Abstract: 
The Asmari Formation (Oilgocene-Miocene), in the Ahwaz Oilfield, consists of sandstone, limestone, sandy limestone, dolomitic limestone and marl; the Ahwaz Sandstone Member can be identified within the Asmari Formation of this oilfield. Seven boreholes namely Az 11, Az 19, Az 20, Az 43, Az 45, Az 65, and Az 85, are selected in which to study temporal and facies relationship, rock accumulation rate, stratigraphic continuity/fault, and stratigraphic range of various microfossils of the Asmari Formation. Plotting stratigraphic data of other boreholes against that of Az 65, as the Standard Reference Section (SRS), it is obvious that basal and upper parts of the SRS are missing from other stratigraphic sections. Application of the Graphic Correlation Method also indicates the rate of rock accumulation has been slower in Az 11 and Az 45 compared to that of the SRS. In Az 19, the Line of Correlation (LOC) occurs in a channel testifying to complete stratigraphic range of microfossils in the Composite Standard Reference Section (CSRS).
