Abstract

Perforation and stimulation of a plurality of selected sections of a cased well is completed with a single insertion of a well tool. The process includes successive stages of perforating and stimulating selected sections of the well in sequence starting from a lowest section in the wellbore. In each stage, selected charges carried by a perforating gun of the well tool are detonated to perforate the casing and stimulation fluid is pumped through the perforating gun to an injection nozzle connected to a bottom end of the perforating gun. The method and apparatus in accordance with the invention enable perforation and stimulation of selected sections of cased wells more quickly and at lower cost.
