High Quality Content by WIKIPEDIA articles! Ras Tanura is a city in the Eastern Province of Saudi Arabia located on a peninsula extending into the Persian Gulf. The name Ras Tanura applies both to a gated Saudi Aramco employee compound (also referred to as "Najmah") and to an industrial area further out on the peninsula that serves as a major oil port and oil operations center for Saudi Aramco, the largest oil company in the world. Today, the compound has about 3,200 residents, with a few Americans and British expats. Geographically, the Ras Tanura complex is located a distance south of the modern industrial port city of Jubail and north across Tarut Bay from the old port city of (Al-)Dammam.
