Diagenetic controls on reservoir quality and heterogeneity of eocene red-bed sandstones: a case study from the Shahejie Formation, southern Bohai Bay basin, China
The lower sub-member of the fourth member of the Eocene Shahejie Formation (LSm-ESF) in the southern Bohai Bay Basin hosts red-bed sandstones that are increasingly targeted as deep hydrocarbon reservoirs, yet the quantitative controls of diagenesis on their reservoir quality remain poorly constrained below 3000 m.
