Report: Chemical analyses and preliminary interpretation of waters collected from the CGEH No. 1 geothermal well at Coso, California

Abstract
The chloride-rich water obtained in 1967 from the shallow (114.3 m) Coso Hot Springs well No. 1 comes from a deep aquifer with a temperature at least as high as about 240 C and possibly higher than 275 C. Similar, but slightly diluted and cooled chloride-rich water enters the 1477-meter deep CGEH No. 1 well drilled in 1977 about 3.2 km to the west of the 1967 well. From the data in hand the Coso geothermal system appears to be a hot water type. The surface expression of fumarole and acid sulfate pools and shallow steam wells gives a false indication of an extensive vapor dominated system because upward convecting, boiling alkaline-chloride waters do not reach the surface.
