The field scale reservoir and overburden are 3D structures with complex material and stress states that cannot be accurately described by traditional 1D methods; Elfen horizon ensures that the geomechanical aspects of the reservoir receive as much attention as the fluid flow is given – and more: cap rock integrity, fault reactivation, induced seismicity, in-situ stress prediction, sub-salt, subsidence/compaction, etc…

  • Static and Dynamic Reservoir Field Scale Modelling
  • Fully coupled to reservoir simulators
  • Reservoir compaction, subsidence, fault reactivation
  • Complex salt structures, stress and material state

Modelling Capabilities

  • Large scale – multi field models – up to 20 million elements with the ability to sub-model to wellbore scale
  • Fault systems represented discretely
  • Non-linear elastic and plastic properties
  • Integration of input and output with 3rd party software packages
  • Detailed well trajectory assessments
  • One-way or fully coupled to reservoir simulators
