Leveraging relative geological time models to enhance 4D seismic monitoring: Optimizing reservoir saturation analysis through delta time changes

This paper explores the innovative application of the Relative Geological Time (RGT) model in 4D seismic monitoring to analyze changes in reservoir saturation. By comparing reference and monitoring seismic volumes, the RGT model provides a temporal framework to interpret shifts in reservoir properties as a function of time. The difference in relative geological time between these volumes (Δt) serves as a proxy for understanding dynamic changes in saturation, thereby enabling more precise and timely decision making in reservoir management. This approach not only enhances the accuracy of 4D seismic data interpretation but also contributes to more efficient resource extraction and improved operational efficiencies in a digital landscape.
