Expro completes Enhanced Drilling acquisition, implications for geothermal MPD and RMR applications Image: a thematic picture of an offshore drilling company  Summary   Expro’s acquisition of Enhanced Drilling , bringing managed pressure drilling (MPD) and riserless mud recovery (RMR) into its global portfolio, is significant for geothermal developers and drilling teams. MPD offers fine-grained control of bottomhole pressure that directly addresses narrow drilling margins, lost-circulation risk, and inflow, underbalance events common in deep, high-temperature geothermal wells and engineered geothermal systems (EGS). RMR’s capabilities for capturing and recovering drilling fluids without a riser translate to lower logistics costs and reduced environmental footprint on shallow offshore or nearshore geothermal projects and onshore marginal sites where cuttings handling is constrained. For geothermal operations, integrating MPD and RMR can improve drilling efficiency, redu...

Eavor Remains Committed to Geretsried as Loop 1 Proves Closed-Loop Geothermal Technology at Commercial Scale CALGARY, Canada / GERETSRIED, Germany, image : The Eavor Geretsried Project   Company confirms flagship German project has validated Eavor-Loop™ technology, achieved major drilling cost reductions, and will serve as the foundation for global deployment through licensing and next-generation drilling innovation. Eavor Technologies has reaffirmed its commitment to completing the landmark Geretsried geothermal project, describing the development as a pivotal milestone not only for the company but also for the future of closed-loop geothermal energy worldwide. In exclusive responses provided to Alphaxioms, Eavor President and Chief Executive Officer Mark Fitzgerald confirmed that the company remains the operator of the project and is working closely with partners and stakeholders to complete the remaining development phases. "Eavor is currently the operator at Geretsried an...

Köln, Dellbrück Research Well, Probing the Massenkalk for Hydrothermal Geothermal Potential Image: A drilling rig at the Köln-Dellbrück geothermal research site, probing deep underground for hidden heat. Since late June 2026 a rotary drill bit has been descending at Thurner Kamp in Köln, Dellbrück, marking the start of a targeted research drilling campaign by the Geological Service of North Rhine, Westphalia, GD NRW. The exploratory borehole, planned to reach up to 1,000 meters, will test whether the region’s roughly 380 million year old limestone sequence known as the Massenkalk can act as a viable hydrothermal geothermal reservoir. For industry stakeholders, utilities and project developers, the drill program offers both immediate technical insights and strategic data to inform future geothermal development under the Masterplan Geothermie NRW. Why Köln, Dellbrück matters to geothermal development in NRW North Rhine, Westphalia is one of Germany’s most densely populated and industrial...

Kaishan , Halliburton Team Up on Advanced Geothermal, Green Fuel Projects Kaishan Group and Halliburton have deepened their cooperation with a strategic memorandum of understanding centered on advanced geothermal development, especially enhanced geothermal systems (EGS), along with green hydrogen and green ammonia opportunities. The deal builds on earlier Indonesia drilling work and signals a broader push to combine Halliburton’s high-end well-construction capabilities with Kaishan’s geothermal equipment and project-development platform. Partnership Background The relationship did not begin with the July 2026 memorandum. In February 2026, Halliburton said it had won a multiyear contract from KS Orka Renewables , part of Kaishan’s wider corporate group, to support geothermal well construction at the PT Sorik Marapi Geothermal Power and PT Sokoria Geothermal Indonesia projects in Indonesia. That work covered directional drilling, cementing, drilling fluids, and drill bits across several...
