OIL RECOVERY INTENSIFICATION METHOD AND NON-OPERATING OIL WELLS RECOVERY USING RESERVOIR ELECTROMAGNETIC RESONANT TREATMENT Russian patent published in 2010 - IPC E21B43/16 

FIELD: oil-and-gas industry.

SUBSTANCE: according to a method, generate in a reservoir modulate electromagnetic vibrations with a help of surface or well located electromagnetic waves generators, directed from a production well and opposite, at least from one neighbouring well to one production well. Overlap generated opposite electromagnetic fluctuation with a help of control devices and a generator-receiver, located on the surface, on a hydrocarbon own vibration frequency, creating resonant vibration frequency, which generates hydrocarbon fluids molecules and atoms vibration with a pick resonant amplitude in vertical, horizontal and other plane. Direct each of hydrocarbon fluid generated molecules or atoms pick resonant vibration, in their hitting with collector skeleton process, towards to the production well with repeating runs. For runs initiation primary set up a rate on a vibration flow from the production well, which significantly exceeds flow rate of each opposite vibration flow, taking into account attenuation coefficients. Further more the vibration flow rate from the production well smoothly decreasing with simultaneous proportional smooth flow rate increase of each opposite vibration flow. At the process beginning localise the pick resonant appearance zones near by the neighbouring wells, at the nearest place of hydrocarbon fluid, blocked with reservoir water, location in the opposite to the production well point, then moving it towards the production well in a forced control regime.

EFFECT: oil recovery efficiency increase due to oil recovery factor increase not only for operating wells, but also for wells under lasting stand by.
