Viscosity is a measurement of a fluids resistance to flow: the greater the resistance, the higher the viscosity. As measured by the MARSH FUNNEL, the viscosity of the fluid in question is influenced by the density of the fluid (solids content) and gelation rate (beneficiated solids content). The viscosity of the drilling fluid in use should be based on a combination of the following parameters: drilling rate, pump and output capacity, mud density, cutting size, hole size, and solids removal equipment.
