The Abbeydale discovery, (previously known as Aberdonia) was proven by well 53/1a-13 drilled by Mobil in 1996. The Abbeydale licence, P2442, was awarded to IOG at 100% working interest in May 2018 in the 30th Licensing Round. IOG committed to reprocess 150 sq. km of 3D seismic and undertake reservoir modelling studies with a drill or drop well commitment within 4 years of licence award – May 2022.

Management estimates of the proven resources are as follows: -

On Structure:

GIIP (Bcf) P90 P50 P10
Abbeydale 8 14 34
Resources (Bcf) P90 P50 P10
Abbeydale 5 11 29

Abbeydale lies 48 km East of Bacton in 25m water depth, to the south of the Leman Field (Shell/Perenco) and the decommissioned Camelot area and approximately 30 km south of the IOG owned Southwark discovery, part of IOG’s Vulcan Satellites Hub.  IOG UK Limited, a fully owned subsidiary of IOG, is Operator of Southwark with 100% working interest.

IOG expects the current evaluation of gas resources to increase following improved seismic imaging via reprocessing.  IOG therefore has looked at a notional development case of 22 BCF.  The current plan for Abbeydale is to drill a single development well by a jack-up unit tied back via an unmanned, minimal facility, well head platform structure to the recommissioned Thames pipeline at Southwark.
