Abstract — 3D geometric modeling of fractured geological systems – an improved technique
— Determining flows and transfer processes in natural fractured geologic systems receives
increasing attention for different applications in geoscience from conventional oil and gas industry,
and unconventional shale gas production, to geothermal recovery and CO2 capture and sequestration
issues. To simulate these processes am adequate geometric representation of the discretized system is
the basic requirements for finite element or finite volume simualtions. In this paper, a technical
description of an improved method to represent non-planar 2D structures of generic inclines
(representing faults and fractures) within a 3D boundary conforming Delaunay unstructured mesh
(representing the porous media) is presented.
