Title (EN) KICKOFF PLUGS AND METHODS OF DIRECTIONAL DRILLING AND FORMING KICKOFF PLUGS
(FR) BOUCHONS DE DEMARRAGE ET PROCEDES DE FORAGE DIRECTIONNEL ET DE FORMATION DE BOUCHONS DE DEMARRAGE
Abstract: front page image
(EN)Degradable kickoff plugs are provided, which may comprise a degradable material and an acid-base cement. Methods of drilling a well bore in a subterranean formation comprising placing a self-degrading kickoff plug or the like in the well bore are provided. An example of a method comprises: providing a self-degrading cement composition that comprises a degradable material, an acid source, a base source, and a water source; placing the self-degrading cement composition in a desired location in a well bore that penetrates a subterranean formation; and allowing the self-degrading cement composition to set to form a hardened kickoff plug.
(FR)L'invention concerne des bouchons de démarrage dégradables comprenant un matériau dégradable et un ciment acide-base. L'invention concerne également des procédés de forage d'un puit dans une formation souterraine, lesdits procédés comprenant la mise en place dans le puit d'un bouchon de démarrage autodégradable ou analogue. Un exemple de ce procédé comprend les étapes suivantes : se procurer une composition de ciment autodégradable comprenant un matériau dégradable, une source d'acide, une source de base, et une source d'eau ; placer la composition de ciment autodégradable à un emplacement désiré dans un puit réalisé dans une formation souterraine ; laisser prendre la composition de ciment autodégradable de manière à former un bouchon de démarrage durci.
