Equivalent circulating density
Input(s)
\(\rho_{\mathrm{m}}\): Mud Weight (ppg)
\(\delta \mathrm{P}_{\mathrm{a}}\): Annulus Pressure Loss (psi)
\(\mathrm{L}_{\mathrm{t}}\): True Vertical Depth \((\mathrm{ft})\)
Output(s)
ECD: Equivalent Circulating Density (ppg) (ppg)
Formula(s)
\[
\mathrm{ECD}=\rho_{\mathrm{m}}+\left(\frac{\delta \mathrm{P}_{\mathrm{a}}}{0.052 * \mathrm{~L}_{\mathrm{t}}}\right)
\]
