Drilling Deeper with Bentonite – drillyourownwell

Bentonite is a clay that has an unusual and particularly useful characteristic. It can absorb many times its weight in water. 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.”

Bentonite in Drilling Mud - Advanced Science News

24/04/2015  The most common use of bentonite is in drilling fluids. The bentonite in the flush fluid lubricates and cools the cutting tools while protecting against corrosion. As the drilling fluid generates hydrostatic pressure in the borehole, it hinders fluid and gas penetration. The drilling liquid conveys the drill cuttings to the surface.

But in well drilling, the term ''drilling mud'' means a carefully engineered drilling fluid. Do not think that any old dirt will do the job. Bentonite properties include the ability to expand to ten times its volume when completely hydrated. It creates a very viscous, slippery, almost gel-like slurry that acts as a lubricant. The viscosity (runniness) of the slurry can be manipulated by adding ...

Four Steps to Mixing Good Drilling Fluid – Water Well Journal

18/01/2018  Typically, it will be an extended bentonite that increases the viscosity of the drilling fluid. This gives you gel strength, improves the carrying capacity of the fluid, and reduces fluid loss. You add the bentonite before any other polymers or additives because these inhibit the swelling of the clay.

Bentonite. Bentonite drilling muds are difficult to disperse and remove from a well bore because the Bentonite clay materials are relatively sticky and tend to cling to the well bore and casing. For this reason, most horizontal environmental wells are not drilled with bentonite; in fact, most specifications prohibit its use. During the drilling process, the driller's objective is to

Five tips for sealing a water well - GeoDrillingInternational

A cement mixture with no sand (also known as neat cement) or bentonite is ideal for creating a seal. Mixed with water, this forms a thin grout or slurry that will be pumped or poured down between the casing and the borehole wall. Drillers can use different combinations of cement and bentonite (equal parts, five per cent, no mixture at all).
