Herschel-Bulkley yield-power law [YPL] model Figure 1 depicts typical rheological profiles for Newtonian, Bingham-plastic fluids, power law fluids, and Newtonian fluids. The Herschel-Bulkley yield-power law [YPL] model is the most accurate model for predicting the rheological behavior of common drilling fluids. Unfortunately, this does not often occur and the model usually over-predicts yield stresses shear stresses at zero shear rate by 40 to 90 percent. A quick and easy method to calculate more realistic yield stresses is to assume the 13 Halliburton All Rights Reserved Baroid Fluids Handbook Rheology fluid exhibits true plastic behavior in the low shear-rate range only. Some fluids viscosified with biopolymers can also be described by power-law behavior.

For our purposes, we can say that we only encounter two basic soil types: coarse and fine. In drilling sand and gravel, we need a fluid that will do two things.

First, we need a fluid that will stay in the hole. This is where bentonite comes in. Bentonite, when thoroughly mixed in water, breaks down into small particles called platelets.

These flat plate-like particles are small, very small. When you realize this, you can see why quality mixing equipment is so necessary. When we pump this bentonite fluid into the hole under pressure, the fluid, just like water, wants to flow through the sand or gravel.

Baroid Fluids Handbook - Welcome to the Baroid Fluids...

However, in this case the bentonite platelets in our fluid start to plaster or shingle off the wall of the borehole and form a filter cake that cuts off the flow of fluid into the surrounding sand or gravel. The water phase of the fluid that does filter through this filter cake is referred to as filtrate.

We can improve the filter cake quality and reduce the amount of filtrate going into the surrounding soil by one of two methods.

We can add more bentonite more available platelets or we can use certain polymers in conjunction with the bentonite to tighten the filter cake. This is not a polymer system. Move the pointer over the blue text and click it to see how a link work.
