Estimated Ultimate Recovery(EUR)is a key criteria for oil production capacity and resource potential assessment. Besides drilling, completion and stimulation methods, geological elements also have influence on EUR. Shelly limestone of the Jurassic Daanzhai formation is light tight oil bearing reservoir in central of the Sichuan Basin, China. The reservoir is extremely tight with porosity below 2% and permeability below 0.1 millidarcy. Many researchers consider the shelly limestone is fractured reservoir because of its poor physical properties. This study takes Daanzhai formation as a case,the aim is to find the link between geological elements and their corresponding EUR.
