Title (EN) FLOATING OIL AND GAS FACILITY WITH A MOVABLE WELLBAY ASSEMBLY
(FR) INSTALLATION DE PÉTROLE ET DE GAZ FLOTTANTE DOTÉE D'UN ENSEMBLE DE BAIE DE PUITS MOBILE
Abstract:
(EN) A mobile offshore drilling unit is converted to provide drilling, completion and workover access to multiple dry tree wells from a drilling derrick to allow production and export of oil and gas from high pressure, high temperature reservoirs in deep offshore waters. Existing practice has been for the drilling derrick on a production platform supporting dry tree wells to be moved over a fixed well slot. The present invention provides a movable wellbay that supports multiple top-tensioned subsea well tieback risers, which may be positioned directly below the derrick's rotary table and/or beneath another operating device. The use of top-tensioned subsea well tieback risers supported by the movable wellbay allows the converted facility to drill, complete, maintain, improve and produce from subsea wells through dry trees.
(FR) L'invention concerne une unité de forage en mer mobile convertie pour fournir un forage, l'achèvement et le reconditionnement d'accès à de multiples puits d'arbres secs à partir d'un derrick de forage pour permettre la production et l'exportation de pétrole et de gaz à partir de réservoirs à haute pression et à haute température dans des eaux profondes en mer. La pratique existante a été pour le derrick de forage sur une plate-forme de production portant des puits d'arbre sec à déplacer sur une fente de puits fixe. La présente invention concerne une baie de puits mobile qui porte de multiples colonnes montantes de fond de puits sous-marines tendues par le haut, qui peuvent être positionnées directement sous la table rotative du derrick et/ou sous un autre dispositif d'actionnement. L'utilisation de colonnes montantes de fond de puits sous-marines tendues par le haut portées par la baie de puits mobile permet à l'installation convertie pour forer, de terminer, de maintenir, d'améliorer et de produire à partir de puits sous-marins par l'intermédiaire d'arbres secs.
