Evaluation of Fault Compartmentalization of "XAS" Reservoir, Onshore Niger Delta

The potential that the faults in the XAS reservoir might possibly result in compartmentalization was evaluated. The hypothesis is that unexpected compartmentalization issues due to false negatives and false positives, can infringe on earlier supply arrangement and can thwart production schemes and reserves that are booked from the field, booking of reserves is tight and highly regulated by government authorities. Data were obtained that consists well logs, 3D seismic volume for the XAS field. Petrel version 2014 was used for modelling, the structural model unravel that the reservoir has three faulted compartments. The petrophysical properties of the fault zone which comprised the fault zone permeability, the shale gouge ratio, the fault thickness were observed to fall short of the conditions for constraint of fluid flow across faults in the reservoirs. Thus, the faults are non-sealing but suggested to be barriers or/ baffles.
