The completion in the lower portion of the Domengine was successful, leaving sands <br /> above 4,166 ft available for future recompletion. Representative Domengine water samples were <br /> collected during production of the well, and the total dissolved solids content was determined <br /> to be 14,066 mg/1. Injection test results indicated capacity adequate for water disposal at the <br /> nominal design rate of 150 gpm with a wellhead pressure of about 265 psig. <br /> Temperature, tracer and noise logs confirmed that the well has good mechanical integrity, <br /> with no movement of injected water above the completion interval and no other interzonal flow. <br /> Included in this report is the analysis of a leak-off test which was performed in the <br /> confining layer (Nortonville shale) at the shoe of the 7-in. casing during drilling operations. The <br /> formation was tested at pressures up to an equivalent gradient of 0.65 psi/ft with no indication <br /> of formation breakdown. The leakoff test was terminated before reaching breakdown pressure, <br /> so the results did not define an upper limit on injection pressure. Based on other test results in <br /> the Nortonville and an appropriate "safety factor", a recommended maximum injection wellhead <br /> pressure of 975 psig was derived. <br /> 2.0 INTRODUCTION <br /> This report documents completion and testing activities of the NCPA Lodi STIG #1 <br /> injection well. The well is intended for disposal of waste water from a steam injection gas <br /> turbine power plant which NCPA plans to build near the City of Lodi's White Slough Water <br /> Pollution Control Facility. The nominal design injection capacity requirement is for 150 gpm <br /> of waste water from the power plant. <br /> Mesquite Group, Inc. "2 <br />
