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.

An apparatus and seismic method for producing an shock wave in an oil well borehole, with a pumping unit arranged at the wellhead, a tubing string extending downward into the production casing of the well, a hollow cylinder assembly connected with the bottom of the tube string, and 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 an upper cylinder, a lower cylinder below the upper cylinder, a crossover cylinder below the upper and lower cylinders, and a compression chamber cylinder containing a compression chamber arranged between the crossover cylinder and the upper cylinder. The lower cylinder is adapted to receive the lower plunger, and the upper cylinder is adapted to receive the upper plunger. The lower plunger has a larger diameter than the upper plunger, and the plunger movement effects the volume of the compression chamber by reduction, the liquid contained therein becomes compressed and is discharged on the down stroke into the well.

The method and apparatus for making a micro-dispersed gas-liquid mixture which includes a gas-liquid ejector unit, a cavitation unit and a jet dispersing unit installed in a sequence. All above referenced units are installed into a cylindrical housing which in turn includes bottom and top covers and also has a first partition having a conical orifice separating a gas-liquid ejector unit from a cavitation unit and a second partition separating a cavitation unit from a jet dispersing unit. The gas-liquid ejector unit has an inlet located at the bottom of the cylindrical housing for liquid and the inlet located on side surface of housing for gas, these being between bottom cover of the housing and the first partition. In addition, the inlet for liquid is a nozzle the top having both outside and inside parts of which are adapted to the conical orifice of first partition to provide a required flow-rate of an ejected gas through the gas inlet. The gas-liquid ejector unit communicates through the conical orifice of the first partition with a cavitation unit comprising a hollow cylindrical cavitation chamber having at least one tangential inlet allowing a gas-liquid mixture from a gas-liquid ejector unit to flow inside the hollow cylindrical cavitation chamber for breaking of gas bubbles and further to a jet dispersing unit through an orifice of second partition for additional dispersing and homogenization.
