4 · Pipe data IDs and capacities used in the volumes
| Pipe or hole | Weight (ppf) | ID / hole size for volume (in) | bbl/ft | L/m |
|---|
Picking a weight fills in the standard (API) inside diameter. You can type your own ID. For open hole, type the caliper size (for example 13.08 for a 12¼" bit) to use it for volumes.

in open casing, pipe pulled
6 · Pump schedule
| Stage | Volume (bbl) | Rate (bpm) or time (min) | Time (min) | Cum. (h:mm) |
|---|
Thickening time is read from each slurry's Thickening time box (the first h:mm in it). The clock runs from batch-mixing until the cement is in place (for a plug, until the pipe is pulled clear).

How it works
- Tabs: each job on the well has its own tab with its own components, cement data and page, like the separate programs in the Drive folders. An empty tab copies the casings from the job before it.
- 20" casing: stab-in. Cement goes down the drill pipe into the shoe, and displacement is the drill-pipe volume to the stab-in point.
- 13⅜" and 9⅝" casing: top and bottom plugs. Displacement is the casing volume to the float collar.
- 7" liner: run on drill pipe. Cement covers the open hole, the liner lap and the set height above the liner top. Displacement is the drill-pipe volume to the liner top plus the liner volume to the landing collar.
- Squeeze: balanced plug. The spacer behind gives the same height as the spacer ahead. Displacement is the pipe volume above the spacer behind, minus any under-displacement.
- Formulas: bbl/ft = ID² ÷ 1029.4. Annulus = (outer ID² − inner OD²) ÷ 1029.4. Sacks = bbl × 5.6146 ÷ yield. Mix fluid = sacks × gps ÷ 42. Additives use the equivalent sacks after dead volume. Differential pressure = 0.052 × Σ(ppg × ft), annulus minus inside, with MD treated as TVD.
