Saturn Banks production restart

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 operational update.

Saturn Banks Operations

-     Production has been restarted from both Blythe and Elgood into the Saturn
Banks Pipeline System ("SBPS") as planned after completion of shutdown works

-     Gas sales are expected to recommence today following full repressurisation
of the line

-     Final connection, dewatering and backgassing of the SBPS outer section to
Southwark have all been successfully completed, bringing it up to pressure ahead
of Southwark first gas

-     Additional modifications were also completed in parallel at Saturn Banks
Reception Facilities onshore at Bacton terminal to de-risk potential for future
shutdowns

Southwark Drilling

-     A2 hydraulic stimulation operations are underway and expected to continue
into December

-     A2 first gas remains expected around year end, subject to stimulation
progress and operational risks to final hook-up and commissioning

-     A1 well to be completed after A2 first gas, as previously confirmed

Rupert Newall, CEO of IOG, commented:

"I am very pleased to confirm that Saturn Banks Phase 1 production has been
safely restarted after successful completion of shutdown activities. This was
one of our top priorities as the new leadership team and the real commitment
shown across the team to meet this key objective bodes well for our continuing
work to address recent operational challenges.

In parallel, with hydraulic stimulation underway at the A2 well, we are equally
focused on bringing Southwark onstream in a safe and timely manner, the next of
a series of key objectives we have set to deliver the value in our portfolio. I
look forward to keeping investors informed as these materialise.
