Abstract

Foraminiferal biostratigraphy and paleoenvironmental analysis of the sediments penetrated by OSM well in the Coastal Swamp Delta Depobelt, Niger Delta Basin was carried out in order to determine foraminiferal biozonation, relative age, paleobathymetry and depositional environment of the area of interest. A total of twenty-eight (28) foraminifera species were recovered; three (03) foraminifera species were planktonic, while eight (8) and seventeen (17) foraminifera species were calcareous and agglutinated benthic foraminifera respectively. Four planktonic foraminifera biozones of Blow (1979) were identified: namely (N17-N16, N16-N15, N15-N14 and N13- N12). The result of the analysis indicates that the entire analyzed interval (6140ft – 12800ft) was deposited during the Middle Miocene to Late Miocene within a coastal deltaic to an inner neritic depositional setting.
