Kick analysis - Maximum surface pressure from a gas kick in water-based mud
Input(s)
P: Formation Pressure (psi)
V: Pit Gain (bbl)
KWM: Kill weight mud (ppg)
C: Annular Capacity \((\mathrm{bbl} / \mathrm{ft})\)
Output(s)
MSP: Max surface pressure resulting from a gas kick in a water-based mud (psi)
Formula(s)
\[
M S P=0.2 *\left(P * V * \frac{K W M}{C}\right)^{0.5}
\]
