Title
(EN) METHOD OF ASSURING DISSOLUTION OF DEGRADABLE TOOLS
(FR) PROCÉDÉ PPOUR ASSURER LA DISSOLUTION D'OUTILS DÉGRADABLES
Abstract
(EN) The use of degradable components that include one or more chemical additives that are released upon the partial or full dissolution of the degradable component, and which can be used to facilitate in the dissolution of the degradable component. The degradable component can optionally include tracer elements that are released upon the partial or full dissolution of the degradable component, and which can be detected at the surface to ensure the desired degradation or removal of the degradable component as well as hydraulic access to that stage.
(FR) L'invention concerne l'utilisation de composants dégradables comprenant un ou plusieurs additifs chimiques qui sont libérés après dissolution partielle ou complète du composant dégradable, et qui sont utilisables pour faciliter la dissolution du composant dégradable. Le composant dégradable peut éventuellement comprendre des éléments traceurs qui sont libérés après dissolution partielle ou complète du composant dégradable, et qui peuvent être détectés à la surface pour assurer la dégradation ou l'élimination souhaitée du composant dégradable ainsi que l'accès hydraulique à cet étage.
