Situated in the Southern North Sea, IOG has a 50% working interest in the Blythe Hub which contains two proven gas discoveries which we intend to co-develop as a production hub. The remaining 50% interest is held by CalEnergy Resources Limited.

Field 2P
Blythe 21


The Blythe Field was discovered in 1966 by well 48/22-1, drilled by Burmah and is a good quality Rotliegend reservoir. It was subsequently appraised by wells 48/22-2, 48/23-3 and 48/23-4 drilled by Arco between 1987 and 1990 which tested up to 15 MMscfd.  


Blythe will be developed using a single development well and an unmanned platform.

The Field Development Plan submitted to the OGA has been optimised in 2019 to reflect a two phase development, with Phase 1 comprising the Blythe, Elgood and Southwark Fields and Phase 2 comprising the Nailsworth, Elland and Goddard fields.

FID was declared in October 2019 and Blythe first gas is planned for Q4 2021 following Southwark first gas in Q3 2021.
