Multiscale Heterogeneity and Pore–Throat Controls on Upper Paleozoic Tight Sandstone Reservoir Quality in the Northern Yanchang Gas Field

Reservoir evaluation in the northern Yanchang Gas Field is complicated by variable permeability within low-porosity Upper Paleozoic sandstones. This study compares the He 8, Shan 1, Shan 2, and Benxi intervals using core petrophysical summaries, formation- and well-level heteroge...
