The quality of bentonite directly affects the safety and economic benefits of oil well drilling engineering. Due to the fact that most of the qualified drilling-grade bentonite used in water-based drilling fluid under current API standards are modified by physico-chemical methods, its performance maybe extremely unstable in high temperature conditions, which implies that …

Measure out the desired quantity (say, 2 grams). Pour 3/4 cup of boiling water into a small bowl (for 4 grams of bentonite, use 1-1/2 cups of boiling water) and add the bentonite. If you do not have a gram scale, one measured teaspoon of bentonite weighs 5.4 grams. Use a small whisk and mix the bentonite-water into a slurry.
