NCPNs objective for the well was to perforate and test sands in the lower portion of the <br /> Domengine formation and retain the option to perforate sands in the upper portion when and if <br /> the additional completion interval might be required for adequate injection capacity. <br /> 3.0 TEMPERATURE LOG AND PERFORATING <br /> On May 12, a shut-in temperature log and a gamma ray/casing collar locator (GR/CCL) <br /> correlation log were run. Depths of collars were correlated to the Halliburton Logging Services <br /> (HLS) openhole log run on May 7, 1993, and the 5-in. liner was perforated selectively in sands <br /> between the depths of 4,234 ft and 4,573 ft. The perforating was done with 11-gram jet charges <br /> at 4 shots/ft, 120° phasing, in 31/6-in. hollow steel carrier guns. By API test, these charges <br /> produce nominal 0.31-in. diameter holes with 18.9 inches of penetration. The perforating was <br /> done on May 12 and 13. The following intervals were perforated: (depths referenced to the <br /> HLS openhole log) <br /> 4,234 - 4,239 4,331 - 4,379 <br /> 4,244 - 4,254 4,390 - 4,411 <br /> 4,267 - 4,288 4,432 - 4,507 <br /> 4,296 - 4,306 4,528 - 4,538 <br /> 4,312 - 4,326 41567 - 41573 <br /> A diagram of the well as it was at the completion of perforating is shown in Figure 3.1. <br /> The first indication of a sand control problem occurred during the perforating. Sand fill <br /> was running into the wellbore during the perforating job and accumulated to a depth of 4,311 ft <br /> by the end of the job. At one point, sand fill precluded perforating one 21-ft interval (4,411 - <br /> 4,432 ft) of a major sand body. <br /> Mesquite Group, Inc. -3 <br />
