  • Fluid expulsion and microfracturing during the pyrolysis of an organic rich shale 
    Panahi, Hamed; Kobchenko, Maya; Meakin, Paul; Dysthe, Dag Kristian; Renard, Francois (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    During progressive burial, low permeability organic-rich shale rocks evolve chemically and physically as the temperature and stress increase and organic matter matures. The transformation of organic matter into hydrocarbon, ...
  • In-situ imaging of fracture development during maturation of an organic-rich shale: Effects of heating rate and confinement 
    Panahi, Hamed; Kobchenko, Maya; Meakin, Paul; Dysthe, Dag Kristian; Renard, Francois (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The statistics and dynamics of fractures formed during the accelerated maturation of kerogen-rich shale was investigated by heating Green River Shale (R-8 unit, Piceance Basin, northwestern Colorado) core samples while 3D ...
  • Microfracturing during primary migration in shales 
    Teixeira, Marcello Goulart; Donze, Frederic; Renard, Francois; Panahi, Hamed; Papachristos, Efthymios; Scholtes, Luc (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    In several geological environments, chemical reactions are coupled to rock deformation and the associated stresses induced locally interact with the far field loading. This is the case in immature shales that undergo burial ...
