ABSTRACT
This work was done by studying foraminifera, a single-celled protist, with shells on twenty five (25) ditch cutting samples from interval 65200 – 7700ft of DA-1 well. The samples were subjected to standard micro paleontological sample processing techniques, which involves preparation sample and slide preparation. The lithology is composed of gray shale with intercalation of sand/sandstone beds. A chat which displays the distribution, abundance, diversity, lithostratigraphy, paleo depositional environment, biozonation and age dating of the well are presented. The zoning was established in correspondence to the works of Blow et al (1969, 1979). Finally, it was inferred that the interval penetrated by the well corresponds to the Agbada Formation, and they are of the middle Miocene age. The alternation of sands and shales within the sequence provides the combination of source and reservoir essential for hydro carbon generation and accumulation.
