Saudi Aramco has extended the deadline for bids on its planned Uthmaniyah ethanol feed recovery project, according to sources familiar with the scheme.

Contractors have been invited to submit engineering, procurement and construction (EPC) bids by the end of June, pushing the date back from 31 May.

The project, estimated to be valued at $800m-$900m, will involve the recovery of ethane, propane and natural gas liquids (NGLs) from sales gas at the plant site in the east of the kingdom.

Aramco tendered the EPC contract in March. The companies prequalified to bid are:

• CTCI (Taiwan)
• Daewoo Engineering & Construction (South Korea)
• GS Engineering & Construction (South Korea)
• Hyundai Engineering & Construction (South Korea)
• JGC (Japan)
• Petrofac (UK)
• Saipem (Italy)
• Samsung Engineering (South Korea)
• Tecnicas Reunidas (Spain)

The Uthmaniyah gas plant processes associated gas produced from the Ghawar field – the largest-producing oil field in Saudi Arabia and the largest known field in the world based on reserves.

Aramco CEO Amin Nasser said in early March that the kingdom’s gas network now produces 12 billion cubic feet a day (cf/d) and there are plans to increase this to 23 billion cf/d.

Aramco’s projects at the Fadhili, Midyan and Wasit fields are set to add more than 5 billion cf/d of non-associated gas processing capacity.
