SUMMARY; Initial MIT Evaluation; Powertech (USA) Inc.; <br />• Wellington, CO; Wellbore: IN48-33-PW1 <br />On July 23`d, 2009, an initial MIT was performed on wellbore IN08-33-PW 1. <br />Prior to installation of testing equipment, a visual inspection of the wellhead and surrounding work site for <br />hazards to field personnel and/ or hindrances to working conditions was conducted. <br />After satisfactory completion of the visual inspection, the borehole was then prepared for installation of the <br />testing equipment. The surface casing, spline, and o-ring were cleaned/ lubricated and the packers were <br />lowered to 470 feet bgs. The testing wellcap were then bolted to the wellhead flange and the packers <br />inflated with nitrogen to 550 PSI. Packer inflation pressure was monitored for approximately 15 minutes <br />and continually checked for leak-down. After satisfactory testing of the packer inflation pressure, the <br />borehole was then filled with water through a port in the wellcap with the relief valve remaining open to <br />allow air to escape. Upon completing of the filling of the borehole, the injection and relief valves were <br />closed to allow any air remaining in the fluid column to migrate to the wellhead. The remaining air was <br />bled off and the system pressurized with water. The wellhead flange pressure was held for approximately <br />• 30 seconds at approximately 105.3 PSI before the inlet valve was shut and the test begun. <br />At 1352 Hours on 23 July 2009, borehole IN08-33-PW1 begun the initial MIT test. After 15.1 minutes of <br />testing, approximately 8.0 PSI of leakdown occurred equating to approximately 7 percent of pressure loss. <br />IN08-33-PW 1 passed the initial MIT test with the requisite X10% leakdown in >15 minutes. <br />After completion of the initial MIT test, the relief valve was opened and the packers deflated, beginning the <br />falling head/ recovery test. After completion of the falling head/ recovery test, the testing wellcap was <br />removed, the packer was retrieved and the original wellcap re-secured. <br />/ D <br />Edward W.
