Method of Enhance the Production Capacity of an Oil Well

Abstract

A method to increase oil production from an oil well comprising a plurality of production zones is presented, wherein the method selects a production zone, isolates that selected production zone, and reconfigures flow lines to allow direct injection of materials under pressure into the selected production zone. The method determines a treatment pressure based upon soil porosity in the selected zone, injects a brine solution into the selected production zone at the selected pressure, and maintains the selected pressure in the selected production zone for at least 72 hours.

         10 . The method of  claim 9 , further comprising injecting at least 9,000 gallons of said bacteria system. 
     
     
         11 . A method to increase an oil cut percentage produced from an oil well comprising a plurality of production zones, comprising:
 selecting a production zone;   installing a down hole tool comprising a plurality of perforations into said oil well to isolate said selected production zone;   reconfiguring flow lines to allow direct injection of materials under pressure into said selected production zone;   determining a treatment pressure based upon soil porosity in said selected production zone;   injecting a brine solution into said selected production zone at said selected pressure;   maintaining said selected pressure in said selected production zone for at least 72 hours.   
     
     
         12 . The method of  claim 11 , wherein said determining further comprises calculating a kinematic porosity of soils disposed in said selected production zone. 
     
     
         13 . The method of  claim 12 , wherein said calculating further comprises:
 measuring a soil density of said soils disposed in said selected production zone;   determining a field capacity of said soils disposed in said selected production zone; and   setting said kinematic porosity equal to said soil density minus said field capacity.   
     
     
         14 . The method of  claim 11 , wherein said injecting further comprises injecting at least 20 cubic meters of said brine solution. 
     
     
         15 . The method of  claim 14 , wherein said injecting further comprises preparing a brine solution comprising at least 23,000 ppm sodium chloride. 
     
     
         16 . The method of  claim 11 , further comprising injecting into said selected production zone at said selected pressure at least 550 gallons of a solvent system comprising a mixture of petroleum distillates, wherein said solvent system is injected into said selected production zone prior to injection of said brine solution. 
     
     
         17 . The method of  claim 16 , further comprising injecting into said selected production zone at said selected pressure a mixture of humic acid and fulvic acid in phosphoric acid after injecting said solvent system but prior to injecting said brine solution.
