Saudi Arabia’s oil and gas sector is anchored by Saudi Aramco as the dominant state-owned operator, alongside SABIC, Saudi Chevron, Sadara Chemical Company, Petro Rabigh, and a layer of international oilfield-services firms — Halliburton, Baker Hughes, Schlumberger, and Weatherford — that run Saudi operations under license or joint venture. The country produced 3.462 billion barrels of crude oil in 2025, exported 2.347 billion barrels of it, and holds 267.23 billion barrels in proven reserves — the world’s second-largest, according to the Saudi Arabia General Authority for Statistics. This article lists the companies by segment, ranks them against real production and reserve figures, and gives you a way to check whether those numbers have moved since this was written.

Introduction: Who Actually Runs Saudi Arabia’s Oil and Gas Sector

Searching for “oil companies in Saudi Arabia” mostly returns one name — Saudi Aramco — because it dwarfs everything else in the Kingdom by output. Aramco’s own reported figures put total hydrocarbon production at 12.9 million barrels of oil equivalent per day in 2025, with a maximum sustainable crude oil production capacity of 12 million barrels per day, per Aramco’s official capacity statement (via Argaam). But Aramco is not the whole industry. Downstream petrochemicals run through SABIC; upstream joint-venture production in the Saudi-Kuwait Partitioned Zone runs through Saudi Chevron and Al-Khafji Joint Operations; and drilling itself — the physical act of putting a well in the ground — is contracted out to specialist firms like SADCO, Dallah Drilling Company, and international service majors operating Saudi subsidiaries.

This article separates those three categories — producers, downstream/petrochemical operators, and drilling contractors — and attaches real 2025 production and reserve numbers to each where they’re published. Where a number isn’t publicly broken out by company (which is common for joint ventures and service contractors), we say so and point to where you’d look to verify a current figure yourself.

Saudi Arabia’s Oil and Gas Landscape: The Numbers Behind the Headlines

Saudi Arabia holds 267.23 billion barrels of proven oil reserves, ranking second worldwide behind Venezuela, according to Worldometer’s compilation of Saudi Arabia General Authority for Statistics figures. In 2025, the Kingdom’s annual crude oil production reached 3.462 billion barrels, a 5.6% increase over the prior year, and annual crude exports totaled 2.347 billion barrels — meaning roughly 68% of crude output left the country as exports, with the remainder feeding domestic refining and petrochemical feedstock (Saudi Arabia General Authority for Statistics, via ZAWYA).

On the US side of that trade relationship: US imports of Saudi crude oil and petroleum bituminous minerals were valued at $7.06 billion in 2025, according to Trading Economics’ compilation of US trade data. That’s a small share of total US crude imports (the US sources most of its crude from Canada and Mexico), but it remains a benchmark figure for anyone tracking US-Saudi energy trade exposure.

• Reserves: 267.23 billion barrels proven (Worldometer/Saudi Statistics, 2025) — world rank #2.
• Annual production: 3.462 billion barrels crude oil in 2025, up 5.6% year-over-year (Saudi Statistics/ZAWYA).
• Annual exports: 2.347 billion barrels crude oil in 2025 (Saudi Statistics/ZAWYA).
• Sector breadth: upstream (exploration and production), midstream (transport and storage), and downstream (refining and petrochemicals).
• US trade link: $7.06 billion in US imports of Saudi crude oil in 2025 (Trading Economics).

Price context matters as much as volume for anyone evaluating the sector’s revenue trajectory. Brent crude averaged $69.14 per barrel and WTI averaged $65.39 per barrel across 2025, according to Statista’s compilation of EIA spot price data. Those annual averages are the benchmark most Aramco and OPEC+ production decisions are measured against — a $4-5 spread between Brent and WTI that’s held fairly consistently through the year.

Overview Table of Key Oil and Gas Companies in Saudi Arabia

The one company in this table with hard, cited 2025 numbers is Aramco — because Aramco’s production capacity and revenue are disclosed to investors under Tadawul listing rules. SABIC, Sadara, Petro Rabigh, Saudi Chevron, and Sipchem don’t publicly break out barrel-equivalent or tonnage figures at the level of granularity this table would need to cite honestly; where our research turned up no verifiable 2025-26 figure for a company, we’ve said so directly rather than estimate one. For company-specific production or capacity data beyond what’s shown here, each company’s investor relations page or Tadawul (the Saudi stock exchange) filing is the primary source — the Aramco figures above came from Aramco’s own capacity statement via Argaam.

List of Drilling Companies in Saudi Arabia: The Upstream Backbone

Drilling companies are contractors, not resource owners — they get paid to put wells in the ground and keep them producing, whether the reservoir belongs to Aramco or a joint venture. Here are the firms doing that work across the Kingdom:

• SADCO (Saudi Arabian Drilling Company) — the leading local rig operator, running onshore and offshore drilling programs for Aramco under a long-standing joint-venture structure with Nabors Industries.
• Dallah Drilling Company — specialized in oil well drilling, with a focus on safety and integration of modern rig technologies.
• National Drilling Company — based in Abu Dhabi but active within the Kingdom, offering exploration, well maintenance, and field development services.
• Schlumberger Saudi Arabia — regional branch of the global oilfield services leader.
• Halliburton Saudi Arabia — drilling solutions, well completion, and field digitalization across multiple KSA projects.
• Weatherford Saudi Arabia — well drilling, intervention, and rig operations.

