Abstract: A method for treating multiple intervals in a wellbore by perforating at least one interval (32, 33, or 34) then treating and isolating the perforated interval(s) (32, 33, or 34) without removing the perforating sleeve (101) from the wellbore during the treatment or isolation. The invention can be applied to hydraulic fracturing (222) with or without proppant materials as well as to chemical stimulation treatments.

Method and apparatus for wellbore fluid treatment
Jim Fehr,Daniel Jon Themig +1 more
- 19 Nov 2002
Abstract: A tubing string assembly is disclosed for fluid treatment of a wellbore. The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off. The tubing string can also be used where a ported tubing string is required to be run in in a pressure tight condition and later is needed to be in an open-port condition.
