Kill-Weight Fluid
Kill weight fluid, also called kill weight mud, is a drilling fluid with a density that generates sufficient hydrostatic pressure at the influx point within a wellbore. This fluid is a critical component of well control operations, for equalizing formation pressure and effectively stopping the flow of formation fluid into the wellbore.
The sequence of pumping the kill-weight mud into the well varies depending on the killing method employed. Kill weight is calculated based on stabilized shut-in drill pipe pressure (SIDP) recorded after encountering a kick.
