Abstract

See full text

A method for treating a well in a hydrocarbon-producing subterranean production zone. The method for treating well-producing hydrocarbons from a subterranean production zone includes dry mixing a granite waste powder (GWP) in a form of rock aggregates and a cement to form a mixture. Then the mixture is added to the cement composition containing water, pre-hydrated sodium bentonite, calcium chloride, a dispersant, and an alcohol-based defoamer to form a cement slurry. The cement slurry is prepared at a density of from 13.5 pounds per gallon (ppg) to 14.5 ppg and contains the GWP in a range of from 5 wt. % to 20 wt. % of the cement slurry. 10 wt. % to 15 wt. % perlite is added into the cement slurry to form a ternary blend which is cured and then the cured product is injected into the well to seal the well at the subterranean production zone.
