The graphical representation of the ,plastic viscosity,, ,yield point, and apparent ,viscosity,, as determined by substituting the dial-reading data into Equations (1), (2) and (3), is presented in Figure 1. The graph shows that the cassava starch additive affects the rheological properties of the ,drilling mud,…

Bingham plastic - Wikipedia
Bingham plastic - Wikipedia

A ,Bingham plastic, is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C. Bingham who proposed its mathematical form.. It is used as a common mathematical model of ,mud, flow in ,drilling, engineering, and in the handling of slurries.A common example is toothpaste, which will not be extruded until a certain ...

Flow of Drilling Mud | Transactions of the AIME | OnePetro

The behavior ,of drilling mud, does not conform in every detail with thedefinition of a ,plastic, solid as given, because ,mud, actually flows slightly atpressures below its ,yield point,. However, for practical purposes the definitiondescribes the condition adequately and has the advantage of simplicity.

Direct indicating viscometers also measure ,viscosity, but give us much more information. We can generate PV (,Plastic Viscosity,), AV (Apparent ,Viscosity,), YP (,Yield Point,) and gel strength properties for the ,drilling, fluid. With these numbers, we can get a good handle on the carrying capacity of the fluid at rest and when moving.
