Rich Gas project has entered a major construction phase after ADNOC Gas awarded $8.2 billion in EPC contracts. The investment covers the second and third phases of the Abu Dhabi program. The awards will add processing and NGL fractionation infrastructure at Habshan and Ruwais. Consequently, the project will strengthen gas handling capacity while increasing recovery of higher-value liquids for export.
The latest contracts mark a significant shift from project planning into construction execution. Moreover, they reinforce Abu Dhabi’s strategy to develop more gas resources and strengthen domestic supply.
Rich Gas Project moves into construction
Phase two will add a new natural gas processing unit at the Habshan facility. Wison Engineering will deliver the unit under the EPC contract. The new train will support additional gas volumes entering Abu Dhabi’s processing network.
Habshan already anchors a major part of the UAE’s gas processing system. Therefore, expanding the facility will help accommodate rising feedstock from upstream developments.
The wider Rich Gas Development program targets a 30% increase in ADNOC Gas capacity by 2029. Phase one received a $5 billion investment and entered construction after its 2025 final investment decision.
That first phase covers upgrades at Asab, Bu Hasa, Habshan and Das Island. Wood, Petrofac and Kent received the associated EPCM contracts.
Meanwhile, the second phase adds new processing capability at Habshan. This work should improve the network’s ability to process additional gas from expanding upstream production.
Rich Gas Project adds Ruwais liquids capacity
Phase three will add a new NGL fractionation unit at Ruwais. Tecnimont, part of Italy’s Maire Group, will deliver the facility.
The Ruwais work will increase recovery of valuable liquids from processed natural gas. Those products can support exports and downstream industrial activity.
Tecnimont had already emerged as the selected contractor for the Ruwais NGL Train 5 package. The planned train will handle about 22,000 tones daily, according to industry reporting.
Wison Engineering had also been selected for the Habshan 7 gas processing train. The facility remains central to Abu Dhabi’s expanding gas infrastructure.
Together, the two phases create new processing and liquids-recovery capacity across two strategic sites. Furthermore, they connect upstream gas growth with downstream value creation.
The awards arrive as ADNOC Gas plans about $28 billion of investment between 2026 and 2030. The company expects this program to support long-term volume and earnings growth.
However, the expansion comes during a difficult operating environment. ADNOC Gas reported second-quarter 2026 net income of $665 million. That result fell 52% from $1.39 billion a year earlier.
The company also expects third-quarter net income between $600 million and $800 million. Despite those pressures, it continues advancing major infrastructure investments.
The $8.2 billion awards therefore represent more than another spending milestone. They place two major gas facilities into the next stage of project delivery.
Construction activity at Habshan and Ruwais will now become the key implementation focus. The program should also support wider gas self-sufficiency and export ambitions.
The Abu Dhabi investment also reflects wider Gulf spending on gas infrastructure. In Saudi Arabia, a $1 billion Saudi gas compression project secured an EPC contractor for a new compression facility. The parallel developments show how Gulf producers continue investing in gas infrastructure to strengthen processing capacity and supply reliability.
