Yuri Korchagin field
Encyclopedia
The Yuri Korchagin field is an offshore oil field in the Russia
n sector of the North Caspian Sea
. The field is located 180 kilometres (111.8 mi) from Astrakhan
and 240 kilometres (149.1 mi) from Makhachkala
at a sea depth of 11–13 m (36.1–42.7 ). 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.
jack-up rig. 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 570 Moilbbl of 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.
The main production facility is a fixed offshore ice-resistant platform IRP-1. It is 95.5 by with weigh of 25,655 tonne erupting 86.6 metres (284.1 ft) above sea level. The platform was built at the Astrakhansky Korabel shipyard in Astrakhan. The technological complex for LSP-1 was constructed by Stroytransgaz
. The platform was towed to the field assembled in 2009. The IRP-2 platform is used for accommodation of the personnel. It is 41.5 by with weight of 1,340 tonnes. It is 38 by above sea level. The platform was constructed at Lukoil-Kaliningradmorneft factory and assembled at the Astrakhansky Korabel shipyard. Marine warranty services for the transportation and installation of platforms were provided by Crane Marine Contractor Limited and Noble Denton. Offshore installation works were done by J. Ray McDermott
. IRP-1 and IRP-2 are connected by a 74.2 metres (243.4 ft) bridge. The offshore complex is supplied by power produced by using extracted gas.
Produced oil is transported to the floating storage unit 58 kilometres (36 mi) away via a 300 millimetres (11.8 in) subsea pipeline. The floating storage unit, built by Keppel Corporation
at the shipyard in Baku
, is moored to a single-buoy mooring. Oil transported by shuttle tankers to Makhachkala where it fed to the Transneft
's pipeline system.

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.The main production facility is a fixed offshore ice-resistant platform IRP-1.
