Article is devoted to generalization of the results of reorientation refracturing method carried out on Prirazlomnoye and Priobskoye oilfields (RN-Yuganskneftegaz LLC) for solving the stimulation of the formation. Geophysical logs confirmed the fact of the reorientation refracturing in five wells. The proposed indirect methods of diagnosing the reorientation refracturing increase the accuracy of the interpretation. The technique allows to control the reorientation refracturing by creating the necessary depression and calculating the time of stimulation.
