Drilling fluid Wikipedia

Liquid drilling fluid is often called drilling mud. The three main categories of drilling fluids are waterbased muds (which can be dispersed and nondispersed), nonaqueous muds, usually called oilbased mud, and gaseous drilling fluid, in which a wide range of gases can be used.

Composition and Properties of Drilling and Completion ...

Density, or mud weight, is determined by weighing a precise volume of mud and dividing the weight by the volume. The mud balance provides the most convenient way of obtaining a precise volume. The number obtained depends partly on the effective viscosity at the rate of shear prevailing in the orifice, and partly on the rate of gelation.
