Abstract

In this seismic inversion case study, we used a deterministic technique to improve subsurface understanding and reservoir characterization across the Qantara concession in Egypt's onshore Nile Delta. The region's diverse geology makes reliable resource assessment and recovery strategies difficult. We hoped to build quantitative property models that shed light on lithology, porosity, and fluid saturation by merging seismic data, well logs, rock physics models, and inversion techniques. The method included data preparation, calibration of rock physics models, and property inversion. The resulting property volumes, which included P-impedance, S-impedance, and density, were combined with previously collected geology and well data. The collaboration of geophysical, geological, and reservoir engineering disciplines improved our understanding of the reservoir's complexities. Uncertainty analysis shed light on the dependability of the inversion results, providing a thorough perspective of probable property variability. This research highlights the importance of deterministic seismic inversion in complex geological environments. We improve reservoir characterization and enable more informed decision-making for drilling and production operations by obtaining high-resolution property estimations. The incorporation of many data sources emphasises the significance of interdisciplinary collaboration in order to maximise the value of subsurface information. Finally, our deterministic seismic inversion approach applied to the Qantara concession demonstrates its efficacy in addressing geological difficulties and enhancing reservoir management. As the energy industry continues to deal with complex subsurface settings, this technology will be useful in optimising hydrocarbon recovery and decreasing exploration uncertainty.
