Abstract

Summary

The present study is aimed to evaluate, with the aid of the CFD (Computational Fluid Dynamic) software MassFLOW-3DTM, the Thitonian sand distribution, thickness and geometry in one area on the Norwegian Sea where core data were not available.

A fan-delta system was on the highs, providing sediment transport northward into the basin. The triggering mechanism for the turbidity currents was the simultaneous Late Jurassic erosion, the Tithonian uplift and lowering of sea level.

With the aid of the numerical simulations it was possible to simulate a number of consequent flows running on a reconstructed palaeo-bathymetry.

Each flow could transport and deposit new sediments, eroding into the previously deposited layers. For each flow it was possible to evaluate grain distribution and fraction, create Net to Gross maps and recreate the stratigraphy across the basin.

The study has confirmed the capability of the software MassFLOW-3D™ to deal with multiple grain sized turbidity currents and that processed based modelling is a useful tool for predicting the distribution of sand thickness and grain size. We suggest that such an approach could form a part of a probabilistic workflow and be used to capture likely ranges of parameters for improved exploration and reservoir management.
