Noble gases within the crust originate from three main sources: the atmosphere, introduced
into the crust dissolved in groundwater; the mantle, in regions of magmatic activity; and …

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 …

Helium, nitrogen and hydrogen are continually generated within the deep continental
crust,,,,,,,–. Conceptual degassing models for quiescent continental crust are dominated by …

We detail here the general concepts behind using noble gases as a tracer of crustal fluid
processes and illustrate these concepts with examples applied to oil-gas-groundwater …

Injecting CO2 into deep geological strata is proposed as a safe and economically favourable
means of storing CO2 captured from industrial point sources,,. It is difficult, however, to …

Commercial helium systems have been found to date as a serendipitous by-product of
petroleum exploration. There are nevertheless significant differences in the source and …

Owing to the characteristics of chemical inertness, low molecular weight, low boiling point,
strong permeability and high heat conductivity, helium is extensively used in the fields of …

Helium gas is a scarce but important strategic resource, which is usually associated with
natural gas. Presently, only one extra-large helium-rich gas field has been found in China …

Petroleum Geoscience, 2nd edition is a comprehensive introduction to the application of
geology and geophysics to the search for and production of oil and gas. The aim this …

Based on the methodology for petroleum systems and through the anatomy and
geochemical study of typical helium-rich gas fields, the geological conditions, genesis …
