Geothermal Modelling​

France reservoir model

JRG Energy’s reservoir modelling team brings together subsurface specialists — including geoscientists, hydrogeologists, and reservoir engineers — supported by senior consultants with over 35 years of experience in geothermal resource development across more than 20 countries.

Together, our team delivers integrated modelling solutions that combine geological, geophysical, and geochemical datasets to optimise resource development, support well targeting, and forecast asset performance under varying production and reinjection scenarios.

We provide end-to-end modelling services using industry-leading software (Leapfrog Energy, Seequent Central, Waiwera, Volsung, Gudrun) covering conventional hydrothermal systems through to enhanced and closed-loop geothermal developments, including but not limited to:

  • Geological and conceptual modelling with Leapfrog Energy
  • 3D structural modelling and MT/Gravity inversions
  • Resource assessment and capacity estimation
  • Numerical reservoir modelling and natural state simulations
  • Production and reinjection forecasting
  • Well testing program design, supervision, and QA/QC
  • Pressure Transient Analysis (PTA) and PTS interpretation
  • Feed zone identification, enthalpy estimation, and skin/boundary analysis
  • Wellbore modelling (standalone or fully coupled with reservoir models)
  • ESP and LSP integration in wellbore models
  • Decline analysis and field performance monitoring
  • Peer review and QA/QC of existing geological and reservoir models
  • Data room creation and management
  • Resource and steamfield management review
  • Capacity building, training, and technology transfer
