Gazprom Neft reviews information on the implementation of its offshore projects

The Gazprom Neft Board of Directors reviewed information on the company’s programme for offshore development on 14 December 2018.

One of Gazprom Neft’s key projects concerns the development of the Prirazlomnoye field on the Russian Arctic Shelf. Preliminary data indicates that cumulative production at the Prirazlomnoye field will reach more than nine million tonnes by the end of 2018. The outlook for developing this asset is predicated on developing Silurian and Devonian deposits located beneath the main reservoir at the Prirazlomnoye field.

The company is developing a new production cluster offshore from Sakhalin Island, where a new offshore field, Triton, was discovered at the Ayashsky block in 2018, with reserves in place estimated at 137 million tonnes. Estimated reserves in place at the Neptune field, discovered in the Ayashsky formation a year earlier, have been increased to 415.8 million tonnes of oil (C1+C2), a 1.6-fold increase on initial estimates. Gazprom Neft’s discoveries offshore from Sakhalin have allowed the company to increase its reserves in place by more than 500 million tonnes of oil equivalent (mtoe). The company is continuing its investigations at this block, with the construction of new exploratory wells planned for 2019, as well as 3D seismic and the processing and interpretation of data obtained.

Proactive seismic investigations are ongoing at the company’s other offshore projects. 3D seismic works have been completed at the Severo-Zapadny licence block, offshore in the Pechora Sea, as well as offshore 2D seismic investigations at the Severo-Vrangelevsky block, located on the continental shelves of the East Siberian Sea and the Chuchki Sea. 3D seismic works with sea-bottom stations have been undertaken to investigate new horizons at the Prirazlomnoye field, and processing of data from the Dolginskoye field is coming to a close. Decisions on further project development will be taken following interpretation of the data obtained.

The company’s offshore portfolio was further enhanced in 2018 with the addition of the Yuzhno-Obsky licence block in the waters of the Gulf of Ob and the Kara Sea. Reserves in place here are estimated at more than 400 million tonnes of oil.

In the light of Gazprom Neft’s opportunities and its strategic objectives, the company’s geological prospecting programme has been updated to 2021. Its subsequent development will ensure the sustainable development of Gazprom Neft’s offshore assets and consolidate the company’s leading position in offshore operations in the Russian Federation.
