Analysis of Factors Controlling Shale Gas Enrichment
In this chapter, the definition of shale gas is reinterpreted and proposed: Shale gas is the “residual gas” in source rock that has not been...
-
Nutrient enrichment driven by canopy rainfall redistribution: Mechanism, quantification, and pattern
Vegetation canopies intercept and redistribute rainfall into throughfall and stemflow, which transfer substantial amounts of elements into the soil,...

Main controlling factors and enrichment model of a multi-layer tight sandstone gas reservoir: case study from the Linxing Gas Field, eastern Ordos Basin, Northern China
Determining the main controlling factors and the enrichment model of a tight sandstone gas (TSG) accumulation remains a key challenge in natural gas...

Nitrogen enrichment enhances thermal acclimation of soil microbial respiration
As the climate warms, the feedback between soil carbon (C) and climate can decrease in magnitude over time due to the thermal acclimation of...

The abundance, distribution, and enrichment mechanism of harmful trace elements in coals from Guizhou, Southwestern China
Coal seams can enrich a variety of harmful trace elements under specific geological conditions. The spatial distribution of harmful trace elements in...

Enrichment of Gold Above Background
Enrichment of an element above its average abundance in the Earth’s crust is required to form any ore deposit. For gold, that enrichment is around...

Constraints of palaeoenvironment on organic matter of Benxi Formation shale and discussion on enrichment mechanism under different facies
As a hydrocarbon-rich sedimentary basin in China, the Ordos Basin has enormous potential for shale gas resources. The shale of the Upper...
