The gas turbine power plant of East-Messoyakha field has passed a one-year boundary of operation on associated gas

16 April 2018



The northernmost continental gas turbine power plant in Russia has been operating in the Yamal-Nenets Autonomous Area since September 2016. Its operator is JSC Messoyakhaneftegaz, a joint venture of Gazprom Neft and Rosneft.

84 MW GTPP supplies electricity and heat to the production and infrastructure facilities of the field. The basis of the plant is six gas turbine units of type Titan 130 manufactured by Solar Turbines Inc. with a unit capacity of 14 MW.



At the first stage GTPP operated on natural gas, and since April 2017 as a fuel for turbines there is used associated petroleum gas produced at the field.

This was made possible by commissioning a fuel gas treatment facility (FGTF) of the ENERGAS Company. FGTF provides the required quality of associated gas in accordance with the established parameters on purity, temperature, pressure and flow rate.

According to the project, process equipment is placed inside a separate capital building.



To compress gas FGTF includes four booster compressor units. These CUs compress the low-pressure (0.2...0.45 MPa) APG to 2.95...3.05 MPa. The capacity of each unit is 9,000 m3 / h.

For gas purification high-efficiency filters-scrubbers are designed, which are located at the inlet to the CU and perform 2-step removal of liquid fractions and solid particles. The efficiency of the filter elements is 100% for contaminations larger than 20 microns and 97% for particles 5...20 microns in size.

At the discharge line of the CU there is built gas coolers so as to cool gas below the dew-point in order to separate condensate formed. Then the gas flows to the heaters, which maintain the design temperature of the fuel feeding to the turbines.



Each compressor unit is equipped with a two-level system of capacity control and automated control system. FGTF is additionally equipped with dew-point measurement system.

The implementation of this project ensured stable and sustainable operation of GTPP turbines at the actual associated gas parameters, and also increased the percentage of APG recovery (rational use) at East-Messoyakha field.



REFERENCE. The group of Messoyakha fields includes East-Messoyakha and West-Messoyakha fields. The recoverable oil reserves are estimated at 620 million tons in total. The bulk of the reserves fall on extra-heavy crude oil.

The fields were discovered in the 1980s and are the northernmost of the known Russian fields on land. The Messoyakha group is located on the Gydan Peninsula, in the Tazovsky District of the Yamal-Nenets Autonomous Area, 340 km north of Novy Urengoy - in the Arctic climatic zone.

The first oil from the East-Messoyakha field was obtained in October 2012 in the framework of pilot industrial works. Full-scale development of the asset began in late 2016. According to preliminary estimates, the peak of production will be reached by 2022-2023 and will amount to 10 million tons of oil and 5 billion cubic meters of gas per year.
