D028 Making Flooding More Effective - A Procedure for Mapping Subsurface Flo Paths P. Rollins* (Willowstick Technologies) SUMMARY This paper introduces a new method for mapping the flow paths crea flooding activities in mature oil fields. The new procedure uses the flooding substance with a low voltage low amperage audio-freq current. The current creates a distinctive magnetic field that and character of the flow occurring between the electrodes. The field is identified and surveyed from the surface using a highly sens procedure can pinpoint the location of blockages and other problem inexpensively than traditional methods which typically rely on the
