An apparatus for reverse circulation cementing of surface casing in subterranean formations and associated methods are provided. One example of a method may involve a method of reverse circulation cementing a surface casing in a well bore with a conductor casing positioned therein comprising: providing a tool comprising at least one isolation device coupled to the surface casing; positioning the isolation device in the well bore to isolate an annulus between the surface casing and the conductor casing; flowing cement through a port in the conductor casing in a reverse circulation direction; and allowing the cement to set therein.
La présente invention concerne un appareil de cimentation à circulation inverse de tubage de surface dans des formations souterraines ainsi que des méthodes connexes. Un exemple de méthode peut faire appel à une méthode de cimentation à circulation inverse d'un tubage de surface dans un puits de forage, un tubage conducteur étant positionné dans ce dernier, comprenant : la fourniture d'un outil ayant au moins un dispositif d'isolation couplé au tubage de surface; le positionnement du dispositif d'isolation dans le puits de forage pour isoler un annulaire entre le tubage de surface et le tubage conducteur; l'écoulement de ciment dans le tubage conducteur par circulation inverse; permettre le durcissement du ciment.
