HyTerra Commences Production Testing at McCoy-1 Natural Hydrogen Well in Kansas

HyTerra has commenced production testing operations at its McCoy-1 well within the Ridge Play of the Nemaha Project in Kansas, marking the company's first attempt to evaluate whether a HyTerra-operated well can sustain measurable natural hydrogen and helium production. 

The production testing campaign is expected to run for approximately three to four weeks and is designed to assess the well's performance by measuring gas composition, flow rates, pressure behaviour and overall reservoir characteristics. Certain gas samples will undergo laboratory analysis following field operations, with full interpretation of results expected by the end of September 2026. 

McCoy-1 contains two separate target zones, each of which will be tested independently. The results will help determine the well's producibility while providing data to guide future appraisal activities, including possible completion optimisation, additional testing or further drilling across the Ridge Play. 

Primary contractors have mobilised to site, with the work-over rig and testing equipment now installed and operating under HyTerra's supervision. The testing program includes controlled flow testing, gas sampling, continuous pressure monitoring and collection of reservoir and fluid data. 

The McCoy-1 program represents an important transition for HyTerra as it moves beyond exploration and drilling into reservoir appraisal. Production testing is a critical stage in evaluating whether a hydrogen accumulation can sustain measurable flow, providing the technical information required to assess future development options across the company's broader Kansas acreage.
