Yield Point (YP,) is resistance of initial flow of fluid or the stress required in order to move the fluid. You can simply say that 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. Moreover, frictional pressure loss is directly related to the YP. If you have higher YP, you will ...

Although seldom used today, clays were classified as high-, medium- or low-yield bentonites. A "good" bentonite produced at least 85 bbl of mud per ton. High-yield clays produced 30 to 50 bbl/tonUS, and low-yield clays produced 15 to 30 bbl/tonUS. (Note that yield and yield point are not related terms.)
