Title
(EN) DOWNHOLE INTERVENTION
(FR) INTERVENTION EN FOND DE TROU
Abstract
(EN)
The present invention is directed to novel methods and apparatus for the design, installation, use, recovery, and reuse of a Self Supporting Riser (SSR) for wells that are not under a platform. The SSR of the present invention uses standardized joints that can be recovered, potentially warehoused, and recombined in different configurations for different purposes or locations. Emphasis is on methods and apparatus that use relatively small vessels subject to high motions in the use and recovery of the SSR, especially the methods, apparatus and vessel for downhole intervention and work over through a SSR.
(FR)
L'invention concerne de nouveaux procédés et un nouvel appareil qui permettent de concevoir, installer, utiliser, récupérer et réutiliser un tube prolongateur autoporteur destiné à des puits qui ne se trouvent pas sous une plate-forme. Le tube prolongateur autoporteur selon l'invention fait appel à des joints normalisés qui peuvent être récupérés, éventuellement entreposés, et recombinés selon différentes configurations destinées à différents objectifs ou différents emplacements. L'invention se rapporte en particulier à des procédés et un appareil qui font appel à des navires relativement petits soumis à des mouvements importants pour exploiter et récupérer le tube prolongateur autoporteur, en particulier à des procédés, un appareil et un navire qui permettent de mener à bien une intervention et un travail en fond de trou par le biais du tube prolongateur autoporteur.
