Abstract:
A method of cementing a wellbore penetrating a subterranean formation, the method comprising: injecting into the wellbore an oil-based fluid; injecting into the wellbore a cement spacer fluid comprising an aqueous carrier, an oil swellable elastomer, and a viscosifier; contacting the oil-based fluid with the cement spacer fluid to swell the oil swellable elastomer in the cement spacer fluid; injecting a cement slurry into the wellbore; and allowing the cement slurry to set.

Claim (Index 1):
A method of cementing a wellbore penetrating a subterranean formation, the method comprising:\n injecting into the wellbore an oil-based fluid; injecting into the wellbore a cement spacer fluid comprising an aqueous carrier, an oil swellable elastomer, and a viscosifier, the oil swellable elastomer particles comprising styrene ethylene butadiene styrene, and the viscosifier comprising diutan gum; contacting the oil-based fluid with the cement spacer fluid to swell the oil swellable elastomer in the cement spacer fluid; injecting a cement slurry into the wellbore; and allowing the cement slurry to set, wherein the cement spacer fluid comprises about 0.5 to about 24 pounds of the oil swellable elastomer per gallon of the cement spacer fluid; and the weight ratio of the oil-swellable elastomer to the viscosifier is about 95:5 to about 90:10.
