Claim Text:
1. A system for accessing hydrocarbons in a well bore comprising: a first subsystem including a shockwave generator for introducing fractures at one or more points on the sides of the well bore, the first subsystem having a first length and first width, wherein the first width is less than a diameter of the well bore, the first subsystem including: a second subsystem for expanding fractures introduced by the first subsystem using freeze-thaw fracturing and thereby releasing hydrocarbons, a second subsystem having a second length and second width, the second width is less than a diameter of the well bore, the second subsystem including: a pump for introducing at least one of a fluid or gas to the first or second subsystem and a pressure valve for mechanically and functionally connecting the first subsystem to the second subsystem; wherein when the at least one of a liquid or gas is simultaneously pumped into both the entrance port and the entrance annulus of the second subsystem, the pressure valve opens and allows the at least one of a liquid or gas to enter the first valved end of the first subsystem, thereby creating shockwaves as the at least one of a liquid or gas exits through the first plurality of exit slots; and further wherein when the at least one of a liquid or gas is pumped into the entrance port of the second subsystem, the at least one of a liquid or gas exits the second plurality of exit slots into the annulus and returns out of the second subsystem through the dual flow annulus.
