Patent

CA 2194417

A method is disclosed which allows running liners with external casing packers on coiled tubing in a single trip. The compact design afforded by being able to support the liner near its lower end adjacent the lowermost external casing packer allows for a combined overall length of running tool and inflation tool short enough to fit into a standard lubricator.

'invention est une méthode permettant de descendre en une seule passe des trains avec garniture étanche extérieure sur tube spiralé. L'ensemble compact résultant de la possibilité de supporter le train près de son extrémité inférieure à côté de la garniture extérieure la plus basse autorise l'utilisation d'un ensemble outil de descente et outil d'inflation suffisamment courts pourqu'il puisse s'adapter à un graisseur standard.
