Fremgangsmåte og innretning for fjernaktivering av komplettering i et borehull

A wellbore completion system utilizes casing conveyed devices (50) to establish a fluid communication path between a downhole formation (F) and the casing string (60). Extendible pistons (12) are mounted in the wall of the casing pipe string (60) and are extended toward contact with the downhole for...

description	A wellbore completion system utilizes casing conveyed devices (50) to establish a fluid communication path between a downhole formation (F) and the casing string (60). Extendible pistons (12) are mounted in the wall of the casing pipe string (60) and are extended toward contact with the downhole formation (F) after the casing (60) is set. Explosives (58, 72, 74) in the pistons are activated by a separately conveyed activation system (84, 89, 91, 93) which produces a pressure wave to detonate the explosives (58, 72, 74) and establish fluid communication between the casing (60) and formation (F).
