“…Hence, there is no need to extrapolate the reflection response back to the surface. This is in contrast to earlier work where the regular Green's functions were used (van IJsseldijk and Wapenaar, 2021).…”

“…However, these results indirectly benefit from the isolated result, because the windows, which are used to identify the primaries, are selected from the isolated results (Figure 5C). Moreover, previous results by van IJsseldijk and Wapenaar (2021) show that the correlations from R abc are insufficient to get accurate time differences in less complex models with overburden events interfering with the primaries.…”

“…Inspired by this principle of coda-wave interferometry, Wapenaar and Van IJsseldijk (2020) show how correlation of multiples improve the ability to detect small changes in velocity compared to correlation of primaries. This method is then adapted to find changes in lateral varying media (van IJsseldijk and Wapenaar, 2021). In this work we further develop the method in order to account for time-lapse changes in the overburden.…”

“…First, equations (1) and ( 2) are used to find the extrapolated Green's functions with a focal level between overburden a and target zone b. Using these Green's functions, a reflection response free of overburden interactions can be acquired by solving (Wapenaar et al, 2021):…”

“…If the second focal depth is chosen just below the reservoir, the final result has effectively isolated all primaries and multiples of the reservoir. This isolated response can then be used to more accurately retrieve time-lapse traveltime shifts due to changes in the reservoir by cross-correlating baseline and monitor responses (van IJsseldijk and Wapenaar, 2021;van IJsseldijk et al, 2023).…”

The data-driven Marchenko method is able to redatum wavefields to arbitrary locations in the subsurface, and can, therefore, be used to isolate zones of specific interest. This creates a new reflection response of the target zone without interference from over-or underburden reflectors. Consequently, the method is well suited to obtain a clear response of a subsurface reservoir, which can be advantageous in time-lapse studies. The clean isolated responses of a baseline and monitor survey can be more effectively compared, hence the retrieval of time-lapse characteristics is improved. This research aims to apply Marchenko-based isolation to a time-lapse marine dataset of the Troll field in Norway in order to acquire an unobstructed image of the primary reflections, and retrieve small time-lapse traveltime difference in the reservoir. It is found that the method not only isolates the primary reflections but can also recover internal multiples outside the recording time. Both the primaries and the multiples can then be utilised to find time-lapse traveltime differences. More accurate ways of time-lapse monitoring will allow for a better understanding of dynamic processes in the subsurface, such as observing saturation and pressure changes in a reservoir or monitoring underground storage of hydrogen and CO 2 .

Reservoir simulations for subsurface processes play an important role in successful deployment of geoscience applications such as geothermal energy extraction and geo-storage of fluids. These simulations provide time-lapse dynamics of the coupled poromechanical processes within the reservoir and its over-, under-, and side-burden environments. For more reliable operations, it is crucial to connect these reservoir simulation results with the seismic surveys (i.e., observation data). However, despite being crucial, such integration is challenging due to the fact that the reservoir dynamics alters the seismic parameters. In this work, a coupled reservoir simulation and time-lapse seismic methodology is developed for multiphase flow operations in subsurface reservoirs. To this end, a poromechanical simulator is designed for multiphase flow and connected to a forward seismic modeller. This simulator is then used to assess a novel methodology of seismic monitoring by isolating the reservoir signal from the entire reflection response. This methodology is shown to be able to track the development of the fluid front over time, even in the presence of a highly reflective overburden with strong time-lapse variations. These results suggest that the proposed methodology can contribute to a better understanding of fluid flow in the subsurface. Ultimately, this will lead to improved monitoring of reservoirs for underground energy storage or production.
