Ghawar Field, Oil field in Eastern Province, Saudi Arabia
Ghawar Field is an oil field in the Eastern Province of Saudi Arabia, stretching 280 km in length and 30 km in width and recognized as the largest conventional petroleum deposit on Earth. The site contains multiple production areas and separation facilities connected through a sprawling network of pipelines.
Geologists discovered the deposit in 1948 by recognizing geological uplift patterns, and the first successful extraction began in 1951 at the Ain Dar No. 1 well. Commercial operations developed gradually over the following decades into the country's most important petroleum source.
This petroleum reserve fundamentally shaped Saudi Arabia's economic landscape, generating over half of the nation's total oil production since commercial operations began.
Access to the site is strictly limited to authorized personnel, and visitors cannot view the production facilities up close. The surrounding region remains largely inaccessible due to industrial activity and security measures.
The Arab-D reservoir beneath the field contains limestone formations with exceptional porosity levels reaching 35 percent, allowing substantial oil accumulation and extraction. This geological characteristic sets the deposit apart from most other petroleum reserves worldwide.
