Reservoir Characterization and Petrophysical Analysis of “Brown Field” in the Southern Niger Delta, Nigeria

Veronica E. Ibanga, Thomas A. Harry, Ekpedeme R. Asuaiko & Tejumade A. Owoeye · Asian Journal of Geological Research · 2026

Accurate reservoir characterisation is essential for understanding the distribution, quality, and structural controls of hydrocarbon-bearing formations. In the Niger Delta, integration of petrophysical well-log analysis with 3-D seismic interpretation provides a basis for evaluat...

Foraminifera, Biostratigraphic and Paleoenvironmental Analysis of “X-1” Well, on the Western Sector of the Niger Delta Basin, Nigeria

Anietie R. Etim, Thomas A. Harry, Anietie E. Ekot & Abraham C. Udoh · Asian Journal of Geological Research · 2026

A foraminiferal biostratigraphic and paleoenvironmental study was conducted on ditch-cutting samples from well X-1 (1870–1320 m), located in the western sector of the Niger Delta Basin, southern Nigeria. The objectives were to determine the stratigraphic age, depositional paleoen...

Biomarker Distribution and Implications for Organic Matter Input and Depositional Environment of Shales from the Utapate Oilfield, Southeastern Niger Delta Basin, Nigeria

Ekpedeme R. Asuaiko, Thomas A. Harry, Anietie E. Ekot, Paul A. Udofia & Itohowo O. Akpan · Asian Journal of Geological Research · 2026

Biomarker geochemistry provides a powerful means of reconstructing organic matter provenance, depositional environment, and thermal maturity of sedimentary source rocks. This study investigates the distribution of saturated and aromatic biomarkers in two shale samples from the Ut...
