After Gas: Exploring a Design Framework for the future of new perspective in Groningen after the closure of gas field

This research focuses on the transformation of the Groningen gas field region, which has transitioned from a symbol of national pride due to its vast natural gas reserves to a region grappling with the significant impacts of gas extraction. With the permanent closure of gas production, the region faces ongoing challenges such as land subsidence,...

Fault intersection and induced seismicity: the effects on the induced stress field and the dynamic rupture, and their implications

Intersecting faults are often ignored in the geomechanical simulation of induced seismicity. To investigate the effects of fault intersection and the resulting reservoir geometry on induced seismicity, caused, for instance, by gas extraction, we have developed 3D geomechanical models considering two intersecting normal faults and the...

Linking geomechanical simulation of induced seismicity to surface seismic observations: Simulated finite fault rupture to moment tensor inversion

Dynamic geomechanical modeling can generate the seismic wavefield caused by a fault rupture. In dynamic fault-rupture modeling, the source is considered to be finite, with a limited extent both in space and in time. This contrasts with the definition of a point source, which is generally assumed to explain the seismic wavefield caused by an...

Monitoring changes in the Groningen subsurface using non-physical arrivals in seismic interferometry

Seismic interferometry (SI) refers to the principle of generating seismic responses by crosscorrelating seismic observations at different receiver locations. Theory requires that the boundary sources emit the same energy, have regular spacing and are spaced densely enough. When these assumptions are not met, not only the desired physical...

Seismic Slip-Pulse Experiments Simulate Induced Earthquake Rupture in the Groningen Gas Field

Rock materials show dramatic dynamic weakening in large-displacement (m), high-velocity (∼1 m/s) friction experiments, providing a mechanism for the generation of large, natural earthquakes. However, whether such weakening occurs during induced M3-4 earthquakes (dm displacements) is unknown. We performed rotary-shear experiments on simulated...

Groningen Gas Field: Heterogeneities characterization of the sediments,by log evaluation.

This research focuses on the analyze of the heterogeneity of the Groningen gas field, i.e. characterization of the reservoir rock and the sealing Zechstein salt on top of the reservoir, by modeling the rock properties of the formations. The aim of this study is twofold, namely to characterize the thickness, shale content and porosity of the...
