A copy of the latest radioactive tracer run and a brief discussion of the results. <br /> 5.0 Planning <br /> The radial flow portion of the test is the basis for all pressure transient calculations. <br /> Therefore the injectivity and falloff portions of the test should be designed not only to reach <br /> radial flow, but to sustain a time frame sufficient for analysis of the radial flow period. <br /> General Operational Concerns <br /> • Adequate storage for the waste should be ensured for the duration of the test <br /> • Offset wells completed in the same formation as the test well should be shut-in, or at a <br /> minimum, provisions should be made to maintain a constant injection rate prior to and <br /> during the test <br /> • Install a crown valve on the well prior to starting the test so the well does not have to be <br /> shut-in to install a pressure gauge <br /> • The location of the shut-in valve on the well should be at or near the wellhead to <br /> 4 <br />
