The Asmari oil fields of Iran are truly giants, most of them having recoverable reserves greater than 1 billion bbl, in many fields much more than that. The individual accumulations occupy very large rock volumes in large- amplitude folds and, although the reservoir properties of the Asmari are poor in terms of porosity and matrix permeability, very high production rates are possible because of extensive reservoir fracturing. These rates can be maintained for very long periods because of the great vertical extent of the oil columns. The Asmari fields are prime examples of anticlinal traps and of the effect of fracturing on reservoir performance. The Asmari reservoir is a limestone of Oligo-Miocene age and consists mostly of shallow-water but non-reefal carbonates with a significant sandstone member developing the NW. part of the area. The Asmari is the uppermost wholly marine unit in a sequence of shelf carbonates interspersed with shale which was deposited, with only minor interruptions, from Carboniferous through Oligo-Miocene time.
