A method and apparatus for drilling and completing a bore hole are disclosed. The method comprises positioning a work string in the well, with a bottom hole assembly attached. The bottom hole assembly can include a drill bit, a drilling motor, orientation instrumentation, and a completion assembly. A fluid is circulated to drive the drill bit to drill the well to a target formation. Then, the completion assembly is used to produce fluids from the formation. Gravel packing can also be performed with the bottom hole assembly.
La présente invention concerne un procédé et un dispositif de forage et de complétion des trous de forage. Le procédé consiste à positionner dans le puits une tige de travail à laquelle est fixée un ensemble de fond de puits. Cet ensemble de fond de puits peut comporter un trépan, un moteur de foreuse, des instruments d'orientation, et un ensemble de complétion. En l'occurrence, on fait circuler un fluide d'entraînement actionnant le trépan de façon à forer le puits jusqu'à une formation cible. Puis on utilise l'ensemble de complétion pour produire les fluides à partir de la formation. L'ensemble de fond de puits permet de réaliser le gravillonnage des crépines.
