Abstract:
An integrated 3D seismic data, checkshot data and a suite of well logs for four wells located at the Lona field, Niger Delta were analysed with Petrel software for reservoir characterization and volu-metric analysis. The method employed involves petrophysical analysis, structural analysis, volume-tric analysis and reservoir ranking. Detailed well log petrophysical analysis revealed three potential reservoirs. Average Reservoir parameters such as porosity (0.25), gross thickness (27 m), hydro-carbon saturation (0.66), permeability (3734) and net-gross (0.54) were derived from petrophy-sical analysis. Structural analysis showed fault assisted anticlinal structures which serve as struc-tural traps that prevent the leakage of hydrocarbon from the reservoirs. Volumetric study of the hydrocarbon in place showed that the reservoirs are of appreciable areas and thicknesses. The volu-me of hydrocarbon originally in place was estimated to be 550 thousand barrel of oil. The three reservoirs were ranked using average results of petrophysical parameters. R1 was found to be more prolific while R2 was found to be least prolific within Lona field.
