Ghawar is the largest conventional onshore oil field ever discovered, located in Saudi Arabia’s Eastern Province and operated by Saudi Aramco. Saudi Arabia’s total crude oil and liquids production stood at 10.3 million barrels per day in 2024, with Aramco holding a maximum sustainable production capacity of 12 million barrels per day for 2025-2026, according to the U.S. Energy Information Administration. Ghawar alone has historically supplied roughly half of that national total, though Aramco does not publish a standalone current-year figure for the field โ more on exactly where to find one below.

Ghawar Oil Field: Current Status and Production
Ghawar was discovered in 1948 and began production in 1951. It stretches roughly 280 kilometers north to south and 30 kilometers east to west in Saudi Arabia’s Eastern Province, and its original recoverable reserves were estimated at more than 70 billion barrels. Those historical facts don’t change. What does change โ and what most pages answering “ghawar oil field current status” get wrong โ is the production figure, because Aramco stopped publishing field-by-field daily output decades ago for competitive and strategic reasons.
Here is what is actually published: Saudi Arabia’s total crude oil and liquids production was 10.3 million barrels per day in 2024, reported by Saudi Aramco and compiled in the International Trade Administration’s Saudi Arabia oil, gas and petrochemicals guide. Separately, the EIA states Aramco’s maximum sustainable production capacity for 2025-2026 is 12 million barrels per day. Neither source breaks that figure down by field. Any number you see quoted for “Ghawar’s current daily output” โ including figures that circulated for years citing roughly 5 million barrels per day โ is either an older estimate, a modeled third-party figure, or an extrapolation, not an Aramco-published current statistic.
Why there’s no clean “Ghawar produces X barrels today” answer
- Field-level data isn’t public. Aramco reports national and segment-level production in its quarterly and annual investor filings, not per-field breakdowns for legacy fields like Ghawar.
- Enhanced oil recovery changes the baseline. Water flooding and gas injection at Ghawar offset natural pressure decline, so even a correct historical figure drifts over time without new data.
- Production shifts with OPEC+ quotas. Saudi Arabia adjusts national output in coordination with OPEC+ agreements, which moves the country total independent of any single field’s physical capacity.
Saudi Arabia’s Reserves: What’s Actually Proven
As of December 2024, Saudi Arabia held 190.2 billion barrels of proven crude oil and condensate reserves, per Saudi Aramco’s disclosure cited in the International Trade Administration’s country commercial guide. The same disclosure puts proven natural gas reserves at 209.8 trillion standard cubic feet as of December 2024. These are point-in-time figures tied to a specific reporting date, not a running total โ Aramco restates them periodically as new discoveries are added and production is drawn down.
Ghawar’s share of that national reserve figure is not separately disclosed. The field’s original recoverable estimate of over 70 billion barrels is a historical figure from decades of study, not a current remaining-reserves number, and no dated 2025 or 2026 figure for Ghawar’s remaining reserves appears in Aramco’s public disclosures.
New Discoveries: The Fields Feeding Future Output
Saudi Arabia’s Ministry of Energy and Aramco announced eight new oil field discoveries and six new gas field discoveries in 2025. Two of the named discoveries have published initial production-test rates: the Ayfan field tested at 2,840 barrels per day of Arabian Extra Light crude, and the Ghizlan gas field tested at 32 million cubic feet per day, according to Aramco’s announcement covered by DrillingContractor.org and the Global Energy Prize. These are initial test rates, not sustained commercial production volumes โ a distinction worth keeping in mind before comparing them to Ghawar’s field-wide scale.
Beyond new discoveries, Aramco is expanding existing offshore and onshore fields. The Zuluf field expansion is planned to add 600,000 barrels per day of production capacity in 2026, and the Marjan field expansion targets a 300,000 barrel-per-day crude increment in 2025, per project tracking from Ventures Onsite. Supporting that growth, the Tanajib Gas Plant โ built to process gas from the Marjan and Zuluf fields โ reached a processing capacity of 2.6 billion standard cubic feet per day as of December 2025.
Reading a “new field” announcement correctly
- Test rate โ commercial output. Ayfan’s 2,840 bpd and Ghizlan’s 32 million cf/d are what flowed during appraisal testing, before a field is fully developed and tied into infrastructure.
- “Discovery” doesn’t mean “reserve estimate published.” Saudi Arabia’s 2025 discovery announcements did not include barrel-count reserve estimates for the individual new fields.
- Expansion projects use planned, not actual, figures until completion is confirmed. The Zuluf and Marjan numbers above are stated capacity targets for 2025-2026, sourced from project-tracking data, not confirmed flow rates.
