Well-log QC

A wireline log in; a quick-look pay screen out. A deterministic petrophysics engine computes Vsh, porosity, Archie Sw, and net pay, and guarantees no foot of reported pay sits on a washed-out hole or a missing curve; the model extracts the header, classifies each zone's fluid, and drafts the memo, with a petrophysicist as the final signer. Logs are crown-jewel subsurface IP an operator will not paste into a public-cloud assistant; here every token is served on-prem.
