Equivalent density of a wellbore fluid

Input(s)

\(\mathrm{M}_{\mathrm{w}}\): Mud Weight (ppg)

TVD: True Vertical Depth \((\mathrm{ft})\)

APL: Annular Pressure Loss (psi)

Output(s)

ECD: Equivalent Circulating Density (ppg)

Formula(s)

\[ \mathrm{ECD}=\frac{\mathrm{APL}}{0.052 * \mathrm{TVD}}+\mathrm{M}_{\mathrm{w}} \]
