LONDON  IOG has issued an update on its Saturn Banks gas development in the U.K. southern North Sea.

Production has ramped up from 30 MMcf/d at the start of this month to 54 MMcf/d. IOG is targeting 45 MMcf/d to 60 MMcf/d for the second half of 2022.

The Seven Borealis has laid the 6-km, 24-inch pipeline extension between the Saturn Banks Pipeline System and the Southwark facilities, and drilling of the Southwark East well is advancing. The Noble Hans Deul jackup rig will then drill the Southwark West well, with both wells due to be completed by the fourth quarter.

Southwark should deliver first gas during this period.

Onshore, there have been improvements to liquids management and reliability at the gas reception terminal in Bacton, and the remaining restriction to gas flow should end over the next few weeks.

In parallel, work is underway offshore to improve the Blythe platform's electrical stability and reduce the risk of emergency shutdowns. Permanent chemical injection modifications should allow full remote restart capabilities to be reinstated by early fourth-quarter 2022.

After Southwark, Noble Hans Deul is contracted to drill the Goddard and Kelham North/Central appraisal wells. The Goddard well is intended to define the southeast extent of the main discovery and de-risk its two flank structures to support planning for location of the platform and well numbers.

The main aim of the Kelham North/Central appraisal well is to prove up both accumulations as part of a potential three-field southern hub gas production cluster, including the Abbeydale discovery on the same (P2442) license.
