With the increasing interest in unconventional resource plays, there have been important
changes in the way how reservoirs and their attributes are assessed and characterized. Of …

Helium is an important, scarce, and strategic resource that is critical to national security and
advanced technology development. Although helium originates from mantle degassing and …

Maximum burial depth of the Permian Fengcheng Formation, which contains significant oil
resources in the Mahu Sag, exceeds 4500 m constituting a deep reservoir. Fractures are …

Water is ubiquitously present within organic-rich shale and can exert an important effect on
the gas-in-place and gas adsorption capacity of shale reservoirs. Thus, understanding the …

In complex geological areas, the chronology of tectonic fracture formation is pivotal for the
conservation and enhancement of shale gas reservoirs. These fractures, evolving over …

Lacustrine shale oil reservoirs of the Fengcheng Formation in the Mahu Sag, Junggar Bain,
NW China contain abundant oil resources, with the highest daily oil production of a single …

This study examines the mechanisms that most influenced the accumulation of shale gas
deposits of the Lower Cambrian Niutitang, Upper Ordovician Wufeng, and Lower Silurian …

The increasing complexity of reservoirs, particularly shale reservoirs, demands accurate
information on the formation composition, mineralogy, and mechanical parameters for …

To gain a better understanding of the gas-bearing property of Lower Cambrian Niutitang
Formation shale and its influencing factors, the shale gas-bearing conditions, gas content …

Fractures not only control the distribution of oil and gas reservoirs, but also are key points in
the research of oil and gas reservoir development programmes. The tectonic fractures in the …
