Title (EN) IMPROVEMENTS IN PARTICULAR RELATING TO SUBSEA WELL CONSTRUCTION
(FR) PERFECTIONNEMENTS APPORTÉS EN PARTICULIER À LA CONSTRUCTION DE PUITS SOUS-MARINS
Abstract:
(EN) In an embodiment there is described a method of constructing a subsea well. There is also described an associated unit. The method may comprise the steps of: providing a unit comprising at least one component of a flow control assembly, the flow control assembly to be operable for controlling a flow of injection or production fluid during operation of the well after the well has been constructed; lowering the unit through sea toward a seabed; receiving part of the unit in a subsurface of the seabed to anchor the unit in place, part of the unit projecting above the seabed, whereby said component of the flow control assembly is positioned in the projecting part; and performing at least one well construction operation through a bore in the unit.
(FR) Selon un mode de réalisation, l'invention concerne un procédé de construction d'un puits sous-marin. L'invention concerne également une unité associée. Le procédé peut comprendre les étapes suivantes consistant : à fournir une unité comprenant au moins un élément d'un ensemble de régulation de débit, l'ensemble de régulation de débit pouvant permettre de réguler un débit de fluide d'injection ou de production pendant le fonctionnement du puits après que le puits a été construit ; à abaisser l'unité à travers la mer vers un fond marin ; à recevoir une partie de l'unité dans une sous-surface du fond marin pour ancrer l'unité en place, une partie de l'unité faisant saillie au-dessus du fond marin, ledit élément de l'ensemble de régulation de débit étant positionné dans la partie saillante ; et à réaliser au moins une opération de construction de puits à travers un alésage dans l'unité.
