Tempest PVTx

Tempest PVTx is a fluid analysis package that tunes the equation of state using laboratory data.  It exports oil and gas data in a form suitable for reservoir simulation, or to other systems, such as METTE or the Roxar multiphase flow meters.


  • Import and display the results of common laboratory experiments, such as Constant Composition Expansion, Constant Volume Depletion and Differential Liberation Expansion.
  • Handle several fluid compositions simultaneously.
  • Tune the equation of state to give an accurate prediction of fluid properties, such as density, viscosity and formation volume factor.
  • Output black oil and compositional tables for common simulators.
