Abstract Integrated field development studies were performed to increase oil recovery from the Marrat reservoir in the Umm Gudair field, a large, low permeability, complex, naturally fractured and highly faulted carbonate reservoir. The studies involved rebuilding the static model...

... (Vshale) and porosity. The initial permeability values were also taken from the petrophysical permeability calculation. Since the Slochteren formation has some dip in this area, it was necessary to include the formation dip in this otherwise simple (layer-cake) model, to be able to match the structure...

Hydraulic flow unit (HFU) determination is adopted instead of the lithofacies model, not only to introduce more complexity for representing the variances among flow units, but also to establish a higher correlation between porosity and permeability. By means of artificial intelligence (AI...
