System and method for fracking of shale rock formation

Abstract

The various embodiments of the present invention provide a system for fracking a plurality of shale rocks in a shale reservoir. The system comprises a shock tube for generating a plurality of shock waves a support system for holding the shock tube, a guide tube for directing the shock waves into the shale reservoir, a perforated cylinder for releasing the high pressured shock waves on to the shale rocks and a plurality of packer systems for aligning the guide tube and the perforated cylinder inside the shale reservoir. The shockwaves creates a plurality of fractures on the shale rocks. The shockwaves further cause widening of the existing factures on the shale rocks.

What is claimed is: 
     
         1 . A system for fracking a plurality of shale rocks in a shale reservoir, the system comprises:
 a shock tube for generating a plurality of shock waves;   a support system for holding the shock tube;   a guide tube for directing the shock waves into a shale reservoir:   a perforated cylinder for releasing high pressured shock waves on to the shale rocks; and   a plurality of packer systems for aligning the guide tube and the perforated cylinder inside the shale reservoir.   wherein the shockwaves creates a plurality of fractures on the shale rocks, and wherein the shockwaves further cause a widening of the existing factures on the shale rocks.   
     
     
         2 . The system according to  claim 1 , wherein the shock tube comprises a driver section and a driven section separated by a metal diaphragm. 
     
     
         3 . The shock tube according to  claim 2 , wherein the driven section is filled with a low pressure driven gas, and wherein the driver section of the shock tube is filled with a high pressure driver gas supplied by a high pressure gas cylinders. 
     
     
         4 . The system according to  claim 1 , wherein the guide tube and the shock tube are connected by an elbow bend, and wherein the shock wave travelling through the driven section of the shock tube is directed into the guide tube through the elbow bend. 
     
     
         5 . The system according to  claim 1 , wherein the diaphragm is ruptured using the high pressure gas to produce the shock waves, and wherein the shock waves produced are propagated through the driven section. 
     
     
         6 . The system according to  claim 1 , wherein the diaphragm is busted to produce a series of shock waves, and wherein each shock wave possess a speed and wherein the speed of each shock wave is increased in multiples of a speed of sound, and wherein each shock wave is compressed to generate a shock that is propagated through the driven gas. 
     
     
         7 . The system according to  claim 1 , wherein the perforated cylinder is placed in a confined zone between the pluralities f packer systems to avoid a leakage of the shockwaves. 
     
     
         8 . The system according to  claim 1 , wherein the high pressure jets strike out the shale rock formation horizontally through the perforations of the cylinder. 
     
     
         9 . A method for frocking a plurality of shale rocks in a shale reservoir, and wherein the method comprises steps of:
 generating a plurality of shockwaves in a shockwave tube;   guiding the generated shockwaves into a shale reservoir through a guide tube;   electing high pressure shockwaves through a perforated cylinder attached to the guide tube; and   fracturing the shale rocks by exerting high pressure shockwaves onto the shale rocks,   wherein the high pressure shockwaves creates a plurality of fractures an the shale rocks, and wherein the shockwaves further cause a widening of the existing factures on the shale rocks.   
     
     
         10 . The method according to  claim 9 , further comprises steps of
 filling a driven section of the shock tube with a low pressure driven gas; and   supplying a high pressure driver gas to a driver section of the shock tube;   wherein the driver gas exerts high pressure onto a diaphragm thereby separating the driver section and the driven section, and wherein the diaphragm is ruptured to produce the shockwaves.
