Reservoir Pore Characteristics Based on Depositional Microfacies Control in the Neogene Guantao Formation, Bohai Bay Basin, China

open access: yesEnergies, 2022
The Neogene Guantao Formation Reservoir in the PLOilfield is a unconsolidated sandstone with high porosity and high permeability. The reservoir diagenesis is weak and dominated by compaction diagenesis.
