Overview of the Bell Creek Combined CO2 Storage and CO2 EOR Project
The PCOR Partnership is working with Denbury Onshore LLC (Denbury) to determine the effect of large-scale injection of CO2 into a deep clastic reservoir for the purpose of simultaneous CO2 enhance oil recovery (EOR) and CO2 storage at the Bell Creek oil field, which is owned and operated by Denbury. The CO2 will be obtained from the ConocoPhillips-owned Lost Cabin gas-processing plant in Fremont County, Wyoming, which currently generates approximately 50 million cubic feet of CO2 a day. The CO2 will be transported 232 miles to the site via pipeline and injected into an oil-bearing sandstone reservoir in the Lower Cretaceous Muddy Formation (also known as the Newcastle Formation) at a depth of approximately 4500 feet (1372 meters). The Muddy Formation within the boundaries of the Bell Creek oil field is characterized by high permeability (4251175 mD) and high porosity (25%35%), with reservoir pressures and temperatures that will maintain injected CO2 in a supercritical state and are near conditions required for miscibility of CO2 in the oil. The activities at Bell Creek will inject an estimated 1.1 million tons of CO2 annually, most of which will be permanently stored. In order to meet both PCOR Partnership and Denbury project objectives, a new observation well was drilled between injection and production wells in the portion of the field that will first undergo CO2 EOR operations slated to begin early in 2013. The positioning of the well allowed for the collection of a modern, robust data set to enhance ongoing geologic characterization activities and will provide access for a downhole monitoring program that will not interfere with oilfield operations.View/Download Document
