Authors: V.N. Gusakov, N.N. Kraevsky (RN-UfaNIPIneft LLC, RF, Ufa), A.N. Nikitin, S.A. Palchik (RN-Yuganskneftegaz LLC, RF, Nefteyugansk)

Key words: near-wellbore stimulation treatment, buffer pad, mutual solvent, diverter, well completion, selective treatment, well intervention, abnormally low and high formation pressure

The current paper includes the results of the research project aimed to increase the effectiveness of near-wellbore stimulation treatment technologies at abnormally low and high formation pressures in the region of RN-Yuganskneftegaz activity. Potential applicability of different technological solutions is quantified using filtration experiments, the most promising ones are chosen for implementation. The results of pilot field testing conducted as a part of the project approves the efficiency of developed solutions and can help to adjust technologies to the field conditions in the region of RN-Yuganskneftegaz activity.
