Paper: A Practical Method Of Monitoring Stimulation Fluid Entry Into Potential Producing Zones

Agnew" has proposed that temperature be utilized as a method for obtaining knowledge of the portion of a reservoir which has actually been stimulated. This particular method of evaluating frac and acid treatments has been utilized for several years. Additional evidence for the use of radioactive materials with temperature has recently led to the utilization of techniques involving the use of RA materials in conjunction with temperature, which lends a more quantitative perspective to treatment design and interpretation. This is particularly true when the combined techniques are used in conjunction with selective staging of fracturing and acidizing treatments.
