Abstract
Hydrocarbon reservoir beds have been delineated using direct hydrocarbon indicator on seismic sections as well as well logs data in X field, Onshore Niger Delta. The research methodology involved horizon interpretation to produce sub-surface structure map. Geophysical well log signatures were employed in identifying hydrocarbon bearing sand. The well-to-seismic tie revealed that the reservoir tied directly with hydrocarbon indicator (bright spot) on the seismic sections. The major structure responsible for the hydrocarbon entrapment is anticline. The crest of the anticline from the depth structural map occurs at 3450 metres.

The data used for this study are composite geophysical well logs, seismic sections, check shot data and base map of the seismic lines which were obtained from Nigeria Agip Oil Company Limited
Summary
The Niger Delta is a proven prolific hydrocarbon system with a number of world-class oil discoveries. The objective of hydrocarbon exploration is to identify and delineate structural and stratigraphic traps suitable for economically exploitable accumulations and delineate the extent of discoveries in field appraisals and development. These traps could be very subtle and complex and are difficult to be mapped accurately [1]. Seismic and well log data are widely used in petroleum exploration to map the subsurface. The two data sources are complementary: seismic profiles provide an almost continuous lateral view of subsurface, whereas well logs yield fine vertical resolution of the geology at the borehole. With relatively high precision, the structural and stratigraphic changes from the arrival times and amplitudes of the reflection events
