Innovative Application of RGT-driven Sequence Stratigraphic Analysis from Siliciclastic Analogue Model to Real Seismic Datasets

Seismic stratigraphy can be a complex discipline for geoscientists who have no access to outcrop analogues or actual depositional system models to apply uniformitarianism. This paper shows how digitized analogue models from sand-boxes can be used to test different definitions and resolutions of seismic images to build stratigraphic models and give new insights for real basin seismic data interpretation using the Relative Geological Time ‘RGT’ method ( Pauget et al, 2009 ). The presented workflow is here applied to synthetic 3D seismic datasets (courtesy of SeisMomentum Limited) generated from the ‘XES02’ analogue model (‘experimental Earthscape Basin’ facility, National Center for Earth-Surface Dynamics at the University of Minnesota). The key phases of the analogue basin infill kinematics are emphasized and lately compared to real seismic datasets featuring depositional sequences with various cycle orders, dimensions, sedimentation rates and depositional environments.
