Ithaca set for stake in Vorlich in North Sea

Offshore staff

CALGARY, Canada – Ithaca Energy has agreed to acquire a 20% interest from Total E&P UK in license P363 (block 30/1c) in the UK central North Sea.

BP operates the license which contains an estimated 80-90% of the Vorlich discovery, 10 km (6.2 mi) north of the Ithaca-operated Greater Stella Area hub. 

Vorlich was discovered and appraised in 2014 with exploration well 30/1f-13A, Z, and 13Z. The well encountered hydrocarbons in a Palaeocene sandstone reservoir in block 30/1c: a subsequent side track into block 30/1f confirmed a westerly extension of the find.

Ithaca assesses proven and probable reserves at 20-30 MMboe.

The focus of this year’s program for the license is the preparation and submission for approval by year-end of a field development plan.

As for the GSA development, the main issue remains completion of the modifications to the semisubmersible platform FPF-1, managed by Petrofac at the Remotowa shipyard in Poland.

Sail-away was planned for end-1Q, but this is set to be delayed by a further six to 12 weeks owing to slippage in completion of certain commissioning milestones and the requirement for some marine system re-work to ensure the vessel meets sail-away certification standards.

The company now anticipates start-up of the Stella field this summer.

All required subsea infrastructure has been installed prior to arrival of the platform and all five Stella development wells have been drilled and tested.

Elsewhere in the central UK sector, Ithaca expects restricted production rates from the Shell-operated Pierce field during the first half of this year, due to the need to complete remedial works on the subsea gas injection flowline.
