Boersma, Q.D. (author), Douma, L.A.N.R. (author), Bertotti, G. (author), Barnhoorn, A. (author)In layered materials, the deformation style, orientation, confinement, and 3D connectivity of natural fractures is generally impacted by changes in sedimentary facies and alternations in mechanical properties. In this study we address this effect and perform a numerical sensitivity analysis. Mechanical properties, confining pressures, and...journal article 2020

(author)It is unclear how the crustal-scale erosional exhumation of continental domains of the Moroccan Atlantic margin and the excessive subsidence of its rifted domains affected the Late Jurassic-Early Cretaceous post-rift evolution of the margin. To constrain the km-scale exhumation, we study the structural evolution of the Jbel Amsittene. This...journal article 2020

Boersma, Q.D. (author), Athmer, Wiebke (author), Haege, Martin (author), Etchebes, Marie (author), Haukås, Jarle (author), Bertotti, G. (author)Production from the Ekofisk Chalk Field in the North Sea is believed to be significantly influenced by the presence of a connected fault and fracture network. In the current study, we create a 3D seismic discontinuity cube which is representative of this network within the southern part of the Ekofisk Field. This is done using a multiscale...journal article 2020

Charton, R.J.G. (author), Bertotti, G. (author), Duval Arnould, Aude (author), Redfern, Jonathan (author), Storms, J.E.A. (author)Continental passive margins and their hinterlands in the Atlantic realm have been the locus of many Low Temperature Thermochronology (LTT) and time-Temperature (t-T) modelling studies that evidence pre-, syn- and post-rift episodic km-scale exhumation and burial episodes. In this study, we integrate data from over 30 published LTT and t-T...journal article 2020

(author), Souza, Zorano S. (author), Nogueira, Francisco C.C. (author)Rifting and related normal stress regime in the equatorial continental margin of Brazil ceased during the Late Cretaceous, when the stress regimes in eastern South America and West Africa changed to induce strike-slip or reverse motion. In this study, we explore the postrift tectonic, geomorphic, magmatic, and sedimentary responses to stress...journal article 2020

(author)The carbonate rocks exposed in the Irecê (Brazil) are pervasively affected by hydrothermal silicification and dolomitization. These mineralizing events drastically changed the original petrophysical properties of the host rock. In order to understand the role played by deformation mechanisms and tectonic evolution of these carbonates on the...conference paper 2020

Boersma, Q. (author), Prabhakaran, R. (author), Hilario Bezerra, F. (author), Bertotti, G. (author)In carbonate rocks, channelized fluid flow through fracture conduits can result in the development of large and connected karst networks. These cavity systems have been found in multiple hydrocarbon and geothermal reservoirs, and are often associated with high-permeability zones, but also pose significant challenges in drilling and reservoir...report 2019

Quick and realistic predictions of the fracture network organization and its fluid flow efficiency from limited amount of data is critical to optimize resources productivity.

(author), Albert, Richard (author), Gerdes, Axel (author), Bertotti, G. (author)Early marine diagenetic dolomite is a rather thermodynamically-stable carbonate phase and has potential to act as an archive of marine porewater properties. However, the variety of early to late diagenetic dolomite phases that can coexist within a single sample can result in extensive complexity. Here, the archive potential of early marine...journal article 2019

Prabhakaran, R. (author), Bruna, P.B.R. (author), Bertotti, G. (author), Smeulders, D.M.J. (author)Representing fractures explicitly using a discrete fracture network (DFN) approach is often necessary to model the complex physics that govern thermo-hydro-mechanical-chemical processes (THMC) in porous media. DFNs find applications in modelling geothermal heat recovery, hydrocarbon exploitation, and groundwater flow. It is advantageous to...journal article 2019

Bruna, P.B.R. (author), Lavenu, Arthur P.C. (author), Matonti, Christophe (author), Bertotti, G. (author)It sounds counter-intuitive to consider contraction features such as stylolites as potential conduits for flow. However, this idea has grown since 1980, with geoscientists finding many examples principally in carbonate reservoirs where stylolites can be considered as fluid-efficient features. Among others, these features can be reactivated...journal article 2019

Such images might also be good analogues of subsurface naturally fractured reservoirs and can be used to make predictions of the fracture geometry and efficiency at depth. However, even when supplementing...journal article 2019

(author)Low-temperature thermochronology studies revealed major exhumation events affecting domains in the hinterland of the Central Atlantic margins, where Palaeozoic and/or Precambrian basement is exposed. Thus, domains traditionally assumed to be stable since at least the Variscan and juxtaposed to subsiding Meso-Cenozoic basins, appear to be...journal article 2019

Boersma, Q.D. (author), Hardebol, N.J. (author), Barnhoorn, A. (author), Bertotti, G.

Previous modelling studies have shown that orthogonal fractures may be caused by a local stress...journal article 2018

Charton, R.J.G. (author), Bertotti, G.

The relationship between the exhuming and subsiding domains is poorly understood. In this study, we reconstruct the evolution of a 50 km long...journal article 2018
