Abstract:

Folding is a geological process in which the rock layers of the earth's crust are bent and deformed under enormous tectonic pressures, without significant fracture occurring. This phenomenon usually occurs as a result of the movement of tectonic plates and creates structures such as mountains, valleys, and domes. Folding shows the flexibility of rocks in certain conditions and tells a part of the history of the earth's evolution. Folding causes the formation of anticlines that can form good oil reservoirs. But folds, like faults, can cause hydrocarbon migration. Understanding the geometry and pattern of folds in thrust belts is an important part of the knowledge required in the exploration of hydrocarbon reserves. In addition, understanding the geometry and pattern of folds helps to better understand the physical aspects of reservoirs and provides a basis for advancing in other fields of reservoir studies. In this paper, the role of geological folds in oil and gas reservoirs will be discussed.
