Increase Geothermal Energy Generation Due to Matrix Stimulation Techniques in Mexico Geothermal Fields

Abstract

In Mexico as an other countries worlwide, matrix stimulations has been done since several years ago,with the main objetive of recover or increase the steam production and injection capacity in productions and injections geothermal wells. CFE(Comision Federal de Electricidad) which owns and operates four geothermal fields Los Azufres,Los Humeros, Las Tres Vírgenes and Cerro Prieto, has been done matrix stimulations in many wells with excelentes results in most of them. The geothermal energy contribution in the country energy matrix is around 2%, mostly generated by CFE, of the total generation by diferents technologies. This document presents the electric generation achive by the increase steam production rate in stimulations wells and its importance in the sustainable exploitation of geothermal fields.
