Exploration Activity: Development Wells At Long Valley Caldera Geothermal Area (Suemnicht, Et Al., 2007)
|Exploration Activity Details|
|Location||Long Valley Caldera Geothermal Area|
|Exploration Technique||Development Wells|
|Activity Date||2005 - 2006|
Declines in the production temperature and flow rate of the Casa Diablo field between 1993 and 1995 prompted the construction of the Basalt Canyon Pipeline later in 2005 to support the MP-I plant with additional fluids from wells 57-22 and 66-25 near Shady Rest to the east (completed in 2006 to approx. 500 m depth).
Higher temperature (180°C) fluids from these wells supply the Mammoth-Pacific facility with approximately 4,000 gpm of supplementary production flow for a total sustained flow rate of 12,000 gpm to the geothermal power plants.
