The relevance of the research is caused by the need to update and revise constantly the strategy of oil and gas enterprises economic efficiency by optimizing the costs of control and testing instrumentation, APCS and communication equipment maintenance. The main aim of the research is to develop a scientifically based approach to the automated maintenance time standard of control and testing instrumentation, APCS and communication equipment. The approach should allow reducing the time and increasing the overall efficiency of the maintenance planning process. Objects of the researches are technological installations of oil and gas production, preparation, pumping and storage, reservoir pressure maintenance; transport pipeline, equipment for automated process control systems; communication facilities: radio-relay and satellite communication systems, wired communication systems, fiber-optic communication lines, telephone exchanges, trunk communication systems, video surveillance and alarm systems. Methods. To automate the formation of labor standards for maintenance of new equipment, the method of classifying equipment into categories of technical complexity was used. Results. The authors have developed the automated calculation method for maintenance of labor cost standards. The method is based on the categories of technical complexity. The requirements for formation of software basic labor norms were determined. On the basis of the proposed methodology, basic labor standards for control and testing instrumentation, APCS and communication equipment maintenance were formed (within Tomskneft company).
