dlis

Python library for working with the well log formats Digital Log Interchange Standard (DLIS V1) and Log Information Standard (LIS79)

Open source digital rocks software platform for micro-CT, CT, thin sections and borehole image analysis. Includes tools for: annotation, AI, HPC, porous media flow simulation, porosity analysis, permeability analysis and much more.

Python package to read well logs and model geomechanical properties.

Open source, public notebooks for working with DLISIO

Reading and eventually writing DLIS/LAS/LIS/SEGY files in golang. Very much work in progress.... at the alpha level

An open-source Python package for writing DLIS files.

Automatic vug detection and quantification in ultrasonic borehole image logs, read directly from DLIS. All thresholds in millimetres and decibels, so a parameter set carries between wells.

A fast way to check and work with .dlis files.

Per-well dossier manifest generator for the Equinor Volve dataset, producing structured well-centric artifact indexes with de-duplication and cross-well reference detection.

ProEssentials WPF .NET 8 chart sample — wireline Variable Density Log (VDL) acoustic visualization with a contour-injection rendering technique that eliminates smearing on large datasets. Real FORGE 16A(78)-32 cement bond log data; DLIS conversion script included.

Codex skill for natural-language analysis of LAS, DLIS, and WITSML well logs

Parse RP66 V1 (DLIS) well-log binary files — in the browser and Node.js with zero runtime dependencies.
