Abstract
Since 2000, the Federal Commission of Electricity (Comision Federal de Electricidad or CFE) began to use the matrix acidizing technique to improve the production / injection capacity of wells in geothermal fields in Mexico. Since that time, 13 production wells and 4 injection wells have been acidized. Savings as a consequence of the gain in production and injection capacity was found to be equivalent to the cost of 11 new production wells and 2 new injection wells. In this paper, the successes and failures realized when choosing the acid mixture, volumes and targets in every well are explored, and the overall results of the application of this technique are discussed.
