A Software Agent Based Tool for Generating and Validating Structural Interpretations

The paper examines the problem of validating the geological interpretation related to a 3D structural model in view of new information coming from a drilling in progress. Considering a given geological interpretation expressed as a Geological Evolution Schema [Brandel & al. 2005], there exists definite rules that allow to determine whether the markers corresponding to two geological surfaces can be neighbours or not along a drilling trajectory. The validation problem then consists in checking the compatibilities of the various couples of markers successively met by the drilling trajectory. This is by nature a distributed problem. We propose to model it by means of a Multi-Agent System [Bradshaw 1997, Briot and Demazeau 2001] and to solve it thanks to an Eco-Problem Solving methodology [Ferber 1999]. Preliminary results are given, which demonstrate that the proposed method is sound and promising.
