| Abstract: | The Comisión Federal de Electricidad of Mexico and Lawrence Berkeley Laboratory of the United States are currently conducting joint investigations of the Cerro Prieto geothermal field, located approximately 35 km south of the city of Mexicali, Baja California, Mexico. Based on the geophysical well logs, transversal cross sections were constructed. This study consists mainly of correlating electrical markers observed in the logs. Temperature logs were also used to assist in the differentiation of what we call reservoirs A and B.In this article the stratigraphy observed in the cross-sections, the faults, and the identified producing layers will be described. Finally, the usefulness of this type of study for planning new wells, for selecting producing intervals, as well as for the development of the geologic model of the field will be presented. |
