Formula No.8 Mud Density with Trip Margin

This formula is used to calculate mud density with including safety margin or trip margin.
The formula is:

8.

MUD DENSITY WITH TRIP MARGIN INCLUDED (ppg)

[Safety Margin (psi) ÷TVD (ft) ÷ 0.052] + Mud Density (ppg)

or

\dfrac{Safety\;Margin\;(psi)}{TVD(ft) \times 0.052}+Mud\;Density\;(ppg)
