Abstract
The purpose of this study was to evaluate the Anyi field's seismic volume in order to provide the best structural frameworks for the D5000 reservoirs, which would be utilized to create precise static models. Using fault representations and depth-converted surface maps, the reservoir's structural model was built. There are two main East-West oriented faults that define the reservoir's structural structure. The Amosi growth fault borders it to the north, while the Klin boundary fault borders it to the south. It is structurally an elongated rollover anticline that is oriented east-west. Channels and shorefaces make up the majority of the reservoir. The data was revalidated and quality-checked, and a thorough literature study was carried out. A MADCOW bandpass filter was used to reduce both coherent and random noise in the seismic data. Well-toseismic calibration was then performed utilizing Anyi-001's sonic log. They interpreted the fault and horizon. Checkshots from Anyi-006, from which the time and depth map was constructed, were used to simulate velocity. Amplitude extraction was then used to improve seismic visualization and find characteristics or anomalies associated with reservoir characteristics, including fluid connections, channels, fractures, and changes in porosity. The results of this investigation indicate that the D5000 reservoir has a limited potential for hydrocarbon recovery and accumulation in the Anyifield (Anyi-006) but a high potential in the Okoko field (Okoko-001). In order to maximize gas recovery from this significant reservoir, the results provide a better knowledge of the stratigraphic disposition of the reservoir, which will aid in better interpretation, lower drilling risk, and well-informed economic decisions. Additionally, this study's results confirm that seismic interpretation, velocity modeling, and attribute analysis techniques are trustworthy and efficient means of evaluating the Niger Delta's reservoir features and volumetric analysis
