TGS, a leading provider of energy data and intelligence, today announced that it has closed the sale of its North American well data products business to Enverus, Inc. for a purchase price in excess of USD 100 million. The transaction consists of USD 100 million payable at closing, with an additional USD 15 million earn-out conditioned on milestones agreed between the parties.

A2D, a subsidiary of TGS acquired in 2002, operates TGS’ well data products business, including the North American well log library and associated data products. The business has formed part of the company’s North American onshore data offering and had revenues of USD 27 million in 2025, representing 2.9% of TGS’ reported multi-client revenues.

The divestment reflects TGS’ continued focus on portfolio optimization and capital discipline. With acquisitions of PGS, Magseis and ION Geophysical during 2022-2024, TGS has successfully built a strong market position in offshore basins around the world, with an integrated offering of leading offshore OBN and streamer technologies, the world’s leading multi-client library and advanced data processing. As a result, the company’s North American onshore geological business has become less strategic to TGS’ long-term priorities.

The sale enables the A2D well data products business to transition to an owner appropriately positioned to support its next phase of growth, including through a gradual evolution toward software-as-a-service offerings. TGS retains a license to use the A2D North American well log library for internal purposes, allowing for the continued enhancement of its seismic data products.

“This transaction represents an important step in sharpening TGS’ strategic focus and strengthening our balance sheet,” said Kristian Johansen, CEO of TGS. “We built the A2D well data products business into something the industry depends on, and we are pleased that it will be a good fit with Enverus’ business offerings and allow it to grow further. The transaction provides TGS a solid commercial valuation for this business, allowing us to enhance our focus on our integrated offshore geophysical service offering and improve our strong balance sheet, further supporting shareholder capital allocation strategies.”

Manuj Nikhanj, CEO of Enverus, commented: “A2D is the subsurface dataset the industry has relied on for 30 years. It now sits alongside the deepest operational, economic and commercial data in energy — including exchange networks through which an estimated 80% of U.S. production volumes are shared and more than $500 billion in annual transaction activity flows. Every major decision in energy touches the subsurface. Now that data connects to everything else we do.”

TGS intends to use the proceeds from the transaction to reduce net debt, providing increased flexibility to pursue higher capital returns to shareholders over time, in line with the company’s financial priorities and capital allocation strategy.