Aramco: Scale, Structure, and Where the Numbers Come From
Saudi Aramco โ officially the Saudi Arabian Oil Company โ is the operator behind essentially all of the production and reserve figures in this article. Its scale comes from two things: the underlying resource base (190.2 billion barrels of proven crude and condensate reserves, 209.8 trillion cubic feet of proven gas, both as of December 2024) and a maximum sustainable production capacity of 12 million barrels per day targeted for 2025-2026, per the EIA’s Saudi Arabia country analysis.
For anyone tracking Aramco as a company rather than an oil producer โ market capitalization, share price, dividend policy โ that data lives in Aramco’s investor relations disclosures and stock exchange filings, not in the oil-production sources cited in this article, and this piece does not restate unsourced market-cap figures. What we can confirm from primary sources is operational: national production of 10.3 million barrels per day in 2024, and the 12 million barrel-per-day capacity ceiling for 2025-2026.
Siemens Energy in Saudi Arabia: The Power Side of the Story
Oil and gas production in Saudi Arabia depends on power generation capacity to run pumps, compressors and processing facilities, which is where Siemens Energy fits in. Siemens Energy secured a $1.5 billion contract covering the Taiba 2 and Qassim 2 power plants, plus a 25-year maintenance agreement, with the plants scheduled for 2026-2027. The Taiba 2 plant alone carries a capacity of 2,000 megawatts, according to Siemens Energy’s own press release.
This is a power-generation contract, not an oil-field development contract โ Taiba 2 and Qassim 2 supply electricity to the grid rather than processing crude directly. The connection to the oil and gas sector is indirect: reliable, large-scale power capacity supports the electrification of new field developments like Zuluf and Marjan as they come online through 2026.
What an FPSO Actually Is โ and Why Ghawar Doesn’t Use One
An FPSO โ Floating Production Storage and Offloading unit โ is a ship-shaped vessel that extracts, processes, stores and offloads oil or gas from an offshore field without a fixed platform. It matters for this topic mainly by contrast: Ghawar is an onshore field, so FPSOs play no role in its operations. FPSOs matter to Saudi Arabia’s offshore developments in the Persian Gulf and Red Sea, where seabed conditions or water depth make a fixed platform less economical.
Here is the honest gap in the public record: no dated, sourced FPSO vessel deployment, name, or capacity specification for a Saudi Aramco offshore project turned up in the research for this article. Claims about “the world’s biggest FPSO” being an Aramco vessel, or specific throughput and storage figures attributed to a named Saudi FPSO, are not backed by a citable primary source here. If you’re researching a specific FPSO contract, the reliable path is Aramco’s project-award announcements and classification-society vessel registries (DNV, ABS, Lloyd’s Register), which publish named vessel specifications when a unit is delivered โ not general news aggregation.
How FPSOs work, mechanically
- Extraction and processing: risers bring oil and gas up from subsea wells to onboard separation trains that split oil, gas, water and sediment.
- Storage: processed crude is held in the vessel’s hull tanks until a shuttle tanker arrives.
- Offloading: crude is transferred to tankers via hose systems, avoiding the need for a pipeline to shore.
- Redeployment: because it’s a vessel rather than a fixed structure, an FPSO can be towed to a different field once one reservoir depletes.
That mobility is the entire commercial case for an FPSO over a fixed platform: it lets an operator develop a marginal or remote offshore field without committing to permanent infrastructure, and reuse the vessel elsewhere once production winds down. For a deeper technical breakdown of FPSO capacity classes and offshore field economics, see our dedicated analysis: largest oil field and FPSO offshore developments.
“World’s Largest Oil Field”: Ghawar vs. the Competition
Ghawar holds the title of largest conventional oil field by original recoverable reserves โ over 70 billion barrels โ and by physical footprint, at roughly 280 by 30 kilometers. That title is about the reservoir, not about which country currently pumps the most oil in total: national production rankings (United States, Saudi Arabia, Russia) are a separate question from single-field size, and conflating the two is the most common error in casual references to “the world’s largest oil field.”
No competing field โ including Burgan in Kuwait or the Permian Basin’s individual sub-fields in the United States โ has publicly documented original recoverable reserves exceeding Ghawar’s historical estimate. The Permian Basin as a whole outproduces Ghawar in aggregate because it’s a multi-field shale province spanning thousands of individual wells across Texas and New Mexico, not a single conventional reservoir โ a structurally different kind of comparison than field-to-field.

Calculator: Field Output vs. National Share
Because Ghawar’s field-level output isn’t published, this calculator lets you test what a given field’s share of Saudi Arabia’s national production would mean in practical terms โ plug in any daily barrel figure you find in a dated source, and compare it against the confirmed 2024 national total of 10.3 million barrels per day.
Assumptions: this tool does no forecasting and holds no live price feed โ it only does arithmetic on the two numbers you enter. It excludes taxes, transport cost, and quality differentials (Arabian Light vs. Arabian Extra Light pricing differs). Use it to sanity-check a claimed field output against the confirmed 2024 national total, not as a valuation tool.
