Well log data acquired from three wells (BOK – 14, BOK – 16 and BOK – 19) from an onshore Niger Delta field (BOK) where used to carry out petrophysical analysis of the field to determine the prospectivity of the field. The Petrel software 2014TM was used for the petrophysical analysis and prospect identification. The petrophysical analysis revealed four hydrocarbon bearing reservoir sand formations with volume of shale ranging from 13.09% to 22.95%, effective porosity ranging from 19.24% to 24.23, 13% to 22.85%, net to gross ranging 38.66% to 75.40% and hydrocarbon saturation of 54.85% to 72.53%. From the petrophysical properties computed after the detailed petrophysical analysis from the well log data, it was evident that the identified reservoirs in BOK field had very good to excellent petrophysical properties ranges and were therefore prolific, holding great prospects for hydrocarbon fluid saturation which could be exploited for profitable use.
