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