New Release


New Features:

  1. Added a third party XSOLVER. (much faster for black oil models)
  2. Co2 Sequestration/CO2STORE. (Three Phase EOS model only)
  3. Multiple EOS regions. (Compositional model only)
  4. Added Relperm End-Points: SWMAX, KRWCW, KRGCG array
  5. Injection of Steam(quality=100%)+N2 + CO2. (thermal model only)
  6. Well On Time Factor
  7. Wellbore Cross Flow
  8. 9-point formulations for black oil and compositional models

Major Bugs Fixed:

  1. Wrong results in Dual Porosity/dual permeability model using XSOLVER
  2. XYPLOT errors on rates, of Well, Group, Region and Field
  3. Oil Compressibility (Coil) = 0.0 in Multi-PVT regions. (black oil model only)
  4. Re-completion errors in schedule section
  5. Initialization errors of complex system
  6. ZVAR/KVAR reading errors
  7. Unit Conversion errors
  9. Plot errors of restarted run
  10. Restart error for Model with Metric Unit
  11. Oil Viscosity using correlations of AVISC, BVISC (thermal model only)


  1. Stability and CPU run time of Co2 injection (Compositional model only)

Software Customization Service

Because of EZSim's innovative and scalable architecture that allows any components appear and stay in any fluid phases (aqueous, oilec and vapour ), it can be extended and customized to more functions. Our customizations involve the following:

  • Changing the workflow, functionality, and processes of the product to fit specific business needs
  • Customizing visual aspects of the solution
  • Developing additional product functionality or capabilities

Whatever your reasons that will lead your choice, don’t forget that customized software can save money in the long run.
