Sweet spot maps for geologic hydrogen and helium in Texas

The maps on this page are based on current estimates as of February 2026 and may be updated regularly by the Bureau of Economic Geology as additional data become available and new detection and estimation methods are applied. They are intended to highlight prospective areas at a regional scale and are not meant to be used directly for drilling decisions; any such decisions require further detailed, local-scale analysis.

The natural hydrogen and helium maps incorporate the spatial distribution of potential source rocks, reservoirs, seals, and the timing of deposition. The stimulated hydrogen map incorporates the spatial distribution of potential source rocks along with favorable formation depths and present-day temperatures that support enhanced serpentinization reactions. A detailed account of all inputs and methodologies will be published in a 2026 Report of Investigation by the Bureau of Economic Geology.
