Because of limited seismic resolution, the internal geometry of oil reservoirs hosted in deep-water lobe deposits is usually associated with a high degree of uncertainty. Therefore geological models capable of including realistic but uncertain geometries are crucial in order to minimize development risk of such reservoirs. Conventional cell-based modelling techniques struggle to reproduce the complicated spatial structures present in deep marine systems, and therefore a modelling approach based on surface rule-based modelling has been created, with the aim of reproducing complex geometries at different scales in binary sand/shale systems. Surface rule-based models have successfully reproduced deep-water lobe systems with realism, including their different stacking patterns. The new code includes a fast and simple way of generating hierarchical deep-water lobe models that include erosion. This will help us to understand the influence of different geometries on reservoir properties.
