An integrated workflow to characterize lower Eagle Ford shale for hydrocarbon gas huff-n-puff simulation

Huff-n-puff (HnP) gas injection has proven to be effective for recovering more liquid hydrocarbons from shale oil reservoirs. However, effective simulation of HnP requires a better understanding of the complex microstructure of shales and the multi-scale pore systems. An integrated workflow is developed that identifies multicomponent grains and pores types in the Lower Eagle Ford (LEF) shale at different depths, and distinguishes depositional...
