INTEGRATED RESERVOIR CHARACTERIZATION: A CASE STUDY OF AN ONSHORE RESERVOIR IN NIGER DELTA BASIN
Abstract:
Reservoir characterization plays a crucial role in the successful development and production of hydrocarbon reservoirs. This study presents an integrated approach to reservoir characterization, focusing on an onshore reservoir located in the Niger Delta Basin. The Niger Delta Basin is one of the most prolific hydrocarbon basins in Africa, known for its complex geological and reservoir heterogeneities.
The objective of this study is to demonstrate the effectiveness of integrating various geoscience and engineering disciplines in characterizing the reservoir and understanding its geological and petrophysical properties. The integrated workflow encompasses seismic interpretation, well log analysis, core data analysis, and reservoir modeling techniques.
Seismic interpretation forms the foundation of this study, providing insights into the structural framework and stratigraphic architecture of the reservoir. The seismic data are used to identify faults, fractures, and other structural elements that can impact reservoir performance.
Well log analysis plays a crucial role in understanding the reservoir’s petrophysical properties, such as porosity, permeability, and fluid saturation. Various well log measurements, including resistivity, gamma-ray, and sonic logs, are analyzed to estimate these properties across the reservoir interval.
Core data analysis provides direct measurements of rock properties and allows for the calibration of log-derived interpretations. Core samples from representative intervals are analyzed for porosity, permeability, lithology, and fluid properties. Integration of core data with well log data enhances the accuracy of the reservoir characterization.
Reservoir modeling techniques are employed to build a three-dimensional (3D) representation of the reservoir, incorporating all available data. The reservoir model incorporates the interpreted seismic data, well log interpretations, and core analysis results. It enables the visualization and quantification of reservoir properties, facilitating reservoir management decisions.
The integrated reservoir characterization workflow presented in this case study provides a comprehensive understanding of the onshore reservoir in the Niger Delta Basin. The results contribute to improved reservoir management, including optimal well placement, enhanced hydrocarbon production, and improved field development strategies.
The findings from this study can be applied to similar onshore reservoirs in the Niger Delta Basin and other hydrocarbon basins worldwide, aiding in the efficient utilization of hydrocarbon resources and mitigating exploration and production risks.
