Abstract
The reliable modeling of three-dimensional complex geological structures can have a major impact on forecasting and managing natural resources and on predicting seismic and geomechanical hazards. However, the qualification of a model as structurally complex is often qualitative and subjective making the comparison of the capabilities and performances of various geomodeling methods or software difficult. In this paper, we consider the notion of structural complexity from a geometrical point of view and argue that it can be characterized using general metrics computed on three-dimensional sealed structural models. We propose global and local measures of the connectivity and of the geometry of the model components and show how they permit to classify nine 3D synthetic structural models. Depending on the complexity elements favored, the classification varies. The models we introduce could be used as benchmark models for geomodeling algorithms.

However, the qualification of a model as structurally complex is often qualitative and subjective making the comparison of the capabilities and performances of various geomodeling methods or software difficult. In this paper, we consider the notion of structural complexity from a geometrical point of view and argue that it can be characterized using general metrics computed on three-dimensional sealed structural models. We propose global and local measures of the connectivity and of the geometry of the model components and show how they permit to classify nine 3D synthetic structural models. Depending on the complexity elements favored, the classification varies. The models we introduce could be used as benchmark models for geomodeling algorithms.</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Metz</li><li>Nancy</li></settlement><orgName><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Pellerin, Jeanne" sort="Pellerin, Jeanne" uniqKey="Pellerin J" first="Jeanne" last="Pellerin">Jeanne Pellerin</name></region><name sortKey="Botella, Arnaud" sort="Botella, Arnaud" uniqKey="Botella A" first="Arnaud" last="Botella">Arnaud Botella</name><name sortKey="Caumon, Guillaume" sort="Caumon, Guillaume" uniqKey="Caumon G" first="Guillaume" last="Caumon">Guillaume Caumon</name><name sortKey="Julio, Charline" sort="Julio, Charline" uniqKey="Julio C" first="Charline" last="Julio">Charline Julio</name><name sortKey="Mejia Herrera, Pablo" sort="Mejia Herrera, Pablo" uniqKey="Mejia Herrera P" first="Pablo" last="Mejia-Herrera">Pablo Mejia-Herrera</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
