Access to Infrastructure

Serica became operator of the Bruce field in November 2018 and is working to extend field life, increase the utilisation of the facilities and maximise economic recovery from the area as a whole. The extensive infrastructure associated with the Bruce field offers significant capacity for third party tieback opportunities. Serica welcomes enquiries from potential shippers.

Overview

The Bruce complex is located in blocks 9/9a, 9/8a and 9/9b. It lies 340km to the northeast of Aberdeen, Scotland in the UK Sector of the Northern North Sea.

The Bruce complex consists of three bridge-linked platforms:

  • A Production Utilities Quarters Platform with quarters for crew (max. 168 persons);
  • A Drilling Platform; and
  • A Compression/Reception Platform which hosts reception and compression facilities.

The subsea Keith and Rhum fields are both tied back to the Bruce complex where they are transported and processed for export. Gas is exported via the Frigg pipeline to the St Fergus terminal and liquids are exported via the Forties Pipeline System.

Capacity Projection

The current capacity projection for the Bruce platform over the next 5 years is shown in the table below:

Description Unit Max Capacity Projected ullage
(% of maximum capacity)
2019 2020 2021 2022 2023
Oil Handling Capacity BPD 70,000
Gas Handling Capacity MMscfd 440
Produced Water Capacity BPD 20,000
Water Injection Capacity BPD 35,000

Available Capacities key:

>25%
5% to 25%
<5%

Note: Capacities for gas processing based on current export pipeline operating pressure which is subject to change and may reduce overall throughput

Outline details of primary separation processing facilities

The Bruce facilities have three primary first stages of separation:

  • The CR Slugcatcher processes gas from the Western Area Development and Keith subsea tie-backs. The CR Slugcatcher is a horizontal 3-phase separator
  • HP Separators process gas from both the Bruce platform wells and the CR Slugcatcher. There are two HP Separators which are vertical 3-phase separators (currently operating in 2-phase mode)
  • The Rhum Separator processes gas from the Rhum subsea tieback. The Rhum Separator is a vertical 3-phase separator. Gas is treated immediately after the Rhum Separator for H2S by scavenging

All liquids are routed from these vessels directly to LP Separation. Water is sent on for processing and oil is exported via a 24” pipeline to FPS via the Unity Platform.

Outline details of gas treatment facilities

Bruce has three stages of compression and gas dehydration facilities:

  • LPBC – Low Pressure Booster Compressors
  • MP – Mid Pressure Compression
  • Export – Export Compressors
  • Dehydration occurs between MP and Export compression stages

There are two LPBC, two MP, and two Export Compressors available. Dehydration occurs through a single dehydration column operating a glycol regeneration process. Gas is exported via a 32” pipeline to St Fergus via the Frigg Pipeline system.
