كيف تُحسب
- Kill mud weight = current MW + SIDPP/(0.052 × TVD).
- Initial circulating pressure = slow circulating rate pressure + SIDPP. Final = SCR × KMW/MW.
- The step-down schedule interpolates drill-pipe pressure linearly against strokes while kill mud fills the string.
- Influx gradient = mud gradient − (SICP − SIDPP)/influx height, with influx height from pit gain and annular capacity. Below 0.15 psi/ft the influx is read as gas.
المعايير التي تتحدثها
أين تتوقف عن الصحة
This is a rehearsal and review aid. It is not a well-control document and must not be used to kill a well. It assumes a vertical single-bubble influx, one uniform annulus, a constant pump efficiency and no migration while the sheet is being worked — none of which hold on a live well. The controlled kill sheet on the rig, filled in and signed by the people on tour, is the only sheet that counts.
