Marchenko-Based Target Replacement, Accounting for All Orders of Multiple Reflections

In seismic monitoring, one is usually interested in the response of a changing target zone, embedded in a static inhomogeneous medium. We introduce an efficient method that predicts reflection responses at the Earth's surface for different target-zone scenarios, from a single reflection response at the surface and a model of the changing...

Studying CO2 storage with ambient-noise seismic interferometry: A combined numerical feasibility study and field-data example for Ketzin, Germany

Seismic interferometry applied to ambient-noise measurements allows the retrieval of the seismic response between pairs of receivers. We studied ambient-noise seismic interferometry (ANSI) to retrieve time-lapse reflection responses from a reservoir during CO2 geologic sequestration, using the case of the experimental site of Ketzin, Germany. We...

Quantifying Seismic Time-Lapse Effects of Solution Salt Mining - A Feasibility Study

In the northern part of the Netherlands the (magnesium containing) salt minerals carnallite and bischofite are extracted using solution mining methods, such as squeeze mining. As a consequence subsidence up to the surface is taking place, potentially causing harm to the environment. Given this fact the local government allows extraction of this...
