THE PLAINS CO2 REDUCTION (PCOR) PARTNERSHIP: DEVELOPING CARBON MANAGEMENT OPTIONS FOR THE CENTRAL INTERIOR OF NORTH AMERICA
The PCOR Partnership has completed four field validation tests thus far: 1) Apache Canada Limited hosted a combined enhanced oil recovery (EOR)/sequestration activity that injected acid gas (approximately 70% CO2 and 30% H2S) into a pinnacle reef structure from its Zama, Alberta, gas plant for use as a miscible flood agent; 2) a huff ‘n’ puff EOR project in the Williston Basin demonstrated the potential of using CO2 in a tertiary oil recovery operation in a carbonate formation at depths of approximately 8000 feet; 3) the CO2 sequestration and enhanced coalbed methane potential in a Williston Basin lignite was investigated; and 4) a terrestrial field validation test developed carbon offsets from the use of alternative land management of wetlands in the Prairie Pothole Region.
The PCOR Partnership is now teaming with industrial partners to conduct two commercial-scale (greater than 1 million tons per year) CCS demonstrations in the region. One of the large-scale tests will demonstrate CO2 storage in a saline formation, while the other will be a combined CCS and EOR demonstration. The sources of CO2 in both demonstrations are natural gas-processing facilities. The commercial-scale demonstration tests are designed to establish the technical and economic efficacy of CCS in the region, and injections are planned to begin in 2012 for both projects.
