This study analyzes the pore systems of the Majiagou carbonate reservoirs, Ordos Basin, China. The occurrence of small and large pores results in a heterogeneous pore distribution and a high fractal dimension. Reservoir quality increases with the degree of complexity of the microscopic pore structure.

Using generated, retained, and expelled amounts of hydrocarbons during maturation in the Yanchang Formation, Ordos Basin, the authors calculate expulsion efficiency of individual n-alkanes. With inorganic and organic controls, a hydrocarbon generation-retention-expulsion model is developed.

A new mathematical model is proposed to calculate the horizontal principal stresses in the context of fault-related folds. The southwest Qaidam Basin, China, is used as a case study to validate the proposed mathematical model.

The purpose of this paper is to investigate the diagenetic process of sandstones from the Upper Paleozoic, Linxing area, Ordos Basin, China, to evaluate the factors controlling compaction, cementation, and dissolution that affect reservoir quality, and to reconstruct the diagenetic history of the region.

Natural fractures are important storage spaces and fluid-flow channels in tight-oil sandstones. Intraformational open fractures are the major channels for fluid flow in tight-oil sandstones. Small faults may provide fluid-flow channels across different layers.

Calcite cementation has been identified as an active process in the Upper Triassic Yanchang Formation throughout its burial history and as a major diagenetic factor causing strong reservoir heterogeneities.

Using recently acquired three-dimensional seismic data, we summarize typical patterns for seismic-based identification and stage analysis of sedimentary units in the Eocene succession of the southern slope-break belts of the Bozhong sag, Bohai Bay Basin, China.
