Maximum Allowable Mud Weight Formula
\( MW_m \;=\; \dfrac{ p_l }{ 0.052 \cdot TVD } \cdot MW \) (Maximum Allowable Mud Weight) \( p_l \;=\; \dfrac{ MW_m \cdot 0.052 \cdot TVD }{ MW }\) \( TVD \;=\; \dfrac{ p_l \cdot MW }{ MW_m \cdot 0.052 }\) \( MW \;=\; \dfrac{ MW_m \cdot 0.052 \cdot TVD }{ p_l }\)
Symbol	English	Metric
\( MW_m \) = Maximum Allowable Mud Weight (ppg)	\(lbm \;/\; gal\)	-
\( p_l \) = Leak-off Pressure (psi)	\(lbf \;/\; in^2\)	-
\( TVD \) = True Vertical Depth of Casing Shoe	\(ft\)	-
\( MW \) = Mud Weight (ppg)	\(lbm \;/\; gal\)	-
