Drilling Deeper with Bentonite

It is useful in drilling wells because water mixed with bentonite tends to coat the walls of the hole and keep it from collapsing Drillers call this coating a filter cake When you are using only water as a drilling fluid and you are drilling in sand the walls of the hole will start collapsing as soon as you turn off the water

Field Applications of PHPA Muds Drilling Fluid Management Disposal

Pre hydrated bentonite is used as a supplemental viscosifier in freshwater formulations but should be used sparingly in saline environments because of difficulties in controlling rheology According to Chesser 13 this is especially true in KCI/PHPA muds because the flocculation of bentonite by the potassium ion can adversely affect rheological
