ABSTRACT: 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).
