Injectivity Test At Long Valley Caldera Geothermal Area (Farrar, Et Al., 2003)
Exploration Activity: Injectivity Test At Long Valley Caldera Geothermal Area (Farrar, Et Al., 2003)
|Exploration Activity Details|
|Location||Long Valley Caldera Geothermal Area|
|Exploration Technique||Injectivity Test|
|Activity Date||1999 - 1999|
A second injection test was run in October 1999, approximately 1 year after Phase III drilling of LVEW was completed to a final depth of 2997 m. Approximately 80,000 L of fresh water was used during the test, supplied from the adjacent 270-m-deep Santa Fe well. Cold water was injected at a rate of 3 to 5 L/s over a 2-day period, yielding an average injectivity value of 2 L/s/MPa.
