Sage Geosystems and Halliburton Bring Oilfield Discipline to Next-Generation Geothermal Sage Geosystems has selected Halliburton to provide cementing and stimulation services for Project Vector, its next commercial-scale Enhanced Geothermal Systems (EGS) facility at Ormat Technologies’ Blue Mountain power plant in Nevada. The partnership is a practical test of a central idea in the emerging geothermal industry: that oil and gas expertise—especially in wells, fluids, reservoir engineering, and field execution—can help turn promising geothermal technology into dependable, repeatable power infrastructure. Project Vector is more than another geothermal pilot. It is Sage’s attempt to prove that its proprietary EGS approach can be deployed beyond a single demonstration site, at commercial scale, and across varied geological conditions. Halliburton’s role in well integrity and reservoir stimulation therefore matters not only to one Nevada project, but to the broader question of whether enhanc...
Endurance Energy Tests the World's First Subsea Geothermal Well: What the Axial Seamount Demonstration Really Proved What if geothermal energy did not need a power plant on land? What if electricity could be produced directly from the Earth's heat beneath the ocean, with generators sitting on the seafloor and sending power to coastal grids? On October 19, 2026, Seattle-based startup Endurance Energy announced a major step toward that idea. The company said it had drilled and completed the world's first subsea geothermal well and placed a 3-ton test power plant nearly a mile beneath the Pacific. It also reported net-positive electricity from heat at an active underwater volcano, according to its announcement on PR Newswire. The headline numbers are modest. The Adélie prototype produced more electricity than it used for about 8.7 seconds. During that time it delivered a median net output of about 2 kilowatts and a peak of 16.5 kilowatts. One detail matters more than any other...
