Geological Data

Valuable insights for the best subsurface understanding

The world's largest library of well logs and basin models

TGS offers the world's largest collection of digital well log data with 15 million individual products spanning over 120 years. This data is sourced from public and non-public sources and digitized through a standardized and meticulous QC process. Our interpretive products encompass 21 North American basin models and are created by our in-house geologists using a consistent interpretation method. All TGS geological data is ready-to-deliver or made-to-order through R360TM or the TGS Data Lake API (including OSDU).
