Saudi Arabia’s Ghawar Field

Among the many prolific oil fields in the Middle East, the giant Ghawar field in Saudi Arabia stands out as the crown jewel.

Discovered in 1948, Ghawar is the world’s biggest oil field, stretching 174 miles in length and 16 miles across to encompass 1.3 million acres.

Current estimates, according to the numerous published articles and reports on Ghawar, tag cumulative oil production from this geological giant at 55 billion barrels, and the field just keeps going gangbusters. Average production for the last 10 years has held essentially steady at five million barrels per day.
