UK Central North Sea


RockRose Energy currently holds non-operated interests in five UK Central North Sea oil and gas fields, consisting of both mature and recently onstream assets. These include the Arran, Nelson & Howe, and Blake & Ross fields.


Arran Field

The Arran gas condensate field is operated by Shell as a 60-kilometre subsea tie-back to the Shearwater platform. Hydrocarbons are processed on and then exported from the platform, with gas joining the SEGAL system and condensate the Forties pipeline system. Discovered in 1985, Arran has come onstream in 2021

Equity: 30.43%

Status: Onstream

Location: Arran is located 240 kilometres east of Aberdeen, close to the UK/Norway median line, in a water depth of 85 metres.

Potential: Arran is estimated to have long-term potential in terms of recoverable gas reserves. RockRose Energy invested $120 million in the development of the Arran field in 2018, with first gas produced in September 2021.

Latest Production Results: ~6,500 boepd / 4.6 Mmboe net to RockRose in 2022

 Nelson & Howe Fields

The Nelson & Howe oil fields are operated by Shell. Developed with a fixed platform, Nelson produces light oil from a reservoir at a depth of approximately 2,200 meters. The smaller Howe field was brought onstream as a single-well subsea tie-back to the Nelson platform. The oil from the platform is transported by pipeline to the Forties field and then to shore via the Forties pipeline system.

Equity: 7.48% (Nelson); 20.00% (Howe)

Status: Onstream

Location: Nelson is located approximately 200 kilometres northeast of Aberdeen in a water depth of 88 metres. Howe is located 14 kilometres east of the Nelson field, in a water depth of around 90 metres.

Potential: The Nelson and Howe fields began production in 1994 and 2004, respectively. RockRose Energy acquired interests in the fields in December 2017, in order to support the life cycle extension of a high-quality reservoir.

Blake & Ross Field

The Blake & Ross oil fields, operated by Repsol Sinopec, produce into the Bleo-Holm Floating Production, Storage & Offloading (FPSO) vessel via subsea infrastructure. The Ross field is currently offline, while oil from the Blake field is produced via a subsea manifold and dual flowlines to the Ross FPSO. Blake is divided into two areas – the Blake Channel and the Blake Flank. The two were developed separately, with 6 production wells and 2 water injection wells drilled into the Blake Channel, and 2 production wells drilled into the Blake Flank.

Equity: 30.82%

Status: Onstream

Location: Blake is located around 120 kilometres northeast of Aberdeen in a water depth of approximately 110 meters.

Potential: RockRose Energy’s 2017 acquisition of Blake & Ross is another initiative aimed at prolonging the life cycle of mature oil & gas fields to ensure they reach full production potential. The Blake field has been producing oil since 2001, while Ross began production in 1998.
