Gazprom Neft increases reserves estimates at Eastern Siberia’s Chonsky group

Gazprom Neft is one of the world’s top-10 public companies by proven liquid hydrocarbon reserves, and a global leader in the rapidity of its reserves replacement

Gazprom Neft increases reserves estimates at Eastern Siberia’s Chonsky group

Irkutsk, December 17 - Neftegaz.RU. Russia’s State Reserves Commission has confirmed a 2-fold increase in reserves at the Ignyalinsky block, forming part of the Chonsky group of fields, with recoverable reserves on this project increasing 35% to 290 million tonnes.

Gazprom Neft specialists have updated the seismic model for the Ignyalinskoye field in the Irkutsk Oblast, having acquired further evidence of this block’s structure and resource potential.

Updated data on recoverable reserves at this asset have now been included in the State Reserves Register, doubling recoverable reserves, which now stand at 151 million tonnes of oil.

Yuri Masalkin, Director for Geological Exploration & Resource-Base Development of Gazprom Neft, said:
  • Modern geological prospecting technologies, Big Data and AI are helping us both in prospecting for oil and in creating optimum algorithms for developing reserves
  • Creating a digital model of the Ignyalinskoye block has made it possible to form a detailed picture of the block’s geological features, as well as this asset’s production potential
  • The data we have collected will help us put in place the optimum scenario for developing the Chonsky group of fields
  • We intend to start implementing this by 2028
Work on developing the seismic model has been ongoing for 4 years.
This project has involved drilling 9 prospecting and production wells and reinterpreting seismic and electronic prospecting data, as well as adopting a new geological field concept, with the information obtained analysed against data from previously constructed 3D models of this asset.

Gazprom Neft’s Chonsky project involves developing the Ignyalinsky, Tympuchikansky and Vakunaysky licence blocks, located on the border between the Irkutsk Region and Yakutia.

The Chonsky-field licence blocks lie some 100 km away from the Eastern Siberia—Pacific Ocean (ESPO) oil pipeline.
The fields included in the Chonsky project have total booked reserves of over one billion tonnes of oil, and some 300 billion m3 of natural gas.
