METHOD OF OIL PRODUCTION INTENSIFICATION Russian patent published in 2015 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: method includes vibration impact on the oil reservoir by the resilient oscillation sources. For this on ground surface near the wellhead of the production well the oscillation sources of same frequency are installed. Near the external boundary of the specified well the oscillation sources of same but higher frequency are also installed. Simultaneous impact of oscillations from all sources on the oil reservoir is performed with intensity, time of impact and oscillations interference ensuring coagulation of oil drops in porous space of the oil reservoir with water and directed flow movement due to difference of frequencies of the oscillation sources towards wellhead of the production well. At that contracting effect of the directed flow movement towards the wellhead of the production well is specified by number of sources of the resilient oscillations in the external boundary of the production well.

EFFECT: increased oil extraction due to reduced filtration resistances during water-oil emulsion movement via the porous environment.
