The boundaries of the Ignyalinsky block were expanded through what is known as the “cut-in mechanism” (involving the addition of a piece of adjacent land comprising open acreage (land as yet unallocated under the State Subsoil Reserve Fund), with this asset now increasing to 2,200 km2 in size.
The Chona project includes the Ignyalinsky, Tympuchikansky and Vakunaysky license blocks, located on the border between the Irkutsk Oblast and the Sakha Republic (Yakutia). These assets are located 100 km from the East-Siberia Pacific Ocean (ESPO) pipeline. Total IRIP at fields on the Chona project stand at more than 1 billion tonnes of oil, and about 300 billion cu m (bcm) of gas.
“The Chona group of fields comprise Gazprom Neft’s anchor asset in Eastern Siberia. They are notable for their remoteness from major logistics centres and their complex reservoir structures, but also for their uniquely high production potential. We have gained a detailed understanding of the geological features of these blocks in recent years, and have put in place a strategy for developing them, confirming the commercial prospects for this project. All of which means we will shortly be able to being pilot development of the Chona fields, initial reserves in place of which stand at more than one billion tonnes of oil", said Yuri Masalkin, Director for Geological Prospecting & Resource Base Development, Gazprom Neft.
