The aim of this research is to estimate pore pressure from well log data of the Unag Field situated Offshore in the Niger Delta Nigeria. The overpressured layers were categorised into three overpressure zones (A, B and C) using velocity and effective stress methods, respectively. The identified overpressure zones vary in thickness across the wells. Results reveal that overpressures were generated by disequilibrium compaction and pore pressures. The results further show that undercompaction (loading) mechanism of overpressure, which is characterised by gradual, and increasing slight overpressure with depth, may be the main cause of overpressure especially in zones A and B across the three wells. The research compares the Eaton’s and Bower’s pore pressure prediction methods. The Bower’s method predicted pore pressure values better than the Eaton’s method, which is in close agreement with the actual RFT data for three different zones in the studied wells. Hence, the Bower’s method is proposed as useful and a better method for predicting pore pressures in other fields in the Niger Delta Basin using well logs.
