Pyakyakha oil and gas condensate field of the LUKOIL-West Siberia LLC has been equipped with compressor station (CS) for gathering and transportation of associated petroleum gas. As a part of CS, there will be operate nine compressor units (CU) of various types and purposes, which were supplied by the company ENERGAS.

Among them the low-pressure CU for compression of APG of the second oil separation stage (from the oil treatment plant) and gas from the terminal separation unit. Capacity of CU varies in the range of 101…2,160 m3 / h and it is controlled by two-tier regulation system.



Block-modular unit is designed to meet the extreme operating conditions (minimum air temperature is minus 56°C, average air temperature of the coldest five-day period is minus 46°C).

CU operates in automatic mode; it is equipped with life support systems (heating, ventilation and lighting) and safety systems (fire detection and fire fighting, gas detection). To measure of compressed APG amount, unit is additionally equipped with gas metering station with flow meter.

Commissioning of the compressor unit took place after a 72-hour comprehensive testing as a part of the facility. The whole set of pre-operational works, including erection supervision, starting-up and adjustment, individual tests of equipment, was performed by the engineers of ServicENERGAS LLC (companies group ENERGAS).

REFERENCE. Development of Pyakyakha field is the second project for the production of hydrocarbons, which LUKOIL-West Siberia has implemented in the Yamal-Nenets Autonomous Area. The company started commercial production of gas in YNAA in 2005, when Nakhodkinskoye field was put into operation.

Pyakyakha field refers to the most promising fields of Bolshekhetskaya Depression. Its reserves for the beginning of 2014 are 69.5 million tons of oil and 234.2 billion cubic meter of gas.
