Well Data Analytics

Well Data Analytics delivers decision-ready drillable inventory by integrating lease availability, spacing and pooling intelligence, and precise landing targets with zone-specific reservoir insight and reliable performance forecasts enabling teams to high-grade prospects, optimize well placement, and accelerate development decisions across the full lifecycle.

Learn More

Identify available acreage and build regulatory-compliant drillable inventory by integrating leasing, ownership, and regulatory filings from Oseberg into Well Data Analytics. Operators and strategy teams gain a clear view of where capital can be deployed, which opportunities are permitted, and how ownership and regulatory constraints impact development timing and portfolio risk.

Define precise target landing zones by combining regulatory-approved locations with formation-aware subsurface data, stratigraphy, rock quality, and log-derived attributes. This integrated view supports consistent well placement decisions, reduces geologic uncertainty, and improves the quality and repeatability of development programs across assets.

Forecast future well production and economics before drilling by unifying subsurface, production history, engineering, and cost data in a single analytics environment. Well Data Analytics supports capital allocation, inventory valuation, and development planning by delivering confident performance forecasts for undeveloped locations across basins.

Geological Data

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.

Learn More

Access one of the industry’s largest well log libraries, including depth-calibrated raster logs, digital LAS logs, mud logs, and check shot and velocity data. LAS+ delivers depth-shifted logs with standardized mnemonics, spliced wireline and LWD data, and removal of invalid curves to ensure consistency and quality. Analytics Ready LAS (ARLAS) expands curve availability by predicting missing log data and delivering full quad-combo equivalent suites, powered by TGS’s proprietary machine-learning models and curve enhancement workflows. With over 17 million raster logs digitized and 1.9 million LAS files, TGS provides a scalable foundation for basin-wide subsurface analysis.

Turn raw log data into actionable subsurface insight. Petrophysical Interpretation (PI) logs deliver core-calibrated attributes such as TOC, OOIP, and clay volume, while more than two million hand-picked formation tops and expert-interpreted stratigraphic frameworks across 21 North American basins ensure consistent regional interpretation. Log Curve Attribute (LCA) volumes transform discrete well measurements into continuous 3D basin-scale models that improve velocity model accuracy, accelerate and de-risk acreage targeting, delineate sub-seismic landing zones, and enhance multi-variate analysis. Available LCA volumes include Gamma Ray, Resistivity, Neutron, Density, and Sonic. TGS Core Data further strengthens subsurface modeling with unique, digitized core analysis datasets that enhance calibration accuracy and interpretation confidence.

End-to-end log digitizing and scanning services include indexing, validation, and conditioning to TGS standards or custom specifications. Subsurface data management solutions deliver secure, mastered, OSDU-compliant infrastructure purpose-built for well and geological data, ensuring seamless integration into enterprise and digital workflows.

Support carbon capture and storage initiatives with CO₂ storage suitability and capacity assessments across depleted reservoirs and saline aquifers. TGS datasets enable confident regional screening, storage evaluation, and long-term subsurface planning.
