Geochemical and Thermohydraulic Characterization of Some Production Wells of New Geothermal Project Las Pailas II in Costa Rica

Abstract

Las Pailas II Geothermal Field is new Project in Costa Rica that is the final stage of development and is scheduled to enter into operation by mid-2019, it is located in the foothills of the southern sector of the Rincon de la Vieja Volcano, and is next to Pailas I GF. Due the limitations to get the resource within the national park where the volcano associated is located, its operational design was proposed through the use of directional drilled wells that allow access to the resource in an underground way, also to preserve the environment and decrease the constructive impact were designed works taking full advantage of the building space, the project has 21 drilled wells, of which 12 are producers and 9 reinjectors. During 2018 the first productive evaluations of the wells of the field were carried out, in this work data of different wells of the PL-11, PL-12 y PL-13 platform are presented, where the geochemical and thermohydraulic characteristics of the area are exposed.
