Evaluating Water Control Problems with Well Logs on the West Coast

WYATT, DENNIS, Halliburton Energy Services, Bakersfield, CA

Both open and cased-hole well logs can be very effective for diagnosing causes of unwanted water or gas production. Often, the log data needed to diagnose the water source already exists in well files or needs minimal supplemental logs to be run. Casing leaks, cement channels, coning, completing too close to moveable water or simply watering-out of the reservoir can easily be identified from common logs. Evaluating the effectiveness of water control treatments with cased-hole logs can help determine whether a treatment was successful, failed completely or simply needs a remedial retreatment to accomplish the original goals. Specific applications of various well logs will be discussed with examples illustrating their use and interpretation.
