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
