Techlog new features

Techlog AI Import

Operators often rely on as little as 10% of the available data when making critical investment decisions for exploration or joint ventures. Most of the information remains locked in unstructured formats— images, PDFs, or scanned reports.

The new Techlog AI Import tool addresses this challenge by enabling geoscientists to directly import and process unstructured data, including legacy formats such as TIF, LAS, and old images. This capability streamlines data discovery and significantly reduces manual effort. The imported data becomes immediately available for quality control and publication to the OSDU® Data Platform, enhancing overall data accessibility and governance.

Techlog AI Log Prediction

This lightweight, AI-powered log prediction tool is built on a globally trained log foundation model. Developed with curated public data from more than 18,000 wells worldwide, it processes information without the need for a GPU.

Designed to accelerate and enhance subsurface interpretation, the log foundational model provides a strong baseline that users can tune both locally and privately with their own basin or asset data—selecting calibration wells, defining inputs and targets, and running the tuning process directly in Techlog software.

Once customized, the model can predict missing logs across other wells with high accuracy and minimal training data. In the case of acoustic data, many users require shear velocity for diverse workflows—this approach has been shown to reduce the median absolute error in a shear velocity prediction use case by 50% compared to traditional AI methods.

Future releases will extend access to customer-tuned models across other Delfi™ digital platform applications, including Petrel software—enabling seamless, scalable value across the subsurface workflow.

Techlog 3DP—Petrophysics for High Angle and Horizontal Wells

This module has long supported correction of log responses for geometry effects, improving accuracy of formation evaluation in high-angle and horizontal wells. Existing capabilities include automatic near-wellbore model initialization using dip sets and density image data.

Optimized for wells with near-parallel trajectory-to-layer intersections, this update strengthens the link between borehole image interpretation and petrophysical analysis.

With this release, users can now automatically initialize local layer geometry using ExpertDip zone images—generated from borehole image interpretations with Techlog’s ExpertDip plug-in.

This enhancement enables:

• Seamless integration of geological interpretation into petrophysical modeling.
• Streamlined model setup for high-angle and horizontal wells.
• More accurate and efficient multi-layer formation evaluation.
