This report is the thirty-eighth report on the progress of the Rock Creek carbon dioxide project in Roane County, West Virginia. Injection of carbon dioxide was scheduled to begin in the fourth quarter of 1978. The need to eliminate the thief zone problem caused a three month delay. This problem was rectified, but contract negotiations for a carbon dioxide supply at an increased price will delay carbon dioxide injection further. Start-up of carbon dioxide injection is scheduled to begin in February 1979. The response to waterflood declined significantly during this quarter. The center producing wells are now producing near a 100% water cut, therefore, the waterflood portion of the project is basically over. Any significant oil production from now on will be attributed to carbon dioxide injection. Water injection continued without incident during the quarter. As of January 1, 1979, 1,604,617 barrels of water have been injected. Pressure fall off tests indicate a reservoir pressure of 1000 psig which is sufficient for miscibility.
