Title (EN) METHOD AND SYSTEM FOR HYDRAULIC FRACTURING
(FR) PROCÉDÉ ET SYSTÈME DE FRACTURATION HYDRAULIQUE
Abstract: front page image
(EN)A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by extendable members that are located behind isolation valves. The extendable members can comprise a biodegradable plug that allows extension of the extendable members by application of pressure. With the plug remained in place, additional pressure can be delivered until at least a portion of the degradable material is pushed onto the surface of the formation. At least a portion of the pushed degradable material provides a seal between the end of the extendable members and the surface of the formation to allow pressure to build until the formation frac gradient is exceeded and the formation is fraced.
(FR)Cette invention concerne une opération de fracturation réalisée dans un puits non tubé sans isolation de l'espace annulaire. Des éléments extensibles disposés derrière des vannes d'isolement sont étendus dans l'espace annulaire. Lesdits éléments extensibles peuvent comprendre un bouchon biodégradable qui permet l'extension des éléments extensibles par application d'une pression. Quand le bouchon reste en place, une pression supplémentaire peut être fournie jusqu'à ce qu'au moins une partie du matériau biodégradable soit poussée à la surface de la formation. Au moins une partie du matériau biodégradable ainsi poussé forme un joint entre l'extrémité des éléments extensibles et la surface de la formation de façon à permettre l'accumulation de la pression jusqu'au dépassement du gradient de fracturation permettant la fracturation de la formation.
