Abu Dhabi has extended the deadline for proposals to build a plant to process gas produced at the Al-Dabbiya oil field, according to sources familiar with the contact.

Project owner Abu Dhabi Company for Onshore Petroleum Operations (Adco) has asked for technical engineering, procurement and construction (EPC) to be submitted on 26 April.

Several international engineering companies have been prequalified to bid on the tender, which was floated by Adco in January.

The plant has a planned capacity to process about 250 million cubic feet a day (cf/d).

Prequalified companies are understood to include:

• GS Engineering & Construction (South Korea)
• Petrofac (UK)
• Saipem (Italy)
• Samsung Engineering (South Korea)
• SK Engineering & Construction (South Korea)
• Technip (France)
• Tecnimont (Italy)

Adco is a joint venture of Abu Dhabi National Oil Company, France’s Total (10 per cent), Japan’s Inpex (5 per cent) and South Korea’s GS Energy (3 per cent). The onshore operator is expected to award more stakes to bring the interest held by international oil companies to a total of 40 per cent.