Rig-count and fleet-size figures for individual drilling contractors (SADCO, Dallah, National Drilling Company) were not available in the sources used for this piece. Nabors Industries — SADCO’s international JV partner — publishes fleet data in its quarterly investor filings, which is the most direct way to verify a current Saudi rig count tied to that specific joint venture.

To complement on-ground drilling activity, remote analysis of mineral-rich terrain is increasingly used for early-stage exploration decisions. Explore the benefits of satellite-driven mineral intelligence to accelerate project pipeline decisions before committing rig time to a target.

Oil & Gas Industry Infrastructure and Strategic Importance

Saudi Arabia’s oil and gas infrastructure spans production fields, refineries, export terminals, pipeline networks, and gas-processing plants, operated jointly by Aramco, its downstream affiliates, and the drilling contractors listed above.

• Strategic export points: facilities at Ras Tanura, Yanbu, Jubail, Rabigh, and Jeddah.
• Pipeline network: the East-West pipeline links Gulf-side production to Red Sea export terminals, bypassing the Strait of Hormuz for a portion of export volume.
• Maritime access: proximity to Persian Gulf and Red Sea shipping lanes supports the export volumes cited above — 2.347 billion barrels of crude in 2025 alone.
• Digital field operations: ongoing upgrades in monitoring, automation, and data analytics across major fields.

Coordination between producers, drilling firms, and engineering providers keeps this infrastructure operational at the scale needed to sustain Aramco’s 12 million barrel-per-day maximum sustainable capacity — a figure that represents spare capacity headroom above 2025’s actual daily crude output of roughly 9.56 million barrels/day.

Current Trends & Sector Outlook

A few shifts define the state of play in Saudi oil and gas right now, each tied to a verifiable data point rather than a general trend claim:

• Spare capacity headroom: Aramco’s maximum sustainable capacity of 12 million barrels/day sits well above its 2025 daily crude output of 9,556,054 barrels/day — roughly 2.4 million barrels/day of spare capacity, a figure OPEC+ quota decisions directly reference.
• Natural gas expansion: the Jafurah unconventional gas project reached 450 million cubic feet/day of operational output by December 2025, against reserves estimated at 15 trillion cubic feet — though a national total for Saudi natural gas production wasn’t available in the sources reviewed for this piece; Aramco’s annual report is the primary place to check that figure.
• Price sensitivity: with Brent averaging $69.14/barrel and WTI $65.39/barrel across 2025 (Statista/EIA), Aramco’s $436.61 billion 2024 revenue figure gives a sense of scale for how a $5-10 swing in annual average price translates into tens of billions in revenue impact.
• Downstream diversification: continued investment across SABIC, Sadara, and Petro Rabigh into petrochemicals and specialty chemicals, reducing the sector’s dependence on crude export volume alone.

Emerging Technologies: Efficiency, Recovery & Sustainability in Saudi Oil and Gas

The technologies shaping output and efficiency across Saudi fields include:

• Enhanced Oil Recovery (EOR): water flooding, CO₂ injection, and polymer flooding techniques used to extend reservoir life on mature fields.
• Satellite and remote sensing: supports resource mapping and exploration-stage decision-making ahead of committing drilling budget. If your team needs satellite-based mineral detection for early exploration, this reduces upfront cost and surface disturbance before any rig mobilizes.
• Drilling automation: AI-assisted rig controls and predictive maintenance reduce downtime across onshore and offshore operations — see the drilling automation overview for how this changes well-cost economics.
• Carbon Capture and Storage (CCS): deployed at scale as part of the Kingdom’s emissions targets tied to Vision 2030.

Barrel-to-Revenue Calculator

Use the sliders below to estimate a company’s or field’s annual revenue at a given daily production rate and benchmark price — plug in Aramco’s own figures, or your own project’s numbers, to see how sensitive revenue is to price swings.

Assumes a constant daily production rate and a single flat benchmark price across the whole period — it ignores price volatility, production curtailments, OPEC+ quota changes, and the Brent/WTI spread. Export-share revenue is a simple percentage split, not a netback after transport, refining, or discount/premium adjustments. Default values are Saudi Arabia’s 2025 crude output (9,556,054 bbl/day) and 2025 Brent average ($69.14/barrel) per Worldometer/Saudi Statistics and Statista/EIA.

Frequently Asked Questions: Oil and Gas Companies in Saudi Arabia

Conclusion: Reading the List Correctly

The list of oil and gas companies in Saudi Arabia has one dominant name — Saudi Aramco, with 12 million barrels/day of maximum sustainable crude capacity and $436.61 billion in 2024 revenue — and a second tier of downstream operators (SABIC, Sadara, Petro Rabigh, Sipchem) and joint-venture producers (Saudi Chevron, Al-Khafji Joint Operations) whose company-specific output figures aren’t broken out in public Saudi statistics at the granularity this piece could verify. Around both sits a layer of drilling and oilfield-services contractors — SADCO, Dallah, and the Saudi units of Halliburton, Schlumberger, Baker Hughes, NOV, and Weatherford — that get paid to do the physical work of finding and maintaining wells without owning the reserves themselves.

The durable way to re-check any number in this article: for national production, reserves, and export volumes, go to the Saudi Arabia General Authority for Statistics directly or via Worldometer’s compiled series; for Brent/WTI pricing, use the EIA’s Short-Term Energy Outlook, updated quarterly; for Aramco-specific capacity and revenue, use Aramco’s investor relations filings and Tadawul disclosures. For every other company named here, the same approach — investor relations page or Tadawul filing — is the only reliable route to a current figure, since public aggregators haven’t consistently reported company-level breakdowns for the non-Aramco players.
