Magnetic ranging technology advances speed, accuracy, and automation for geothermal wells
HOUSTON – Feb 25, 2026 – Halliburton (NYSE: HAL) today launched the RangeStar™ Geothermal Well Spacing and Intercept Service, a part of the family of RangeStar™ magnetic ranging services, a next-generation solution that supports geothermal development through faster, more accurate, and fully integrated well placement.
Designed for complex geothermal environments, the RangeStar Geothermal Well Spacing and Intercept Service delivers reliable performance that reduces uncertainty and simplifies operations. Rapid ranging determination reduces decision time from hours to minutes, supports detection distances up to 130 meters, and improves accuracy within formations and depths.
With the RangeStar Geothermal Well Spacing and Intercept Service, Halliburton redefines how geothermal operators approach well intercepts and magnetic ranging operations. The service brings together proven technologies in a unified solution designed to improve accuracy and strengthen overall well execution.
Configured as an all-inclusive bottomhole assembly, the service provides both short‑ and long‑distance detection in a single configuration, unlike traditional ranging approaches that require multiple tools. Faster ranging decisions and reduced tool complexity help operators lower execution risk and improve subsurface precision.
Developed with proven ranging and drilling optimization technologies, the RangeStar Geothermal Well Spacing and Intercept Service allows operators to acquire high-quality data closer to the bit while maintaining efficient hole cleaning and stable drilling conditions.
The RangeStar Geothermal Well Spacing and Intercept Service seamlessly integrates with Halliburton’s iStar® intelligent drilling and logging platform, the LOGIX™ automation and remote operations family of solutions, and the industry-leading iCruise® intelligent rotary steerable system. The service supports connected workflows, delivers a clear path to automation-driven ranging and remote operations, and positions the company at the forefront of automated geothermal ranging operations.
