Usage Ultrasonic Technology to Improve Oil Recovery with an Environmental Aspect

A new method for the ultrasonic enhancement of oil recovery from failing wells is described. The technology involves lowering a source of power ultrasound to the bottom of the well either for a short treatment before removal or as a permanent placement for intermittent use It is proven by recent studies that sonication has a positive influence over the oil flow within the porous media. Accordingly, in this paper evaluated the influence of sonication over the oil recovery by means of free fall gravity drainage. Furthermore, the influence of sonication on the oil permeability was assessed in three samples that had different bead size in average. By use of the Hagroot backward method and Matlab simulation,the optimal petrophysical situation for sonication was determined. Furthermore, it was witnessed that gravity drainage was heightened by increase of beads’ size in the non-asphaltenic sample
