The Burgan field is an oil field situated in the desert of southeastern Kuwait. Burgan field can also refer to the Greater Burgan—a group of three closely spaced fields, which includes, in addition to Burgan field, the much smaller Magwa and Ahmadi fields. Greater Burgan is the world's largest sandstone oil field, and the second-largest overall, after Ghawar in Saudi Arabia. The Burgan field is located on the coast of the Persian Gulf, which played a huge part in the creation of this prominent reservoir formation many million years ago.
