Abstract
The ENF field is located within latitudes 4°50’42.36N to 4°56’43.35N and longitude 6°15’54.99E to 6°27’24.71E in Niger Delta. Reservoir characterization involved the quantitative distribution of petrophysical parameters (porosity, permeability, net-to-gross, water saturation) derived from log interpretation within a particular reservoir sand interval, while prospectivity studies involve the evaluation of ENF field for more prospects and leads. Well logs (density, neutron, GR, resistivity and sonic) were utilized for this study. Well correlation was done across seven wells, and three reservoir sands of interest (sand A, C and I) were picked using GR and resistivity. The reservoir sand thickness for A, C, and I were 404.32, 306.65 and 193.86, respectively, with a very good porosity and permeability of (0.25, 0.27, 0.19) and (1098.21mD, 1585.81mD, 850.17mD) Seismic data were thoroughly interpreted and a time surface map was generated. The velocity model was carried out, which helped in time depth conversion (converting time surface map to depth surface). The fault within the ENF field was modelled utilizing the top and base depth surface map, and the major fault served as a boundary to pillar grid the reservoir sands. The volume of hydrocarbon was calculated for each reservoir, and the result showed that reservoir A has 411MMSTB (Million Stock Tank Barrels), reservoir C 654MMSTB while reservoir I has 1351MMSTB. the field was evaluated for more prospect and leads utilizing seismic attributes (RMS and maximum amplitude). The bright spot amplitude anomalies showed that there is hydrocarbon. Therefore, more wells should be drilled within the prospect for optimal recovery of hydrocarbon.
