Operational Update

IOG plc ("IOG", or "the Company"), (AIM: IOG.L) provides a further update on drilling and production operations at the Blythe field.

·      The Blythe H2 well control event encountered from the Hauptdolomit has been successfully isolated without the requirement to sidetrack the well,

·      The 7" liner was run and cemented to isolate the kick/loss zone.  

·      The 6" hole section commenced from the 7" liner shoe at 9,860ft measured depth ("MD") as per revised plan.

·      The 6" hole section continued to the Rotliegendes reservoir section which was encountered on Sunday 14^th May at a depth of 11,660 ft MD which was within expectations. Drilling continues to an expected total depth of c.13,000 ft MD.

·      First gas from the Blythe H2 well is still expected to commence by the end of Q2

·      Production from the Blythe H2 well will be initially ramped up to safely and efficiently manage the production of the resident pipeline fluids into Bacton, then expected to build up to 30-40 mmscf/d rate post ramp up

·      The Blythe H1 well is initially planned to be shut in once the H2 well is fully onstream to reduce water production into the pipeline however the H1 well will remain available for production

Rupert Newall, CEO, commented:

"The IOG, Petrofac and Shelf teams have worked extremely hard to isolate the kick/loss zone safely and successfully on Blythe H2. I am pleased to say that the 6" hole section has so far been drilled efficiently and it is encouraging that the top reservoir has been encountered within expectations. The teams are working tirelessly to ensure the remainder of the well as well as the hook up and commissioning of the new well into the Saturn Banks Pipeline system is delivered as efficiently as possible."
