  • Digital Drill Core Models: Structure-from-Motion as a Tool for the Characterisation, Orientation, and Digital Archiving of Drill Core Samples 
    Betlem, Peter; Birchall, Thomas; Ogata, Kei; Park, Joonsang; Skurtveit, Elin; Senger, Kim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Structure-from-motion (SfM) photogrammetry enables the cost-effective digital characterisation of seismic- to sub-decimetre-scale geoscientific samples. The technique is commonly used for the characterisation of outcrops, ...
  • Effect of brine-CO2 fracture flow on velocity and electrical resistivity of naturally fractured tight sandstones 
    Nooraiepour, Mohammad; Bohloli, Bahman; Park, Joonsang; Sauvin, Guillaume; Skurtveit, Elin; Mondol, Nazmul Haque (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Fracture networks inside geological CO2 storage reservoirs can serve as primary fluid flow conduit, particularly in low-permeability formations. While some experiments focused on the geophysical properties of brine- and ...
  • Induced-seismicity geomechanics for controlled CO2 storage in the North Sea (IGCCS) 
    Park, Joonsang; Griffiths, Luke; Dautriat, Jérémie; Grande, Lars; Vera Rodriguez, Ismael; Iranpour, Kamran; Bjørnarå, Tore Ingvald; Marin-Moreno, Héctor; Mondol, Nazmul Haque; Sauvin, Guillaume; Sarout, Joel; Soldal, Magnus; Oye, Volker; Dewhurst, David N.; Choi, Jung Chan; Best, Angus Ian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The aim of the current study, IGCCS (2017–2020), is to evaluate the feasibility of micro-seismic (MS) monitoring of CO2 injection into representative storage candidates in the North Sea, based on broad and quantitative ...
  • Inferring microseismic source mechanisms and in situ stresses during triaxial deformation of a North-Sea-analogue sandstone 
    Griffiths, Luke; Dautriat, Jérémie; Rodriguez, Ismael A Vera; Iranpour, Kamran; Sauvin, Guillaume; Park, Joonsang; Sarout, Joel; Soldal, Magnus; Grande, Lars; Oye, Volker; Dewhurst, David; Mondol, MD Nazmul Haque; Choi, Jung Chan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Monitoring microseismic activity provides a window through which to observe reservoir deformation during hydrocarbon and geothermal energy production, or CO2 injection and storage. Specifically, microseismic monitoring may ...
