Gas gas drilling firms such as Shell, Hallibuton or Schlumber may be interested in this alternative green technology to chemical-based hydraulic fracturing, or "fracking," for shale gas drilling” which is called called Cavitation Hydrovibration-- in light of the proposed ban on fracking (NYC urges ban on shale gas drilling)
The cavitation hydrovibrator is a proprietary green technology that operates using pure water, without the use of any chemicals 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 variable, 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 gas liberation.
