New approaches to the technology of acid treatment of the bottomhole zone without setting up of workover

   The article considers the experience of applying bottomhole zone treatment technology without setting up of workover, and reveals the problem of a lack of significant effect of the measures. Proposals for the simplification of technology have been formulated, an instruction for implementation and a register of designs of contactless treatments for solving a wide range of tasks related to bottomhole zone treatment has been developed. Following the selection of candidate wells and the testing of the developed approaches, a benchmarking exercise was conducted at LUKOIL-West Siberia LLC. The work performed led to an increase in the efficiency and economic profitability of contactless treatment.
