Observed volume is never inferred from the planned value. A variance label is a review cue only; it is not a kick/loss diagnosis or an operational instruction.

Condition

Declared model boundary: static cylindrical displacement and free-surface fall only. Surge/swab, compressibility, gas, ballooning, losses, influx, vessel/riser motion, sensor lag, transfers, and dynamic tank response are excluded.

STATIC_DISPLACEMENT_MODEL

Static cylindrical displacement only. Surge/swab, compressibility, ballooning, losses, influx, gas migration, riser motion, sensor lag, transfers, and dynamic trip-tank response are excluded.

Operational use warning: verify physical tally, connection dimensions, end condition, pump and tank calibration, line-up, sensor resolution, and transfers. Treat unexplained variance under the approved program; this worksheet does not diagnose influx or loss.
