Saudi Aramco's Marjan Field Upgrade: What KBR's New Contract Means for Output

On 6 October 2026, Saudi Aramco awarded KBR, a U.S.-headquartered engineering firm, a key contract to upgrade its Marjan offshore oil and gas field. This move aims to maintain the field's production capacity and significantly advance its gas processing capabilities, a crucial step for Saudi Arabia's long-term energy strategy and economic diversification goals.

What KBR's New Contract Means for Marjan

KBR will provide engineering and project execution services for the offshore processing, gas compression, and power infrastructure facilities within the Marjan field (Globenewswire). This involves integrating digital technologies, automation, and power system enhancements to modernise the existing infrastructure. The engineering work for this undisclosed financial agreement will primarily be conducted from KBR's offices in Houston, USA, and Al-Khobar, Saudi Arabia, reflecting KBR's decades-long relationship with Aramco (Globenewswire, Euro-petrole).

The Marjan field, discovered in 1967 in the Arabian Gulf, has been a cornerstone of Saudi Arabia's oil production for decades. Its initial recoverable crude oil estimates stood at 2.31 billion barrels. Over time, its production capacity grew significantly, reaching 600,000 barrels per day (bpd) of oil and 675 million standard cubic feet per day (Mscfd) of gas with the installation of GOSP-2 and GOSP-3 in 1994 (Offshore-technology). The current upgrade is part of the broader Marjan Crude Increment Programme, announced in 2017, which aims to boost the field's crude production capacity by 300,000 bpd, eventually reaching 800,000 bpd by 2025 (Offshore-technology). This programme also targets an additional 360,000 bpd of ethane and natural gas liquids (NGL) by processing an extra 2.5 billion standard cubic feet per day (Bscfd) of gas from the field (Offshore-technology).

Why Saudi Aramco is Investing Billions in its Fields

This multi-billion-dollar investment in Marjan is part of Saudi Aramco's strategy to enhance its oil production and gas processing capabilities, reinforcing its position as a leading integrated energy supplier. The Marjan Crude Increment Programme alone represents an estimated total investment of $12 billion, with $5 billion allocated for offshore work and up to $7 billion for onshore packages (Offshore-technology). This larger expansion is part of Saudi Aramco's $18 billion investment to boost capacity across both the Marjan and Berri offshore fields by 550,000 bpd of crude oil and 2.5 Bscfd of gas (Offshore-technology).

The project aligns directly with Saudi Arabia's Vision 2030, which seeks to diversify the economy, increase gas production and distribution capacity, and localise the oil and gas sector. By maintaining its maximum sustained oil production capacity at approximately 12 million bpd, Saudi Arabia aims to compensate for potential declines in other mature fields (Oilandgasmiddleeast). Developing gas resources, such as those from Marjan, is also critical for the Kingdom to displace crude oil from domestic power generation, provide feedstock for its expanding petrochemical industry, and support emerging blue hydrogen production initiatives (Oilandgasmiddleeast). Middle Eastern national oil companies are making substantial capital investments to maintain their international leadership in the oil and gas sector, with Saudi Arabia's upstream oil and gas investment projected to be the highest in the region, reaching about $40 billion in 2025 (Oilandgasmiddleeast).

What This Investment Means for the Saudi Economy

For KBR, the contract reflects its strong, long-standing relationship with Aramco and leverages its expertise in offshore engineering, advanced automation, and digital integration (Globenewswire). For Saudi Aramco, the project secures the long-term performance of critical offshore assets and ensures its role as a stable energy supplier. The integration of digital technologies, such as Artificial Intelligence (AI) and the Internet of Things (IoT), also aligns with broader investments in AI infrastructure across the Kingdom (Globenewswire).

From a wider economic perspective, the Marjan expansion is a significant component of Saudi Aramco's multi-billion dollar investment programme, contributing to the Kingdom's economic development. This supports the goals of Vision 2030, particularly the drive to increase localisation within the oil and gas sector (Oilandgasmiddleeast). Such large-scale infrastructure projects create jobs and stimulate local industries, feeding into the broader economic diversification efforts.

What to Watch Next for Saudi Energy

Investors and businesses should watch for the completion of the Marjan Crude Increment Programme, including the Tanajib gas plant, which is expected by 2025 (Offshore-technology). Following this, the Marjan field's crude production capacity is projected to reach 800,000 bpd. Saudi Aramco has ambitious plans, with 110 projects scheduled between 2024 and 2026, 67 of which focus on oil, gas, and petrochemicals (Oilandgasmiddleeast). Total oil and gas supply investment in the Middle East is projected to be around $130 billion in 2025 (Oilandgasmiddleeast).

Furthermore, the upcoming independent audit by OPEC+ of its member states' production capacities will redefine 2027 baselines. High-investment members like Saudi Arabia may seek formal recognition of their expanded capacities, which could influence future supply quotas (Oilandgasmiddleeast). The Kingdom is also exploring new land-based oil export routes to bypass the Strait of Hormuz, a strategic move driven by geopolitical tensions to safeguard supply reliability (Oilandgasmiddleeast). This could lead to further significant infrastructure projects in the near future, building on existing efforts like the surge in Red Sea oil exports [/news/saudi-oil-pipelines-global-supply-security].

The bottom line

KBR's contract for Saudi Aramco's Marjan field upgrade is a strategic investment to maintain and enhance the Kingdom's critical energy infrastructure. This project underscores Saudi Arabia's commitment to securing its long-term oil production capacity and expanding its gas processing capabilities, aligning with its Vision 2030 goals for economic diversification and energy leadership.
