Development
Nailsworth lies 19km north of the Southwark field. Nailsworth is expected to be developed as part of the Saturn Banks Project – Phase 2, with up to three hydraulically stimulated development wells drilled by a jack-up rig through a suitable Normally Unmanned Installation platform, to be linked to the main Saturn Banks Pipeline export route via a new pipeline connection.
