Analysis of temperature and pressure measurements and production data for Berlín geothermal field, El Salvador

Abstract

The Berlín geothermal field is one of two geothermal fields in exploitation in El Salvador, located approximately 110 km east of San Salvador, the capital city. Since 1968, thirty-eight wells have been drilled in the field. Sixteen of the wells are productive, nine are connected to the Berlín power plant, two are used as reinjection wells, in order to complete the reinjection capacity, and five wells are waiting to be connected to the third condensing unit. Temperature and pressure logs from the production wells have been analyzed. The main feed zones were identified and formation temperature and initial pressure profiles estimated. The temperature decline in the production wells was analyzed, using the temperatures profiles and considering the connection between the production zone and the reinjection into well TR-12A....
