Aramco commissions Zuluf field oil increment project

5 November 2026

Saudi Aramco has announced the start of oil production at the Zuluf oil increment project in Saudi Arabia, on which it is estimated to have spent about $7bn in 2022.

The Saudi energy company made the announcement as part of its third-quarter 2026 financial results, in which it reported adjusted net income of $31.2bn, up 9% year on year.

The Zuluf oil increment project involved substantial onshore and offshore work at the field, located in the Gulf about 40 kilometres off Saudi Arabia’s northeastern coast.

The engineering, procurement and construction (EPC) scope was divided into two onshore packages and five offshore packages.

Aramco selected Japan’s JGC Holdings Corporation in May 2022 for the two main onshore packages of the Zuluf field development. Together, the packages were estimated to be worth up to $3.5bn.

Package 1 was estimated to be the larger of the two onshore packages, with a contract value of about $2bn-$2.5bn. It covered EPC work to build hydrocarbon-processing facilities for the Zuluf development, principally an onshore gas-oil separation plant.

Package 2 covered utilities and water-injection facilities and was estimated to be worth about $1bn.

Before awarding the onshore contracts, Aramco had awarded more than $4bn of contracts across five main offshore engineering, procurement, construction and installation packages. The awards went to US-headquartered McDermott International; a consortium of India’s Larsen & Toubro Hydrocarbon Engineering and UK-headquartered Subsea7; and Abu Dhabi’s NMDC Energy, then known as National Petroleum Construction Company.

Since the 2022 EPC awards, Aramco has invested further in maintaining and upgrading infrastructure at the Zuluf field. The work supports the company’s objective of maintaining its maximum sustained crude oil production capacity at 12 million barrels a day (b/d).

Other upstream projects

In its Q3 2026 results statement, Aramco also announced EPC progress on other key upstream oil and gas projects, including:

Jafurah phase two – Aramco awarded 16 contracts, worth a combined total of about $12.4bn, on 30 June 2024 for the second expansion phase of the Jafurah unconventional gas development programme in the Eastern Province.

The second phase aims to raise the field’s processing potential to up to 2 billion cubic feet a day (cf/d) of raw gas. The EPC scope of work includes constructing gas compression facilities and associated pipelines, and expanding the Jafurah gas plant, including the construction of gas processing trains, utilities, sulphur and export facilities, Aramco said in a statement.

Fadhili gas plant expansion – Through the estimated $7.7bn project, Aramco aims to increase the Fadhili gas plant’s processing capacity from 2.5 billion cf/d to up to 4 billion cf/d. The expansion includes three new processing trains, each with a capacity of 500 million cf/d.

Aramco awarded contracts for four main EPC packages of the Fadhili gas plant expansion project in April 2024 to South Korean contractors Samsung E&A and GS Engineering & Construction and Saudi contractor Nesma & Partners.

Dammam development project – The project represents the second development phase of the Dammam field. Its objective is to install infrastructure, including pipelines, trunklines and pumps, to increase the field’s crude oil production capacity by 25,000 b/d and 50,000 b/d in separate phases.

Al-Khobar-based Denys Arabia won the main EPC contract for the Dammam second field development phase in July 2024. The contract was estimated to be worth more than $500m.
