Abstract :

The Kopet-Dagh Basin in NE Iran contains the giant Khangiran and Gonbadii gasfields at which Upper Jurassic carbonates of the Mozduran Formation constitute the principal reservoir unit. The formation is composed mainly of limestone, dolostone, with minor interlayers of marl, sandstone and gypsum/anhydrite. Its lower and upper contact with the Middle Jurassic siliciclastics of the Kashafrud Formation and Lower Qetaceous siliciclastics of the Shurijeh Formation respectively, is disconformable. Recognition of seismic- terminations and facies led to the Mozduran carbonate platform evolution from a rimmed-shelf to carbonate ramp and understanding of to find at least one reason for drilled wells. The rapid lateral thickness and facies variations along with presence of paleohighs most likely are accompanied with the stratigraphic traps.
