[UK] Alma & Galia

Unread post by escveritas »

The Alma and Galia oil fields are situated in blocks 30/25c and 30/24b respectively of the United Kingdom Continental Shelf and operated by EnQuest Heather Limited. These fields are located approximately 282km north-east of Northumberland coast (Seahouses), in water depths of ~77m.

The Alma and Galia fields were developed as a single joint development and came onstream in late 2015. They produce via subsea wells tied-back to the FPSO vessel via one central hub for all fields. Alma has six production wells and one water injector, while Galia produces via one well. The Cessation of Production documentation for the Alma & Galia fields is currently under consideration by the Oil and Gas Authority.

The Decommissioning Programmes explain the principles of the removal activities and are supported by an environmental appraisal report. The Decommissioning Programmes for the pipelines are also supported by a comparative assessment.

The Decommissioning Programmes are:
  • The EnQuest Producer floating production storage and offloading vessel (FPSO) complete with all subsea equipment, including manifolds and wellhead protection structures;
  • All pipelines associated with the Alma field including PL3006, PL3007, PL3008, PLU3009, PL3011, PL3012, and PL3013 and associated jumpers;
  • The Galia installation, a wellhead protection structure; and,
  • All associated pipelines including PL3014, PLU3015, and PL3016
