Enverus acquires TGS well log business in $100 million deal

(WO) — Enverus has acquired TGS' North American well data products business for more than $100 million, adding one of the industry's largest commercial well log databases to its energy intelligence platform while allowing TGS to sharpen its strategic focus on offshore geophysical services. 

The transaction includes $100 million paid at closing, with an additional $15 million earnout tied to agreed performance milestones.

The business, operated through TGS subsidiary A2D, includes North America's commercial well log library and associated subsurface data products. The unit generated approximately $27 million in revenue during 2025, representing about 2.9% of TGS' reported multi-client revenue.

For TGS, the divestment continues a broader portfolio realignment following its acquisitions of PGS, Magseis and ION Geophysical, which expanded the company's offshore seismic acquisition, ocean-bottom node (OBN), imaging and multi-client data capabilities.

"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."

TGS said it will retain a license to use the A2D well log library internally to continue enhancing its seismic products while using proceeds from the sale to reduce debt and support future shareholder returns.

For Enverus, the acquisition significantly expands its subsurface data offering by adding more than 8 million depth-calibrated raster logs, 1.9 million digital LAS files, more than 2 million interpreted formation tops, and over 5 million proprietary well logs spanning every major U.S. producing basin.

"We have always believed energy data becomes more valuable when it is connected," said Manuj Nikhanj, CEO of Enverus. "When logs, tops and petrophysics can be connected with production, completions, ownership, costs and economics, teams can move from understanding the rock to understanding the return."

Enverus said the acquisition will allow customers to integrate subsurface interpretation with production, drilling, land, ownership, cost and economic datasets within a single platform, reducing data preparation and supporting more advanced analytics and artificial intelligence workflows.

The acquisition follows Enverus' recently announced purchase of PDS Energy Information's exchange assets, further expanding the company's integrated energy data platform.
