The adjustment works and tests of the gas turbine power plant at the Rogozhnikovskoye oil field of Surgutneftegas OJSC were completed. Thanks to the new equipment, associated gas, previously flared, is used to generate electricity needed for the operation of its own facilities of the oil and gas production complex. The installed capacity of the GTPP is 36 MW.

In its composition there are operating three power generating units based on NK-16ST gas turbine engines with a rated capacity of 16 MW each (manufactured by KMPO) with turbo-generators with a capacity of 12 MW (Electrotyazhmash-Privod). The power generating units were manufactured and then mounted at the facility by specialists of OJSC Sumy NPO named after M.V. Frunze.



A hangar-type compressor station consisting of three booster compressor units (BCU) provides fuel supply to the turbines. BCUs with capacity of 5,000 m3 / h compress associated petroleum gas of medium pressure (from 0.4 to 2.8 MPa) coming from the Central Production Facility.

The units are equipped with two-level capacity control systems, individual ACS, as well as a group system of automated control and monitoring integrated into the GTPP APCS. The operating mode of the BCU as a part of the object is continuous, with scheduled stops for maintenance.



Final gas purification at the inlet to each compressor is provided by highly efficient separators – two-stage filters-scrubbers with automatic drainage system. It is possible to quickly replace filter elements.

Compressor units also maintain the design temperature of fuel feeding to the combustion chambers of turbines. In accordance with the project, BCUs are located in separate capital building, complete with life support and safety systems.



The supply and the whole set of works on commissioning of this equipment were provided by ENERGAS.

The plans of Surgutneftegas OJSC envisage the construction of the second stage of the auxiliaries power plants of the Rogozhnikovskoye field. The construction of GTPP-2 will increase the electricity supply by another 36 MW. It is also planned to equip the production facility with a compressor unit with a diesel drive intended to restore the operating mode of power generating units in the absence of power. These projects are planned to be completed before the end of 2010.

REFERENCE. The Rogozhnikovskoye field is located in the Oktyabrsky district of the Khanty-Mansi Autonomous Area. It is in operation since 2005. The development is carried out by the Bystrinskneft Oil and Gas Production Department of Surgutneftegas OJSC. The main difficulty for oilmen is the distance of the oilfield from the city of Surgut to a distance of almost 400 kilometers, as well as difficult geological and climatic conditions.
