Company Profile

In the summer of 1967, the late ruler of Abu Dhabi, Sheikh Zayed Bin Sultan Al Nahyan (the former president of the United Arab Emirates), took the decisive step of allowing Japan to acquire oil concessions, which until then had been granted only to Western countries. Taking this opportunity, three Japanese independent oil-refining companies, Maruzen Oil Co., Ltd., Daikyo Oil Co., Ltd. (these two companies have since then merged into the present Cosmo Energy Holdings Co., Ltd.) and Nippon Mining Co., Ltd. (now JX Nippon Oil & Gas Exploration Corporation) took part in an international tender for a concession area relinquished by Abu Dhabi Marine Areas Ltd. (ADMA) and submitted the winning bid. On December 6 of the same year, an agreement concerning the exploration and development of the oil concession off the coast of Abu Dhabi was signed.

On January 17, 1968, 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 named the Mubarraz Oilfield, and we had taken the first step toward success in Abu Dhabi. Although the United Arab Emirates (UAE) was founded on December 2, 1971, we had advanced into this area before the nation came into existence. In May 1973, the long- awaited production of oil began, and in June 1973, the first shipment of Mubarraz crude oil left for Japan.

On April 28, 1979, ADOC entered into a supplementary agreement which granted ADOC a new concession in the West Mubarraz area, offshore Mubarraz Island.
Umm Al-Anbar Oil Field,(AR), and the Neewat Al-Ghalan Oil Field,(GA), of the new concession area, started oil production in 1989 and 1995,respectively. The crude oil produced from these two oil fields and the Mubarraz crude oil
oil is commingled together and the commingled oil was given the name of “Mubarrz Blend”, the entire production of which has been regularly shipped to Japan.

On February 3, 2011, ADOC signed a new concession Agreement with Abu Dhabi Supreme Petroleum Council to continue production of oil from the existing three oil fields after the expiry of the former Concession Agreement on December 6, 2012, for a period of 30 years together with the development of some structures of the Hail Field which is adjacent to Mubarraz Island.

The UAE, which came into being after we started oil development in Abu Dhabi, is one of the most economically advanced and politically stable countries in the Middle East. Since its foundation, the nation has achieved tremendous growth, under the wise and strong leadership of the late president Sheikh Zayed.

During this period, the UAE also attained remarkable growth in crude oil transactions with Japan, which now is relying on the UAE for more than 20-percent of its entire crude oil imports. Consequently, the two countries are enjoying unshakably strong relations with each other.

At ADOC, we have established over the years an elaborate optimal operation system in close cooperation with ADNOC. ADOC is highly regarded for its achievements in Abu Dhabi since its inception.

Based on this good reputation and Abu Dhabi’s unshakable trust in us, we will continue to exert strenuous efforts to enhance our production capacity and to perform oil operations efficiently, while always acting to protect the environment.
