Abstract: In the “HONYX” Field, Niger Delta, Gulf of Guinea, seismic attributes were employed to analyze the structural trend and identify regions that are favorable for hydrocarbon accumulation. Nestled in the Niger Delta basin, the ‘HONYX’ field spans approximately 75,000 km2 and is situated between latitudes 4°N and 6°N and longitudes 3oE and 9°E. One of the petroleum companies in Nigeria provided the data set, which included the Base map of the study region, well logs (LAS format), 3-D seismic data (SEG-Y), and Check shot survey used for this work. Faults picking, horizon mapping, and structural map production were the techniques employed to accomplish this goal. The DHIs (Sweetness and Instantaneous frequency), RMS Amplitude, and Variance were the seismic properties that were employed. In the research area, the Sweetness exhibits a strong amplitude in regions where there are isolated sand bodies surrounded by shale. On the Sweetness time slices, they appeared as brownish patches. From the seismic data, the instantaneous frequency parameter was also produced. On the sweetness time slice, however, the zone or zones with strong amplitude match the instantaneous frequency, which displays low frequency anomalies suggestive of cracked and hydrocarbon zones. The Variance Trends Analysis showed the two main faults in an east-west orientation. Following that, structural maps of depth and time were created for three defined horizons. Finally, this study demonstrated that the application of seismic attribute analysis has uncovered several hydrocarbon prospective zones that could be further revalidated and evaluated to a hydrocarbon prospect, away from the producing zone (which is common to all three reservoir tops). These prospect areas were identified on the three depth maps. The “HONYX” Field is effective for accumulating hydrocarbons, according to the observed data.
