Abstract: This research was centered around making estimates of petrophysical measures in sandstone reservoirs in Zeta Field, Onshore Niger Delta. The petrophysical measures estimated were porosity, permeability, water and hydrocarbon saturation, volume of shale and net-to-gross variations. To this end, seven (7) well logs were analysed. The results of the analysis revealed the presence of 3 viable hydrocarbon-bearing sandstone reservoirs. Correlation of these sand bodies show that each of the sand units spreads through the field, varying in thickness and some units occurring at greater depth than their adjacent unit which is perhaps a sign of faulting.
