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