Yuri Korchagin field
From Kazakhstan Encyclopedia
Template:Infobox oil field The Yuri Korchagin field is an offshore oil field in the Russian sector of the North Caspian Sea. The field is located Template:Convert from Astrakhan and Template:Convert from Makhachkala at a sea depth of Template:Convert. 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.[1][2]
Overview
Lukoil started geological survey of North Caspian Sea in 1995. Exploratory drilling started in 1999 by using Astra semi-submersible jack-up rig.[2] 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 Template:Convert 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.[2][1][3]
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.[1]
The main production facility is a fixed offshore ice-resistant platform IRP-1. It is Template:Convert with weigh of 25,655 tonne erupting Template:Convert above sea level. The platform was built at the Astrakhansky Korabel shipyard in Astrakhan.[2][1][4] The technological complex for LSP-1 was constructed by Stroytransgaz.[5] The platform was towed to the field assembled in 2009. The IRP-2 platform is used for accommodation of the personnel. It is Template:Convert with weight of 1,340 tonnes. It is Template:Convert above sea level. The platform was constructed at Lukoil-Kaliningradmorneft factory and assembled at the Astrakhansky Korabel shipyard.[1] Marine warranty services for the transportation and installation of platforms were provided by Crane Marine Contractor Limited and Noble Denton.[6] Offshore installation works were done by J. Ray McDermott.[7] IRP-1 and IRP-2 are connected by a Template:Convert bridge. The offshore complex is supplied by power produced by using extracted gas.[2][1]
Produced oil is transported to the floating storage unit Template:Convert away via a Template:Convert subsea pipeline. The floating storage unit, built by Keppel Corporation at the shipyard in Baku, is moored to a single-buoy mooring.[1][4] Oil transported by shuttle tankers to Makhachkala where it fed to the Transneft's pipeline system.[2][1][3]
