CO2-EOR opportunities and a further 79 possible CO2-ECBM opportunities were identified.
