Abstract
Chemical composition of fluids produced by wells from Cerro Prieto IV (CP IV) area of the Cerro Prieto Geothermal Field have different features among them. Since Cerro Prieto Geothermal Field is a liquid-dominant system, most of the wells from CP IV produce a mixture of fluids from a zone deeper than wells from other parts of the field. The chemistry of liquid samples is characteristic of a neutral and of the sodium chloride geothermal brine type. Recently, liquid samples from few wells from CP IV has shown pH below neutral; as well as changes in their chemistry. These changes in composition may be indicative of processes that are occurring in the system. According to production and chemical data at least two groups of wells may be differentiated and probably are associated to geologic features in the field.
