Gazprom Neft has begun its full-scale improvement of a serious hydrocarbon cluster (with whole potential sources estimated at 650 million tonnes of oil) overlaying license blocks within the Khanty-Mansi Autonomous Okrug and the Tyumen Oblast. One million tonnes of liquid hydrocarbons have been produced on the flagship asset on this undertaking, the Alexander Zhagrin subject, Yugra, in its first yr below improvement. Peak manufacturing at this subject is anticipated to be reached in 2024, at 6.5 million tonnes of oil per yr.
In January 2018, the sphere was named in honour of Alexander Zhagrin, the previous Head of the corporate’s Oil and Gas Production Directorate, who handed away in December 2017.
This new manufacturing cluster consists of 5 license blocks — the Zapadno-Zimny, Severo-Vaysky, Karabashsky-84 and the Srednevaysky blocks, all positioned within the Kondinsky district of the Khanty-Mansi Autonomous Okrug-Yugra, and the Yuzhno-Zimny block within the Uvatsky district of the Tyumen Oblast. These blocks collectively cowl 5,000 sq. kilometres in whole, with reserves initially in place (RIIP) estimated at 650 million tonnes.
The key asset — and the nexus of this new undertaking — is the Alexander Zhagrin subject. Reserves initially in place listed below are estimated at 111 million tonnes of oil. Well pads, oil-gathering traces, a separation unit, an preliminary vitality complicated, energy provide traces and road-transport community amenities have, already, been put in at this subject, initially found in 2017. An oil processing facility is anticipated to be commissioned in 2022. Construction of the sphere’s (already partially functioning) oil transportation infrastructure is anticipated to be accomplished by the top of 2020. This will join future oil remedy amenities with the Demyanskoye crude oil supply and acceptance level, from the place hydrocarbons will subsequently feed into the Transneft trunk pipeline system.
Fifty-four manufacturing wells have been drilled on the Alexander Zhagrin subject thus far. That quantity is anticipated to achieve 920 by 2028, with 70% of those being high-tech horizontal wells.
The Severo-Vayskoye and Srednevayskoye fields have been found inside this new cluster, on the respectively named license blocks. The whole useful resource potential of those two fields stands at about 81 million tonnes of liquid hydrocarbons. Initial estimates recommend whole RIIP on the Yuzhno-Zimny and Karabashsky blocks might exceed 180 million tonnes of oil, with reserves on the Zapadno-Zimny block estimated at 388 million tonnes of oil.
Geological prospecting is anticipated to be full by 2027 on the Severo-Vaysky, Srednevaysky and Zapadno-Zimny blocks, and by 2029 on the Yuzhno-Zimny and Karabashsky-84 blocks. The outcomes of prospecting actions will make it attainable to place a improvement programme in place for every of the blocks in Gazprom Neft’s new oil manufacturing cluster in Western Siberia. Development of those belongings shall be undertaken by Gazpromneft-Khantos.
