The possible use of local bentonite as an oil well cement additive

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,...
