<p>The invention relates to a method and equipment for perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore, which are used for the stimulation of multiple formation intervals without the necessity of removing the equipment from the wellbore between steps, meant to increase the production of oil and gas. According to the invention, the method for perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore consists in :deploying a bottom hole assembly (BHA), using a deployment means within the above mentioned wellbore, said bottomhole assembly (BHA) being provided with a perforating device and a sealing mechanism, followed by positioning said bottomhole assembly within said wellbore so that the low end of the assembly is below the lowest target zone, perforating then the previously established interval and displacing the above mentioned sealing mechanism, so as to establish a hydraulic seal of the target zone in said wellbore. Finally, a treatment fluid is pumped into the wellbore in the perforations created by said perforating device, without removing the equipment from the wellbore. According to the invention, the perforating and treating equipment used for applying said method is provided with a bottomhole assembly (27, BHA) having at least one perforating device (134, 144 and 154) for successively perforating multiple intervals and at least one sealing mechanism (120), capable of establishing a hydraulic sealing so that the treatment intervals should be treated separately.</p> |
