The World's Largest Library of Geological Data for the Oil and Gas Sector

Search, purchase, and manage geological data from the world's largest well log subsurface database in TGS R360. Click through millions of processed raster logs, digital logs, and geological interpretations in U.S. and international basins. Available to download directly or via the OSDU-compliant TGS Data Lake API.

Geological Data

Our comprehensive geological data provides clarity, precision, and strategic insights for the full exploration and development lifecycle.


TGS Well Data - Exploration


  • Depth-calibrated raster logs: Depth-calibrated and easily viewable digital representations from scanned well logs  
  • Digital LAS logs: 12-Curve log suites to provide the best essential log curves, digitized from top-to-bottom with curves of same name/description merged  
  • Mud logs: Data from the drilling engineer and well site geologist relating to the rock and hydrocarbons encountered  
  • Check shot and velocity data: Direct measurement of travel time between the surface and a given depth  
  • Petrophysical interpretations: Core-calibrated attributes incl. TOC, OOIP, clay volume and more 


TGS Well Data - Development


  • Well log digitizing and scanning services: Scanning, indexing, validating, digitizing, and conditioning well logs to the TGS standard and customized specifications  
  • Subsurface data management: Mastered, secure, and OSDU-compliant solution specifically for well data and geological data  
  • Interpreted tops and stratigraphic models: Structural grids, temperature models (BTM), and attribute volumes (predicted log responses, petrophysical properties); over two million hand-picked tops in 21 U.S. basins  
  • Carbon capture and storage: CO2 storage suitability and capacity assessment for depleted hydrocarbon reservoirs and saline aquifers
