Object Modelling and Related Uncertainties in a Fluvio-Lacustrine Environment with Geological and Seismic Drivers

Summary This paper is presenting an application of object-based modeling technique for a specific fluvio-lacustrine environment. The geological context is firstly depicted. Subsequently, the available information is described and the motivation for using object-based modeling is explained. The challenging part of the study was to build a relevant trend for object proportions; this key point is detailed. The algorithm used is then briefly recalled and some results of the facies model are presented. The last part of the paper is briefly addressing the uncertainties on the geological model to obtain hydrocarbon in place distribution. Some key messages are given as conclusion.
