NEW FEATURES AND MODULES IN PVTSIM NOVA 5.1

IMPORT OF PVT DATA

  • UPGRADE TO PRODML 2.1
    • The option for importing an XML file in PRODML format now supports PRODML version 2.1.
  • IMPORT OF PVT DATA FROM EXCEL SHEET
    • The option for importing an XML file in PRODML format has been upgraded to support automated import of PVT reports in a Calsep specified Excel format (Calsep Excel file).
    • It is also possible to convert a PVT report in “Calsep Excel file” format to a PRODML 2.1 XML file.

MODEL UPDATE

  • THERMAL CONDUCTIVITY OF AQUEOS PHASE
    • Hydrate inhibitors taken into account when calculating the thermal conductivity of an aqueous phase.

NEW INTERFACE MODULE

  • INTERSECT COMP
    • Interface to Intersect Compositional.

HYDRATE

  • HYDRATE PT CURVE
    • The hydrate PT curve option has been updated to handle a sudden shift in hydrate temperature from dew to bubble point side for a narrow boiling gas mixture.

FLASH

  • T-BETA AND P-BETA
    • Enhanced robustness of T-beta and P-beta flash options for mixtures with aqueous components.

UNIT OPERATION

  • 3-PHASE SEPARATOR
    • Logic changed to let water follow oil until last separation stage.

INTERFACES

  • ECLIPSE BLACK OIL
    • Refined monotonicity check.
  • INTERSECT BLACK OIL
    • Unit specification added to interface file.
  • GEM
    • GEM interface updated to support T-dependent volume shift parameters.
