Patent

CA 2357719

A method is disclosed for creating one or more secondary sidetracks in an oil and/or gas well assembly which comprises a primary wellbore (2) and one or more primary sidetracks (6) so that a root-like multilateral well structure is created. The method makes use of an expandable well liner (9) in the primary sidetracks (6) so as to create a liner having a sufficient internal width to allow sidetracking equipment to be inserted and operated in the primary sidetrack to drill and complete the secondary sidetracks (7).

Cette invention concerne une méthode permettant de créer une ou plusieurs déviations dans un ensemble de puits de pétrole ou de gaz comprenant un puits (2) principal et un ou plusieurs puits (6) primaires de sorte que l'ensemble se présente sous la forme d'une structure multilatérale radiculaire. A cette fin, on utilise pour le puits (6) primaire une chemise (9) de puits extensible d'une largeur intérieure suffisante pour autoriser l'insertion et l'utilisation de matériel de forage en vue de la réalisation de déviations, ou puits (7) secondaires, à partir du puits principal.
