Physical Location of Hole: On the resurgent dome of Long Valley Caldera, in eastern California
Scientific Significance: The Long Valley Exploratory Well (LVEW) was drilled to assess the potential of a deep geothermal resource beneath the resurgent dome, help improve assessments of volcanic risk from major or minor volcanic eruptions emanating from the central caldera, and provide a “hole of opportunity” for testing drilling instruments and technology.

Funding Agency: USGS
DOSECC Drilling System Used: DOSECC Hybrid Coring System
Number of Holes Drilled: One, deepened the existing “LVEW”

Maximum Depth Reached: 9,831 feet
Number of Coring Days: 51
Average Footage per day of Coring: 52.1 feet/day
Challenges Met: Successfully field tested DOSECC Hybid Coring System
