Locating Remaining Oil in a Mature Waterflood: A Case History

摘要

The Walnut Bend Field was discovered in 1938 and consists of over 70 Pennsylvanian channel sands draped over an elongated, anticlineal structure approximately 3 miles long and 1.5 miles wide. The main body of the field had produced over 99 MMBO by 1999 when a field revitilization project was initiated. This project was a success, both technically and commercially. The success of this program was due in large part on a new volumetric-balancing technology that provided accurate present day oil in place maps. Some of the highlights of this project are:·80% accurate prediciaon rate of current day hydrocarbons·1,080,000 bbls of reserves added·35% increase in production·Comprehensive multi-year revitalization plan.
