Abstract:
(EN) A system is provided to perform various wellbore operations, including retrieval and replacement of solid internal tree caps, for example. The system may include an open water lubricator having a piston assembly disposed therein. The system may also include a well control package connected to a distal end of the open water lubricator. The piston assembly is configured to extend through the well control package. Method using systems disclosed herein may be performed while maintaining at least two testable pressure barriers during each of the retrieving and replacement steps
(FR) La présente invention a trait à un système prévu pour effectuer diverses opérations de forage de puits, y compris la récupération et le remplacement de bouchons internes solides d'arbre, par exemple. Le système peut comprendre un lubrificateur à eau libre ayant un ensemble piston disposé à l'intérieur de celui-ci. Le système peut également comprendre un boîtier de commande de puits relié à une extrémité distale du lubrificateur à eau libre. L'ensemble piston est conçu pour s'étendre à travers le boîtier de commande de puits. Le procédé utilisant des systèmes décrits dans la présente invention peut être réalisé tout en maintenant au moins deux barrières de pression pouvant être testées pendant chacune des étapes d'extraction et de remplacement.
