    Pore Pressure Prediction (PPP) has been proven to be more difficult in basins like the Niger Delta where the subsurface pressure system is complex. Failure of PPP practioners to recognize lateral and vertical variations of formation pressure even within the immediate vicinity of local geology had led to greater uncertainty and safety threat in drilling activities. Hence; this work attempted to investigate subsurface pressure pattern in Ada field, on Onshore Niger Delta depositional belt. Wireling logs, mud weights and reservoir pressures from four wells were analysed for this purpose. The overpressure in field is seen to be mild, i.e. below 0.5 psi/ft but it exceeded 0.6 psi/ft at depth ~12000 ft TVDml with overpressure magnitude of 1682 psi. The study revealed the effect of hydrocarbon production in the field as indicated by drained reservoir pressures. The field is seen to have high.. Read More»
