Using SBED[TM] from Geomodeling, Statoil geologists, petrophysicists and reservoir engineers have been able to capture the fluid flow impact from complex, fine-scale inter-layering within heterogeneous reservoir units, improving their reservoir property simulations and reserve predictions.
For quite some time, we have been searching for a reliable downhole monitoring system for our unique and heterogeneous reservoir type (fractured granite basement), which has extremely high downhole temperatures up to 312 degrees Fahrenheit.
In layered and heterogeneous reservoirs water movement front is not always uniform due to different permeability in layers, leading to breakthrough of water in high permeable layers while in some layers oil not being displaced efficiently.
