Worksheet sections

Declared scope

Single-stage primary casing, liner, or inner-string cementing. No multistage or reverse-circulation model.

Job basis

Declared calculation scope
Conventional single-stage primary casing; no multistage, reverse, squeeze, plug, transient hydraulics, or real-time control.
Interval order is target top of cement to shoe. Tail slurry is allocated from the shoe upward. Each interval may use geometric capacity or a measured/caliper override with its source note.
