Abstract: A hand held hydro-suction vibration bio-stimulator submerged below surface of fluid in the fluid filled vessel and connected to the pump by means of flexible hose to derive the periodical suction force in the range of 0.5-70 N on the frequency of 10-200 Hz and high frequency vibrations in the range of 1-20 kHz to a living organism also submerged under the surface of the fluid in the fluid filled vessel due to the circulation of the fluid from the fluid filled vessel through the hydro-suction vibration bio-stimulator.

Abstract: A process is provided to enhance fluid production, recovery, and/or injection from and/or into fluid-bearing formations. The process includes the stimulation of the formation by vibrations, generated by the vibration source installed in the vicinity of the productive layer so that the stimulation is performed on the frequency coinciding with the eigen frequency bandwidth of filtration process of productive layer/sublayer.

Abstract: An apparatus for producing a shock wave in a borehole, such as a well, includes a pumping unit arranged at the wellhead, a tubing string extending downwardly into the production casing of the well, a hollow cylinder assembly connected with the bottom of the tubing string, and a pair of plungers arranged within the cylinder assembly and connected with the pumping unit with sucker rods and a polish rod for compressing liquid contained within the cylinder assembly and discharging the compressed liquid into the production casing, thereby generating a shock wave. The cylinder assembly includes a hollow upper cylinder, a hollow lower cylinder arranged below the upper cylinder, a crossover cylinder arranged between the upper and lower cylinders, and a compression cylinder containing a compression chamber arranged between the crossover cylinder and the upper cylinder.
