IOG plc reported stable oil and gas production from its operations at the Saturn Banks infrastructure in the UK Southern North Sea.
PHASE I
The company is in Phase I of the project, which started production in March 2022, to commercialise the Blythe, Elgood and Southwark gas fields.
BLYTHE & ELGOOD
IOG said that stable gas production from Elgood and Blythe was currently established in the 55-65 mmscf/d range on a gross basis.
Since first gas from both wells in mid-March to end of April, overall average aggregate gas production was 37 mmscf/d, with average uptime of 68% at Elgood and 33% at Blythe.
The company added that this primarily reflected the chemical injection fault outage before the Blythe well was reopened in mid-April, among other shorter temporary outages.
Average aggregate condensate arrivals into Bacton have been in the 800-1,000 bbl/d range since first liquids flowed onshore on 7 April.
SOUTHWARK
Drilling of the two development wells, Southwark east and west, is scheduled to continue into Q4 2022, with first gas later the same quarter.
IOG said that, following seabed remediation, the Southwark east well was in good condition with no further rig stability issues, and allowing planned drilling to continue.
Southwark accounts for the majority of 2022 net capital expenditure currently expected to be £70-85 million.
This figure incorporates projected Goddard, Kelham North/Central and Nailsworth expenditure.
PHASE II
Phase II of the Saturn Banks project involves the Nailsworth, Goddard and Elland gas discoveries.
IOG plans to drill the appraisal wells at Goddard and Kelham North/Central in direct continuation from the Southwark east and west development wells.
Geophysical site surveys for both appraisal wells were completed in March, with the Nailsworth area also incorporated in the same campaign.
Geotechnical surveys are planned for later this quarter.
The basis of designs for the two appraisal wells are complete and detailed well planning, contracting and long-lead procurement is underway in preparation to execute the appraisal wells in Q4 2022.
