01 — highlander
Developed as a tie back to the Tartan field, Highlander was a 3 well development producing c. 2200 bbls/d prior to shut in in 2020 when the host was decommissioned.
With a STOIIP of c. 180MM bbls, the initial development reservoir is in the Lower Cretaceous Scapa formation, with a new reservoir discovered with an in fill well in the Upper Jurassic Piper formation. The Jurassic reservoir in particular has a very low recovery factor prior to shut in.
03 — galley
Developed as a tie back to the Northern Producer FPSO and later rerouted to Tartan, Galley was producing c. 2000 boe/d prior to shut in in 2020 when the host was decommissioned.
With a STOIIP of c. 114MM bbls, the source reservoir is primarily the Upper Jurassic Galley sands with an overlying Palaeocene accumulation.
05 — petronella
Developed as a tie back to the Tartan field, Petronella was a single well development producing c. 1200 bbls/d prior to shut in.
With a STOIIP of c. 75MM bbls, the initial development reservoir was in the Upper Jurassic Piper formation. The acreage contains multiple additional potential targets.
