West of Shetland

RockRose Energy’s operations in the West of Shetland consist of non-operated interests in the Greater Laggan Area, following Viaro Energy’s successful acquisition of the SSE exploration and production gas assets in 2021.

Greater Laggan Area (GLA)

RockRose Energy has interests in the GLA, the first gas development in the West of Shetland, UK area, operated by Total Energies. The GLA comprises 4 producing gas condensate fields (Laggan, Tormore, Edradour, and Glenlivet), two surrounding exploration licences (Benriach and Cardhu), and the Shetland Gas Plant, with offshore and onshore pipelines. Production from Laggan and Tormore began in 2016, while Edradour and Glenlivet were brought onstream in 2017.

All 4 fields are developed as a subsea tie-back to the TEPUK-operated Shetland Gas Plant through two 18-inch production flowlines. Gas is transported onwards into the SIRGE system and subsequently into the NSM-operated FUKA system, delivering gas and natural gas liquids to the UK mainland at St. Fergus. The condensate is separated at the SGP and delivered to the neighbouring Sullom Voe terminal.

Equity: 20% (Laggan, Tormore, Edradour, Glenlivet, Cardhu, and Shetland Gas Plant); 25% (Benriach)

Status: Onstream (Laggan, Tormore, Edradour, and Glenlivet); Pre-development appraisal (Benriach and Cardhu)

Location: The GLA gas fields are located 125 kilometres northwest of the Shetland Islands on the UKCS, in a water depth between approximately 300 metres and 625 metres.

Potential: Viaro Energy acquired interests in the GLA’s producing fields and exploration licences in 2021. The GLA’s fields have begun coming onstream since 2016 and are estimated to have long-term production potential.
