Conglomerate categories in coarse-grained deltas and their controls on hydrocarbon reservoir distribution: a case study of the Triassic Baikouquan Formation, Mahu Depression, NW China
Organic geochemistry and oil-generating potential of the Oligocene–Early Miocene Dingqinghu Formation sediments in the Lunpola Basin, Tibet
Geological controls and methane sorption capacity of marine shales of the Fuling shale gas field in the eastern Sichuan Basin, China
The Chang 7-1 sandstone members of the Triassic Yanchang Group in the Longdong region of the SW Ordos Basin are typical ultra-low-permeability reservoirs which are studied in detail in Tan et al. (2017 Petroleum Geoscience, 23, 454–465). This SEM image taken from a core sample in the Chang 7-1 section illustrates grain coating and pore-throat blockage by iron, calcite and dolomite cementation, which reduces both porosity and permeability.
