Britannia Gas Field

The 13,000-ft-deep Britannia field is located in U.K. Continental Shelf Blocks 15/29a, 15/30, 16/26, 16/27a, and 16/27b, 130 miles northeast of Aberdeen in approximately 450 ft of water
Britannia is one of the largest natural gas and condensate fields in the North Sea.
The field has two manned platforms, the original Britannia Platform and a smaller Bridge Linked platform added later
The Finlaggan Gas Field is a 2 well tie back to Britannia platform.
Condensate is delivered through the Forties Pipeline System to the oil stabilization and processing plant, Kerse of Kinneil, near the Grangemouth Refinery in Scotland,
Natural gas is transported through a dedicated Britannia Gas Pipeline to the SAGE St Fergus Gas Processing Terminal at St. Fergus, Scotland.
Callanish and Brodgar Oil and Gas Fields have been developed as satellites
The Caledonia Field is a subsea development in UKCS Block 16/26. The Field lies in a water depth of 139 metres, approximately 6km north of the Britannia Platform, which it is tied-back to.

The reservoir contains a retrograde gas/condensate fluid whose composition varies from west to east. The hydrocarbon is richer in the west (condensate/gas ratio of 100 bbl/MMscf) and leaner in the east (condensate/gas ratio of 70 bbl/MMscf).
An oil rim lies along the southern edge of the reservoir. Although the oil is a good-quality, light but waxy, sweet crude, it is relatively immobile. An aquifer lies under the oil rim.
The length of the reservoir has five distinct regions, each of which has an aquifer with different water chemistry.
