Hydrocarbon Reservoir Characterization and Modelling, Akos Field, Niger Delta, Nigeria

Abstract

In this research, seismic and well logs data were used for constructing a 3-D static reservoir model of Akos-Field, The aim was to generate the structural and petrophysical models of the delineated reservoirs. The reservoir modeling involves the integration of structural information and rock properties using geostatistical techniques. Two reservoirs A and B were observed in the well logs. Fault polygons were used in building the structural model. The lithological facies architecture was simulated using a sequential indicator while the porosity, net to gross, water saturation and permeability modeling were simulated with sequential Gaussian simulation. The modeling shows that reservoir B has good petrophysical data distribution than reservoir A. The STOIIP estimation shows that the approximate volume of hydrocarbon that can be obtained in reservoirs A and B are and   Stock Tank Barrels (STB) respectively. The results show that the Akos field has hydrocarbon potential for development.
