Quick Summary

Al-Hasa is the largest oasis in Saudi Arabia, located about 40 miles west of the Persian Gulf. It spans approximately 12,000 hectares and is irrigated by over 60 artesian springs, supporting more than three million palm trees that yield various types of dates. The region, which derives its name from this central oasis, is bordered by Kuwait, the Persian Gulf, the Rubʿ al-Khali desert, and the Dahnā sand belt. Historically, Al-Hasa experienced periods of independence and Ottoman and Wahhābī control before becoming part of Saudi Arabia. The discovery of significant petroleum deposits in the 1930s transformed the region, making it a principal oil-producing area for the nation. The population is a mix of Sunni and Shiʿi Muslims, with a notable presence of expatriates working in the petroleum industry.123
