Lead Identification in Part of the Northern Depobelt, Niger Delta, Nigeria

The concept of sequence stratigraphy has been employed to establish a dip oriented sequence stratigraphic framework for five exploration wells in the northern depobelt, Niger delta. A review of the geology and the petroleum systems of the depobelt was also carried out. These enabled the sand bodies that are chronostratigraphically confined within the earliest genetic sequences of the paralic Agbada Formation in the area to be rated as possible hydrocarbon bearing or not. These genetic sequences occur in a synclinal low - an unusual play in the Niger delta - on the seismic section and display bright spots. Seismic reflection termination patterns suggest existence of stratigraphic traps at such depth interval. An exploratory well targeted not only at finding oil but to understand the geology of such an area is hereby recommended, more so that some fields in the depobelt are now classified and sold as marginal fields. The two oldest sequences intercepted by the well should be cored for detailed sedimentological studies.
