Methods of additional (optional) stimulation is much more than basic (initial) opening methods. Their value and real effectiveness of the various possible respectively much lower, and duration of a possible real effect can be up to several months. Most common method of stimulation is a chemical treatment.

KNOWN TODAY METHODS OF STIMULATION

KNOWN TODAY METHODS OF STIMULATION

Efficacy and duration of any known stimulation methods is depending on size of opened surface area in casing and cement. None of the currently known stimulation methods cannot overcome this barrier to fully effect the productive formation behind the casing.

EXAMPLE OF USE STIMULATION AFTER SLOT PERFORATION TECHNOLOGY

Maxxwell Production - hydro-slotting perforation technology

Attempts to additional stimulation of oil or gas wells through the inches-holes in the casing after gun or cumulative perforations can be compared with the works through the keyhole.
