Abstract[English]
This invention discloses a well completion assembly and an associated method for enhanced hydraulic fracturing control in single or multiple production zones. The well completion assembly utilizes a dual-casing architecture comprising: (i) a primary load-bearing inner casing maintaining wellbore structural integrity, and (ii) a formation-engaged outer casing configured to optimize stress field modulation. Computational modeling demonstrates a reduction in formation breakdown pressure through controlled casing stiffness reduction.[French]
La présente invention divulgue un ensemble de complétion de puits et un procédé associé pour une maîtrise améliorée de la fracturation hydraulique dans des zones de production uniques ou multiples. L'ensemble de complétion de puits utilise une architecture à double tubage comprenant : (i) un tubage interne porteur de charge primaire maintenant l'intégrité structurale du puits de forage, et (ii) un tubage externe mis en prise avec la formation conçu pour optimiser une modulation de champ de contrainte. Une modélisation informatique démontre une réduction de la pression de rupture de formation par l'intermédiaire d'une réduction de rigidité de tubage maîtrisée.
