HOUSTON, Texas (29 September 2025) – TGS, a global leader in energy data and intelligence, today announced the completion of a comprehensive stratigraphic and petrophysical dataset for the Powder River Basin, marking a significant milestone in the company's Rocky Mountain data portfolio expansion.

This latest release caps TGS' 2025 Rocky Mountain initiative, which has systematically covered the Greater Green River Assessment and the Uinta, Piceance, and Paradox basins. The Powder River Basin dataset provides extensive subsurface intelligence across 4,390 wells with 33 stratigraphic tops and an impressive 73,106 formation picks – representing one of the most comprehensive geological interpretations ever compiled for this prolific energy province. The release includes detailed petrophysical interpretations and regional property maps, supporting both conventional energy development and emerging carbon management strategies.

Engineered for comprehensive regional analysis and operational excellence, this dataset enables:

  • Systematic stratigraphic correlation across the basin's extensive coal-bearing sequences and conventional reservoirs
  • Advanced petrophysical characterization of reservoir quality, including porosity, water saturation, and net-to-gross ratios
  • Basin-scale geological modeling capabilities for enhanced prospect generation and risk assessment
  • Integrated analysis supporting coalbed methane development, conventional oil and gas exploration, and carbon storage evaluation

"The Powder River Basin dataset represents the culmination of our most ambitious Rocky Mountain data expansion to date," said David Hajovsky, Executive Vice President of Multi-Client at TGS. "With over 73,000 formation picks across this energy-rich basin, we're providing the industry with unprecedented geological detail to support everything from hydrocarbon exploration to large-scale carbon sequestration assessment."

The comprehensive scope and technical precision of the Powder River Basin dataset addresses the full spectrum of subsurface challenges. Built for seamless integration with existing interpretation workflows, it provides a standardized geological framework for operators, service companies, and research institutions focused on maximizing basin potential across multiple energy sectors.

With the completion of the Powder River Basin dataset, TGS now offers unparalleled Rocky Mountain coverage, delivering integrated subsurface intelligence that supports the full energy transition spectrum – from optimizing traditional resources to enabling next-generation carbon management solutions.
