该研究利用3D地震数据和井下测井资料，通过直接指标划定了尼日尔三角洲地区烃类储层，并通过井震校正确认了这些储层与地震特征的一致性。解释后的井下数据揭示了A、B、C井的烃类富集区分别位于6450-6533ft、6449-6537ft和6629-6704ft，电阻率、饱和度和伽马射线测井数据共同界定。交叉图分析验证了岩性参数对储层饱和度的敏感性。最终，HD5000层被识别为含油储层。
摘要：
Hydrocarbon reservoir has been delineated and their boundaries mapped using direct indicators from 3-D seismic and well log data from an oil field in Nembe creek, Niger Delta region. Well log signatures were employed to identify hydrocarbon bearing sands. Well to seismic correlation revealed that these reservoirs tied with direct hydrocarbon indicators on the seismic section. The results of the interpreted well logs revealed that the hydrocarbon interval in the area occurs between 6450ft to 6533ft for well A, 6449ft to 6537ft for well B and 6629ft to 6704ft for well C; which were delineated using the resistivity, water saturation and gamma ray logs. Cross plot analysis was carried out to validate the sensitivity of the rock attributes to reservoir saturation condition. Analysis of the extracted seismic attribute slices revealed HD5000 as hydrocarbon bearing reservoir.
