Intro
Gullfaks A is a large concrete gravity base production platform on the Gullfaks field in the northern North Sea, installed in 1986 and on stream in December that year. It integrates drilling, production, processing, storage and accommodations and serves as a central export hub for oil and gas.
Field
The Gullfaks field, discovered in 1978 in the Tampen area, produces oil with associated gas from Middle Jurassic Brent Group and adjacent Triassic/Jurassic formations. It features three Condeep platforms (A, B, C) and subsea tie-backs to satellite discoveries.
Facilities
Gullfaks A supports numerous production and injection wells drilled through its concrete base and steel topsides. Topside facilities include three-phase separation, crude stabilisation, oil storage cells and interfaces for gas export. Oil is stabilized and routed to offshore loading systems via mooring buoys; rich gas is exported into Statpipe and further to onshore processing at Kårstø. Water injection enhances recovery and utilities include power generation, water handling and flare systems. Accommodation and control rooms support safe, long-term offshore operations. Gullfaks A also receives and processes hydrocarbons from satellite fields such as Gullfaks South, Rimfaks and others tied back via subsea infrastructure.
