Title (EN) METHOD OF WELL COMPLETION
(FR) PROCÉDÉ DE COMPLÉTION DE PUITS
Abstract:
(EN) A method for well completion employs a combined plugging and perforating operation for creating multiple spaced-apart clusters of perforations and optional stimulation treatments in stages. For each stage to be completed, a frac plug, carried, for example, along a wireline bottom hole assembly with perforating guns, is set in the wellbore distal (toward the toe end of the well) of the most proximal perforation cluster of the previous stage, thereby maintaining open hole conditions that provide adequate flow past the most distal perforation clusters in the current stage and minimizing proppant accumulation in the wellbore from stimulation operations. The method further allows subsequent pump down of tools and equipment even with the plug set in the wellbore.
(FR) La présente invention concerne un procédé de complétion de puits utilisant des opérations combinées de bouchage et de perforation afin de créer de multiples groupes de perforation espacés ainsi que d'éventuels traitements de stimulation par étages. Pour chaque étage devant être complété, on place par exemple un bouchon de fracturation porté sur un ensemble de câble de fond de trou doté de perforateurs dans le puits de forage (vers l'extrémité de pointe du puits), de façon distale par rapport au groupe de perforation le plus proximal de l'étage précédent, ce qui permet de maintenir des conditions de puits ouvert qui permettent un écoulement adéquat après les groupes de perforation les plus distaux dans l'étage actuel, tout en minimisant l'accumulation d'agent de soutènement dans le puits de forage du fait des opérations de stimulation. Le procédé permet en outre d'évacuer les fluides des outils et équipements ultérieurement, même lorsque le bouchon est installé dans le puits de forage.
