This report analyzes the successful low-pressure gas drive in the Keener sand of the Bonds Creek oilfield, Pleasants and Ritchie Counties, W. Va.) and predicts its future performance. Core analysis from two wells and electrical and radioactivity logs were used to evaluate the reservoir characteristics. Production records over a 37-year period indicate that over 240,000 barrels of oil have been produced from the Keener sand by low-pressure gas injection. Decline-curve analysis shows that 165,000 additional barrels should be recovered from 108 acres of productive sand by continuing this secondary-recovery method.
