US Geothermal, through its subsidiary USG Oregon, has drilled and tested the NHS-8 well at the Neal Hot Springs geothermal project located in eastern Oregon.

The well encountered the reservoir zone at 3,604ft and flowed under artesian pressure at a rate of 2,770 gallons per minute (gpm), with a production temperature of 287.5 degrees Fahrenheit.

Two existing production wells have previously been drilled and tested at the Neal Hot Springs project.

Well NHS-1 intersected the reservoir at 2,287ft and flows under artesian pressure at a rate of 2,315gpm, with a production temperature of 286.5 degrees Fahrenheit.

Well NHS-5 encountered the reservoir at 2,796ft and flows at a rate of 1,500gpm, with a production temperature of 286 degrees Fahrenheit.

Wells with a flowing temperature of 286 degrees Fahrenheit and a pumped flow rate of 2,000gpm to 3,000gpm are considered very viable to substantiate commercial power generation, the company said.

A fourth production well, NHS-2, is being drilled at a location in between NHS-5 and NHS-8, and is currently at a depth of 1,188ft with a target depth to the reservoir of 3,220ft.

US Geothermal is a renewable energy company focused on the development, production and sale of electricity from geothermal energy, and USG Oregon is owned 80% by US Geothermal and 20% by Enbridge.
