An accurate and reliable description of the porosity-permeability relationship in geological materials is valuable understanding subsurface fluid movement. This important for reservoir characterisation, energy exploitation, carbon storage (GCS) groundwater contamination remediation. Whilst between pore characteristics porosity permeability are well examined, further investigation into influence grain on would be beneficial due to inherent grains pores. work aims determine whether...

Abstract Mineral trapping (MT)is the most secure method of sequestering carbon for geologically significant periods time. The processes behind MT fundamentally occur at pore scale, therefore understanding which factors control this scale is crucial.

Perception of the driving environment is critical for collision avoidance and route planning to ensure safety. Cooperative perception has been widely studied as an effective approach addressing shortcomings single-vehicle perception. However, practical limitations vehicle-to-vehicle (V2V) communications have not adequately investigated. In particular, current cooperative fusion models rely on supervised do address dynamic performance degradation caused by arbitrary channel impairments. this...

The growing importance of subsurface carbon storage for tackling anthropogenic emissions requires new ideas to improve the rate and cost capture (CCS) project development implementation. We assessed sandstones from UK Geoenergy Observatories (UKGEOS) site in Glasgow, Wilmslow Sandstone Formation (WSF) Cumbria, at pore scale indicate suitability further assessment as CCS reservoirs. measured porosity, permeability other geometry characteristics using digital rock physics techniques on...

Abstract Subsurface sandstone deposits represent globally ubiquitous reservoirs which can potentially provide the characteristics necessary for effective geological storage of CO 2 . Geological carbon is widely agreed to be a key asset in tackling anthropogenic emissions and climate change reach sustainable ‘net zero’, despite present financial challenges associated with it. Therefore, improved understanding materials we plan store many gigatons critical. Developing cheaper characterisation...

Cooperative perception has been widely used in autonomous driving to alleviate the inherent limitation of single automated vehicle perception. To enable cooperation, vehicle-to-vehicle (V2V) communication plays an indispensable role. This work analyzes performance cooperative accounting for communications channel impairments. Different fusion methods and impairments are evaluated. A new late scheme is proposed leverage robustness intermediate features. In order compress data size incurred by...

We study carbon capture and sequestration (CCS) over time scales of 2000 years by implementing a numerical model reactive infiltration instability caused porous flow. Our focuses on the mineralization CO 2 dissolved in pore water—the geological phase CCS operation—starting 10–100 after injection subsurface. test influence three parameters: porosity, mass fraction Ca-rich feldspar mineral anorthite solid, chemical reaction rate, mode fluid flow efficiency CaCO 3 precipitation during...

This paper presents an overview of using X-ray micro computed tomography (μCT) as a valuable tool for scale investigation siliciclastic materials. When processed digital image analysis (DIA), quantitative data can be extracted from μCT 3D images. Subsurface reservoirs are great importance to society fluid-bearing formations, but also storage carbon dioxide. imaging has the capability perform preliminary, highly detailed investigations potential reservoirs. approach range benefits when...

Abstract The growing importance of subsurface carbon storage for tackling emissions requires an accurate characterization potential reservoirs to understand their capabilities. In this context, the use legacy data originally acquired in last fifty years scientific projects and petroleum exploration production activities would represent a suitable cost-effective solution help maximize value extended national asset. Core material represents only direct observation deposits must be preserved...
