Abstract | A method of hydrocarbon production at an offshore production facility (1). The method comprises: a) producing hydrocarbon fluid from a subsea wellhead (5) in communication with a subsea hydrocarbon reserve; b) conveying the produced hydrocarbon fluid to a topside structure (17) by means of the pressure of the produced hydrocarbon fluid at the wellhead; c) allowing the pressure of the produced hydrocarbon fluid at the wellhead to decline during step a) as a result of a declining hydrocarbon reserve pressure due to production of hydrocarbon fluid therefrom; and d) whilst allowing the pressure of the produced hydrocarbon fluid at the wellhead to decline, compensating for the declining pressure of the produced hydrocarbon fluid by introducing or increasing pumping of the produced hydrocarbon fluid using a subsea pump to ensure that the produced fluid is conveyed to the topside structure.
Procédé de production d'hydrocarbures au niveau d'une installation de production en mer (1). Le procédé comprend les étapes consistant à : a) produire un fluide hydrocarbure à partir d'une tête de puits sous-marine (5) en communication avec une réserve d'hydrocarbures sous-marine ; b) transporter le fluide hydrocarbure produit vers une structure supérieure (17) au moyen de la pression du fluide hydrocarbure produit au niveau de la tête de puits ; c) permettre à la pression du fluide hydrocarbure produit au niveau de la tête de puits de diminuer pendant l'étape a) à la suite d'une baisse de la pression de la réserve d'hydrocarbures en raison de la production d'un fluide hydrocarbure à partir de celle-ci ; et d) tout en permettant à la pression du fluide hydrocarbure produit au niveau de la tête de puits de diminuer, compenser la baisse de la pression du fluide hydrocarbure produit par l'introduction ou l'augmentation du pompage du fluide hydrocarbure produit à l'aide d'une pompe sous-marine afin de garantir le transport du fluide produit vers la structure supérieure. |
