The Effect of Strike-Slip Faults on Hydrocarbon Traps in the Fars Region: a Study of Hendurabi Fault

The Zagros fold-thrust belt's Fars region is crucial for the placement of enormous gas reserves in Permo-Triassic carbonate sediments. Therefore, it's important to investigate the potential impact of the Hendurabi fault on the expansion of hydrocarbon traps in the inner Fars region. This will help advance the exploration goals of hydrocarbon materials. The study area is located in the inner Fars region of the Zagros thrust belt. In this research, maps of equal thickness have been prepared, analyzed, and evaluated based on drilling well data in the region, using ArcGIS software. Given the importance of changes and evolutions of the hydrocarbon system in the exploration of hydrocarbon resources, the function of the main basement faults with the role of controlling the bottom of the sedimentary basins, along with the changes that have occurred, can change the nature of a hydrocarbon system and the created hydrocarbon traps. Overall, the activity of the Hendurabi fault has caused thickness changes on the sides of the fault, confirmed by the uplifts and subsidence’s created on the sides of the Hendurabi fault at the same time as the deposition of some formations such as Dashtak. The activity of this fault as a controlling fault of the sedimentary basin floor during the sedimentation of formations like Dashtak is confirmed. Based on the obtained results, the southeastern area of the studied area, containing hydrocarbon traps, is suitable for exploration due to the adequate and appropriate thickness and suitable depth of the Kangan reservoir horizon and Dashtak caprock.
