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.
