The objective of this research was to develop methodologies of interest to the geothermal
industry to estimate critical parameters needed to characterize the fracture network …

Seismicity in the vicinity of an Enhanced Geothermal System (EGS) demonstration project in
the Northwest Geysers at the Prati 32 (P-32) injection well and the Prati State 31 (PS-31) …

This DOE GTO funded project was a collaborative effort between Array Information
Technology and the University of California at Berkeley. The project goal is to improve …

The Geysers geothermal field is one of the most seismically active regions in northern
California. Most of the events occur at shallow depths and are related to stress and …

Seismicity associated with geothermal energy production at The Geysers Geothermal Field
in northern California has been increasing during the last forty years. We investigate source …

Abstract At The Geysers geothermal reservoir in northern California, evidence strongly
suggests that activities associated with production of electric power cause an increase in the …

Source mechanisms of 1697 microearthquakes at the Northwest Geysers, and 985
microearthquakes at the Southeast Geysers geothermal fields are investigated using a …

We analyzed seismicity near the EGS development at The Geysers, CA Prati-32 injection
well to evaluate the development and the physical attributes of a subsurface fracture …

Microearthquakes have come into high public awareness due to being induced by the
development and exploitation of enhanced and natural geothermal fields, hydrofracturing …

Conclusions Understanding induced seismicity in a geothermal system can help to
characterize the geometry, extent and conditions of the reservoir, and to assess the potential …
