Abstract
Scale incidence on production pipes of Cerro Prieto geothermal wells is a problem and occurs frequently but has been dimished by selection of the main productive strata or using orifice restrictions at the wellhead discharge. This last technique made in some new wells that have 120 bars pressure at wellhead. 150 wells have been drilled with the deepest exploration well being 4,300 m. The drilling for exploration and production wells continue at the present time. Around 100 x 10/6 tons of water steam mixture is extracted every year, 40% is separated steam which is used to three geothermoelectric power stations having a total of 620MW o installed capacity.
