Mad Dog Phase 2 development details
http://www.offshore-technology.com/projects/mad-dog-phase-2-gulf-of-mexico/The proposed development will comprise an integrated semi-submersible floating production platform that will be moored in 4,440ft of water in the Green Canyon. It will be located in block 780, west of the existing Mad Dog spar. Oil produced from the field will be transported to the Mardi Gras pipelines as per current agreements.
A water-flood project based on BP's LoSal flooding technology has also been planned in order to enhance oil recovery from the field. It will handle 280,000b/d of low-salinity water flooding.
Design of the platform has been inspired from BP-operated Atlantis semi-submersible platform that is able to decrease the weight of the topsides to 25,000t. It will also integrate the topside infrastructure with the jacket structure.
The development plan outlines the drilling of 29 wells, including 17 wet-tree producers and 12 wet-tree injectors from five drill centres located in blocks 825 and 870. Front-end engineering and design (FEED) work on the project started in the third quarter of 2014.
