Gazprom Neft has commissioned a 20-billion cu m/year (bcmy) subsea natural gas pipeline in the Russian Arctic, connecting production from Novoportovskoye field on Yamal Peninsula to the Yamburg-Tula gas trunk pipeline, part of Russia’s Unified Gas Supply System (UGSS). The company said that commissioning the 115.5-km pipeline opens opportunities for developing a major oil and gas cluster in the southern Yamal Peninsula, projecting potential incremental production of as much as 20 bcmy of gas and 10 million tonnes/year (tpy) of oil.
The pipeline will run 58.4 km across the Gulf of Ob, 5 m below the seabed. Novy Port residents will be connected to the UGSS as part of the project.
Gazprom is also building a gas processing plant. In addition to natural gas, it will process condensate and associated petroleum gas (APG). The company expects to be able to use up to 95% of produced APG.
The project’s total cost is more than ₽150 billion ($2 billion).
Novoportovskoye field is in the Yamalsky District of the Yamalo-Nenets Autonomous Okrug, 30 km from the coast of the Gulf of Ob. Recoverable reserves stand at 248 million tonnes of oil and condensate, and 266 bcm of gas, according to Gazprom. A total 14.87 million tonnes of oil equivalent were produced in 2020, 5% more than in 2019.
Full-scale production drilling at Novoportovskoye field started third-quarter 2014. Gazprom describes oil produced at Novoportovskoye field, Novy Port crude, as a unique light (35° API) low-sulfur (~0.1%) grade.
