The '''Yuri Korchagin field''' is an offshore oil field in the [[Russia]]n sector of the North [[Caspian Sea]]. The field is located {{convert|180|km}} from [[Astrakhan]] and {{convert|240|km}} from [[Makhachkala]] at a sea depth of {{convert|11|-|13|m}}. The field is owned and operated by Lukoil–Nizhnevolzhskneft, a subsidiary of [[Lukoil]]. The contractor for drilling operations is a Moscow-based company BKE Shelf (Eurasia Drilling Company). The field is named after the former secretary of the company's board of directors.<ref name=korchagin>

==Overview==
Lukoil started geological survey of North Caspian Sea in 1995. Exploratory drilling started in 1999 by using ''Astra'' [[semi-submersible]] jack-up rig.<ref name=lukoil>

</ref> The field was discovered in 2000. Its development started in 2004. The first oil was extracted on 28 April 2010. The gross reserves are estimated to be {{convert|570|Moilbbl}} of [[Tonne of oil equivalent|oil equivalent]]. The expected peak production rate is 2.5 million tonnes of [[crude oil]] and 1.2 billion cubic meters of [[natural gas]] per year.<ref name=lukoil/><ref name=korchagin/><ref name=upstream280410>

==Development==
The development will have 30 wells, including 26 production wells, one gas-injection well and three water-injection wells. As of April 2010, one oil production well and one gas extraction well were operational. By mid 2010, a water injection well was added. The wells have been drilled horizontally and their radial placement enables in their simultaneous drilling. Control of drilling operations on the platform and field have been done since 2009 by Eurasia Drilling Company. A total of R34.4bn ($1.12bn) has been spent on field development between 2004 and 2009.<ref name=korchagin/>

The main production facility is a fixed offshore ice-resistant platform IRP-1. It is {{convert|95.5|by|72.2|m}} with weigh of 25,655 tonne erupting {{convert|86.6|m}} above sea level. The platform was built at the Astrakhansky Korabel shipyard in Astrakhan.<ref name=lukoil/><ref name=korchagin/><ref name=upstream290709>
