2.5.4. Overbalance Mud Weight

Task is intended to be used in calculation of mud weight required to avoid influx of formation fluids into the hole.

Input Values
	Mud Weight	Density of the mud inside well
	TVD	True vertical depth of interest
	Overbalance Pressure	Excess pressure (additional for hydrostatic pressure of mud) to prevent influx of formation fluids into the wellbore
Results
	Overbalance Mud Weight	Density of the mud required to avoid influx of formation fluids into the wellbore
