Abstract More than 4,000 sandstone-hosted uranium occurrences host over 1.2 billion
pounds of mined and in situ U 3 O 8 throughout the Colorado Plateau. Most of the resources …

Abstract The Lower Cretaceous Quantou Formation in the southern Songliao Basin is the
typical tight oil sandstone in China. For effective exploration, appraisal and production from …

In order to better predict the petrophysical properties of the tight sandstone reservoirs in the
Upper Triassic Yanchang Formation, Ordos Basin, China, the nature of the diagenetic …

Authigenic clays and calcite cements are important in the development of reservoir tightness
and the formation of hydrocarbon sweet spots. We investigated Jurassic low-permeability …

The sandstone units of the Early Cretaceous Lower Goru Formation are significant reservoir
for gas, oil, and condensates in the Lower Indus Basin of Pakistan. Even though these …

Heterogeneity is an essential feature of tight sandstones because it is directly related to
reservoir quality. The Upper Triassic Xujiahe Formation in the Sichuan Basin was used as a …

Quartz grains and their microstructural characteristics are essential both to the formation of
interparticle porosity and to the influencing reservoir brittleness of siliceous shale. Here we …

The tight sandstones of the Cretaceous Quantou formation are the main exploration target
for hydrocarbons in the southern Songliao basin. Authigenic quartz is a significant …

Porosity evolution history, hydrocarbon charging periods, diagenetic and reservoir-forming
characteristics of low-permeability and tight sandstone are presented in this study. The …

Oil accumulation, being difficult and complicated, is an important issue in petroleum
exploration researches. Authigenic minerals, such as carbonate cements and chlorite, can in …
