MAMMOTH LAKES, Calif. August 23, 2017 – 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. The test was approved by the Bureau of Land Management Bishop Field Office, in coordination with the Inyo National Forest Mammoth Lakes Ranger District, earlier this month. Testing is scheduled to begin on Thursday, Aug. 24.

The purpose of the flow and injection test is to allow Ormat to collect data needed to determine the potential production and injection capabilities of the two wells and their potential contribution to the overall geothermal energy production strategy 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.”

The public will continue to notice increased activity and vehicle traffic along Sawmill Cutoff Road, between the town of Mammoth Lakes and Shady Rest Park, as crews conduct the test. Steam plumes rising from the test site, which is located just northwest of Shady Rest Park, will be visible to area visitors. All roads and recreational trails near the area are expected to remain open for public use during the 30-day test period.

The America First Energy Plan is an all-of-the-above plan that includes oil and gas, strategic minerals, and renewable sources such as wind, geothermal, and solar – all of which can be developed on public lands.
