Gazprom Neft has acquired five geological prospecting licenses to “flank” fields — already under exploration or development — in the Yamalo-Nenets Autonomous Okrug.* All of these new blocks will be developed by Gazprom Neft subsidiary Gazpromneft-Noyabrskneftegaz. All licenses have been issued for a period of seven years.
Gazpromneft-Noyabrskneftegaz will investigate the 552.6-km2 Novogodny-2, the 496.9-km2 Zapadno-Yarainersky, and the Zapadno-Ety-Purovskoy and Privolny blocks, covering 992.5 km2 and 451.7 km2, respectively, all located in the Purovsky district of the Yamalo-Nenets Autonomous Okrug, and all of them “flank” fields adjoining the Novogodnee, Yarainerskoye, Ety-Purovskoye and Ravninnoye fields. A further new asset — the Zhigulevsky block — is located in the Krasnoselkupsky district of the Yamalo-Nenets Autonomous Okrug and is a flank field adjoining the Kholmistoye field. This block covers an area of 362 km2.
2D seismic investigations have already been undertaken at all of the recently acquired license blocks. Investigations will continue in 2021 in order to clarify the blocks’ resource potential and formulate the optimum geological prospecting programme.
“The Yanalo-Nenets Autonomous Okrug’s Noyabrsky district is a landmark for Gazprom Neft. Our history started here, and it was the Noyabrsky businesses that subsequently became the launch pad for the company’s advance into the Arctic. Most fields in Noyabrsk are now at an advanced stage of development, but — helped by modern technologies and development strategies — we are maintaining stable production volumes there and, through these new blocks, are developing a base to ensure production in the region, going forward.”Vadim Yakovlev Deputy CEO for Exploration and Production, Gazprom Neft

** The Novogodnee field lies north—east of Noyabrsk. Active development of oil-bearing strata started here in 1992, with cumulative production now standing at 8.5 million tonnes.
The Ety-Purovskoye field, under development since 2003, is one of Noyabrskneftegaz’s most remote fields. More than 16.6 million tonnes of oil have been produced over the years in which it has been under development.
The Yarainerskoye field is located in the Purovsky district of the Yamalo-Nenets Autonomous Okrug, 140 km east of Noyabrsk. Commercial production commenced in 2000, with cumulative production now standing at 10 million tonnes.
The Ravninnoye and Kholmistoye fields form part of the Otdalennaya-group cluster. These fields are being developed on a standalone basis: deliveries are only possible during winter, on seasonal ice-roads. The Otdalennaya-group cluster is one of the key drivers in Noyabrskneftegaz’s development, with more than 10.8 million tonnes of oil having already been produced here. With a resource base of 56.8 million tonnes, active geological prospecting is currently ongoing.
