Immutable sample workflow
Archie Water Saturation
Run one fixed clean-sand interval calculated on the server. The public demonstration accepts no resistivity, porosity, saturation exponents, temperature correction, shale properties, uploaded logs, or other customer data.

A clean-formation baseline
Archie saturation provides a standard clean-rock baseline using formation resistivity, water resistivity, porosity, and empirical exponents. Petrophysicists compare the result with geology, core, capillary pressure, and fluid evidence.
Interpret your log data
The paid suite supports controlled interval inputs, temperature handling, alternative saturation models, chart-ready curves, and engineering review. Customer logs and model choices remain outside this fixed example.

Archie assumptions may not represent shaly, conductive-mineral, fractured, mixed-wet, or complex-pore systems. Validate constants and water resistivity by zone, reconcile environmental corrections, and compare against independent saturation evidence.
