Goscope project : Extracting information from the seismic

in: 21st gOcad Meeting, ASGA

Abstract

The goal in this new project is to extract geological and geometrical information directly from the seismic and well data. For example : • Extracting a triangulated horizon directly by picking one or several points on this horizon in the seismic cube. • Computing the field of normal vectors to the layers inside a seismic cube. • Identifying the facies from seismic and well data. • Extracting faults, channels, etc..... In this paper, we present the first results of the automated extraction of horizons from a seismic cube. We first compute the set of grid nodes belonging to the horizon. This set is defined as the neighboring nodes of one or several representative seeds and having the same characteristics as these seeds. The similarity between a node and a set of seeds is defined by computing their multiple correlation coefficient on the properties attached to the surrounding nodes. After that we build the corresponding triangulated horizon from this set of points stored in a 2D grid.
