Abstract
A technique of forming perforations in a wellbore. The formation of perforations is carefully controlled by a perforating device to create a series of sequential perforations in a desired arrangement. The perforating device is lowered to a desired location in the wellbore and then moved incrementally to enable sequential perforations in the desired arrangement.
