محدودیت های زمین شناختی برای اهداف هیدروکربن در احداث دزفول، بند زاگرس و رانش، سوئیس

Understanding of reservoir architecture is one of the most important steps in the petroleum exploration programs. New 2D/3D seismic data provided important insights into the tectonic evolution of the Dalpari prospect within the Dezful Embayment of the Zagros Fold and Thrust Belt, SW Iran. This hydrocarbon target has formed as a result of a transpressive dextral strike-slip fault activity mechanically interacting with reverse faults, out of the syncline thrusts and four orders of folds. In the northern part of the target, the existence of growth strata within the competent units of Gachsaran and Agha Jari Formations (i.e. Upper Miocene and Pliocene) helped to determine the time of the structural evolution of the hydrocarbon target. Finally, the existence of the incompetent strata (e.g. Gachsaran Formation and the Kalhur member of Asmari Formation) mechanically controlled the formation history of the Dalpari prospect. In a regional context, this architecture denotes local Zagros partitioning of the oblique convergence between the Afro-Arabian and Central-Iranian plates a problem that has been addressed by many other researchers in the past using.
