Gazprom Neft has commissioned oil production infrastructure at its Pestsovoye and En-Yakhinskoye fields in the Yamalo-Nenets Autonomous Okrug. Production volumes here expected to exceed 6.3 million tonnes of oil equivalent (mtoe) as early as next year. Oil-rim deposits at these two fields from part of the company’s new oil production centre in the Arctic.
A central gathering plant has been commissioned at the Pestsovoye field. This high-tech complex, which will also include a compressor station and gas-treatment unit, will allow all types of crude and feedstocks — oil, gas and condensate — to be processed and shipped.
Gazprom Neft subsidiary Gazpromneft-Zapolyarye is developing oil-rim deposits at the Pestsovoye and En-Yakhinskoye fields under long-term risk-operatorship agreements held by license owner Gazprom Dobycha Urengoy LLC. Gazprom Neft is expecting to produce 2.8 million tonnes of liquid hydrocarbons and 4.3 cubic metres of gas at these fields in 2022. The infrastructure being put in place will allow Gazprom Neft to develop multicomponent deposits — containing oil, gas and condensate — effectively. The possibility of producing hydrocarbons at Achimovsky deposits at the Pestsovoye field will also be considered, going forward.
This project has involved innovative solutions, including, specifically, aerial monitoring of construction works and mobile modular oil production and treatment systems. These ready-to-use units have been installed at the field from readymade modules, bringing field development forward by two years. High-tech multilateral wells — with horizontal shafts running to more than two kilometres — have been drilled to produce oil and gas from narrow oil rims. The complexity of these wells’ construction makes them unique to Russia’s oil and gas industry.
“The oil-rim deposits at the Pestsovoye and En-Yakhinskoye fields form part of a new oil and gas cluster being developed by Gazprom Neft in the Yamalo-Nenets Autonomous Okrug’s Nadym-Pur-Tazovsky district. Additional reserves being brought into development as part of this new cluster over the next five years could see production volumes doubling against original plans next year. While oil-rim deposits are complex, requiring the use of cutting-edge technologies, they already account for about 20% of our annual production volumes — and this figure is only going to grow, going forward.”
Vadim Yakovlev Deputy CEO for Upstream and Deputy Chairman of the Management Board, Gazprom Neft
“Expanding infrastructure will allow us to reach significant oil production volumes at the En-Yakhinskoye and Pestsovoye fields as early as next year. Oil-rim deposits are deemed hard-to-recover reserves — distinguished by narrow oil-bearing strata, and also containing gas and water. This is a unique multicomponent asset, from which we will be producing not just oil but also gas and condensate. Innovative approaches in construction and drilling, together with block-modular and digital solutions, have allowed us to find the keys to these complex reserves quickly and start developing them commercially.”
