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.
