Investigation of basin subsidence and sedimentation rate in Aghajari oil field

Sedimentation rate is dependent on different factors in sedimentary basins, that capable us to discriminate the geological conditions in the past by study of these rates. In this study subsidence and sediment accumulation rates were investigated using data obtained from well Aghajari-140 (Aj-140). By means of Genex basin modeling software burial history was reconstructed. Un-corrected sedimentation, total sedimentation and subsidence rate profiles are obtained for drilled formations in Aghajari-140 well to analysis the sedimentation and subsidence condition.Burial history plot reveal that Kazhdumi Formation as a source rock has been reached oil generation window in Miocene (15 Ma), but it is not entered gas window yet. Review of subsidence and sedimentation rates indicate two significant growing during deposition of Sarvak Formation in the upper Cretaceous and Asmari, Gachsaran and Mishan formations between Oligocene to Holocene period.
