发明名称 PROCESSES FOR HYDRAULIC FRACTURING
摘要 There is provided a process of stimulating a subterranean formation via a wellbore fluid passage of a cased wellbore. The process includes, with a perforating gun, perforating at least casing to form at least one or more perforations effecting fluid communication, via the wellbore fluid passage, between a first zone of the subterranean formation and a treatment fluid source. Treatment fluid is then injected via the wellbore fluid passage, from the treatment fluid source to the first zone such that fracturing of the first zone is effected. The injecting of the treatment fluid is then suspended. A perforating gun is then deployed within the wellbore fluid passage via wireline. The casing is then perforated to form at least one or more perforations effecting fluid communication, via the wellbore fluid passage, between a second zone of the subterranean formation and the treatment fluid source. While both of the first zone and the second zone are disposed in fluid communication, via the wellbore fluid passage, with the treatment fluid source, injecting treatment fluid from the treatment fluid source and into the wellbore fluid passage with effect that at least a fraction of the injected treatment fluid is directed to the second zone such that fracturing of the second zone is effected.
