Exploration Activity: Cuttings Analysis At Coso Geothermal Area (2006)

Exploration Activity Details
Location Coso Geothermal Area
Exploration Technique Cuttings Analysis
Activity Date 2006
Usefulness not indicated
DOE-funding Unknown

Exploration Basis
To determine the geology of Injection Well 46A-19RD
Well 46A-19RD, located in the southwestern portion of this field is currently the focus of a DOE-funded Enhanced Geothermal Systems (EGS) project. Petrologic and petrographic investigations of the well show that quartz diorite and granodiorite are dominant lithologies. Dikes of granophyre, containing phenocrysts of plagioclase, potassium feldspar, and quartz were encountered at approximately 1438-1457 m and 3459.5-3505.2 m.
