This article reviews the mechanisms of shale gas storage and discusses the major risks or
uncertainties for shale gas exploration in China. At a given temperature and pressure, the …

Catalytic upgrading of methane in natural gas and/or shale gas via oxidative methane
coupling (OMC) is an important option tailored by industry for meeting the global ethylene …

There remains a lack of understanding of environmental isotopes and their use; students
and practitioners typically find the concepts of isotope concentrations and partitioning to be …

The marine shale of the Silurian Longmaxi Formation in southern Sichuan Basin, China is
characterized by its huge thickness (100–600 m), high TOC values (0.35–18.4%), favorable …

Shale-gas resource plays can be distinguished by gas type and system characteristics. The
Newark East gas field, located in the Fort Worth Basin, Texas, is defined by thermogenic gas …

Unconventional natural gas extraction from tight sandstones, shales, and some coal‐beds is
typically accomplished by horizontal drilling and hydraulic fracturing that is necessary for …

Microbial methane accumulations have been discovered in multiple coal-bearing basins
over the past two decades. Such discoveries were originally based on unique biogenic …

Coal bed and shale gas can be of thermogenic, microbial or of mixed origin with the
distinction made primarily on the basis of the molecular and stable isotope compositions of …

Organic petrology developed as coal petrology at the beginning of the 20th century
dedicated mainly to the study of coals because of their utilization in industry. Coal petrology …

Shale with high quartz, feldspar and carbonate, will have low Poisson's ratio, high Young's
modulus and high brittleness. As a result, the shale is conducive to produce natural and …
