tained an offshore concession which was then transferred to a company created to operate the concession: Abu Dhabi Marine Areas (ADMA) was a joint venture between BP and Compagnie Française des Pétroles (later Total). In 1958, using a marine drilling platform, the ADMA Enterprise, oil was struck in the Umm Shaif field at a depth of about 8,755 feet (2,669 m). This was followed in 1959 by PDTC’s onshore discovery well at Murban No.3.
In 1962, the company discovered the Bu Hasa field and ADMA followed in 1965 with the discovery of the Zakum offshore field. Today, in addition to the oil fields mentioned, the main producing fields onshore are Asab, Sahil and Shah, and offshore are al-Bunduq, and Abu al-Bukhoosh
