Abu Dhabi, UAE - Jereh Oil & Gas Engineering Corporation – Abu Dhabi has secured three oil and gas development packages from ADNOC Onshore worth a combined $2.7 billion, covering gas facilities at Ruwais Diyab and oilfield works at Bab and Bu Hasa.
The Abu Dhabi business is one of the main subsidiaries of Chinese group Jereh Oil & Gas Engineering, and its client is the onshore company of Abu Dhabi National Oil Company (ADNOC).
Jereh disclosed the awards in a filing to the Shenzhen Stock Exchange on 4 November. They take the form of letters of award, and formal contracts have yet to be signed, according to the company’s announcement. Jereh described the package as the highest-value single project in the group’s history.
Ruwais Diyab, an unconventional gas development, is the biggest of the three at $1.7 billion. The filing gives the exact figure as $1.704 billion, which includes $310 million of optional orders.
Under that contract, Jereh is responsible for designing, procuring, building and commissioning the facilities and pipelines. Once the field is in production, the Chinese group will operate it for five years, the company said.
The works include wellsite facilities, a central processing facility, gas gathering and product export pipelines and associated utilities, with 29 months of construction planned before operations start.
ADNOC took the final investment decision on Ruwais Diyab at ADIPEC on 2 November. The development will supply 345 million standard cubic feet per day of raw gas from 2029, potentially rising to as much as 1 billion scfd later, ADNOC said.
The second package, valued at about $600 million, covers the Bab and North East Bab oilfields over an estimated five years. Work will be released through individual orders, including connections for new oil wells and changes to existing well facilities.
A third award, worth $393 million including $174 million of optional orders, covers the Bu Hasa, Bida Qimzan and Huwaila oilfields. It carries a three-year service period.
According to Jereh, the developments are expected to help ADNOC expand hydrocarbon production capacity, strengthen its gas supply infrastructure and make its onshore assets more operationally efficient.
The company told the exchange the awards would not materially affect its 2026 financial position or operating results.
