New High-Temperature Downhole Fluid Sampler – A Major Step Forward in Geothermal Research and Sustainable Utilization By: Robert Buluma January 17, 2026 Alphaxioms Geothermal News Iceland’s geothermal resources have long been the cornerstone of the country’s energy independence, providing nearly 100% of space heating and a substantial share of electricity production from renewable sources. Since its establishment, the Icelandic Institute of Natural History’s geothermal division — today known as ÍSOR (Iceland GeoSurvey) — has placed strong emphasis on research, innovation, and the development of cost-effective technologies to meet the challenges of geothermal utilization. The latest milestone in this continuous effort is the successful development and field deployment of a high-temperature downhole fluid sampler, capable of collecting authentic reservoir fluid samples at extreme temperatures. What is the High-Temperature Downhole Fluid Sampler and Why Does It Matter? In convention...
