The proposed project addresses a fundamental question in reservoir modelling – how can we upscale detailed fault data into grids of the reservoir model and flow simulators without losing crucial information?

In the case of sedimentary heterogeneity in the reservoir, this subject has been extensively studied. Contrary, the impact of upscaling of faults on the reservoir simulator performance has received little attention.

We will approach this challenge in a work flow that spans three subjects:

1. Processing of CIPR’s database on faults in reservoirs, emphasising damage zone geometry
   
   
2. Building detailed fault damage zones in a modelling tool (software) with basis in the statistical data
   
   
3. Bring the geo-model into a reservoir simulator and then perform stepwise upscaling (cm-dm-m-10m) of the model in parallel with a sensitivity study for the impact on flow.

The planned activity follows the work flow of the Fault Facies project. This strategic project aims on representing fault impact on reservoirs in a volumetric way, by treating faults as physical bodies.

We believe this approach to represent the future in assessing the impact of fault zones on reservoirs.
