Drilling Fluid Properties | Know Energy Solutions

Nov 01, 2012· A) DENSITY (SPECIFIC GRAVITY) Density is defined as weight per unit volume. It is expressed either in ppg (lbs gallons) or pound per cubic feet (lb/ft3) OR kg/M^3 or gm/cm^3 or compared to the weight of an equal volume of water as specific gravity. Density is measured with a mud balance.
