Fitting Curvilinear Stratigraphic Grids to Horizons and Faults.

in: Proceedings of the June 1999 Gocad Meeting.

Abstract

Building faulted stratigraphie grids can be a very difficult process. Indeed, Taking into account the fault geometries may lead to a lot of degenerated cells, and trying to avoid these may prove extremely difficult. Although there are already methods allowing for a quick and clean construction in sorne cases, using 2D parametrization(s) and morphing vectors ([Bombarde 97), [Mallet 9S}, [Levy 9S}), such methods are only applicable when the top and bottom horizons defining the grid are topologically equivalent. This paper introduces a new breed of methods, using a 3D parametrizer (or, eventually, a 2.5D parametrizer). Such methods have a much broader base of applications, and relies heavily, once again, on the D. S. I. method ([Mallet 92j).
