FACTBOX-UAE oil and gas concessions

(Reuters) - Multinationals hold stakes in oil and gas concessions in the United Arab Emirates, the world's sixth-largest oil exporter.

Following are details of the three largest concessions, with output based on industry estimates.

Abu Dhabi Company for Onshore Oil Operations (ADCO)

Crude output around 1.4 million bpd. Capacity around 1.45-1.5 mln bpd.

Concession expires 2014.

ADCO operates onshore and in shallow coastal waters of the emirate of Abu Dhabi.

Oil output is mainly from five fields. Asab, Bab, Bu Hasa, Sahil and Shah. All fields are linked to the storage and shipping facilities located at Jabel Dhana, where tankers load Murban crude for export.

Oil production also comes from four other fields: Jarn Yaphoure, Al Dabbiya, Rumaitha and Shanayel.

The original concession agreement was signed in January 1939 with Petroleum Development (Trucial Coast). In 1962, the company became known as the Abu Dhabi Petroleum Company (ADPC), and in 1979, it became known as the ADCO.

BP (BP.L) 9.5 percent

Royal Dutch Shell (RDSa.L) 9.5 percent

Total (TOTF.PA) 9.5 percent

Exxon Mobil (XOM.N) 9.5 percent
