A new setup to study the influence of plant growth on the consolidation of dredged cohesive sediment

Dredged cohesive sediment is progressively being used for wetland construction. However, little is known about the effect of plant growth during the self-weight consolidation of this sediment. In order to check the feasibility of such a study, a new experimental setup has been constructed. As an example, the effect of Phragmites australis on the...

Effects of fault transmissivity on the potential of fault reactivation and induced seismicity: Implications for understanding induced seismicity at Pohang EGS

Enhanced Geothermal Systems (EGS) involve hydraulic stimulation of the permeability of deep low-permeable rock formations. This causes the reactivation and opening of pre-existing natural fracture networks and the formation of new fractures. During hydraulic stimulation, injection pressures at the bottom of the injection well can reach...

The impact of viscoelastic caprock on fault reactivation and fault rupture in producing gas fields

Pressure prediction and hydraulic continuity - Regional trends and local anomalies

This paper discusses the influence of hydraulic continuity of reservoirs and faults and the lack thereof on the occurrence of local pore fluid pressure conditions deviating from previously established regional trends. The hydrodynamic-based approaches will be illustrated with case studies from the Netherlands, in particular.

Parametric Nonlinear Regression Models for Dike Monitoring Systems

Dike monitoring is crucial for protection against flooding disasters, an especially important topic in low countries, such as the Netherlands where many regions are below sea level. Recently, there has been growing interest in extending traditional dike monitoring by means of a sensor network. This paper presents a case study of a set of pore...

The mechanical impact of CO2 injection

The mechanical impact of CO2 injection into a depleted hydrocarbon field or aquifer is caused by changes in the stress field, resulting from changes in the pore pressure and volume of the rock. Mechanical processes can lead to the loss of reservoir and caprock integrity, and the reactivation of existing faults. A geomechanical numerical...

Estimating regional pore pressure distribution using 3D seismic velocities in the Dutch Central North Sea Graben

The application of the empirical Eaton method to calibrated sonic well information and 3D seismic interval velocity data in the southeastern part of the Central North Sea Graben, using the Japsen (Glob. Planet. Change 24 (2000) 189) normal velocitydepth trend, resulted in the identification of an undercompacted and overpressured zone within the...
