Title
(EN) METHODS OF CEMENTING A WELLBORE WITH THE USE OF AN OIL SWELLABLE ELASTOMER
(FR) PROCÉDÉS DE CIMENTATION D'UN PUITS DE FORAGE À L'AIDE D'UN ÉLASTOMÈRE POUVANT GONFLER DANS L'HUILE
Abstract
(EN)
A method of cementing a wellbore penetrating a subterranean formation comprises: injecting into the wellbore a cement spacer fluid comprising a carrier fluid, a quaternary surfactant, a viscosifier, and a proppant; injecting a cement slurry into the wellbore; and allowing the cement slurry to set.
(FR)
Un procédé de cimentation d'un puits de forage pénétrant dans une formation souterraine consiste: à injecter dans le puits de forage un fluide d'espacement de ciment comprenant un fluide porteur, un tensioactif quaternaire, un améliorant de viscosité et un agent de soutènement; à injecter une suspension de ciment dans le puits de forage; et à laisser durcir la suspension de ciment.
