The flow behaviour ,of drilling, fluids is complicated by the variation of ,apparent viscosity, with rate of shear or flow. Consequently, the Newtonian fluid equations are altered for application to typical ,drilling mud, systems. Swab and surge pressures can be computed using a calculation steps based on basic ,mud, flow Equations 1 to 10.

PV | Oilfield Glossary
PV | Oilfield Glossary

A low PV indicates that the mud is capable of drilling rapidly because of the low viscosity of mud exiting at the bit. High PV is caused by a viscous base fluid and by excess colloidal solids. To lower PV, a reduction in solids content can be achieved by dilution of the mud. Alternate Form: plastic viscosity. See: apparent viscosity
