The estimated $300 million project is centred on recycling gas located in the Arab D gas cap in the Dukhan field. It entails processing 800 million cubic feet a day of wet gas to recover 41,000 barrels a day of condensate and 750 tonnes a day of natural gas liquids (NGL), which will be sent by pipelines to Urn Said. The remaining dry gas will be reinjected into the reservoir to maintain pressure.

The project involves the establishment of a gathering system serving 21 production wells and a gas injection network for 14 wells. The gas will be gathered at a new gas recycling plant where the condensate and NGL will be stabilised into product streams. The products will then be transported by pipeline to the existing Fahahil stripping plant, which will be expanded to accommodate the increased supplies. Here, further treatment will take place before being piped to Umm Said.

Fifteen kiornetres of new NGL pipeline will be built, plus a condensate line of 104 kilometres. At Urarn Said, two new 55,000 cubic metre storage tanks will be erected.
