Title (EN) THROUGH CASING CORING
(FR) CAROTTAGE À TRAVERS UN TUBAGE
Abstract:
(EN) Devices and methods for obtaining core samples from a formation that surrounds a cased wellbore. A coring tool includes a casing cutter for cutting an opening in the casing and a coring device for obtaining a core sample from the formation.
(FR) L'invention concerne des dispositifs et des procédés permettant d'obtenir des carottes à partir d'une formation entourant un puits de forage tubé. Un outil de carottage comprend un dispositif de coupe de tubage permettant de pratiquer une ouverture dans le tubage et un dispositif de carottage permettant d'obtenir une carotte à partir de la formation.
