Subsea considerations - Maximum allowable mud weight - Subsea stack from leakoff test
Input(s)
\(P_{l o}\): Leak off test pressure (psi)
\(\mathrm{H}\): TVD Rotary Bushing to Casing Shoe (ft)
\(W_{u}\): Mud weight in use (ppg)
Output(s)
\(W_{\max }\): Maximum Allowable Mud Weight (ppg)
Formula(s)
\[
W_{\max }=\frac{P_{l o}}{0.052 * H}+W_{u}
\]
