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)

$$ W_{\max }=\frac{P_{l o}}{0.052 * H}+W_{u} $$
