Caprock self-sealing effect due to CO2 leakage from geologic carbon sequestration reservoirs: a case study at Ping’an, China

open access: yesFrontiers in Energy Research, 2022
As a bottom technology for CO2 reduction, geological CO2 storage has attracted great attention from geologists, but there are few reports on the research of the caprock self-sealing effect due to CO2 leakage.

Relating in situ hydraulic conductivity, particle size and relative density of superficial deposits in a heterogeneous catchment [PDF]

open access: yes, 2012
Estimating the permeability of superficial deposits is fundamental to many aspects of catchment science, but can be problematic where insufficient in situ measurements are available from pumping tests in piezometers.