Farmonaut’s Satellite Mineral Intelligence
Hydrocarbon fields like Ghawar are found and managed with subsurface seismic data built up over decades. Mineral exploration for metals โ gold, copper, lithium, rare earths โ increasingly uses a different toolkit: satellite-based remote sensing paired with AI pattern recognition, which shortens the early-stage search before a single drill hole is sunk. Farmonaut operates in this space, running a satellite-based mineral detection platform for exploration companies and investors.
How the analysis works
- Multispectral and hyperspectral satellite imagery is screened for mineral and alteration signatures characteristic of specific deposit types.
- AI-driven pattern recognition flags target zones, alteration halos, faults, and structural features associated with mineralization.
- Reports include high-resolution maps and 3D models supporting drill-targeting decisions, without ground disturbance at the screening stage.
The approach applies to precious metals, battery minerals (lithium, cobalt, nickel), base metals (copper, zinc, iron), and rare earths. For the full breakdown of use cases, methodology and workflow, see Farmonaut’s Satellite-Based Mineral Detection page.
Clients submit coordinates, a target region, and minerals of interest; Farmonaut selects the appropriate data source and runs its analysis workflow, with final reports โ including commercial guidance and drill-targeting recommendations โ typically delivered in 5 to 20 business days depending on area size and data availability.

FAQ: Ghawar, Aramco, and FPSOs
What is the current status of the Ghawar oil field?
Ghawar remains in active production under Saudi Aramco, using enhanced oil recovery (water flooding and gas injection) to offset natural pressure decline. Aramco does not publish a current field-level daily output figure; the closest verifiable proxy is Saudi Arabia’s national production of 10.3 million barrels per day in 2024, alongside Aramco’s stated maximum sustainable capacity of 12 million barrels per day for 2025-2026.
What is Ghawar field’s current production for 2025 or 2026?
No dated, field-specific 2025 or 2026 production figure for Ghawar is published in Aramco’s public disclosures or in EIA/ITA reporting. See the “How to Verify” section below for the exact primary sources to check for an updated figure.
What is the world’s largest oil field?
Ghawar, discovered in 1948 in Saudi Arabia’s Eastern Province, is the largest conventional oil field ever found by original recoverable reserves, estimated at more than 70 billion barrels. That ranking is about a single reservoir’s scale, not national production totals, which are calculated differently.
How large are Saudi Arabia’s oil and gas reserves?
190.2 billion barrels of proven crude oil and condensate, and 209.8 trillion standard cubic feet of proven natural gas, both as of December 2024, per Saudi Aramco’s disclosure in the International Trade Administration’s country guide.
What is an FPSO and does Ghawar use one?
An FPSO (Floating Production Storage and Offloading unit) is a vessel that extracts, processes, stores and offloads oil or gas from offshore fields. Ghawar is onshore and does not use FPSOs; FPSOs apply to Saudi Arabia’s offshore Persian Gulf and Red Sea developments instead.
What is Aramco’s role in these figures?
Saudi Aramco is the operator and source of essentially every production and reserve figure cited here, reporting a 2024 national output of 10.3 million barrels per day and a targeted maximum sustainable capacity of 12 million barrels per day for 2025-2026.
What is Siemens Energy’s current project in Saudi Arabia?
A $1.5 billion contract for the Taiba 2 (2,000 megawatts) and Qassim 2 power plants, including a 25-year maintenance agreement, with delivery scheduled for 2026-2027.

How to Verify These Numbers Yourself
Every figure in this article carries a publication date because oil and gas data ages fast โ a number that’s accurate for 2024 can be superseded within a quarter. Here’s exactly where to look for a fresher one, by category:
- Ghawar or any field’s current production: Saudi Aramco’s quarterly investor relations reports (published on Aramco’s investor relations site) carry the most current disclosed figures, typically with roughly a 30-day lag after quarter-end. Cross-check against the EIA’s OPEC production database, updated monthly.
- New oil or gas field discoveries: The Saudi Ministry of Energy issues press releases when discoveries are announced; MEED and Arab News publish English-language summaries shortly after.
- Siemens Energy project milestones: Siemens Energy’s own newsroom (siemens-energy.com/news) posts quarterly project updates and milestone completions for contracts like Taiba 2 and Qassim 2.
- Reserve estimates: Aramco restates proven reserves periodically; the most recent figure will appear in the same International Trade Administration country guide or in Aramco’s annual report.
The throughline across Ghawar, Aramco’s reserve base, the 2025 discoveries, and the Siemens power contracts is the same: none of these are static facts you memorize once. They’re figures with a vintage and a refresh cycle, and the durable skill is knowing which primary source updates them and how often โ not memorizing this quarter’s number.
