Abstract
The present paper describes two specific applications of a semi-empirical model which can be used to generate information related to the chemical incompatibility of imported injection waters into a geothermal reservoir. The model is applied to predict the sulfate precipitations in two geothermal operations, namely the Mercer and Currier leases in the Imperial Valley, California. The foreign waters considered for injection are the Salton Sea, Colorado River and ditch water. The results of the study are described. Also, the ways of combating the problems that may arise due to chemical incompatibility are discussed. These types of evaluations can serve as guidelines for other geothermal operations.
