Characterization and Time-Lapse Monitoring of a Combined CO2 EOR and CO2 Storage Project at the Bell Creek Oil Field Utilizing Pulsed Neutron Well Logging
The Plains CO2 Reduction Partnership is working with Denbury Resources Inc. (Denbury) and Schlumberger to carry out a time-lapse pulsed neutron well logging (PNL) campaign as part of an iterative approach to site characterization, modeling and predictive simulation, monitoring and risk assessment at the Bell Creek oil field to evaluate the efficiency of a large-scale injection of carbon dioxide (CO2) for simultaneous CO2 enhanced oil recovery (EOR) and long-term CO2 storage (Gorecki and others, 2012).Initial injection of approximately 50 MMscf/day of CO2 is anticipated to begin by mid-2013 as part of the combined CO2 EOR and CO2 storage project at the Denbury-operated Bell Creek oil field, which covers approximately 22,000 acres and contains over 450 wellbores. Discovered in 1967, the Bell Creek oil field in southeastern Montana has produced over 130 million barrels (MMbbl) of oil from the Lower Cretaceous Muddy Formation sandstone, which is approximately 4500? in depth. Original oil in place (OOIP) is estimated to be over 350 MMbbl. Through primary and secondary recovery, about 38% of the OOIP has been produced.View/Download Document
