Title (EN) COMPLETION ASSEMBLY FOR WELLBORES
(FR) ENSEMBLE DE CONDITIONNEMENT D'UN PUITS
Abstract:
(EN) The invention involves an assembly, specifically beneficial in deviated wellbores, which allows running into the wellbore with the complete completion assembly. The completion assembly includes one or more screens which may be pre-packed. Initially, a material which sets to form a permeable mass is deposited in the annular space outside the screens. After such material is deposited, cement or other sealing material is pumped into the annular space above the screens to complete the completion process. As a result, in one trip the deviated wellbore is completed with the permeable material deposited outside the screen or screens and cement being disposed in the annular space above the permeable material. Production can then begin.
(FR) Cette invention concerne un ensemble, particulièrement utile dans les forages déviés, qui permet le passage à l'intérieur du forage de l'ensemble de conditionnement dans sa totalité. Cet ensemble de conditionnement comporte un ou plusieurs filtres qui peuvent être pré-garnis. Initialement, on dépose une matière qui durcit pour former une masse perméable dans l'espace annulaire à l'extérieur des filtres. Après le dépôt de cette matière, on injecte par pompage du ciment ou un autre matériau d'étanchéité à l'intérieur de l'espace annulaire au-dessus des filtres, de manière à achever le processus de conditionnement. On parvient, par conséquent, à l'achèvement du forage dévié en une seule manoeuvre, la matière perméable étant déposée à l'extérieur du ou des filtres et le ciment étant disposé dans l'espace annulaire, au-dessus de la matière perméable. La production peut alors commencer.
