The world's largest library of well logs and basin models
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).
Source Logs
Our industry-leading library of subsurface data includes global coverage of rasters, digital logs, and stratigraphic models, providing valuable insights for the best subsurface understanding.
- 23% more rasters than state agencies
- 5x more digital wells onshore, 7x more digital wells in key basins
- Over 60 types of well logs:
- Standard: GR/SP, RES, DEN, NEUT, SON
- Specialty: MUD, LITH + comments, composites, check shot, porosity, etc.


Stratigraphic Models
We offer interpretation of high value formation tops for unconventional basins.
-
Stratigraphic framework interpreted by experts across 21 North American basins
-
Consistent set of formation top picks defined to precise stratigraphic units with optimal production statistics
- Detailed report for each model
- Geologic history
- Production statistics
- Interpretation and QC workflow
- Basis for top picks
- Regional cross sections
- Attribute Volumes:
- Constructed from formation tops integrated with BHTs from TGS' Stacked Headers
- Cubes Available: Temperature, Mud Weight, Total Organic Carbon (TOC)
Stacked Headers
Our stacked headers provide quality log parameters for top-to-bottom log correction and analysis for every run.
- Digitized log header information from all runs instead of only the deepest
- Extensive quality control, ensuring outliers are reviewed and rectified, when necessary, with the focus on providing the data as logged
- Easy consumption within projects
- Including, but not limited to:
- Wellbore diameters
- Temperature measurements
- Drilling fluid properties
- Mud resistivity variations
- Casing characteristics
