“…This criterion significantly exceeds the vertical 329 resolution of field mapping using differential GPS (Maerten et al, 2001;Resor, 330 2008). Alternatively, fold width could be defined as the point where a certain 331 minimum dip is reached (1-2 degrees for typical field compass measurements).…”

“…The structural model is built through successive backward geological deformations which is called restoration. Various surface restoration methods exist [18] and also some volumetric solutions [12,13]. Surface algorithms unfold the layers from the present day structure back to the geometry at deposition time in a single step.…”

“…In these cases, studies have demonstrated that a surface or volume restoration method must be applied to obtain a more accurate analysis of the structural deformation. For volume restoration, new approaches have been published using a mechanical or a geometric approach [10][11][12][13]. Both approaches give a kinematic restoration and a time-dependent 3D geometry which can be input to the forward simulator.…”

Re´sume´-Me´thodologie applique´e aux circulations des fluides dans les bassins faille´s -Une e´tude classique en mode´lisation en bassin en 3D se de´compose en 3 e´tapes : la mode´lisation structurale et en facie`s du bassin a`l'aˆge actuel, la reconstruction structurale par restauration et enfin le couplage de ce mode`le avec le calculateur direct pour une simulation en pression et tempe´rature. Dans cette approche, la de´formation tectonique est repre´sente´e par du cisaillement vertical le long des failles. Les proprie´te´s de faille sont des proprie´te´s de perme´abilite´intrinse`que homoge`ne dans la zone de faille, elles traduisent le caracte`re drain ou barrie`re de la zone de faille. Dans le cas ou`le bassin a subi des de´formations tectoniques importantes, ces simplifications ne traduisent pas assez pre´cise´ment la de´formation tectonique. Ceci a un impact sur l'e´valuation des pressions et la localisation des ressources en hydrocarbures. Depuis quelques anne´es, un nouveau calculateur direct pour la simulation en pression, tempe´rature est de´veloppe´a`l'IFP Energies nouvelles. En paralle`le, des outils logiciels ont e´teḿ is a`disposition sur le marche´pour offrir des sce´narios de restauration 3D. Dans cette publication, nous pre´sentons les premie`res e´tudes couplant ces diffe´rents outils sur des exemples synthe´tiques de complexite´croissante. Les exemples sont des cas inspire´s de situation re´elle et de de´formation tectonique mode´re´e. Les deux cas d'application illustrent les re´sultats de´ja`obtenus et identifient les difficulte´s du couplage.Abstract -Advanced Workflows for Fluid Transfer in Faulted Basins -The traditional 3D basin modeling workflow is made of the following steps: construction of present day basin architecture, reconstruction of the structural evolution through time, together with fluid flow simulation and heat transfers. In this case, the forward simulation is limited to basin architecture, mainly controlled by erosion, sedimentation and vertical compaction. The tectonic deformation is limited to vertical slip along faults. Fault properties are modeled as vertical shear zones along which rock permeability is adjusted to enhance fluid flow or prevent flow to escape. For basins having experienced a more complex tectonic history, this approach is over-simplified. It fails in understanding and representing fluid flow paths due to structural evolution of the basin. This impacts overpressure build-up, and petroleum resources location. Over the past years, a new 3D basin forward code has been developed in IFP Energies nouvelles that is based on a cell centered finite volume discretization which preserves mass on an unstructured grid and describes the various changes in geometry and topology of a basin through time. At the same time, 3D restoration tools based on geomechanical principles of strain minimization were made available that offer a structural scenario at a discrete number of deformation stages of the basin.

“…airplanes (Reed 1940;Ray 1984), helicopters (Odling 1997), or satellites (Holland et al 2009;Bertrand et al 2015). This technique allows researchers to capture geological features at different length scales, especially those large-scale structures (Maerten et al 2001;Watkins et al 2015). It can also help identify anomalous areas that need further detailed field mapping, and eliminate or reduce the survey tasks in certain regions (Ray 1984).…”

Abstract-Natural fractures are ubiquitous in the Earth's crust and often deeply buried in the subsurface. Due to the difficulty in accessing to their three-dimensional structures, the study of fracture network geometry is usually achieved by sampling two-dimensional (2D) exposures at the Earth's surface through outcrop mapping or aerial photograph techniques. However, the measurement results can be considerably affected by the coverage of forests and other plant species over the exposed fracture patterns. We quantitatively study such effects using numerical simulation. We consider the scenario of nominally isotropic natural fracture systems and represent them using 2D discrete fracture network models governed by fractal and length scaling parameters. The groundcover is modelled as random patches superimposing onto the 2D fracture patterns. The effects of localisation and total coverage of landscape patches are further investigated. The fractal dimension and length exponent of the covered fracture networks are measured and compared with those of the original non-covered patterns. The results show that the measured length exponent increases with the reduced localisation and increased coverage of landscape patches, which is more evident for networks dominated by very large fractures (i.e. small underlying length exponent). However, the landscape coverage seems to have a minor impact on the fractal dimension measurement. The research findings of this paper have important implications for field survey and statistical analysis of geological systems.
