Bell Creek Test Site - Simulation Report - Plains CO2 Reduction Partnership Phase III Task 9 - Deliverable D66 Update 2
The PCOR Partnership is working with Denbury Resources Inc. to evaluate the effectiveness of large-scale injection of CO2 into the Bell Creek oil field for CO2 enhanced oil recovery (EOR) and to study long-term incidental CO2 storage. Discovered in 1967, the Bell Creek oil field in southeastern Montana has undergone primary production (solution gas drive), waterflooding, and two micellarpolymer pilot tests. About 37.7% of the estimated 353 million barrels (MMbbl) of original oil in place has been produced to date. It is anticipated that approximately 30 MMbbl of additional oil will be produced through CO2 EOR in this field. With the goal of providing a comprehensive assessment of incidental CO2 storage behavior, members of the PCOR Partnership have initiated a modeling and numerical simulation program to 1) characterize and model the study area using advanced geologic modeling workflows; 2) develop a robust pressure, volume, and temperature model to predict miscibility behavior of the CO2Bell Creek crude system and to aid in compositional simulation; 3) history-match the constructed dynamic reservoir model; and 4) utilize predictive simulations to aid in monitoring long-term behavior of injected CO2.View/Download Document
