Sedimentary units generally present anisotropy in their hydraulic properties, with higher hydraulic conductivity along bedding planes, rather than perpendicular to them. This common property leads to a modeling challenge if the sedimentary structure is folded. In this paper, we show that the gradient of the geological potential used by implicit geological modeling techniques can be used to...

A workflow to facilitate three-dimensional geometrical modelling of complex poly-deformed geological units

Maxelon, Michael ; Renard, Philippe ; Courrioux, Gabriel ; Brändli, Martin ; Mancktelow, Neil

The three-dimensional (3D) geometry of complexly deformed regions is often beyond the scope of simple 2D and 2.5D representation in cross-sections and block diagrams. Methods must be developed for fully three-dimensional representation. A workflow for such three-dimensional modelling of structurally complex areas is presented. Data requirements are tailored to typical results of structural field...

Three-dimensional geometric modeling of a faulted domain: The Soultz Horst example (Alsace, France)

Renard, Philippe ; Courrioux, Gabriel

In: Computers & Geosciences, 1994, vol. 20, no. 9, p. 1379-1390

This paper describes an example of 3-D modeling using GOCAD software, a geometric modeler designed for geological surfaces. The problem is to build a geometrically consistent model of a fault and layers system starting from faults' traces on cross sections, cross sections derived from seismic profiles, and drillhole data. A methodology is proposed and discussed. The main problems in modeling...
