The carbon dioxide injection aspect of the project proceeded smoothly except during supply shortages. An actual effective injection of only 31% rather than the estimated 50% has reduced the percent pore volume of carbon dioxide injected into the pattern area to well below the design volume. Therefore, additional carbon dioxide injection may be required to insure a fair evaluation of this displacement mechanism. To date, this pilot has given no evidence to indicate that a miscible carbon dioxide flood will fail to economically recover a significant amount of oil, provided a sufficient volume of carbon dioxide is injected.
