Some Aspects Related to Chemicals Systems Used in the Exploitation at the Dr. Alfredo Mainieri Protti Geothermal Field (Formerly Miravalles Geothermal Field), Costa Rica

Abstract

The chemical systems used for the exploitation of producing wells in the Dr. Alfredo Mainieri Protti Geothermal Field (formerly Miravalles Geothermal Field) change over time, according to variations in geothermal fluids. New formulations of inhibitors of calcium carbonates, variations in doses according to productive conditions, changes in the chemism of fluids, costs, are some elements discussed in different sections. The neutralization systems have also changed according to the evolutionary conditions of the acid wells. Power generation at the Dr. Alfredo Mainieri Protti geothermal field currently depends on the utilization of systems for inhibition of calcium carbonate scale, as well as, acid-neutralization systems, in the field´s production wells. Some aspects are discussed under the appropriate sections.
