Paper: Radioactive Placement Technique For Well Stimulation

Shortage of oil, rising prices and increased difficulty and expense in finding new reserves make it imperative to investigate techniques for further stimulation of wells, particularly wells with large open hole sections, or wells with poor cement jobs. With this in mind, a method was investigated that resulted in the control of the placement of stimulation fluids through the use of radioactive tracer material and Gamma ray detectors, which provided instant and continuous knowledge of the zone of entry during the entire stimulation process. This placement technique insures all zones of interest are stimulated without stimulating water bearing or other undesirable zones.
