Title
(EN) TOOLS AND METHODS USEFUL WITH WELLBORE REVERSE CIRCULATION
(FR) OUTILS ET PROCÉDÉS UTILISABLES AVEC UNE CIRCULATION INVERSÉE DANS UN PUITS DE FORAGE
Abstract
(EN)
A method for reverse circulating a tool upwardly through a wellbore, the method including: providing a manipulator tool including an upper end and a lower end, conveying the manipulator tool down hole to a position adjacent a downhole tool, using the manipulator tool to manipulate the downhole tool, and reversing fluid flow through the well to create a pressure differential about at least one of the manipulator tool and the downhole tool such that the at least one of the manipulator tool and the downhole tool is lifted upwardly through the wellbore. A manipulator tool for use in a reverse circulating method is also described as are a tool catcher, a tool catching assembly and a tool catching method.
(FR)
L'invention concerne un procédé de circulation inversée d'un outil vers le haut à travers un puits de forage, le procédé comprenant les étapes consistant à : mettre en place un outil manipulateur présentant une extrémité supérieure et une extrémité inférieure, acheminer l'outil manipulateur vers le fond du trou jusqu'à une position voisine d'un outil de fond, utiliser l'outil manipulateur pour manipuler l'outil de fond et inverser l'écoulement du fluide à travers le puits pour créer un différentiel de pression autour de l'outil manipulateur et / ou de l'outil de fond de telle sorte que ledit outil manipulateur et / ou outil de fond soient soulevés vers le haut à travers le puits de forage. L'invention concerne également un outil manipulateur destiné à être utilisé dans un procédé de circulation inversée, ainsi qu'un dispositif de repêchage d'outils, un ensemble de repêchage d'outils et un procédé de repêchage d'outils.
