Title: Planning and design of additional East Mesa geothermal test facilities (phase 1B). Volume III. Appendices. [Petrophysical study of 7 wells]

Abstract

In the first of two sections of this report, Appendix A, results of a petrophysical study performed on seven wells in the East Mesa area of the Imperial Valley of California are reported. The wells were drilled on and around the geothermal anomaly that constitutes the East Mesa Field. The study was subdivided into two tasks, the first dealing with three recently drilled wells, the second dealing with four older wells that lie off the geothermal anomaly. The three new wells are: Republic Geothermal 38-30, Republic Geothermal 16-29 and Republic Geothermal 18-28. The older wells are: Magma Sharp, Border Barbara, American Petrofina No. 27 and Texaco Grupe-Engebretson. In each case the objective of the petrophysical study was to determine porosities, permeabilities and salinities in requested intervals, together with the selection of the best sand/shale discriminator. The computed results are reported in table and listing form to show average values of porosity, horizontal and vertical permeabilities together with gross interval, net sand, percent sand and darcy-feet tabulations, layered in 250' intervals throughout each well. The second section of this report, Appendix B, is devoted to details of the drilling prognosis for the three geothermal wells to be drilled by the Bureaumore » of Reclamation at their East Mesa site.« less
