Reservoir Characterization and Volumetric Analysis of “Lona” Field, Niger Delta, Using 3-D Seismic and Well Log Data

Abstract

An integrated 3-D seismic data, checkshot data and a suite of four well log located at the Lona field, Niger Delta were analysed with Petrel software for reservoir characterization and volumetric analysis of the field. The method adopted involves petrophysical analysis, structural analysis, volumetric analysis and reservoir classification. Detailed petrophysical analysis revealed three reservoirs. Average reservoir parameters such as porosity (0.25), gross thickness (27 m), hydrocarbon saturation (0.66) permeability (3734 md) and net-gross (0.54) were derived from the petrophysical analysis. Structural analysis of the data showed fault assisted anticlinal structures which serve as structural traps that prevent the leakage of hydrocarbon from the reservoirs.
