Stripping/snubbing calculations-Maximum allowable surface pressure governed by formation

Input(s)

$W_{\max }$: Max allowable mud Weight (ppg)

$W_{u}$: Mud Weight in use (ppg)

$\mathrm{H}$: Casing Shoe TVD $(\mathrm{ft})$

Output(s)

MASP: Maximum Allowable Surface Pressure governed by Formation (psi)

Formula(s)

$$ M A S P=\left(W_{\max }-W_{u}\right) * 0.052 $$
