connections and blanks in the wire-wrapped screen liner. For each of the two profiles presented, Flo-Log has shown zone-by-zone and cumulative representations of the injection rate profiles on the log. Conclusions from the logging results are summarized as follows: 1. The pre-injection shut-in temperature log indicates a distinct residual cooling anomaly within the perforated interval due to cooling by fluid lost to the formation during circulation and gravel packing. The profile shows clearly that the fluids were confined vertically below the top perforation at 4,234 ft. 2. The injection profile at each rate, as interpreted by Flo-Log, is shown on the log. The profiles show that essentially all the perforated intervals down to about 4,500 ft are taking water. The sand at 4,312 ft - 4,326 ft takes a disproportionately high percentage of the water and, therefore, must have a higher permeability than the others. 3. The R/A tracer check at the 5-in. liner top indicated no leakage. 4. The temperature profile which was logged 45 minutes after the start of injection (referred to as the "dynamic temperature" on the log) exhibits a rapid increase in temperature below 4,500 ft, confirming indications of the spinner logs that very little water is exiting through the lower two sets of perforations in the 5-in. liner. The temperature at 4,000 ft is 76°F on this log, but two later readings taken from the digital readout in the logging truck were 70°F and 72.3°F. On this basis, an "average" injection water temperature of 72°F was chosen as representative for determining fluid properties used in the pressure transient analysis. 5. The spectral noise log in the interval 1,200 ft - 500 ft gives no indication of fluid flow behind casing. Mesquite Group, Inc. -22
