Operational Update

IOG plc ("IOG", or "the Company"), (AIM: IOG.L), the Net Zero UK gas and infrastructure operator focused on high return projects, provides a further Phase 1 update.

The Company and its offshore Duty Holder ODE Asset Management (ODEAM) have continued to investigate the previously announced chemical injection fault on the Blythe platform which necessitated the Blythe well to be temporarily shut in. On further inspection, additional process and safety studies and procurement of materials are required before implementing the solution. These workstreams are being pursued as rapidly as possible to expedite safe reopening of the Blythe well. The Company will provide further updates as appropriate.

The fault is a mechanical issue on the Blythe topsides and does not relate to the Blythe reservoir. Moreover, it has not impacted the ability to maintain Elgood production which continues in the meantime.

At Southwark, following a successful exercise to remediate the seabed conditions, development drilling remains expected to resume by mid-April as previously stated. 

Andrew Hockey, CEO of IOG, commented: 

"We are working urgently to resolve this very frustrating platform mechanical issue which has shut in the Blythe well. Importantly, this is not a reservoir related issue and Elgood production continues in the meantime within a very strong gas market. We will release further updates as we clarify the timing of Blythe resumption."

This announcement contains inside information for the purposes of Article 7 of the Market Abuse Regulation (EU) 596/2014 as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 ("MAR"), and is disclosed in accordance with the company's obligations under Article 17 of MAR.
