Scarborough gas field is located approximately 270km north-west of Onslow in the Carnarvon Basin in the Northwestern Shelf, offshore Western Australia, in water depths of 900m to 1,500m.

The plan for the development of the Scarborough field includes the drilling of 12 daisy-chained subsea gas wells, tied-back to a semisubmersible platform moored in 900m of water.

A total of seven horizontal and high-angle wells have been drilled at a depth of 2,500m as part of the initial phase of development.

The gas field has been developed using a floating production unit (FPU), comprising of a topside with a production capacity of up to 9t a year installed over the semi-submersible hull.

The natural gas processing unit installed on the topside of the FPU includes gas separation, dehydration and compression along with Mono Ethylene glycol (MEG) regeneration and water handling systems.
