THE PLAINS CO2 REDUCTION (PCOR) PARTNERSHIP: PHASE II AND III ACTIVITIES
vast energy, agricultural, forest, and water resources and offers significant opportunities for both geologic and terrestrial sequestration.
Three geologic field validation tests and one terrestrial test are now under way in Phase II(20052009). Apache Canada Limited is hosting a combined enhanced oil recovery (EOR)/sequestration activity that is injecting acid gas (approximately 70% CO2 and 30% H2S) from the Zama, Alberta, gas plant for use as a miscible flood agent. An EOR project in the Williston Basin is being designed to demonstrate the potential of using CO2 in a tertiary oil recovery operation at depths of over 10,000 feet. The potential for CO2 sequestration and enhanced coalbed methane in Williston Basin (Burke County, North Dakota) lignite is also being investigated in a five-spot test that was drilled in the spring of 2007. The terrestrial field validation test (McPherson County, South Dakota) is under way to develop carbon offsets from alternate management of wetlands in the Prairie Pothole Region in partnership with Ducks Unlimited Incorporated.
The 10-year Phase III Program of the PCOR Partnership, initiated in the fall of 2007, features two commercial-scale demonstrations of geologic sequestration of CO2 from human activities. These two demonstrations, the Western Canada Basin Demonstration in northeastern British Columbia in western Canada and the Williston Basin Demonstration in western North Dakota in the west-central United States, are designed to sequester a total of over 20 million tons of CO2 by 2017 in deep, well-characterized, underground storage reservoirs.
