| Summary: | Monitoring of the chemical composition of water and steam discharged from wells in exploited geothermal fields provides information on the response of the reservoir to the production load. Decrease in the Cl concentration in the discharged water indicates relative increase in recharge into producing aquifers of colder water but an increase in Cl indicates recharge from hotter zones. When a well discharge consists of components with different source temperatures, the consequence is discrepancy between geothermometry temperatures. The cause of discrepancy may also be variable departure from equilibrium for individual geothermometers. |
