    Structural seismic interpretation is a key component of seismic interpretation workflow, as much information on reservoir architecture which is required for hydrocarbon play assessment can be obtained. This study presents the results of the integration of structural time-depth maps to define reservoir units across five (5) well for hydrocarbon play assessment of Olaj-field within the Niger Delta basin. Two reservoir windows (R1 and R2) were delineated from five wells (W-02, 04, 06, 07 and 012). The top and base of each reservoir window were delineated from the five wells using their gamma ray and resistivity log response. Well to seismic correlation was carried out with checkshot data from well-012. Structural interpretation for inline 6975 revealed about eight (8) faults labelled (F1, F2, F16, F8, F10, F18, F17 and F6) were mapped. It was observed that about five (5) faults (F1, F10, F18, F17 and F6) were identified as synthetic faults and dip basinwards towards the southern while about three (3) antithetic faults (F2, F16 and F8) were observed which dips landwards in the western direction. These are characteristics of growth faulting within the Niger Delta basin. Structural interpretation revealed a highly faulted reservoir system which depicts the tectonic setting of the Niger Delta.
