A Review on the Concept and Utilization of Sequence Stratigraphy in the Niger Delta

Abstract

Sequence Stratigraphy incorporates comparative sea-level and time variation to analyze facie migration, and is conducted using well-logs, outcrops, cores and evaluations could be based on different set of data. Sequence Stratigraphy can be utilized to evaluate relationships between sedimentary formation within a periodic-stratigraphic system of repetitive, genetically linked layer bounded by surfaces of non-deposition or erosion, or their correlated conformities. In this study, a comprehensive review on the concept and utilization of sequence stratigraphy in the Niger-Delta was conducted. From the conceptual review study, accommodation space, depositional sequence analysis, surface, seismic and biostratigraphy were identified as key contributors to sequence stratigraphy evaluation. From the application review study, well-logs, seismic data, core-data and biostratigraphic data are very critical for effective sequence stratigraphic analysis, and are used for depositional arrangement, detection source rocks, oil & gas reservoir and seal-off section within sedimentary basins. Furthermore, Miocene sediment were observed to be predominant in the Niger-Delta formations.
