Enverus announced the acquisition of the A2D well log library and associated data products from TGS. The transaction adds what Enverus described as the world’s largest commercial well log database to its energy intelligence platform.
The acquisition expands Enverus’ subsurface data foundation with depth-calibrated logs, LAS files, formation tops, petrophysics, and proprietary coverage across major U.S. basins. Terms of the transaction were not disclosed.
A2D’s library includes more than 8 million depth-calibrated raster logs and 1.9 million digital LAS files spanning millions of wells across every major U.S. basin. This includes more than 5 million proprietary logs that Enverus said are not available from any public or regulatory source.
The transaction also adds more than 2 million hand-picked formation tops, petrophysical interpretations, basin temperature models, analytics-ready log curve attributes, and 3D log attribute volumes. Enverus said these capabilities will help customers move from single-well analysis to basin-scale characterization without switching platforms.
A2D Technologies began building the well log library in 1993. Over more than three decades, it became a trusted commercial source for subsurface data across major U.S. producing basins, including the Permian, Eagle Ford, Bakken, and Marcellus.
Enverus said combining A2D’s well logs, formation tops, petrophysical data, and basin-scale attributes with its production, completions, land, ownership, costs, economics, and analytics workflows will help customers reduce data preparation and improve cross-functional alignment.
The company also said existing A2D licensing and subscription arrangements will carry forward, so current customers should not experience disruption to access. Well data products will remain available as standalone subscriptions and through existing access platforms, while additional integrated capabilities across Enverus will be introduced over time.
The A2D acquisition follows Enverus’ recently announced acquisition of PDS Energy Information’s exchange assets. Enverus said PDS adds an operational network through which an estimated 80% of U.S. completions, production, and drilling data is exchanged, while A2D adds the subsurface record behind well planning, landing decisions, reservoir characterization, and asset development.
Together, Enverus said the PDS and A2D acquisitions advance its strategy of connecting the data energy companies use across subsurface, operations, production, costs, economics, asset valuation, and commercial workflows. The company described the result as a more complete energy decision platform spanning from rock to revenue.
KEY QUOTES:
“We have always believed energy data becomes more valuable when it is connected. A2D brings subsurface depth and quality that customers have trusted for decades. 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. That is the difference between a data library and an intelligence platform.”
Manuj Nikhanj, CEO of Enverus
“We built the A2D library into something the industry depends on, and this transaction ensures it keeps getting better. Our customers have always wanted to take this data further into their workflows. Enverus gives them the platform to do that.”
Kristian Johansen, CEO of TGS
