Well Control Kill Sheet (Wait & Weight)
A Wait & Weight kill sheet on one page. Enter the well, the drill string and the slow circulating rate pressure ahead of time. Once the well is shut in and stable, add SIDPP, SICP and the pit gain. The sheet returns the kill mud weight, the initial and final circulating pressures, the strokes and time to the bit and for one full circulation, MAASP with the original and the kill mud, an estimate of the influx height and gradient, and the drill pipe pressure schedule as a table and a chart. Three checks flag a casing pressure at or above MAASP, a kill mud as heavy as the shoe's leak-off, and an influx tall enough to reach the casing.
BOP Accumulator Sizing
Sizes a BOP accumulator unit. Enter the bottle size, the precharge, the minimum and fully charged operating pressures, the bottles installed and a design factor, and list the fluid each BOP function takes. The sheet returns the usable fluid per bottle, the fluid required, the number of bottles that needs and the pressure left after operating every function once with the pumps off. Checks cover the bottle count, the remaining pressure and the precharge margin. A chart shows accumulator pressure against the fluid drawn, with the minimum operating pressure and the required volume marked.
