IPC created an associate company, Petroleum Development (Oman and Dhofar) Ltd, to operate the concession. The company had the same five shareholders as IPC, four of which had an interest of 23.75%: the Royal Dutch/Shell Group, the Anglo-Persian Company (which would eventually become the British Petroleum Company, or BP), Compagnie Française des Pétroles (a predecessor of today's Total) and the Near East Development Company (whose shareholders were Standard Oil of New Jersey and Socony-Vacuum, today's ExxonMobil), and the remaining 5% stake being held by the fifth shareholder, Partex, representing the interests of the oil magnate, Calouste Gulbenkian.
