North Sea Transition Authority (“NSTA”)

Formerly Oil & Gas Authority (“OGA”)

The NSTA is the organisation in the UK that regulates the exploration and development of the UK’s offshore and onshore oil and gas resources and offshore carbon storage, offshore gas storage and offshore gas uploading activities.

In November 2021 the OGA announced the MNSH Exploration Area Plan to integrate exploration, development, production, and decommissioning to ensure operations maximise economic recovery with the optimum use of infrastructure to extend asset life.

“The Southern North Sea (‘SNS’) portion of the Mid-North Sea High (‘MNSH’) area has been identified for an exploration-focused area plan because of the

significant hydrocarbon volume potential & recent exploration success

in close proximity to infrastructure, with new modern seismic data now becoming available.”
