This study presents the log analysis results of a suite of geophysical logs comprising gamma ray (GR), resistivity (LLD), neutron (PHIN) and density (PHID) logs from six wells in ‘Laja’ Field located in the Niger delta. The analysis was carried out to evaluate the field’s hydrocarbon prospect i.e. identify hydrocarbon bearing reservoir(s) and study reservoir properties based on log data from the six wells. Eleven zones of interest (sand bodies) were delineated and correlated across this field. Six of these sands were further identified as potential hydrocarbon reservoirs. The computed petrophysical parameters for the reservoir layers have porosity, f range of 13% – 38% and hydrocarbon saturation, Sh range of 0.16% to 22.2%. The analysis indicates that reservoirs (sands) are encountered at depth range of 4350m to 7650m with relative permeability to oil ranging from 314.0 to 18521.8md. These results on the whole suggest that the reservoir sand units of ‘Laja’ Field contain significant accumulations of hydrocarbon
