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...

Wellbore stability problems and stimulation operations call for models helping in understanding the subsurface behaviour and optimizing engineering performance. We present a fast, iteratively coupled model for the flow and mechanical behaviour that employs a time-sequential approach. Updates of pore pressure are calculated in a timestepping...

Subcritical crack growth can contribute to stimulation of permeability in geothermal reservoirs as it can lead to lower formation breakdown pressure and enlargement of fracture disturbed zone. This study examines tensile and shear failure due to fluid injection and axial compression in tight sandstones. The overall aim is to identify effects of...

Geothermal energy aids in achieving ambitions for the reduction of greenhouse gas emissions by contributing to a more sustainable energy mix. In particular, geothermal energy in the Netherlands can play an important role in providing a sustainable supply for domestic and industrial heat demand. However, just like with any large scale industrial...

Seismic events induced by the depletion of hydrocarbon reservoirs can cause damage to housing and cause societal and economic unrest. However, the factors controlling the nucleation and size of production-induced seismic events are not well understood. Here we used geomechanical modeling of production-induced stresses and dynamic rupture...

We implement a Coulomb rate‐and‐state approach to explore the nonlinear relation between stressing rate and seismicity rate in the Groningen gas field. Coulomb stress rates are calculated, taking into account the 3‐D structural complexity of the field and including the poroelastic effect of the differential compaction due to fault offsets. The...

Pore pressure changes caused by the production of gas from reservoir rocks result in reservoir compaction, stress changes on faults, potential fault reactivation and related seismic activity. This seismic activity is expected to be affected by the amount of pressure change, the spatial distribution of the pressure changes relative to the...

In the Netherlands, over 190 gas fields of varying size have been exploited, and 15% of these have shown seismicity. The prime cause for seismicity due to gas depletion is stress changes caused by pressure depletion and by differential compaction. The observed onset of induced seismicity due to gas depletion in the Netherlands occurs after a...

Understanding the mechanisms and key parameters controlling depletion-induced seismicity is key for seismic hazard analyses and the design of mitigation measures. In this paper a methodology is presented to model in 2D the static stress development on faults offsetting depleting reservoir compartments, reactivation of the fault, nucleation of...

Pressure maintenance by injection of nitrogen into a reservoir is one of the potential options to mitigate induced seismicity during gas production. It is expected that seismicity and the seismic hazard can be reduced by decreasing the stress changes and compaction associated with the declining pore pressure in the reservoir rocks. However,...

Geomechanical numerical simulations were conducted to analyze the stability of faults during gas production. A FLAC3D model of a fault intersecting a producing gas reservoir was developed which incorporates the fully dynamic behavior of the fault and surrounding rock mass, and a fault frictional behavior based on a slip-weakening law. The...

Satellite radar data were used to estimate subsurface model parameters of the Bergermeer gas field. Directly using combinations of the line-of-sight measurements in both ascending and descending satellite geometry provided an additional dimension in the data and avoided the introduction of errors during interpolation to horizontal and vertical...

Current methods which are used for seismic hazard analyses of production induced seismicity in The Netherlands are generally based on either empirical relations which link compaction strain and seismic release or simple relations between available fault area and seismic moment release.

A geomechanical and fluid-flow coupled model was developed to simulate natural-fracture-network reactivation during hydraulicfracturing treatments in shale gas reservoirs. The fractures were modelled using the continuum approach in a commercial finitedifference code, labeled the "softening ubiquitous joints" model, with randomly distributed...

We constructed a coupled model to obtain a better understanding of the role of pore pressure changes in causing fracture reactivation and seismicity during enhanced geothermal systems operation (EGS). We implemented constitutive models for fractures in a continuum approach, which is advantageous because of the ease of integration in existing...

Geomechanical simulations were conducted to study the effects of reservoir depletion on the stability of internal and boundary faults in gas reservoirs overlain by elastic and viscoelastic salt caprocks. The numerical models were of a disk-shaped gas reservoir with idealized geometry; they mimic the structure of a gas field in the northern...

A geomechanical modeling study was conducted to investigate stability of major faults during past gas production and future underground gas storage operations in a depleted gas field in the Netherlands. The field experienced induced seismicity during gas production, which was most likely caused by the reactivation of an internal Central fault...
