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...
