The Gazprom Management Committee examined the availability of the Unified Gas Supply System (UGSS) facilities to operate during the peak loads of autumn/winter 2015 - 2016, as well as actions required to ensure uninterrupted gas supplies to domestic and foreign consumers in the winter period and thereafter.
The meeting noted that Gazprom’s comprehensive efforts before the cold season ensured reliable gas supplies to the Russian constituents and allowed meeting contractual obligations to the consumers within and beyond the CIS.
The measures to prepare the UGSS for winter 2015 - 2016 covered all 17 maintenance and overhaul programmes. By now, the company overhauled 952.3 km of gas pipelines and 247 gas distribution stations. During the last nine months, 15700 km of pipelines were subjected to inline inspection, 49 submerged crossings were repaired and 689 ones saw flaw detection. Besides, the company maintained 396 gas compressor units and restored 49 km of process tubing for compressor stations.
Rapid development of the underground gas storage (UGS) network is likely to raise the potential output of Gazprom’s domestic UGS facilities to the unseen level: the maximum daily deliverability in the early withdrawal season is going to reach 789.9 million m3 of gas, which is 19.5 million m3 higher as compared to the previous year. The increment of the maximum daily deliverability corresponds to the daily gas consumption by some Russian constituents in the winter period, for instance, the Vologda or the Leningrad Regions.
The UGS replenishment with as much gas as was withdrawn in the previous cold season and stockpiling of operating gas reserve in the Russian UGS facilities in the amount of 72.018 billion m3 are nearly completed. Taking into account the Armenian and Belarusian UGS facilities, Gazprom’s operating gas reserve will reach 73.209 billion m3.
Gazprom has so far injected 4.6 billion m3 into the European storages, 1.6 billion m3 – into the Incukalns UGS facility in Latvia. This is an extra guarantee for smooth operation during the peak load period.
Reliable functioning of gas production facilities is ensured, inter alia, by complete repair of 88 gas pre-treatment and comprehensive treatment units. 318 wells were overhauled by 1 October 2015. Besides, this year will see the commissioning of a gas boosting station at the Urengoyskoye field, as well as new wells at the Orenburg, Urengoyskoye, Yubileynoye and Yamburgskoye fields.
Moreover, successful passing of the peak load period depends on the availability of emergency fuel (fuel oil, coal, etc.) at power plants and major industrial companies, as well as thrifty gas consumption in the Russian regions.
Gazprom’s relevant units and its subsidiaries were tasked to complete timely preparation of the UGSS facilities for winter operation and ensure reliable and sustained functioning of process facilities.
