"BP was incorporated in London in 1954 as a holding company called Iranian Oil Participants Ltd (IOP).[41][42] The founding members of IOP included British Petroleum (40%), Gulf Oil (8%), Royal Dutch Shell (14%), and Compagnie Française des Pétroles (now TotalEnergies SE, 6%). The four Aramco partners — Standard Oil of California (SoCal, later Chevron), Standard Oil of New Jersey (later Exxon), Standard Oil Co. of New York (later Mobil), and Texaco – each held an 8% stake in the holding company.[41][43] In addition, these companies paid Anglo-Iranian about $90 million for their 60 percent share in the consortium, and a further $500 million, paid out of a ten cent per barrel royalty. The Shah signed the agreement on 29 October 1954, and oil flowed from Abadan the next day. Within a few months each of the American companies contributed 1 percent to Iricon, a consortium made up of nine independent American companies, which included Phillips, Richfield, Standard of Ohio, and Ashland."
