Abstract
A method to incorporate calcined Saudi calcium bentonite as a low-density cement admixture in oil and gas well applications. Low-density cement systems were designed using the calcined Saudi calcium bentonite in an amount of from 10 to 30 weight % of the admixture to form a low-density cement slurry at a density of from 10 pounds per gallon (ppg) to 15 ppg; and injecting the low-density cement slurry into the well to seal the well from the geological formation; and curing the low-density cement slurry in the well to seal the well from the geological formation.
