Development Project - Victory Field
The Victory Project is to develop the Victory subsea gas field as a single well tie-back to the Shetland Gas Plant. This is to be achieved by drilling a new well and installing a pipeline to route hydrocarbons via an existing hot tap tee into the existing Greater Laggan Area (GLA) pipeline system to export via the Shetland Gas Plant. Well control will be provide via an umbilical pipeline route from Edradour manifold location to the Victory Well.
Note: the Victory wellsite is within an Offshore Development Area and as such, is not for entry by trawlers.

Drilling of the Abbey well by the Noble Resilient jack-up drilling rig
Petrogas North Sea Ltd intends to carry out drilling operations using the jack-up drill rig “Noble Resilient” at the Abbey gas field . The work is expected to take around 100 days at the Abbey location. However the actual duration will depend on both operational and weather factors. Whilst at location the vessel will be static and connected to the seabed so is unable to move or maneuver its position.
Petrogas seeks the cooperation of fishermen to refrain from placing static fishing gear within 500m of the Abbey well site location, where the jack-up drill vessel will be working, This is to avoid any entanglement, interference or damage to either the fishing gear or drilling equipment.
From mid January to end February 2025 operations will include fraccing, involving the use of a DP frac support vessel connected to the platform.
