BIOSTRATIGRAPHY OF WELL B NIGER DELTA NIGERIA

This research provides an in-depth sedimentological and palynological analysis of the Well B strata in the Agbada Formation of the Niger Delta Basin, a region of significant hydrocarbon potential. The study aimed to characterize the lithological and depositional attributes of the formation by examining core samples of sandstone, shale, and siltstone. Sedimentological analysis involved granulometric techniques, where sieve analysis was performed to determine key parameters such as grain size distribution, sorting, skewness, and kurtosis. The results revealed that the sandstones in the study area are predominantly poorly sorted, finely skewed, and mesokurtic, indicative of a high-energy fluvial depositional environment with abrupt sedimentation processes. In parallel, the palynological investigation identified diverse dinoflagellate cysts and other microfossils, including Glaphyrocysta exuberans, Membranophoridium perforatum, and Systematophora placacantha. These findings suggest that the depositional environment was influenced by varying energy regimes and possible fluctuations in salinity and other paleoenvironmental factors. The integration of sedimentological and palynological data supports the interpretation of a dynamic depositional setting dominated by fluvial and transitional marine processes. The study's outcomes are crucial for understanding the sedimentary dynamics and stratigraphic evolution of the Agbada Formation, providing valuable insights for hydrocarbon exploration and reservoir characterization. The research also emphasizes the importance of continued investigation into facies distribution and depositional environments to refine stratigraphic models and enhance predictions of resource potential within the Niger Delta Basin.
