Omani oil production rolled over in 2001, and with the best research, exploration and EOR teams in the world (namely, Shell's), oil output has continued to fall.
EDIT
In geological terms, the Oman lies at the southern end of the Persian Gulf Province, but in addition to the same prolific Jurassic reservoirs as found in the Emirates, it also has Palaeozoic reservoirs, charged by Precambrian source-rocks. Cambrian salt also plays an important part in the structural development. Shell was one of the pioneers in the country, where drilling commenced in 1955. As many as 600 wildcats have now been drilled, finding three giant fields (Yibal, 1962, with 2 Gb; Fahud, 1964, with 1 Gb, and Marmul, 1957, with about 600 Mb), as well as a large number of generally small to moderately sized fields. They follow a northerly trend through the central parts of the country extending into the Emirates.
In total, about 14 Gb have been discovered, of which half has been produced. Future discovery is here estimated at about 250 Mb, although there are some hopes of that a new deepwater play may be identified. Discovery peaked in 1962 delivering a corresponding peak of production in 2001. Production is now set to decline at a depletion rate of about 4% a year from its present level of 822 kb/d to about 600 kb/d by 2010 and 400 kb/d by 2020. Information on local consumption is not available, but if it is about 50 kb/d, the Oman may remain a net exporter for many years to come. Gas reserves stand at about 42 Tcf , being consumed locally at about 320 Gcf a year, leaving ample supplies for the future. In short, the Omani are well provided for, and since their oil resources are both modest and in decline they do not form an obvious military target, unless control of the Gulf of Hormuz becomes a critical issue.
