Field-pace pad calculator
The numbers you need the night before: how long a stage pumps, how long the cycle really takes, how many days the pad runs, how much water and sand shows up, and whether the perforations can hold a limited-entry split. It runs in your browser as you type — nothing is uploaded and nothing is saved to an account.
The pad
The stage
0.56 fresh perfs, 0.85 once rounded
The day
Wireline, plug, swap, pressure test
Blank means hydraulic horsepower is withheld rather than guessed from the rate.
One stage
- Slurry
- 10,907.6 bbl
- Clean fluid
- 10,476.2 bbl
- Proppant

- Pump time
- 136.3 min
- Cycle time
- 181.3 min
- Rate per cluster
- 10.00 bpm

Limited entry target 500 psi — held at this rate and perf count.
The whole pad
- Stages
- 200
- Lateral treated
- 40,000 ft
- Pumping days

- Stages per day
- 6.62
- Water
- 2,095,238 bbl

Worth saying out loud
- Hydraulic horsepower is withheld: no treating pressure was entered, and it is not guessed from the rate.
Predict from your trained model
If your team has trained a model on your own results, export its model card from the platform and open it here. The pad above is then run through that model to predict the objective it was trained on — EUR, for example — instead of stopping at volumes and rate. The card is read in this browser; nothing is uploaded.
Take it with you
Every number here is closed-form planning arithmetic from what you typed — an estimate, not a simulated result, and it is labelled that way in both files.
One file with the inputs as typed, each result labelled solved or estimate, the residual, every refusal, and a fingerprint. Anyone can check it at /verify without an account.
Anyone can check that record at /verify without an account.
What this does not do
- It does not solve fracture growth, proppant placement or production — the full platform does that, and it says when it cannot converge.
- It does not pick perforations for you. Where the perf friction falls short of a limited-entry split, it says so and leaves the design to you.
- It does not quietly fix your input. A fractional stage count or a zero rate is refused by name.
