DEVELOPMENT METHOD OF HIGH-VISCOUS OIL DEPOSIT Russian patent published in 2012 - IPC E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: method implies drilling of formation, solution pumping to formation with its simultaneous treatment by high-frequency electromagnetic field transferred from generator to bottomhole emitter. Formation is drilled by making at least one well. Electromagnetic energy is transferred via feeder and short-circuited metallic faceplate to which the following is hanged: string of tubing, centring dielectric bead, metallic stock closed to tubing at a distance of quarter-wavelength (the stock is being an extension of feeder inner conductor), dielectric beads. At first well is set to delivery mode. Then well soaking is performed without any impact. Then well is set to mode of extraction and mixture of oil and solution is removed from formation without high-frequency electromagnetic action.

EFFECT: improving efficiency and profitability, increasing oil recovery.
