Abu Dhabi Oil Company Ltd. (Japan), ADOC is a subsidiary of Cosmo Oil Company Ltd. Abu Dhabi Oil Co., Ltd. (Japan), (ADOC), was established with a capital of 600 million yen, equally subscribed to by the three companies. In September 1969, the exploratory well No.1 successfully produced the long-awaited crude oil. This underground structure was given the name of Mubarraz Oil Field, and was the first step towards ADOC's success in Abu Dhabi. Although the United Arab Emirates, (UAE), was founded on 2nd December, 1971, ADOC had advanced into this area before the nation came into existence. In May 1973, the production of oil began, and in June 1973, the first shipment of Mubarraz crude oil left for Japan.
