Yield Point and gel strength Mud Properties
Yield Point and gel strength Mud Properties

the Yield Point (YP) is, the attractive force among colloidal particles in, Drilling mud. The YP indicates the ability of the drilling mud to carry cuttings to surface at dynamic condition Moreover, frictional pressure loss is directly related to the YP. .

What is Yield Point (YP)? - Definition from Trenchlesspedia

Yield point gives an indication of the ability of the, drilling mud to lift, or remove the cu,ttings out of, the annulus. A drilling fluid with higher yield point will carry cuttings better than that with lower yield point.

YP is used to evaluate the ability of a ,mud, to lift cuttings out of the annulus. A high YP implies a non-Newtonian fluid, one that carries cuttings better than a fluid of similar density but lower YP. YP is lowered by adding deflocculant to a clay-based ,mud, and increased by adding freshly dispersed clay or a flocculant, such as lime.

Most drilling fluids currently used in the field, including water-based mud (WBM), synthetic-based mud (SBM) and oil-based mud (OBM), have a, non-zero, yield point (YP). A non,-zero, YP causes a sudden pressure change when the fluid starts to move or when it’s about to stop moving.
