OAO "Ulianovskneft" intensifies oil production at Alagulovskoye oilfield.
Ulianovsk. OAO "Ulianovskneft" is intensifying oil production at Alagulovskoye oilfield. At the present moment it is decided to test the method of acoustic impact on a well at well No 213.

The essence of the method is as follows: directed impact of  elastic ultrasonic frequency field  over the formation and well  structure. The impact of ultrasound results in cleaning the canals in  porous structure of the bottom-hole zone from paraffin and asphaltene sediments and various mechanic particles. Powerful ultrasound reduces oil viscosity which permits to remove destroyed bridging agents easily. Besides, the elastic field used for treatment, does not harm  the structure of the well.
In case of stable growth of the flow rate  at well No 213 of Alagulovskoye oilfield the company will consider further application of acoustic impact at its other oilfields.
