The oil, gas and condensate field lies in the Russian sector of the Caspian Sea, just 40 km from the V. Filanovski field
The field is named in honor of Yuri Sergeyevich Korchagin (1932-2000), the former Secretary of the LUKOIL 's board of directors .
In 1999, LUKOIL started exploratory drilling at the field using the Astra jack-up rig.
Y. Korchagin field was discovered in 2000 and became the 1st field put on stream by LUKOIL in the Caspian sea.
Commercial production at Korchagin field began in 2010.
At the end of 2016, the cumulative production of the field reached 7 million tons of oil.
Owned and operated by Lukoil, the field is developed in 2 phases:
- Phase 1 infrastructure comprises an ice-resistant fixed platform with drilling facilities, a living quarters platform, and an offshore transshipment facility which was used to ship all crude oil output prior to the infrastructure launch at the V. Filanovsky field
- Phase 2 construction comprises a wellhead platform, commissioned in 2018
All facilities for LUKOIL’s offshore fields in the Caspian Sea were built by Russian shipyards.
Produced oil is transported to the floating storage unit 58 km away via a 300 mm subsea pipeline.
The floating storage unit, built by Keppel Corporation at the shipyard in Baku, is moored to a single-buoy mooring.
In 2020, LUKOIL:
-
Constructed the 6 th well at riser block platform at the Korchagin field
- The length of the borehole of this horizontally directed producing well with MultiNode intelligent completion system, used for the 1st time at Caspian projects, was 5 164.79 m
- The drilling was performed from jack-up floating rig Mercury
-
The well's daily target production rate of 348 metric tons allowed to stabilize the field's production
The oil produced at the field is supplied onshore to Makhachkala by shuttle tankers.
At Makhachkala, the oil is fed into the Makhachkala Novorossiysk pipeline, which is jointly operated by SOCAR and Transneft.
