The Yuzhno-Russkoye field stands at the forefront of the industry in technological and engineering solutions.

Severneftegazprom’s gas treatment facility is a highly automated complex, one of the most sophisticated in Russia. It is outfitted with advanced domestic and foreign equipment that combine high precision technology, automation, and design solutions.

The information management system of Yuzhno-Russkoye field, built on the basis of the Siemens SIMATIC PCS7 software and hardware complex, allows to provide the most efficient performance of the Yuzhno-Russkye field technological processes, operational control of the main and auxiliary production from a single control panel, instantly notify operating personnel of technological process deviations, prevent the development of abnormal and emergency situations. To solve the problems of optimal and rational management of technological processes with minimal consumption of material and technical resources and equipment operating time, a complex of mathematical tasks was specially designed and implemented with a positive result, which generates control processes that combine the necessary sensors, actuators, data transmission channels of various automation systems, and ensures their interaction with each other under the control of operating personnel.

For example, the automatic control of Gas Treatment Unit (GTU) capacity is implemented as a control loop in which the actuators are Gas Compressor Units No. 1, 8, while the BCS-1 implements the stabilization function: maintaining the required value of the commercial gas flow rate. Workshop control is carried out through the set-up of tasks for the rotational speeds of the Gas Processor Unit (GPU) superchargers. The calculated values ​​of the tasks that control the fuel metering units of gas-turbine drives with the provision of the optimal consumption of fuel and energy resources are fed to the Automated Management System of Gas Processor Unit (GPU). The source of information for the feedback channel is the value of the flow rate of the prepared and dried gas measured at the Gas Metering Station.

Eight natural gas dehydrators with modernized internal devices are manufactured according to the joint technical proposal of the companies LLC Gazprom VNIIGAZ and Zulzer Chemteh. The use of special internal devices made it possible to reduce the entrainment of triethylene glycol, to improve machine performance and the quality of gas drying. In addition, to manage the natural gas dehydration process, a mathematical task was developed and tested with a positive result to ensure the required dew point at the gas treatment plant, according to the STO Gazprom 089-2010. The solution of the task is based on mathematical models of gas drying with the implementation of periodic monitoring and adjustment of absorption coefficients with the help of its own accredited chemical-analytical laboratory. The complex of tasks for managing the natural gas dehydration process allows maintaining the desired dew point temperature at the GTU output automatically around the clock with minimal consumption of triethylene glycol (0.8 g / 1000 m3), as well as providing the operating personnel of the Gas Treatment Unit (GTU) with information on the quality and efficiency of the gas treatment process in each absorber, and on GTU in general.

For the first time among the companies of the PJSC Gazprom group, a high-tech equipment complex was used at the booster compressor station of Yuzhno-Russkoye field, consisting of eight gas pumping units 16DKS-09 Ural, equipped with a gas turbine unit with an aircraft engine manufactured by ODK-Perm Motors JSC, and natural gas blowers produced by PJSC NPO Iskra with a system of magnetic suspensions of the S2M company and dry gas seals of the John Crane company, which made it possible to establish a record horizon and which was the goal of many companies in gas industry of the Russian Federation. In turn, for OJSC Severneftegazprom, the equipment complex of the booster compressor station made it possible to implement new innovative solutions and set a goal to be always one step ahead. The system for managing technological losses of gas after a dry gas seal (DGS), a method for technical diagnostics of a gas turbine unit, a shaft layout for centrifugal compressor with an additional safety bearing are only the small part of the achievements OJSC Severneftegazprom specialists to increase the reliability of equipment operation of the booster compressor station, cut the Company's economic costs, and reduce the negative impact on the environment.

The commercial gas metering station, located at the gas metering station, was built with the use of an ultrasonic flow meter complex KOS FCS 212 based on KOS FPM 207 controllers manufactured by FMC Kongsberg Metering AS, and consists of four measuring lines with MPU ultrasonic flow transducers 1,200 (DN 500) for commercial accounting and two lines (DN 150) for own needs, used for planned shutdown of the Gas Treatment Unit (GTU). The permissible relative measurement error of commercial gas metering station is ± 0.55%.

The electric station providing energy for the field is equipped with eight independent gas-turbine plants “OPRA”, which ensure the production of the power required for the gas field and distinguished for their reliability in operation and high performance by thermal, technical, economic and environmental indicators.

To meet the needs of the gas field with drinking water that complies with the requirements of Sanitary Rules and Regulations, an integrated method for purifying water of complex composition using the vacuum degassing installation SVDV 500 followed by the treatment at the Impuls 10/20 station was applied. The implemented technologies allowed to achieve the compliance of water quality with the established requirements of 29 indicators.

Purification of industrial and rainwater wastewater containing a water-methanol mixture is organized at the Flottweg plant, which includes: tricanter (the centrifuge) and a disc sentrifuge. The unit is equipped with purging system (nitrogen), which ensures a safe process of cleaning wastewater containing methanol.

The Company uses modern digital technologies: radio-relay communication systems Haris, Pasolink; automatic telephone exchanges Avaya; technological dispatch communication Industronic. For the first time among the companies of the Gazprom Group, in 2007, the Tetra standard digital trunking radio system was commissioned. The developed radio coverage area of ​​Tetra at Yuzhno-Russkoye field and the modern capabilities of subscription stations made it possible to implement a GPS monitoring system of controlled objects - working duty shifts, mobile teams and vehicles. The interactive map of the main control system central workplace tracks the location of objects, the trajectory of movement, as well as various alarm events, including the fall of the employee.

In 2018, an integrated multi-level interactively-automated system of communication equipment monitoring was implemented by own means, both on the territory of the Yuzhno-Russkoye field and at remote sites, which allows to keep under control the operation modes of various types of equipment and communication systems in general.

At all stages of the production process the Company uses modern control systems with the most advanced software and hardware complexes.
