Abstract
Pore pressure predictions for an onshore Niger Delta area were made using offset well logs. Mild – to – moderate overpressure regime was estimated in the area. Onset of mild overpressure (<0.6 psi/ft) in the area is at about 6600 – 11500ftss. The pressure increases with depth to become moderately overpressured (< 0.8 psi/ft) throughout the depth extent of about 12200 – 15700ftss.
