2.3. Development Options
Prior to RDUK becoming operator of the Breagh field in mid 2009, the previous operator,
Sterling Resources (UK) Limited, undertook a preliminary evaluation of export routes from
the Breagh field. The options under consideration at that time included pipeline routes to
the following locations:
• ConocoPhillips (CMS, Murdoch), approximately 120 km;
• Perenco (Tyne/Trent), approximately 80 km;
• BP Cleeton, approximately 60 km;
• Centrica (Rough), approximately 85 km; and
• Teesside Gas Processing Plant (TGPP), approximately 100 km offshore section and 10
km onshore to the existing facility.
These export options are schematically represented in Figure 2-3 below.
