Free diagnostics
Working tools, not a demo. They run in your browser: the numbers you paste are not sent anywhere, and there is no account, trial timer, or watermark on the answer. Use them on a real test today and judge us on whether the answer holds up.
Field-pace pad & stage calculator
Plan the pad before the crew arrives: stage slurry volume and pump time, the real cycle time between stages, pumping days, water and sand hauled, and whether the perforations hold a limited-entry split at your rate.
Type wells, stages, clusters, perfs, rate and loading. Answers update as you type.
DFIT & step-down interpreter
Classify the pre-closure regime from a shut-in pressure decline, and split the step-down pressure drop into perforation friction and near-wellbore tortuosity — with the exponent sensitivity shown rather than hidden.
Paste time vs bottomhole pressure, or rate vs pressure drop.
Log auto-tune
Drop in a log or lab CSV, map the columns, and fit the temperature trend and pressure calibration points. Bad rows are named and dropped, never filled in.
Paste or upload a CSV; column mapping is suggested for you.
The same rules as the paid product
If the data cannot support an answer, these tools say so instead of printing a confident-looking number. Where a result depends on an assumed exponent or a fitted trend, you see the assumption and the spread it causes.
Both tools export a Verified Design Record: one file with your inputs, each result marked solved or estimate, the residual, every refusal, and a fingerprint. Anyone can check it at /verify without an account.
The full platform — design, sweeps, pad studies, records — is private and opens by request.
