The geological and technological parameters, which have a prevailing influence on the success of the treatment, were established on the basis of analysis and synthesis of experience of hydrochloric acid treatments in the conditions of Tournaisian oil deposits of the Volga-Ural oil and gas-bearing province. The algorithms, which allow selecting wells for hydrochloric acid treatment, determining the parameters of treatment taking into account peculiarities of geological structure of formations, time factor, peculiarities of technology of wells and deposits operation, were proposed. The conditions for the most successful implementation of this type of treatment on the bottomhole zone to intensify oil production and reduce the water cut in order to increase the level of profitability of deposits in carbonate reservoirs with hard-to-recover reserves were established.
