Economics of geological CO2 storage and leakage [PDF]

open access: yesClimatic Change, 2009
The economics of CO2 capture and storage in relation to the possibility of leakage of CO2 from geological reservoirs once this greenhouse gas has been stored artificially underground will be among the main determinants of whether CCS can significantly contribute to a deep cut in global CO2 emissions.

In-situ rock tests for fault gouge zone:A case in Fengman hydropower station, China [PDF]

open access: yesE3S Web of Conferences, 2021
The existence of faults in the dam site area threatens the stability and safety of large-scale hydropower projects in China. The fault argillaceous zone is the worst kind of fault fracture zone, and the determination of its deformation and strength ...

Distributed Fiber Optic Strain Sensing for Geomechanical Monitoring: Insights from Field Measurements of Ground Surface Deformation

open access: yesGeosciences, 2021
In recent years, distributed fiber optic strain sensing (DFOSS) technology has demonstrated a solution for continuous deformation monitoring from subsurface to surface along the wellbore. In this study, we installed a single-mode optical fiber cable in a

Case study on amplitude and phase response comparison between DAS and 3C geophone VSP surveys at a test site in Japan

open access: yesFrontiers in Earth Science, 2022
Distributed acoustic sensing (DAS) is an effective tool for seismic surveys and is widely used as the preferred sensor for acquiring dense Vertical Seismic Profile (VSP).

Implications of Simulation of CO2 Dispersion on Marine Potential Environmental Impact Assessment and Monitoring at CO2 Storage Sites

open access: yesJournal of Water and Environment Technology, 2023
When carbon dioxide (CO2) is stored in sub-seabed geological formations, the environmental impact assessment assuming CO2 leakage and monitoring CO2 concentration in the sea are mandatory in Japan.

Stratigraphy of the Upper Jurassic to lowermost Cretaceous in the Rødryggen-1 and Brorson Halvø-1 boreholes, Wollaston Forland, North-East Greenland

open access: yesGEUS Bulletin, 2023
Two shallow cores drilled in northern Wollaston Forland, North-East Greenland, provide a combined section covering the upper Kimmeridgian (Upper Jurassic) – Barremian (Lower Cretaceous) and comprising the Bernbjerg, Lindemans Bugt, Palnatokes Bjerg and ...

In situ hydromechanical responses during well drilling recorded by fiber-optic distributed strain sensing [PDF]

open access: yesSolid Earth, 2020
Drilling fluid infiltration during well drilling may induce pore pressure and strain perturbations in neighbored reservoir formations. In this study, we report that such small strain changes (∼20 µε) have been in situ monitored using fiber-optic ...

Enabling onshore CO2 storage in Europe: fostering international cooperation around pilot and test sites [PDF]

open access: yes, 2016
To meet the ambitious EC target of an 80% reduction in greenhouse gas emissions by 2050, CO2 Capture and Storage (CCS) needs to move rapidly towards full scale implementation with geological storage solutions both on and offshore.
