IOG has a 50% operated working interest in the Blythe Hub in the Southern North Sea, comprised of two proven gas discoveries, Blythe and Elgood, which we are in the process of developing as a production hub. The remaining 50% interest is held by CalEnergy Resources (UK) Limited (CER).
Please see page 10 of the Annual Report 2022 for a statement of reserves & resources.
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.
Final Investment Decision (FID) on Blythe was declared in October 2019 as part of the Phase 1 FID. The Phase 1 Field Development Plan (FDP) was approved by the UK government in April 2020 and First Gas was achieved in Q1 2022.
