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)

$$ M S P=0.2 *\left(P * V * \frac{K W M}{C}\right)^{0.5} $$
