Abstract

Nowadays, the awareness amongst the reservoir engineers of proper practice in upscaling a static model which contains millions of gridblocks into a coarser dynamic model has increased significantly. In this report, a new upscaling workflow is developed for the PETRONAS full field review (FFR) team to assist them in constructing a reliable dynamic model to meet the objective(s) of their project. In order to come up with a helpful upscaling workflow, a few upgridding and upscaling methods are being tested to assess the performance of each method on a real field model (Field 'X'). The upgridding methods involved for assessment include the simple uniform layering method, the variance in saturation method and the Stern and Dawson method. Whereas, the upscaling methods involved include the rock curve method, Vertical Equilibrium (VE) method, Kyte and Berry (KB) method, Stone method, Hewett and Archer (HA) method and Transmissibility-weighted (TW) method. From the findings on the upgridding activities, it can be summarised that the variance in saturation method is the most suitable method to be used for Field X, where the layering can be further coarsened probably up to 20-layers scheme with that method. It is also observed that the Stern and Dawson method does not perform as good as the variance in saturation method and the uniform layers method happens to work surprisingly well for the Field X model. From these upscaling activities, it can be summarised that the VE method does not work for Field X, the KB method performed worse than the Stone method and the TW and HA methods have the same results with the rock curve method. In conclusion, the objective of developing a new upscaling workflow for the PETRONAS FFR team or other simulation project is met mainly referring to the literature reviews and supported by some of the findings of this paper.
