Sequence Stratigraphic Framework of the “Paradise-Field”

The “Paradise-Field ” is located within the Coastal Swamp II and the shallow western offshore of the Niger Delta. The high resolution biostratigraphic report for the representative well P-1 in the “Paradise Field ” was used in the sequence stratigraphic analysis. The eustatic cycles recorded in the penetrated stratigraphic intervals have been correlated to the regional chronostratigraphy of the Niger Delta for the prediction and dating of sequences recognized from the well logs. In the study area, one candidate maximum flooding surface (MFS) dated 11.5Ma was recognized based on the maximum shale peak, the separation of high neutron and low density values with corresponding high gamma readings. Also, one sequence boundary (SB) dated 10.6Ma is identified based on the inflection from overall progradation to overall retrogradation of parasequences in the shallowing sand units. The relative thickness of the systems tracts reveals changes in sediment accumulation rates as a result of varying local conditions which may include the effect of gravity, tectonics, availability of accommodation space, and eustatic sea level changes. In the five wells studied, the three systems tracts (the highstand systems tract, the low stand systems tract, and the transgressive systems tract) are all represented except in Well P-1 with only LST and TST.
