| Abstract | Petrologic analysis of drill cutting samples from the Magmamax Nos. 2 and 3 and Woolsey No. 1 well in the Salton Sea Geothermal Field has resulted in the categorization of the sedimentary sequence. The cap rock extends to 325 m and unaltered reservoir rocks occur to approximately 900 m. The lowermost sequence is hydrothermally altered reservoir rocks. Laboratory measurements of core samples indicate a reduction in porosity with depth and fracture porosity appears to contribute to the total porosity of the system. The geologic picture that emerges from SP log correlation is that of a structural basin whose axis lies to the northwest of Magmamax No. 2. |
