Well log interpretation that stays on your machine
A browser-based petrophysics workspace for loading LAS and DLIS well logs, running Vsh through net pay in structured views, and staging zone averages for Volumetrics—without uploading your log files or saved cases to our servers.
Formation Evaluation saves projects to a folder you choose on your computer using the File System Access API: case JSON, LAS files, trend lines, and display templates live in that project folder. We do not store well log files or interpretation cases in Supabase. DLIS parsing runs on our server only to return LAS-shaped JSON to your browser—the uploaded file is not retained. When you bridge zone results to Volumetrics, the handoff stays in your browser (local module bridge). CSV import elsewhere on the platform follows the same browser-only pattern where enabled.
Confidentiality with the operator
Petrophysicists working under operator confidentiality terms often cannot send raw logs to third-party cloud storage. This module is designed so interpretation work remains on the device you control; sharing is manual (export project package or case files) when you choose to involve a teammate.
Workspace views
Each case moves through dedicated views—same order as the in-app View menu:
Log viewer — load LAS or DLIS, alias curves, QC, and apply display templates
Vsh workspace — shale volume from GR, SP, neutron–density, and related indicators
Porosity workspace — density, neutron, sonic, and combined models with shale endpoints
Sw workspace — Archie, Simandoux, Indonesia, and dual-water saturation models
Net pay workspace — cutoffs, coal handling, and net/gross flags
Crossplots — neutron–density, Pickett, Hingle, M–N, Buckles (BVW), and GR histogram
Results and sensitivity — zone tables, exports, and cutoff sensitivity
Bridge to Volumetrics
When zone averages are ready, stage NTG, porosity, Sw, and net pay for the Volumetrics module through an explicit in-browser handoff. You review the payload before confirming; nothing is applied silently downstream.
