The Asmari Formation is a thick carbonate-terrigenous succession in the Zagros Foreland Basin  deposited during the Oligocene–Early Miocene ages. The Stratigraphic forward modeling is n used in this study to determine the sediment supply, transportation parameters, and production rate of the Asmari Formation during precipitation in the Abadan Plain. The Dionisos Flow software is used for modeling studied depositional sequences. Argillaceous limestones, sandy dolostones, sandy limestones, sandy shales, limestones, sandstones, and shales are the main lithology of the Asmari Formation in studied wells. Also, the studied formation consists of four to five depositional sequences in the studied wells. The sedimentary environment of the Asmari Formation in the selected wells includes the inner to outer ramp (hemipelagic and pelagic deposits). The input parameters to the software for modeling include gamma log data, global sea-level curve, thickness and bathymetry maps, as well as sedimentary facies. Examination of the calculated data shows that the wave energy and water flow rate are effective factors in the sediment transportation and change in the sedimentation process of the region. The highest rate of carbonate production is estimated in the transgressive system tract of the second depositional sequence of studied wells in the inner ramp environment.
