A method includes installing at least one grounded electrode at a certain distance away from the well sufficient enough to avoid electrical breakdowns and connecting a high-voltage electric capacity meter to a wellhead and to said grounded electrode. A voltage pulse between the wellhead and the electrode. An electric capacity is measured before flooding and in the process of flooding. The oil formation water-flooding area radius value is determined by the flooded area capacity variation in time.

Method for determination of the oil formation's water-flooding area radius in the wellbore zone

The current invention provides an improved method of increasing well yield and enhancing oil production. The method comprises the steps of lowering a vibroacoustic downhole emitter into a well down to a production layer depth and performing acoustic impact on the formation. The impact is implemented by a multiple frequency signal containing at least two simple harmonic components whose frequencies and amplitudes meet the resonance overlapping condition.
