Perforación

Hoja de control — método del perforador

Kill mud weight, initial and final circulating pressure and the step-down schedule, for rehearsal and for checking a sheet that has already been worked.

Cómo se calcula

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.

Dónde deja de ser cierto

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.

La capacidad que automatiza esto

DR-02Detección Temprana de Influjo y Control de PozoA kick is formation fluid entering the wellbore. Left unchecked it becomes a blowout. This watches eleven sensor streams and warns the crew minutes earlier than pit-volume alarms do.
