Wellbore Genius
Lab curve bench
Type the readings off the bench sheet and the rates off the contract. The regressed curve becomes the well's forecast rheology and pump-rate seed; the rate cards price the forecast's rig days.
This well has no published curve — the forecast is on the template mud.
Bench readings
Dial deflection at each rotor speed, exactly as written on the sheet. Leave a speed blank when it was not run — the regression uses only what you typed.

0 readings typed — the regression needs at least 3.
Rate cards
No rigs on the roster — add one so the forecast can price its days. These are the roster rates /drilling-forecast prices its rig days on — anything left on the seed is flagged as a guess.

Rig-day spend on these contracts
No rig on this well's calendar — assign one so the contracts have days to price. Days come from this well's calendar; the dollars are the rate cards above, so this is exactly what /drilling-forecast now charges.

What /drilling-forecast will use
Forecast ECD is still on the template mud — publish a curve to replace it. 8 forecast inputs are still template values.
| Input | Value | Source | Why |
|---|---|---|---|
| Hole ID | 8.50 in | Template default | No conduit in the tally — 8.5 in template hole |
| Pipe OD | 5.00 in | Template default | No string in the tally — 60 % of hole ID assumed |
| Mud weight | 12.00 ppg | Template default | Well header has no fluid density |
| TVD | deepest shoe | Tubular tally | No header TVD — hydrostatic uses the deepest shoe |
| Forecast rheology | PV 18 / YP 12 | Template default | No Fann curve published for this well — assumed PV/YP mud |
| Pump-rate seed | 204 gpm | Template default | 106 ft/min in the 8.50×5.00 in annulus (floor 90 ft/min); the optimiser re-solves per stage |
