Kill Weight Mud
How do you control a kick when drilling a well? In today’s video blog we learn what kill weight mud is, why it is useful, and how to calculate it. Be sure to watch the video above and subscribe to our youtube channel, but if you’re pressed for time, feel free to utilize the quick summary below.
A kill weight mud is a mud with a density high enough to produce a hydrostatic pressure at the point of influx, or where the kick is entering the wellbore, that will be sufficient enough to shut in the well and thus killing the well. Your kill weight mud (KWM) is the mud weight that will allow you to keep control of your well during times where a kick may be occurring.
Here is the equation to calculate your kill weight mud:
- KWM = Mud weight (ppg) + (Shut-in drill pipe pressure (psi) / 0.052 / Well TVD (ft))
- KWM = MW + (SIDPP/0.052/TVD)
This equation is very important and useful for anyone working near drilling operations!
