SYSTEM AND METHOD TO INITIATE PERMEABILITY IN BORE HOLES WITHOUT PERFORATING TOOLS

摘要

A shockwave generator pre-treats one or more production zones within a well to facilitate recovery of liquid and gaseous hydrocarbons from the well. The well may be heated to a particular temperature, where after a cooling agent is introduced through the shockwave generator which effects a cooling action in the walls of the well and induces cracking which is propagated by the tremors or shocks of the cooling agent as it exits the generator. The initiated cracks may be further propagated using one or more additional stimulation methods, including a freeze-thaw method which is implemented through a subsystem having overlapping components with the shockwave generator subsystem.

1. A system for introducing fractures into one or more points on the sides of a well bore comprising:
a component having a length and width, wherein the width at its longest is less than a diameter of the well bore, the component including:
a first open end;a hollow core for receiving at least one of a liquid or gas therein via the first open end;a second closed end; anda plurality of exit ports located along a periphery between the first open end and the second closed end of the component for facilitating exit of the at least one liquid or gas from the component into the well bore, wherein shockwaves are generated upon exit of the at least one liquid or gas from the component to cause fractures at one or more points on the sides of the well bore.
