TGS, a leading global provider of energy data and intelligence, announced two new regional seismic products designed to support exploration and appraisal activities across Alaska's North Slope and Arctic frontier. The new offerings, Great Bear Merge 3D and Alaska Regional 2D-Cubed, leverage TGS' extensive data library and advanced imaging capabilities to provide customers with broader regional subsurface insight across one of the world's most prospective hydrocarbon regions.

The Great Bear Merge 3D project combines multiple legacy seismic surveys into a seamless regional dataset covering approximately 1,366 square miles across Alaska’s North Slope. Reprocessed using modern imaging technologies, including full-waveform inversion (FWI), the project delivers improved data quality and continuity across historical survey boundaries, providing customers with a consistent regional framework for evaluating exploration and development opportunities.

The Alaska Regional 2D-Cubed project complements the 3D offering by integrating approximately 667,640 square kilometers of seismic data from across the North Slope, Beaufort Sea, and Chukchi Sea into a single, regionally consistent interpretation volume. By combining legacy 2D and 3D seismic data through a unified processing and imaging workflow, the project creates a continuous subsurface framework that enables basin-scale screening of remaining onshore recoverable reserves and additional opportunities in the Beaufort and, particularly, Chukchi Seas, connecting the multiple oil discoveries offshore to the commercially successful Permian-Cretaceous stacked plays onshore.

Together, these projects provide customers with access to a more complete regional understanding of Alaska’s evolving exploration landscape, helping to support acreage evaluation, prospect identification, and strategic decision-making.

David Hajovsky, EVP of Multi-Client, said: “As industry interest grows across Alaska’s onshore and offshore basins, customers are increasingly seeking a regional perspective that extends beyond individual surveys. These new products connect decades of seismic data into unified regional frameworks, helping customers better understand basin-scale geology and identify opportunities across the region’s evolving exploration landscape.”

The new products further strengthen TGS’ position as a leading provider of subsurface intelligence in Alaska, where the company maintains one of the industry’s most extensive seismic data portfolios.
