Basic Drilling Fluids

When we pump this bentonite fluid into the hole under pressure, the fluid, just like water, wants to flow through the sand or gravel 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...
