Abstract
A well completion method is claimed for steam stimulation of a wellbore, either horizontal or vertical, where limited entry perforations are utilized. Limited-entry perforations of specified spacing and size are placed into a closed-end injection tubing. Steam is directed down the tubing and distributed through the perforations which act as steam chokes, under critical flow conditions, thereby causing uniform steam injection and uniform heating along a desired length of a horizontal wellbore.
