Patent

CA 2562084

A completion involving expandable tools and/or tubulars involves running the assembly downhole in a single trip. The expansion can take place using a swage or inflatable or other expansion techniques. The assembly can be delivered on production tubing so that upon conclusion of the expansion and the setting of any hangers and barriers production or injection can proceed from a pre- selected zone or zones.

La présente invention concerne une complétion impliquant des outils déployables et/ou des éléments tubulaires qui consiste à faire courir cet ensemble au fond du puits en une seule passe. L'expansion peut se dérouler via l'utilisation de redresse-tube, via des techniques de gonflage ou via d'autres techniques d'expansion. Cet ensemble peut-être délivré sur des tiges de production de sorte que lors de la conclusion de l'expansion et de la fixation des supports et des barrières, la production ou l'injection puisse être effectuée à partir d'une zone ou de zones présélectionnées.
