Fault Modeling and Seismic Attributes Of Nana Field, Niger Delta Nigeria

Abstract

This study examined the application of 3-D seismic and well log data for proper optimization and development of hydrocarbon potential in “ NANA ” field of Niger-Delta Province. The data were conditioned for interpretation using Petrel software. These delineated reservoirs found in each well were then correlated across the field. A well-to-seismic tie was done using Seismic attributes (Frequency, RMS amplitude, Acoustic Impedance and Variance) and property modeling (Facies, net-to-gross, porosity, water saturation, hydrocarbon saturation and permeability) were distributed stochastically within the constructed 3-D grid. The reservoir structural model shows a system of differently oriented growth faults are quite extensive). The trapping mechanism is a fault assisted anticlinal closure.. This study demonstrated the effectiveness of 3-D static modeling technique as a tool for better understanding of spatial distribution of discrete and continuous reservoir properties, hence, has provided a framework for future prediction of reservoir performance and production behavior of the reservoir..
