the radius of investigation, ri.,,. An expression for ri.,, was found in the literature and used in <br /> the calculations, which are outlined in Appendix D. From this analysis, permeability was <br /> estimated to be 72.6 md, which is a reasonable confirmation of the semi-log analysis. <br /> 9.0 INSTALLATION OF TUBING AND PACKER <br /> On June 9, 1993, injection tubing and a packer were installed in the well. The packer <br /> was set in the 7-in. casing at a depth of 3,342 ft KB and the tubing/casing annulus was pressure <br /> tested to 500 psi for 30 minutes. The pressure was bled off and the well was left shut-in, ready <br /> for injection service. Figure 9.1 is a diagram of the well, as completed. The tubing is 41/2-in. <br /> O.D., 10.5 lb/ft API K-55 LT&C R3, and the packer is a Baker Model AL-2 large-bore <br /> Lok-Set. <br /> Future injection capacity of the well as a function of wellhead pressure was estimated on <br /> the basis of the June 8 injection test data with calculated corrections for water density and <br /> pressure loss in the 41/2-in. tubing. In Figure 9.2, wellhead pressure is plotted for the three <br /> injection rates at which the most stable pressures were obtained during the June 8 injection test. <br /> A straight line fit of these points is also shown in the figure. The injection test was performed <br /> with 15,000 ppm TDS water from the storage tanks on site, and there was no tubing in the well <br /> at the time. To estimate injection wellhead pressure as a function of injection rate during future <br /> operation of the well, a curve was constructed by adding the following factors to the straight line <br /> approximation of the injection test data: <br /> Mesquite Group, Inc. -28 <br />
