Hydrocarbon accumulation differences and exploration directions among sub-sags of the Taibei Sag, Tuha Basin, China
The Taibei Sag of the Tuha Basin contains three major hydrocarbon-generating sub-sags—Shengbei, Qiudong, and Xiaocaohu—in the Shuixigou Group. Although these sub-sags share similar tectonic–sequence–sedimentary evolutionary backgrounds, they exhibit distinct petroleum geological characteristics and…
