The eastern part of the dataset is in the transitional detachment fold zone and contains subtle faulting along with low wavelength folding of Eocene to Quaternary stratigraphy. The west of the survey, situated in the outer fold and thrust belt, is dominated by closely spaced thrust faults.<\/p>\n The Niger Delta Basin was formed during the Late Cretaceous and contains up to 12 km of Late Cretaceous to Quaternary-aged clastics, deposited in an upward-coarsening regressive deltaic sequence. The main source rocks are Akata Formation marine shales and Lower Agbada Formation paralic shales.<\/p>\n Proven reservoirs in the basin are found in unconsolidated sandstones of the Agbada Formation deposited as stacked turbidite channel and fan complexes (Tuttle et al., 1999). The largest accumulations are trapped in roll-over anticlines in the hanging walls of growth faults, but hydrocarbons may also be found in fault closures and subtle stratigraphic traps.<\/p>\n \u201cReprocessing has enhanced imaging of targets with improved illumination of complex structures associated with the diapiric movement of the Akata Shale Formation,\u201d says Avril Burrell.<\/p>\n
