Ghawar Field sits under the Eastern Province of Saudi Arabia. It is not a secret. Geologists have known about it for decades. What matters now is that Saudi Aramco still runs it, and still calls it the world’s largest onshore oil field. The company manages more than one hundred oil and gas fields across the kingdom. Ghawar and Safaniya, the offshore giant, are just two of them. That scale is the story.
Saudi Aramco reported 12.7 million barrels of oil equivalent per day in 2024. That number is production, not capacity. It is what actually came out of the ground and moved through pipes. To put that in context, the company holds more than 270 billion barrels of proven crude oil reserves. That is the largest single corporate reserve base on earth. No other oil company comes close. Not Exxon. Not Shell. Not PetroChina.
The Master Gas System ties it all together. Saudi Aramco calls it the world’s largest single hydrocarbon network. It moves crude, natural gas, and natural gas liquids across the country. The system feeds power plants, petrochemical complexes, and desalination plants. It is a piece of infrastructure that most people never see, but it makes the Saudi economy run.
Natural gas reserves stand at 288.4 trillion standard cubic feet. That number puts Saudi Aramco in the top tier of global gas players. The company has not pushed gas as hard as oil historically. That may change. Gas burns cleaner than oil. It can feed hydrogen production. It can feed power generation. The reserves are there. The question is how fast Aramco develops them.
The company headquarters sits in Dhahran. That is in the Eastern Province, near the giant fields. It is not in Riyadh, the political capital. It is not in Jeddah, the commercial hub. It is in Dhahran, a company town built around oil. The location tells you something about how the company operates. It is physically close to its assets. It is not a trading desk in London or a corporate office in Houston. It is a production machine planted on top of the oil.
Saudi Aramco listed on the Saudi Exchange on 11 December 2019. Shares opened at 35.2 Saudi riyals. That gave the company a market capitalisation of roughly US$1.88 trillion. That valuation made it the most valuable listed company in the world at the time. It has since been overtaken by technology firms. But the underlying asset base has not shrunk. The oil is still there. The gas is still there. The production capacity is still there.
The company is the fourth-largest in the world by revenue as of 2024. That ranking includes all companies, not just oil companies. It sits behind Walmart, Amazon, and a few others. But those companies sell consumer goods and cloud services. Saudi Aramco sells a commodity that the global economy cannot function without. That gives it a different kind of power.
Daily oil production of 12.7 million barrels per day is not a steady number. It fluctuates based on OPEC quotas, market demand, and field maintenance. But the underlying capacity is higher. The company has spare capacity that it can bring online when needed. That spare capacity is a strategic asset for Saudi Arabia and for global oil markets. When something goes wrong in Venezuela or Libya or Nigeria, the world looks to Saudi Aramco to fill the gap.
The Ghawar Field alone has produced more oil than any other field in history. It is still producing. It is not in decline. The company has invested in water injection and enhanced recovery techniques to keep pressure in the reservoir. That work is not glamorous. It is engineering. It keeps the oil flowing.
Safaniya is the offshore counterpart. It sits in the Persian Gulf. It produces heavy crude, which refineries need for certain products. The company runs both fields as part of a single integrated system. That system is the backbone of the Saudi economy and a significant part of the global energy supply.
