Title (EN) HYDRAULIC FRACTURING WITH STRONG, LIGHTWEIGHT, LOW PROFILE DIVERTERS
(FR) FRACTURATION HYDRAULIQUE AVEC DES DÉFLECTEURS RÉSISTANTS, LÉGERS ET PEU ENCOMBRANTS
Abstract:
(EN) Low profile diverters for, and the use of such diverters in, fracing operations to stimulate production of oil and gas are capable of seating against and temporarily sealing perforations, even when frac fluid is being pumped at high rates and pressures, or in horizontal or highly deviated well bores, where conventional ball sealers cannot be reliably used because of high flow rates and pressures.
(FR) La présente invention concerne des déflecteurs peu encombrants et leur utilisation dans des opérations de fracturation pour stimuler la production de pétrole et de gaz. Les déflecteurs sont capables d'être placés contre des perforations et de les étanchéifier temporairement, même quand un fluide de fracturation est pompé à des débits et pressions élevés, ou dans des puits de forage horizontaux ou fortement déviés, où des billes d'obturation classiques ne peuvent pas être utilisées de façon fiable à cause de débits et pressions élevés.
