Although this pilot has yet to prove that an expanded carbon dioxide flood in the Rock Creek Big Injun reservoir would be economically feasible, the pilot has been technically successful in several aspects. First of all, the mechanical operation of the project has proceeded smoothly in comparison to similar projects in the industry. Through this work, much experience has been gained (both mechanically and in reservoir engineering) that may be helpful in future projects of this nature. Also, from the production response to carbon dioxide injection and the Shaffer OB-2 core analysis, the miscible carbon dioxide injection displacement mechanism is moving oil. The amount of oil to be recovered, the time required, and the amount and cost of carbon dioxide injection required to produce this oil will all have a very significant effect on the economics of this project. 3 figures.
