Problem Statement
- Oil and gas production in wells that are ceased or cemented with particles and fluids of muds and slurries are stimulated by sharp decline in pressure to enhance cleaning of mudding off and bridging pay zone for disclosure of existing cracks and formation of new.
- Existing methods either generate insufficient pressure drops or require the use of complex equipment.
- There is a need for a method of versa fracking for enhanced oil and gas recovery through the use of decreased pressure and simple equipment
Technology
- Impacting versa fracking in the bottom hole of a well reservoir.
- Running tubing filled with air under pressure of 1 kg/cm2 or under atmospheric pressure or connected to the atmosphere into the bottom hole of the well using cable
- The lower end of the tubing is closed with a black flange or diaphragm whose strength is equivalent to the hydrostatic pressure in the well plus 5 – 25 kg/cm2.
- Versa fracking shock is impacted to the reservoir by perforating or destroying with the use of increased pressure in the well in the range of 5 – 25 kg/cm2 the black flange or diaphragm installed on the lower side of the tubing with the use of a shaped charge to provide a hydrodynamic link in the bottom hole.
- Finally he tubing is pulled from the well with the help of a metal wire rope or a cable logging or coiled tubing.
Key Features / Value Proposition
- The above described method of versa fracking enhances oil and gas recovery by power comparable to the impact of hydraulic fracturing.
- The Versa fracking method uses an equipment with simple construction and generates sufficient pressure drop for effective fracking. Whereas conventional methods require complicated equipment
- The method does not require the use of external energy source but depends wholly on the differential pressure between atmospheric pressure and formation fluid pressure
- Versa fracking technology is significantly cheaper than the usual hydraulic fracturing and does not pollute the environment.
