• PVTsim Nova from 3.0 to 3.1

Updates and Bug Fixes

GENERAL

  • OPEN DATABASES OF OLDER FORMAT
    • Option to open PVTsim Databases of versions 19-21 reintroduced.

FLUID HANDLING

  • RECOMBINE
    • Lumping kept when two common EoS fluids are recombined.
  • DELUMP
    • Inconsistency between CPA and SRK parameters corrected.
  • CHARACTERIZED REGRESSION
    • Characterized regression updated to support tuning on Vc to match viscosity data points.

PVT & RESERVOIR

  • DEPTH GRADIENT
    • Bo and Bg included in output datasheet and plot.
  • VISCOSITY DATA FOR GAS CONDENSATES
    • Simulation of and regression to viscosity experiments are now allowed for gas condensates.

FLASH & PROCESS

  • H2S
    • Column header for H2S partition coefficient corrected from Aq/Liq to Liq/Aq.

FLOW ASSURANCE

  • FULL ASPHALTENE PHASE ENVELOPE
    • Minimum temperature for Full Asphaltene Phase Envelope can now be defined by the user.
    • Critical points are now output with Full Asphaltene Phase Envelope.
  • DEPOWAX
    • Simulation time was reported wrong in the output when time was in the unit of Day(s).
  • SCALE
    • Output concentrations of CO2 and H2S corrected.

INTERFACES

  • ECLIPSE COMPOSITIONAL IMPORT
    • Eclipse files imported incorrectly in some cases in PVTsim Nova 3.0.
  • OLGA COMPOSITIONAL TRACKING
    • Save Fluid function modified to save characterized fluid instead of plus fluid.
