Inside the Tanajib Gas Plant in Saudi Arabia: A Vital, Confidence-building Pillar of Gas Expansion

What Tanajib processes is clearly described in the sources. The plant handles associated raw gas coming from crude oil production at the offshore Marjan and Zuluf fields. Reports also note that Tanajib’s operations coincided with the start-up of the Marjan crude oil increment project, positioning the gas plant as part of an integrated upstream-and-midstream sequence rather than a standalone asset. Another source characterizes the facility as designed for digital integration and operational efficiency, reinforcing a narrative that focuses on both scale and operational readiness as the plant ramps toward its 2026 processing target.

How Tanajib Fits With Jafurah and Aramco’s 2030 Targets

Tanajib is repeatedly described as complementary to Jafurah, where Aramco confirmed first shale gas production began in December 2025. Jafurah is located across about 17,000 sq km and is estimated to contain 229 Tscf of raw gas and 75 Bbbl of condensate and liquids. Sources describe phase-one facilities producing 450 MMcfd, and they list waypoints of about 400 MMcfd in 2025, about 1.1 Bcfd in 2027, and about 2 Bcfd in 2030. By 2030, Jafurah is expected to deliver up to 2 Bscfd of sales gas, plus 420 MMscfd of ethane and approximately 630,000 bpd of high-value liquids.

Aramco places these developments inside a wider portfolio objective: increasing sales gas production capacity by about 80% by 2030 compared to 2021 levels. Another planning figure in the sources describes total gas and associated liquids production projected to reach roughly 6 MMboed under the plan. The strategic use case is also explicit. Gas from Jafurah is expected to support Saudi Arabia’s power generation needs by replacing crude currently burned for electricity, aligning with an objective to displace liquid fuels in domestic power generation and support a more resilient energy system.

Beyond volumes, the sources attach financial signals and context to the gas expansion push. Aramco estimates incremental gas volumes could generate between $12 billion and $15 billion in additional operating cash flow by 2030, subject to market conditions. Separately, contract and investment structures are cited around Jafurah’s build-out, including contracts valued at $10 billion for the first phase awarded in 2021 and $12.4 billion for the second phase awarded in 2024, plus an $11 billion lease and leaseback investment agreement for Jafurah gas processing facilities. Together with Tanajib’s 2.6 Bscfd 2026 capacity outlook, these figures show how midstream readiness and upstream supply growth are being advanced side by side.
