Kick Tolerance

Kick Tolerance is the maximum volume of gas kick in barrels that we are able to successfully shut the well in and circulate the kick out of hole without breaking formation strength at shoe depth or overcoming the weakest anticipated facture pressure in wellbore.In order to calculate kick tolerance, we need to assume Kick Intensity (ppg), the depth that kick will happen, mostly is TD.

Let’s me explain more about kick intensity. The kick intensity is the difference between the formation pressure and current mud weight used in the wellbore. When you see the kick tolerance noted in the drilling programs from town, drilling engineers normally calculate kick intensity at TD.
