Together WIS and Well-Sense offers FiberLine Intervention (FLI) tools and services globally for geothermal applications. FLI is a low-risk wellbore surveying solution that rapidly delivers high-quality insights. It is often employed in surveys where other options prove unsuitable due to well accessibility, location, cost, application challenges, data requirements, temperature or speed of response.


Wellbore Integrity Solutions in partnership with Gunnar Energy Services delivers high-end relative wellbore positioning services often required for closed-loop geothermal applications.
We provide customized fit-for-purpose magnetic ranging solutions for precise first-attempt wellbore intersections. Our team of technical experts has been at the forefront of ranging technology and application since its early stages. We have been involved in the first geothermal closed-loop construction in history and are now offering the new generation of the most robust ranging technology suitable for harsh geothermal drilling environments.


ML Technologies and WIS offer a new approach to multi-lateral drilling for geothermal operations, whether the type of well is a re-entry, new drill, or a combination of both.
The new multi-lateral technology, designed for simple interventions, has been globally field-tested and provides up to 40% cost savings for drilling. The ML Technology tools are ideal for operating in high-temperature wells for both open-hole and cased-holed wells. The system is also particularly suited for increased high-pressure rates during fracturing operations.
