The tight sandstones are characterized by low porosity, low permeability, complex pore
structure and strong heterogeneity due to the extensive diagenetic modifications they …

The lacustrine mixed rocks, which are composed of detrital, carbonate, and volcanic
materials, have increasingly attracted attention due to their association with significant oil …

Determining the distribution and properties of multi-scale pores and the effect of these pores
on reservoir properties is very significant for the analysis of the factors controlling pore …

diagenetic alteration in the upper Paleozoic Benxi–Taiyuan, Shanxi, and Xiashihezi …

Abstract The Upper Triassic deep-lacustrine sedimentary gravity flow sandstones
(Yanchang Formation, Southern Ordos Basin) form an important oil reservoir, however, it is …

Accurate characterization of shale samples is of great importance for predicting and
evaluating their intrinsic properties as they undergo various geological processes. As such …

Reservoir studies in the Sandakan sub-basin NW Borneo are challenging and inexplicable
due to complex diagenetic effects such as compaction, cementation, dissolution and …

Clay coats are widespread in the Oligocene braided river channel sandstones in the Xihu
Depression on the East China Sea Shelf Basin. High clay coat coverage in braided channel …

A varying abundance of carbonate-bearing fluorapatite (CFA) nodules in Eocene lacustrine
shale in the Bohai Bay Basin was observed; however, mineralogical and geochemical …

Due to the limitations of pore throat characterization techniques, in-depth studies on the
