Title (EN) STRESS TESTING WITH INFLATABLE PACKER ASSEMBLY
(FR) ESSAI DE CONTRAINTE AVEC ENSEMBLE GARNITURE GONFLABLE
Abstract:
(EN) An inflatable packer assembly comprising a first fixed sleeve fixed to a mandrel, a first sliding sleeve moveable along the mandrel, and a first inflatable member connected to the first fixed sleeve and the first sliding sleeve. A second sliding sleeve is moveable along the mandrel, and a second inflatable member is connected to the first sliding sleeve and the second sliding sleeve. A second fixed sleeve is fixed to the mandrel and slidably engages the second sliding sleeve. An inflation flowline disposed within the mandrel is in fluid communication with interiors of the first and second inflatable members for inflating the first and second inflatable members to isolate a portion of a wellbore penetrating a subterranean formation. An injection flowline is disposed within the mandrel for injecting a fluid into the isolated wellbore portion at a high enough pressure to create microfractures in the subterranean formation.
(FR) L'invention concerne un ensemble garniture gonflable comprenant un premier manchon fixe fixé à un mandrin, un premier manchon coulissant mobile le long du mandrin, et un premier élément gonflable relié au premier manchon fixe et au premier manchon coulissant. Un second manchon coulissant est mobile le long du mandrin, et un second élément gonflable est relié au premier manchon coulissant et au second manchon coulissant. Un second manchon fixe est fixé au mandrin et vient en prise en coulissement avec le second manchon coulissant. Une conduite d'écoulement de gonflage disposée à l'intérieur du mandrin est en communication fluidique avec les intérieurs des premier et second éléments gonflables pour gonfler les premier et second éléments gonflables afin d'isoler une partie d'un puits de forage pénétrant dans une formation souterraine. Une conduite d'écoulement d'injection est disposée à l'intérieur du mandrin pour injecter un fluide dans la partie de puits de forage isolée à une pression suffisamment élevée pour créer des microfractures dans la formation souterraine.
