Bentonite Oil Well Cement

Bentonite was the first material extensively used as an oil well cement extender due to its ability to absorb large amounts of water. in oil well cementing, bentonite allows the use of increases amounts of mix water without water separation, which increased water content results in a lower density, greater, yield and reduces that fluid loss of cement slurry.
