What petrophysical models are included in the workflow?

The workflow covers Vshale calculation (linear/Larionov), porosity from density/neutron, and water saturation using the Archie equation.

How does it handle noisy or inconsistent log data?

The workflow includes a dedicated QC stage using the 'welly' library to despike logs, identify washouts, and normalize values before analysis.

Does this skill support DLIS files?

Yes, it utilizes the dlisio library to handle modern DLIS data frames alongside standard LAS files.

Can I visualize the results in 3D?

Yes, the skill integrates PyVista for 3D well path visualization and property volume rendering for fence diagrams.

Data Science & ML

Automates the end-to-end formation evaluation pipeline from raw LAS/DLIS data to petrophysical analysis and 3D visualization.

This skill provides a comprehensive geoscience workflow for evaluating well log data using specialized Python libraries. It guides Claude through loading LAS or DLIS files, performing data quality control with welly, calculating key petrophysical parameters like Vshale, porosity, and water saturation using petropy, and generating lithology classifications with striplog. Whether you are building a reservoir model or performing a quick log QC, this workflow ensures consistent application of petrophysical best practices and enables advanced 3D visualization of well trajectories and properties.
