UAE-based Al-Asab General Contracting Company has been awarded a $175m contract to install facilities at Abu Dhabi’s onshore oil fields, according to a source familiar with the project.

The engineering, procurement and construction (EPC) contract for the Tie-in at South East (Package A) project was awarded by Abu Dhabi Company for Onshore Petroleum Operations (Adco) and is expected to take 30 months to carry out.

Under the contract, Al-Asab will supply and install tie-ins at different types of wells at the Asab, Sahil, Shah and Qusahwira fields, which make up the producing assets of Adco’s South East Asset.

The scope of work includes facilities at 54 wells on the Asab field and four wells at the Sahil field.

The contract is the second EPC deal awarded to Al-Asab by Adco in recent months. The company also won a $70m contract to replace trunk lines at Abu Dhabi’s onshore gas development.

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