Asset Description and Overview

The Elgin-Franklin development is located in the Central Graben Area. The installation consists of three separate platforms, two of which are connected by a 90 m bridge: two wellhead platforms which house the wells, one each for the Elgin and Franklin reservoirs, and the process, utilities and quarters (PUQ) platform, which is the central processing platform

The Franklin wellhead platform (WHP) has nine well slots (seven wells on the Franklin Field and two extended reach wells on West Franklin). It is not normally manned but has a helideck and shelter for up to 20 people.

The Elgin wellhead platform has 12 well slots (11 wells on Elgin and one extended reach well on Glenelg). The platforms are linked to the PUQ by flowlines and were installed in 1999.

The Produced oil is transported through the Forties pipeline system to the terminal in Grangemouth while produced gas is transported through the SEAL Pipeline to Bacton
