Fluid diversion through selective fracture extension

摘要: A system and method that uses fluid diversion to selectively re-fracture a location of multizone horizontal wellbore. tubing string is extended from the surface within wellbore be re-fractured. The annulus between contains first second contained string. may sealed off at or near pumped out initiate location. seal then unset down simultaneous pumping third After re-fracturing location, hydraulically isolated permit
