The first facility of LUKOIL's own generation at the fields of West Siberia celebrated 10 years of uninterrupted operation

10 May 2018

The gas turbine power plant of the Vatyegan field passed 10-year boundary of uninterrupted operation. This is the first facility of the own generation of PJSC "LUKOIL" in the territory of West Siberia. Since the commissioning in April 2008, a 72 MW GTPP has long been the largest power plant of the company's own needs.


The GTPP, built by LLC "LUKOIL-West Siberia", uses associated petroleum gas as a fuel. Thus, the provision of energy for the field infrastructure is combined with the recovery of APG. As a result, 1.4 billion cubic meters of associated gas were productively used for 10 years.

The plant includes six power units of EGES-12S-01 with a capacity of 12 MW each. The power units are based on gas turbine units GTU-12PG-2, designed by JSC "UEC-Aviadvigatel" and manufactured by JSC "UEC-Perm Motors".

In the design and construction there is realized a number of new design solutions. Among the features of the Vatyegan GTPP they can mark the following:

  • turbine-generator and reduction valve are made on a single frame;
  • there is used a separate turbine-generator protection unit;
  • ACS of power units are combined into a common information network for remote control and operation control of all units;
  • in each turbine room there are symmetrically placed two power units ("left" and "right" version).

The pairwise units placement in turbine rooms that is used here for the first time is further used in many of LUKOIL's own generation facilities.


A significant contribution to the reliability of GTPP-72 operation is made by the fuel gas booster compressor station (BCS) of ENERGAS. Four hangar type units compress low-pressure (0.15 MPa) associated gas and feed it to turbines at a pressure of 2.7 MPa.

The post-treatment of APG at the inlet to each compressor is carried out by highly efficient coalescing filters-scrubbers equipped with automatic condensate drainage system. The process scheme of the BCS also provides for a stable maintenance of the design gas feeding temperature to GTU.

The unit capacity of the compressor units is 12,800 m3/h; gas flow is controlled by a special two-level regulation system. Start of BCS was performed by specialists of LLC "ServicENERGAS".


The equipment of the ENERGAS Group of Companies reliably operates as part of several power facilities at the fields of PJSC "LUKOIL". Among them there are Yuzhno-Khylchuyuskaya and Tevlinsko-Russkinskaya GTPP, GTU-CHPP "Usa" and "Yarega". In total, in the oil and gas industry, gas supply of turbines at 21 power supply centers for own needs of the fields is provided by 73 process units of ENERGAS.

REFERENCE. The large Vatyegan oil field is located in Khanty-Mansi Autonomous Area 140 km north-east of Surgut and 30 km east of Kogalym. Opened in 1971, its name was given by the name of the river Vatyegan. The development began in 1983. The development is led by the territorial industrial enterprise "Povkhneftegaz" of "LUKOIL-West Siberia".
