Title (EN) METHOD OF PLUGGING AND PRESSURE TESTING A WELL
(FR) PROCÉDÉ DE BOUCHAGE ET DE TEST DE PRESSION D'UN PUITS
Abstract:
(EN) A method of plugging a well extending into a formation to facilitate temporary or permanent abandonment of the well. The method comprises conveying a plug placement and verification tool (PPVT) through the well, to a plug formation location, the PPVT comprising a stinger for delivering a plugging material into the well, an expandable packer disposed at one end of the stinger and a pressure sensor disposed below the expandable packer, and operating the expandable packer to form a seal in the well above the pressure sensor. The method further comprises delivering a plugging material from the stinger into a region of the well above the expandable packer, thereby forming a plug in the well, and thereafter creating a pressure change above the plug and verifying the integrity of the plug using the pressure sensor.
(FR) L'invention concerne un procédé de bouchage d'un puits s'étendant dans une formation, permettant de faciliter l'abandon temporaire ou permanent du puits. Le procédé consiste à transporter un outil de placement et de vérification de bouchon (PPVT) à travers le puits, vers un emplacement de formation de bouchon, le PPVT comprenant une élinde destinée à placer un matériau de bouchage dans le puits, un packer dilatable disposé à une extrémité de l'élinde et un capteur de pression disposé au-dessous du packer dilatable, et à faire fonctionner le packer dilatable pour former un joint d'étanchéité dans le puits au-dessus du capteur de pression. Le procédé consiste en outre à placer un matériau de bouchage provenant de l'élinde dans une région du puits au-dessus du packer dilatable, afin de former un bouchon dans le puits, puis de créer un changement de pression au-dessus du bouchon et de vérifier l'intégrité du bouchon à l'aide du capteur de pression.
