“…In the field exploitation practice of shale oil, the area with high abundance of movable reserves in the sweet spot should be preferred for well location deployment. • Engineering factors: The application of rotary steering technology (Janwadkar et al, 2009;Yan et al, 2021;Al Amri et al, 2021) and element logging technology (Zhu et al, 2018;Zhang et al, 2021) has greatly improved the drilling rate of horizontal wells. Research shows that the foundation of high shale oil production is to make the horizontal section as much as possible in the reservoir, especially in the area with high reserves.…”
