A Green Alternative to chemical-based hydraulic fracturing, or fracking for shale gas drilling-Cavitation Hydrovibration

Gas drilling firms such as Shell, Halliburton or Schlumberger may be interested in this alternative green technology to chemical-based hydraulic fracturing, or "fracking," for shale gas drilling” which is called Cavitation Hydrovibration-- in light of the proposed ban on fracking (NYC urges ban on shale gas drilling)

One of my clients, tha university in Ukraine, which is part of the National Academy of Sciences of Ukraine and the National Space Agency of Ukraine, has developed a technology called a cavitation hydrovibrator, which is designed to fracture rock, using a pressurized water pulse action on rock stratum to increase its degree of fracturing.

The cavitation hydrovibrator is a proprietary green technology that operates using pure water, without the use of any of the 200 chemicals traditionally used in fracking that damage the environment and contaminate water tables. The cavitation hydrovibrator is mounted in a drilling line and inserted into a vertical or horizontal borehole at the appropriate stratum level. Pressured water is fed to the cavitation hydrovibrator inlet through the drilling line using a drill pump. Then the water passes through the hydrovibrator flow passage and enters the borehole where the gas-saturated stratum is located. Due to the pressure differential across the hydrovibrator, the regime of periodically detached cavitation is set up in its flow passage. In this regime, the steady water flow is transformed into a high-frequency pulsating flow.The pulse-repetition frequency can be varied from 100 to several thousands Hz. This frequency is governed by the geometry of the hydrovibrator and the pressure differential across it which can be precisely controlled. The water pressure pulse acts on the gas-bearing stratum and increases its degree of fracturing, with the radius of action being relatively large. This enhances the liberation of gas.

This method has been tested and used in the Novojarovskoje sulfur deposit (in the Lviv Region, of Ukraine), where sulfur is extracted by the Frasch process. As well, this method has performed remarkably in the recovery of old water wells in the Moscow Region and the Pskov Region (in the Russian Federation) and in Kazakhstan.

One of the researchers said:

"The cavitation hydrovibrator has not been used to extract gas as such. However, chemicals were also in common use to increase the filterability of sulfur deposits. Field tests of the hydrovibrator have shown that chemicals can be dispensed with. Thus we believe that the hydrоvibrator will do in the case of gas-saturated strata as well."

Eliminating the fracking fluid is great but how effective is this new technology at controlling secondary fractures that allow the gas itself to escape into wells, water tables and surface water like creeks where it can disrupt ecosystems and come out through someone's faucet? The gas itself is poisonous as well.
