Title (EN) METHODS AND APPARATUS FOR COMPLETING A WELL
(FR) PROCEDES ET APPAREIL PERMETTANT DE COMPLETER UN PUITS
Abstract: front page image
(EN)Methods and tools are described to reduce sanding including the steps of fracturing the cement sheath (13) in a localized zone around the casing (111) and having the fractured zone act as sand filter between the formation and openings (113) in the casing (111), with the openings being best pre-formed but temporarily blocked so as to allow a conventional primary cementing of the casing. The fracturing step can also be used for remedial operation to reopen blocked formation or screens.
(FR)L'invention concerne des procédés et des outils permettant de limiter l'ensablement. Lesdits procédés consistent à fracturer une gaine de ciment (13) dans une région localisée autour du tubage de revêtement (111) et comprenant la zone fracturée qui agit comme un filtre de sable entre la formation et les ouvertures (113) ménagées dans le tubage de revêtement (111), lesdites ouvertures étant préformées mais temporairement bloquées afin de permettre une cimentation primaire classique du tubage de revêtement. On peut également utiliser l'étape de fracturation pour une opération corrective afin de rouvrir une formation ou des filtres bloqués
