U.S. Geothermal Tests Production Wells at Raft Energy Project

摘要

U.S. Geothermal Inc., a renewable energy development company focused on geothermal energy in the Pacific Northwest, has begun a workover and flow test program on five existing energy production wells at Idaho's Raft River Geothermal Project. The testing uses funds from a $396,000 DOE Geothermal Resource Exploration and Definition Grant. When the company opened the wells this past spring "we had an immediate response in pressure and flow," which confirmed the wells' capacity, said Daniel Kunz, president of Idaho-based U.S. Geothermal. The production wells being tested produced artisan flow of 250 to 600 gallons-a-min-ute, and maintained wellhead pressures of 140 to 170 pounds per-square-inch. Fluid production temperatures from individual wells historically range from 270℉ to 295℉ (135℃ to 149℃).
