Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta

About this book

Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta is available just as exploration and production activities are moving into the little known deep water terrain of the Niger Delta. A thorough understanding of the Cenozoic Niger Delta will improve understanding and exploration of the evolution of deeper offshore belts, help researchers strengthen and refine existing Neogene nannofossil biostratigraphic schemes for the Niger Delta region, and gain a better understanding of the relationship between nannofossil assemblage variations and paleoenvironments.

The hydrocarbon reserves of the Niger Delta are an extremely valuable natural resource. Biostratigraphy and Correlation play important roles in the discovery, development and maturing of hydrocarbon fields. Calcareous nannofossils have been important tools for the stratigraphers in the Niger Delta and in recent years exploration has moved into deeper offshore areas where nannofossils are more abundant and diverse. Little has been published about the calcareous nannofossil chronostratigraphy of the Niger delta. Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta fills the gap for earth scientists and those working in the oil and gas industry.
