Abstract
Method of converting calcium bentonite to sodium bentonite that is suitable for use as drilling mud or a cement additive. After the addition of a calcium bentonite sample to a prepared soda ash solution at predetermined soda ash/bentonite weight ratios, the bentonite suspension is continuously heated and stirred for up to 24 h. The heating and stirring are crucial towards enhancing the sodium activation of the bentonite, as well as other rheological properties of the bentonite.
