Mud weight Wikipedia

In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . In the field it is measured using a mud scale or mud balance.Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds. In conventional drilling fluids, barite is used to increase the density.

The following two drilling equations which is used by the mud engineer calculate pump output Q, at 100% volumetric efficiency. The constant, Ve, can be adjusted to calculate the bbl/stroke, gal/stroke, or liter/stroke.

Why would mud weight fall during a drilling operation? Quora

Answer (1 of 5): Mud weight would drop from: Liquid or gas inflow to wellbore. If the hydrostatic pressure from the drilling fluid is less than formation pressure in a permeable stone/formation then fluid will enter the wellbore. Wellbore fluid is either saltwater, freshwater, oil gas or combina...
