Hydrocarbon detection and depositional environment prognosis in the Niger Delta - Integrated insights from log and seismic avo-inversion attributes

This study demonstrates the effectiveness of integrated seismic analysis and petrophysically constrained AVOinversion for reservoir  evaluation and assessment of hydrocarbon potential and depositional environment in the Niger Delta. It is aimed at improved prediction  of reservoir fluid, lithology, and ultimately the hydrocarbon prospects, with reduced uncertainties. The results delineate the  characteristics of the reservoir sands, highlight major facies heterogeneities, unravel prolific stratigraphic features (such as channels, fan  lobes), depositional fairways and provide insight into the mapped geology. These are expected to consequently reduce the uncertainties  associated with the prospects for economic decision making.
