Method of gas, oil, and mineral production using a clean process system and method

Abstract

The invention is a system and process for providing a clean, non-contaminating process, for producing fracturing of shale, limestone, sands and other geological and mining formations to release natural gas, oil and minerals within a formation. The system used in the process produces on site the energy required to induce fracturing, removing natural gas and oil, and to recycle fluids used in fracturing for additional use. Removable storage provides the necessary materials to provide fracturing, removal and processing of the fracturing liquids for addition use at one or more sites, and to provide processing, storage and transportation of the resulting natural gas and oil.

1 . A method of providing fracturing in a well bore, to produce at least one of natural gas and oil, having vertical and horizontal well bore regions,
 injecting liquid CO2 into the well bore;   Injecting pressurized steam into the carbonated water to cause fracturing of the walls of the well;   the proportion of liquid CO2 and steam being in the range of 60-80% liquid CO2 and 20-40% steam by volume.   
     
     
         2 . The method according to  claim 1 , wherein the well bore has vertical and horizontal portions and a pipe in the well extends into the vertical and horizontal portions of the well bore;
 Wherein, pressurized steam is injected into the horizontal region of the well bore through peripheral openings in the pipe in the horizontal region of the well bore; and   Injecting Fracking sand.   
     
     
         3 . The method according to  claim 1  wherein the liquid CO2 is refrigerated prior to injecting it into the well. 
     
     
         4 . The method according to  claim 1 , wherein at least one of natural gas and oil, carbonated water, and any released CO2 are removed from the well, the carbonated water and CO2 being separated from at least one of natural gas and oil, and processed for further use. 
     
     
         5 . (canceled) 
     
     
         6 . A method of providing fracturing in a well bore, to produce at least one of natural gas and oil;
 injecting refrigerated carbonated water into the well bore;   injecting pressurized steam into a region of the well bore through peripheral openings in a pipe extending downward into the well bore and into a horizontal region of the well bore.   
     
     
         7 . The method according to  claim 6 , wherein the peripheral openings in the pipe are spaced apart to maximize the insertion of the pressurized steam in equal portions along the length of the horizontal portion of the pipe, the openings being spaced apart in decreasing spaces between the openings. 
     
     
         8 . The method according to  claim 1  including the triggering of a sensor valve when a sufficient amount of liquid CO2 has been released into the well bore to close off the insertion of cooled CO2 liquid CO2 and opening a second valve to allow pressurized steam to be injected into the well to rapidly expand the liquid CO2. 
     
     
         9 . A system for producing fracturing in a well bore utilizing only refrigerated carbonated water, sand, and pressurized steam, comprising:
 a well bore having a vertical and horizontal regions;   a pipe extending downward in the vertical region and into the horizontal region;   a storage unit for holding refrigerated carbonated water for injection into the well;   a steam generator for injecting pressurized steam into the carbonated water for producing fracturing in the well; and   separator for removing at least one of gas and oil released during the fracturing process.   
     
     
         10 . The system according to  claim 9 , including an isolation plug to prevent the pressurized steam, contaminates and carbonated water from moving up the vertical portion of the well, and increasing the pressure in any portion of the well bore to produce greater fracturing in the well. 
     
     
         11 . The system according to  claim 9 , including a seal at the top of the well to prevent any gases and other materials from leaving the well and entering the atmosphere. 
     
     
         12 . (canceled) 
     
     
         13 . The system according to  claim 9 , where any materials removed from the well bore pass through a particulate filter to remove particulate material from fluids removed from the well. 
     
     
         14 . The system according to  claim 13 , wherein the system includes at least two particulate filters, only one filter being used at a time so that the one that is not being used can be cleaned for future use.
