CO2 Injection Monitoring: Enhancing Time-Lapse Seismic Inversion for Injected Volume Estimation in the Utsira Formation, Sleipner Field, North Sea

Doyin Pelemo-Daniels,
Basil O. Nwafor,
Robert R. Stewart

Abstract: This article presents an in-depth study of CO2 injection monitoring in the Sleipner Field, focusing on the Utsira Formation. The research leverages advanced time-lapse inversion techniques and 4D seismic data analysis to enhance the accuracy of volume estimations and provide a comprehensive understanding of the dynamic behavior of the injected CO2 plume. The analysis encompasses cross correlation, time shift, predictability, and other key elements to yield robust insights into the reservoir’s response to CO2 i… Show more

“…The fluid substitution models employed in this study were built using the calibrated rock physics model and Biot-Gassmann theories [30,44,45]. For the partial saturation in brine and supercritical CO 2 , an effective fluid phase with different average techniques, used as "one fluid phase" as an input into the Biot theory for saturated porous media, is used [46,47].…”
