The study to define the degree of compartmentalization along with the associated
uncertainties has been done to aid the exploration sector to maximize its hidden potentials.
Statfjord reservoir as the object of this study provides a robust clastic data which contains six
different zones based upon petrophysical analysis. Seismic data interpretation is the core method
to generate the structural and surface interpretation, followed by the structural framework
modeling to define the juxtaposition along with the segmented fault system. The result shows
moderate clay content (Effective Shale Gouge Ratio) ranging between 40% - 60% with 0.3 MD
(millidarcy) permeability, which indicates moderately sealing faults. The compartments also
considered having two different scenarios concerning its migration pathway. This is because of
the limited well data at the reservoir system, therefore, two different Oil to Water Contact
(OWC) value has been added (-2717m and -2617m).
