Shale gas, although unconventional, is a prospective clean energy source. Shale gas
production is a complex multi-scale process with its spatial size ranging from the nanoscale …

Organic petrography via incident light microscopy has broad application to shale petroleum
systems, including delineation of thermal maturity windows and determination of organo …

In recent years CO 2 injection in shale has been investigated with aim to enhance shale gas
recovery (ESGR) and permanently sequester CO 2. This paper reviews the state of research …

To investigate the methane adsorption capacity and the characteristics of gas shales under
high pressures, we conducted total organic carbon (TOC), low-pressure nitrogen adsorption …

Shale matrix pore structure controls the gas storage mechanism and gas transport
behaviors. We employed various techniques to characterize the complex pore structures of …

Abstract Supercritical carbon dioxide (ScCO 2)-based fracturing technology associating with
CO 2 enhanced shale gas recovery is a promising technology to reduce the water …

A thorough study of the adsorption behavior of shales to methane (CH 4) and carbon dioxide
(CO 2) is critical for carbon dioxide sequestration in shale gas reservoirs and enhanced …

In shale reservoirs, the organic pores with various structures formed during the thermal
evolution of organic matter are the main storage site for adsorbed methane. However, in the …

This research article selects supercritical methane and organic-rich shale as adsorbate-
adsorbent pair to investigate methane adsorption behavior and enrich our understanding of …

Producing CH 4 from coal beds and shale reservoirs is an attractive unconventional energy
option. Injecting CO 2 into a coal or shale basin can extract more CH 4 and enable the …
