Abstract
Object-based simulation (OBS) is a powerful method to reproduce complex sedimentary heterogeneities but raises significant conditioning challenges. Reconciling OBS with various types of data is an ambitious work that we propose to address using a parameterization able to mimic depositional processes and concepts. Focusing on channelized systems, a review first attempts to highlight the characteristics of both deep-water and fluvial environments that should be accounted for, alongside of the field data that have to be honored. A new workflow for channel simulation is then proposed. It starts from channels - interpreted on seismic or stochastically simulated and migrates or retro-migrates it accordingly to defined stacking relation to reconstruct a complete environment. Well data condition the channel paths while target Net-To-Gross ratio steps in channel numbers and their geometrical parameters. For now, two technical tools have been developed to help realizing this challenging task. The first one is a re-parameterization process of NURBS surfaces that facilitates these object manipulation. The second one integrates oxbow lake data in a retro-migration procedure. These preliminary works henceforth open the way to the implementation of the complete workflow and its application to a case study.
