Machine learning enhanced data assimilation framework for multiscale carbonate rock characterization
Zhenkai Bo, Ahmed H. Elsheikh, Hannah P. Menke +5
Carbonate reservoirs offer significant capacity for subsurface carbon storage, oil production, and underground hydrogen storage. X-ray computed tomography (X-ray CT) coupled with n…
Beyond Critical Minerals Targets: Digital Rock Physics as Infrastructure for Secure and Circular Supply Chains
Hannah P. Menke, Alessio Scanziani, Maja Rücker
The United Kingdom and Europe are moving rapidly from critical minerals target-setting to implementation. The EU Critical Raw Materials Act and the UK's Vision 2035 create ambitiou…
A First Look at Hydrogen Generation in an Ultramafic Rock with Micro-CT and SEM-BEX
Hannah P. Menke, Zaid Z. Jangda, Max Webb +2
Natural hydrogen generated by water-rock interaction in ultramafic rocks is increasingly recognised as a potentially important primary energy resource, but the pore-scale processes…
Inference of microporosity phase properties in heterogeneous carbonate rock with data assimilation techniques
Zhenkai Bo, Ahmed H. Elsheikh, Hannah P. Menke +3
Accurate digital rock modeling of carbonate rocks is limited by the difficulty in acquiring morphological information on small-scale pore structures. Defined as microporosity phase…
Enhanced Permeability Estimation in Microporous Rocks Using a Hybrid Macropore-Darcy Approach
Dmytro Petrovskyy, Julien Maes, Hannah P. Menke +5
This study presents a novel workflow for constructing hybrid macropore-Darcy models from micro-CT images of microporous rocks. In our approach, macropore networks are extracted usi…
