The Oligo-Miocen Asmari Formation is the most important oil reservoir in Iran. This study deals with facies associations, sedimentary environments and sequence stratigraphy of this formation in Masjed-I-Solyman oil field by using petrographical studies and statistical analysis. These findings show that studied succession belongs to the upper Asmari Formation (Bordigalian) with nine microfacies assosiations that consist of four wackestone, four packstone and one Boundstone microfacies. These microfacies were deposited in the inner and middle parts of a homoclinal carbonate ramp. Sequence stratigraphy studies express that the succession could be discriminated to four third order sedimentary sequences that would have been deposited under global sea level fluctuation (Eustasy).
