LOGS DETERMINE WATER FLOW BEHIND PIPE IN ALASKA

DeWayne R. Schnorr Schlumberger Wireline & Testing Anchorage Several case studies from waterflood wells in Alaska illustrate the effectiveness of impulse oxygen activation logging to determine water flow in both injection and producing wells. The log provides a qualitative measurement of water injection and/or production rates by zone, in cased wells completed with either single or dual tubing strings. The technique has been used in Alaskan waterfloods since 1990.
