To interpret well log data for formation evaluation, you parse LAS files or ASCII curve tables to calculate Vsh, porosity, and Sw, which identifies pay zones and reservoir fluids. This process generates a structured reservoir summary for decision-making.

Yes, you can use pasted LAS 2.0 or 3.0 file content to calculate petrophysical parameters like Sw and porosity. The workflow parses depth and curve units, performs quality checks, and applies Archie-style equations with explicit formulas to derive water saturation and handle gas effects.

Identifying net pay and fluid contacts from well logs involves applying Vsh, porosity, and Sw cutoffs to calculated petrophysical parameters. The interpretation suggests probable OWC, GOC, or GWC contacts with graded confidence levels while flagging low-quality intervals affected by washout.

Yes, this formation evaluation workflow handles tabular ASCII curve data exported from Petrel or Techlog, alongside LAS files and verbal curve descriptions. It parses standard open-hole and specialized log suites to perform quantitative petrophysical analysis across various data formats.

When well log curve data has washout or tool issues, interpretation limitations include reduced confidence in calculated porosity and water saturation values. The workflow explicitly quality-checks depth and curve units to flag these low-quality intervals, preventing inaccurate pay zone identification.
