Exploration Basis

Injection tests of various waters was needed for an augmentation program started to maintain reservoir water levels.

Notes

Loss of water in the Dixie Valley Geothermal Reservoir due to evaporative cooling at the power plant resulted in the need for an injection augmentation program. The program started in 1997 and required obtaining water rights and conducting extensive tests of various waters for scaling potential. The new injection program utilized cold shallow ground water rich in Ca and Mg. In order to stabilize the geothermal reservoir an injection augmentation rate of about 30 kg/sec was needed. Monitoring of the shallow cold water aquifer has shown that it should be capable of supplying water indefinitely.
