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

Solid 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 ...

Mudstone diagenesis and sandstone provenance in an Upper Jurassic – Lower Cretaceous evolving half-graben system, Wollaston Forland, North-East Greenland

GEUS Bulletin, 2023
The influence of rifting on the composition of Kimmeridgian to Barremian mudstones from northern Wollaston Forland, North-East Greenland is investigated by petrographic and mineralogical analyses of the Brorson Halvø-1 and Rødryggen-1 cores, and ...

Social Acceptance of CCS

Journal of MMIJ, 2020
In this review, the status quo of social acceptance of CCS is discussed in relation with international efforts to establish understanding on CCS. The author analyzed suspended 43 CCS project cases out of total 133 cases, and identified major impacting ...

Integrity management system for geological body of salt-cavern gas storage

You-qi chuyun, 2022
The geological body management of gas storage is essential for the integrity management of Underground Gas Storage (UGS). However, the integrity management of geological body of gas storage is unclear in concept with fuzzy interface and incomplete system

Organic geochemistry of an Upper Jurassic – Lower Cretaceous mudstone succession in a narrow graben setting, Wollaston Forland Basin, North-East Greenland

GEUS Bulletin, 2023
The Oxfordian–Ryazanian was a period of widespread deposition of marine organic-rich mudstones in basins formed during the early phases of the rifting that heralded the formation of the present-day North Atlantic.

Fiber Optic Sensing for Geomechanical Monitoring: (2)- Distributed Strain Measurements at a Pumping Test and Geomechanical Modeling of Deformation of Reservoir Rocks

Applied Sciences, 2019
In this study distributed fiber optic sensing has been used to measure strain along a vertical well of a depth of 300 m during a pumping test. The observed strain data has been used in geomechanical simulation, in which a combined analytical and ...

Geological Conditions and Suitability Evaluation for CO₂ Geological Storage in Deep Saline Aquifers of the Beibu Gulf Basin (South China)

Energies, 2023
The geological storage of carbon dioxide (CO2) is the most suitable option to achieve a large-scale and low-cost CO2 emissions worldwide, but the selection of favorable areas for the geological storage is the main issue.

Potential of the Middle Cambrian Aquifer for Carbon Dioxide Storage in the Baltic States

Energies, 2021
The importance of CO2 removal from the atmosphere has long been an essential topic due to climate change. In this paper, the authors aim to demonstrate the suitability of the underground reservoirs for CO2 storage based on their geological ...

A preliminary assessment of geological CO2 storage in the Khorat Plateau, Thailand

Frontiers in Energy Research, 2022
The main carbon dioxide (CO2) emissions in Thailand come from the energy sector. Gas-based power plants, including natural gas and biogas, are CO2 point sources, and are mostly located in the Khorat Plateau. Geological CO2 storage is an important element

Mesoscale Assessment of CO2 Storage Potential and Geological Suitability for Target Area Selection in the Sichuan Basin

Geofluids, 2017
In China, south of the Yangtze River, there are a large number of carbon sources, while the Sichuan Basin is the largest sedimentary basin; it makes sense to select the targets for CO2 geological storage (CGUS) early demonstration.
