Integrated 3D geomechanical modelling for deep subsurface damage. A case study of tectonic and man induced damages in the eastern Netherlands

Current advances in finite element computer codes and increase in computer power theoretically allow quantitative modelling of the geomechanical effects of hydrocarbon depletion from reservoirs. Here we show that it is technically possible to incorporate the full complexity of the 3D geological structure of a reservoir including faults into...

Building a 3D geomechanical model of a gas field for geohazard prediction

Land subsidence, triggered earthquakes and wellbore instabilities are some examples of geohazards caused by or related to the production of subsurface natural resources and storage of energy residues in the deep subsurface. The main objective of geomechanical modelling is to effectively predict surface and subsurface deformation and damage due...

Modelling of deep subsurface for geohazard risk assessment.

Exploitation of subsurface natural resources, and subsurface storage of energy residues, may cause subsurface and surface deformation and damage to property. Deformation is generally difficult to assess and prove, although economical, environmental and societal interests are huge in terms of strain on granting concessions, (potential) damage...

Geomechanical modelling of the induced seismicity for a gas field

Gas production from a reservoir may lead to reactivation of nearby faults, which is likely to cause local seismic events. This paper is focusing on the calculations of stress evolution during depletion of a gas reservoir in order to investigate the possibilities for the reactivation and slip on normal faults, thrust faults and bedding planes at...
