Gazprom Neft has begun developing the northern section of its Novoportovskoye field — one of the company’s key oil production centres in the Arctic. Implementing this project should see the company’s Arctic asset reach peak production, at eight million tonnes of oil per year, by 2021.
Recoverable reserves in the northern section stand at more than 27.8 million tonnes of oil, and 28.5 cubic metres of gas. The company’s investment in developing this field is expected to reach RUB86 billion.
The key challenge in developing this field lies in its remoteness from basic field infrastructure: to which end, the company is now completing its construction of the “Sever” digital substation, to ensure an energy supply to the new field.
Ten well pads — all of them comprising high-tech wells — will be installed to facilitate oil production in the northern part of the Novoportovskoye field. First oil has already been produced at the first well, which runs to a total length of 3,395 metres, with a
A proven technology in Arctic fields — Premium Port hydraulic fracturing (fracking) — is being used to enhance oil recovery,** having been initially tested in developing the Novoportovskoye field in 2016. Premium Port fracking promotes safety in oil production by making it possible to selectively close frack ports in the event of water or gas ingress while drilling.
“Novy Port is the flagship in Gazprom Neft’s development of the Arctic. The ‘Arctic Gates’ terminal was launched here in 2016, making it possible to start shipping oil through the Northern Sea Route, improving the viability of the Arctic project. A new and ambitious task is now being addressed in these northern latitudes — managing oil production in the northern part of an asset some considerable distance from key Novoportovskoye field infrastructure. This is a major step forward in implementing this project, and one that demands using cutting-edge technologies and finding new solutions.”Sergey Doktor Head of the Oil and Gas Production Directorate, Gazprom Neft
“Developing the northern part of the Novoportovskoye field will give serious impetus to developing this asset, making it possible to maintain the required hydrocarbon production volumes in the long term. Our team has wide-ranging experience in addressing challenging tasks in the Russian Far North, having, over the years, developed technologies and business cases that mean Arctic fields can now be developed efficiently and safely.”Alexey Ovechkin Director General, Gazpromneft-Yamal
The development of the northern part of the Novoportovskoye field was initiated in 2016 during the expansion of existing field-production infrastructure, with a view to developing new oil deposits within the existing license block.
* Premium Port hydraulic fracturing (fracking) is a technology involving full-bore sliding sleeves. This equipment enhances hydrocarbon recovery by exponentially increasing the fracture contact area, controlling the fracture initiation site, and its extent and conductivity.
The 2×40-MVA transformer 110/10Kw “Sever” digital substation has sufficient capacity to ensure uninterrupted electricity supplies to a population of 10,000 people. This unique project is the first of its kind to be implemented in oil and gas infrastructure in the Arctic, and forms part of a national project from the Ministry of Energy of the Russian Federation, “Commissioning Digital Electricity Stations and Substations at New and Reconstructed Energy Facilities”. The facility is expected to be commissioned at the Novoportovskoye field in late 2020.
The Novoportovskoye field is one of the most important oil and gas-condensate fields on the Yamal Peninsula. It is located within the Arctic Circle, some distance from pipeline transportation infrastructure. Year-round shipments of hydrocarbons from the Novoportovskoye field are undertaken through the Arctic Gates transhipment terminal in the Gulf of Ob. Recoverable C1+C2 reserves at the Novoportovskoye field stand at more than 250 million tonnes of oil and condensate, and more than 320 cubic metres of gas. Novy Port-blend crude is categorised as “light”, with low sulphur content (of about 0.1 percent).
