Ormat Nevada is starting flow and injection tests of two geothermal wells at Mammoth Lakes in California, to explore future contribution to geothermal power generation of the field.

As reported from California, Ormat Nevada Inc. has completed preparations for a 30-day flow and injection test of two existing geothermal wells near the Town of Mammoth Lakes in California.

Testing is to start today, having been approved by the Bureau of Land Management of the Department of the Interior, as we reported earlier.

With the tests, Ormat wants to collect data to determine the potential of production and re-injection of the two wells and the possible contribution to the overall geothermal production in the area.

In a coordinated effort, the U.S. Geological Survey and the Mammoth Community Water District will simultaneously be collecting monitoring data from nearby groundwater wells.

“Because this test has the potential to produce measurable responses in the hydrologic system, it provides a great opportunity to monitor potential responses in both the deep geothermal reservoir and the shallower groundwater reservoir,” stated BLM Bishop Field Manager Steve Nelson. “I truly appreciate the commitment to a coordinated monitoring approach that Ormat, U.S. Geological Survey and Mammoth Community Water District have shown in preparation for this test.”
