Benefits of technology
The present invention involves a device that prevents shockwaves from leaking in a specific area between packer systems. This device is a perforated cylinder that is placed in a confined area to prevent the shockwaves from escaping. The technical effect of this invention is to improve the stability and accuracy of the shockwave treatment process.
Problems solved by technology
The availability of petroleum and its products are getting depleted day by day.
This water is polluted with chemicals, salts and even mild radioactivity.
Hydraulic fracking is also a highly tedious process which requires high skilled workmanship.
In that case the hydraulic fracking technique becomes impossible to carry out.
This technique also involves chemical treatment process and is considered highly uneconomical.
Carbon dioxide fracking poses many challenges besides the lack of infrastructure.
So it is more difficult for gases to reach the pressure needed to fracture the rock.
Also, the carbon dioxide has to be separated from the natural gas before shipping the fuel to market, which adds to costs.
And it is probably never economical to install carbon dioxide pipelines all the way to every fracking well.

Embodiment Construction
[0011]The primary object of the present embodiment is to provide a system and method to create fractures M a plurality of shale reservoir rocks and also to extend the dimensions of existing fractures by using a plurality of shock waves.
[0012]Another object of the present embodiment is to provide a system for generating the shockwaves on ground and directing the waves into borewell.
[0013]Yet another object of the present embodiment is to provide a system that produce the shockwaves at the point of application inside the borewell, by using combustion of gases.
[0014]Yet another object of the present embodiment is to strike the high pressure shockwaves onto the Shale rocks with a high velocity for creating a plurality of fractures along the weak zone of the shale formation.
[0015]Yet another object of the present embodiment is to widen the existing fractures in the shale rock formation using the shock waves.
[0016]These and other objects and advantages of the present embodiment will becom...

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.
