Reservoir Characterization by Integration of Seismic and Production Data

Fluid production is altering initial reservoir properties and affects seismic wave propagation. Under certain circumstances those changes can be detected by seismic monitoring. Linking production to seismic is a challenging task, which requires good reservoir characterization both from static and dynamic sides. This paper, presents an optimized workflow, which allows early identification of dependency between reservoir performance and seismic. Described technique can be used as “fast track” approach for screening reservoirs, where seismic monitoring could be applied. Once correlation between seismic and reservoir performance is established, it could be further used as a reasonable justification for further petroelastic modeling. Results of the study have helped in identification of highly fractured zones, which act as a high permeability corridors, leading for fast water breakthrough. Additionally, it has been used to condition the history match results and plan infill wells.
