Our geothermal solutions help you stand the heat
As the dedicated global fluids-focused company – we know exactly how to keep your operation one step ahead of the unique demands of geothermal drilling.
Our longstanding focus of engineering water-based fluids systems enables you to sustainably and cost-efficiently develop geothermal wells. Leveraging our vast investment and experience of high-performance water-based fluids system solutions – field-proven in over 5,000+ oil & gas wells.
From our portfolio of industry-leading fluid systems and additives, we engineer the right solution for your geothermal application. We anticipate the challenging conditions of thermal instability, high fluid loss and fluctuating H2, He, CO2 and H2S that you may face – ensuring we are prepared to deal with them. Creating truly specialist solutions for a truly specialist industry.
Avoid lost circulation and reservoir damage
TerraTherm™ high-performance geothermal water-based fluid system has been proven in the field at extreme temperatures of up to 350 °C. Making it the choice for operators keen to proactively avoid the costly lost circulation and reservoir damage typically associated with drilling geothermal wells.
Sustainable fluid systems designed for geothermal applications
TerraTherm™ high-performance water-based geothermal drilling fluid system is carefully designed, stress-tested and validated in the field to withstand extreme temperatures in the world’s most challenging geothermal applications. The water-based system has an excellent environmental and sustainability profile that is ideal for the demands of this renewable energy source development. The system offers exceptional flexibility, and tailored formulations offer rig site augmentations keeping you one step ahead of unforeseen conditions like temperature fluctuations, unpredicted changes in lithology and well control events.

ITALY: ENEL GREEN POWER (1989-2019)
Newpark has drilled over 205,000 meters of geothermal wells in Italy since 1982 including areas with presence of H2S & severe losses. Our latest project involved drilling an ultra-hot geothermal well with BHST close to 600° C – exacerbated by the development of a high-pressure gradient that required a 1,6 sg MW – using Ilmenite as weighting agent to achieve the required MW without any sagging issues.
ICELAND: LANDSVIRKJUN (2009)
A local power company was operator of the Icelandic Deep Drilling Project consortium driven by Statoil IDDP-1 well – Krafla field. The hottest and most productive geothermal well in the country required drilling through the first reservoir to meet the deeper one with critical BHST at 2100m. After successfully drilling through the basaltic formation the operator would now like to drill IDDP-3 well after feedback on our Descramble well experience characterized by critical BHST of over 550°C.
TerraTherm with optimized flocculation delivers results under strict German regulations
Overall waste volumes dramatically reduced and cost lowered with TerraTherm water-based drilling fluids.
Well delivered 20% sooner in challenging volcanic operation
TerraTherm high performance water-based geothermal drilling fluid system delivered well six days ahead of schedule.
