Strong Reservoir Wettability Heterogeneities of an Eocene Tight Oil Play from the Bonan Sag, Bohai Bay Basin as Revealed by an Integrated Multiscale Wettability Evaluation

Strong Reservoir Wettability Heterogeneities of an Eocene Tight Oil Play from the Bonan Sag, Bohai Bay Basin as Revealed by an Integrated Multiscale Wettability Evaluation

Properly determining reservoir wettability is crucial for enhancing oil recovery and optimizing production strategies; this is particularly the case for tight oil reservoirs. The lower-fourth member of the Shahejie Formation (Es4x) in the Bonan Sag of the Bohai Bay Basin is a typical tight sandstone...
