Pore morphology in thermally-treated shales and its implication on CO₂ storage applications: A gas sorption, SEM, and small-angle scattering study

A combination of high-resolution imaging, low-pressure gas adsorption, and small-angle X-ray and neutron scattering quantifies changes in the pore characteristics of pulverized shale samples under oxic and anoxic environments up to 300 ℃. Clay-rich early-mature shales have a fair potential to generate hydrocarbons, the total organic carbon...

Optimal source-sink matching and prospective hub-cluster configurations for CO2 capture and storage in India

At COP-26, India announced strong climate commitments of reaching net-zero greenhouse gas emissions by 2070. Meeting this target would likely require substantial deployment of CO2 capture and storage (CCS) to decarbonize existing large point sources of CO2. This study attempts to evaluate opportunities for deployment of CCS in India in the...

Impact of Supercritical CO₂on Shale Reservoirs and Its Implication for CO₂Sequestration

Hydraulic fracturing has transformed the international energy landscape by becoming the go-to method for the exploitation of natural gas from unconventional shale reservoirs. However, in the recent years, the search for an alternative method of shale-gas exploration has intensified, because of various problems (e.g., contamination of ground...
