Bruna, P.B.R. (author), Bertotti, G. (author), Charton, R.J.G. (author), Dixon, R. (author), Nasri, A. (author)Southern Tunisia is known to be less deformed and simpler than its neighboring Atlassic domain to the north. This area is complex and basin evolution in the Southern Chotts-Jeffara (SCJ) basin is debated. In this paper we combined surface and subsurface data with low temperature thermochronology (LTT) to reinvestigate the tectono-sedimentary...journal article 2023

Bruna, P.B.R. (author), Bertotti, G. (author), Amor, Salma Ben (author), Nasri, Ahmed (author), Ouahchi, Sondes (author)The southern Chotts basin (SCB), Central Tunisia, has shown hydrocarbon potential since the end of the 1980s. This basin records a complex structural history which appears decoupled at the Hercynian or Variscan unconformity. The Paleozoic series is deformed by short to medium wavelength folds (kilometres-multi kilometres scale) and by steep...conference paper 2022

de Hoop, S. (author), Voskov, D.V. (author), Bertotti, G. (author), Barnhoorn, A. (author)Fracture networks are abundant in subsurface applications (e.g., geothermal energy production, CO<sub>2</sub> sequestration). Fractured reservoirs often have a very complex structure, making modeling flow and transport in such networks slow and unstable. Consequently, this limits our ability to perform uncertainty quantification and increases...journal article 2022

Prabhakaran, R. (author), Bertotti, G. (author), Urai, Janos (author), Smeulders, D.M.J. (author)Rock fractures organize as networks, exhibiting natural variation in their spatial arrangements. Therefore, identifying, quantifying, and comparing variations in spatial arrangements within network geometries are of interest when explicit fracture representations or discrete fracture network models are chosen to capture the influence of...journal article 2021

Wang, Y. (author), de Hoop, S. (author), Voskov, D.V. (author), Bruhn, D.F. (author), Bertotti, G. (author)Multiphase mass and heat transfer are ubiquitous in the subsurface within manifold applications. The presence of fractures over several scales and complex geometry magnifies the uncertainty of the heat transfer phenomena, which will significantly impact, or even dominate, the dynamic transport process. Capturing the details of fluid and heat...journal article 2021

(author)Diagnostic morphological features (e.g., rectilinear seafloor scarps) and lateral offsets of the Upper Quaternary deposits are used to infer active faults in offshore areas. Although they deform a significant seafloor region, the active faults are not necessarily capable of producing large earthquakes as they correspond to shallow structures...journal article 2021

de Hoop, S. (author), Voskov, D.V. (author), Bertotti, G. (author)Growing demand for cleaner energy sources has led to the comprehensive investigation of high-enthalpy carbonate reservoirs. These reservoirs are often chemically and mechanically altered and hence contain a large uncertainty in the spatial distribution of the reservoir parameters. The resulting discontinuity features commonly include complex...conference paper 2020

Fernández-Blanco, David (author), Mannu, Utsav (author), Bertotti, G. (author), Willett, Sean D. (author)We present a model for the dynamic formation of the forearc high of southern Anatolia where sedimentation in the forearc basin leads to thermally-activated deformation in the lower crust. Our thermo-mechanical models demonstrate that forearc sedimentation increases the temperature of the underlying crust by “blanketing” the heat flux and...journal article 2020
