The onshore oil and gas business of Abu Dhabi National Oil Company (Adnoc Onshore) has awarded China’s Jereh Group a contract valued at AED1.44bn ($392.1m) for the engineering, procurement and construction (EPC) of wellhead surface facilities and flowlines at the Bu Hasa cluster of oil fields in Abu Dhabi.

The cluster includes the Bu Hasa, Bida Al-Qemzan and Huwaila fields. The objective of the project is to build wellhead surface facilities and lay gathering flowlines that will connect new wells to the existing production network.

The scope of work on the project also covers the design, fabrication and installation of:

• production well module skids
• gas lift skids, which inject gas into wells to help lift the oil
• skid-mounted wellhead control panels
• solar power units

The framework agreement awarded by Adnoc Onshore on a call-off basis has a duration of 36 months, with an extendable option of 24 months, Jereh said in a filing with China’s Shenzhen Stock Exchange, where it is listed.

Adnoc Onshore is Adnoc Group’s largest production subsidiary, accounting for about 2 million barrels a day (b/d) of crude and about 7 billion cubic feet a day of associated gas from four primary onshore asset clusters: Bab, Bu Hasa, North East Bab and South East.

Maintaining and enhancing oil output levels at the Bu Hasa asset is critical to Adnoc Onshore’s contribution to parent company Adnoc Group’s target of expanding crude oil production capacity to 5 million b/d by 2027, an initiative known as Accelerated Integrated Programme 5. The state energy company’s total production capacity currently stands at approximately 4.85 million b/d.

Prior to this contract, Adnoc Onshore selected Jereh Oil & Gas Engineering Company in 2024 for a project to digitally connect 2,443 wells at the Bab, Bu Hasa and South East cluster of onshore oil fields in Abu Dhabi for remote operations. The contract, formally awarded in 2025, was valued at $920m.

Abu Dhabi contracts

The contract for the Bu Hasa wellhead facilities and flowlines is among a trio of projects totalling approximately $2.7bn that has been awarded by Adnoc Group in recent weeks, Jereh announced in its stock market filing.

The largest of the three contracts, valued at $1.7bn, is for the Ruwais Diyab unconventional gas development in Abu Dhabi. Awarded to Jereh on a design, build and operate model, the contract has a duration of 29 months for construction works and 60 months of operations, with up to two five-year extensions available.

Adnoc achieved final investment decision on the Ruwais Diyab unconventional gas development project on 2 November, during the Abu Dhabi International Petroleum Exhibition and Conference 2026.

The project will deliver 345 million standard cubic feet a day (scf/d) of raw gas from 2029 over a 25-year period, with the potential to reach up to 1 billion scf/d in the future.

The scope of work on the Ruwais Diyab project covers:

• wellsite facilities
• a central processing facility
• gas gathering pipelines and product export pipelines
• utilities

The plant will treat the raw gas and recover the liquids produced with it. It will also treat produced water, which is the water that comes up from the wells with the gas, and recover sulphur. Finished products will be delivered to designated receiving facilities.

When the operation period ends, Jereh will either hand the facilities over to Adnoc or decommission them and restore the site, as the contract and the owner require.

The third contract covers Adnoc Onshore’s Bab and North East Bab 1 tie-in project, where the main scope of work involves tying in new oil producer wells and removing and modifying surface facilities at existing producer wells.

The project’s scope also covers supporting works for water supply wells, water injection wells, disposal wells and water-alternating-gas injection wells. Several existing wells will also be upgraded with digital systems.

Jereh said the value of its contract is $599m, with a duration of 60 months. Similar to the Bu Hasa project, this contract also uses a framework model wherein Adnoc Onshore will issue work orders in batches according to its execution plans.

MEED previously reported that Adnoc Onshore had divided the scope of work on the Bab and North East Bab 1 tie-in project into 18 EPC packages. Along with Jereh, Adnoc Onshore has picked Abu Dhabi-based Robt Stone Middle East for a portion of work on the project.
