Objective and Scope
Purpose of work is to describe current methods for ultrasound oil well stimulations and possibility of ultrasound pipelines cleaning from asphaltene-paraffin deposits. This study based on theoretical process analysis, experimental investigations andfield tests.

Methods, Procedures, Process Paraffines, asphaltenes, particles and other wellbore damage are plugging pore spaces. Oil wells are not producing at their potential capacity. Deposits are plugging inside surface of pipelines, what reduces their efficiency as well. By application of ultrasound, the cleaning mechanism of micro acoustic streaming begins in the pore space. The ultrasound’s high power disrupts the adhesive forces that hold the particles in place. Consequently, these particles get removed. Pore space and initial permeability are restored, resulting is an increasing oil flow and cost-effective production and transportation.

Results, Observations, Conclusions
In this work is proven that ultrasound:
– Remove paraffines, wax and asphaltenes deposits;
– Destruct salt formations in the capillaries;
– Reduce surface tension in the capillaries;
– Destruct colloid formations;
– Decontaminate borehole;
– Might be used for pipeline cleaning;
– Might be used for tank cleaning.
Field tests has shown real increase of oil production.

Pipeline application is possible, but new type of system required for more efficiency results.
Novel/Additive Information
Field tests demonstrate that theoretical and experimental studies are right, but should be improved.
According to current rules and regulations number of possible technologies for oil well stimulation is decreasing. The biggest advantage for petroleum industry is that this technology completely environmentally friendly
