PVTSIM Nova 3.1 cracked version

• COMMON EOS
  • Sampling data preserved on fluids resulting from Common EoS operations.
• QC
  • Refined OBM check in QC module.
• LUMPING
  • Two additional lumping schemes designed for use with gas condensates are included in PVTsim Nova 3. One is for heavy lumping of the fluid, the other is for normal lumping. The new gas condensate lumping schemes can be selected from the Lumping Schemes drop down menu on the Lumping tab.
  • PVTsim Nova 2.0 would crash at upstart if the user had set a custom lumping scheme as default in PVTsim Nova 1. PVTsim Nova 3 will reset a Nova 1 custom default lumping scheme to PVTsim default.
• FLUID VIEW
  • On rare occasions users were getting a message saying they had to enter text in one of the fields Well, Test, etc. on the Fluid View even though they had input text. That is no longer happening.
  • n-Paraffin tab only visible when checkbox is checked.
• DENSITY CHECK
  • Refined check for too low C7+ densities input

MODELS

• CPA SOLVATION
  • Full solvation matrix implemented, allowing solvation between any component pairs, including asphaltene components.
  • Pal & Rhodes emulsion viscosity results were incorrect when the water volume fraction for a relative viscosity of 100 was higher than inversion point. This bug has been corrected.

MODEL IMPROVEMENTS

• CPA PARAMETERS
  • The following additional components can be used with CPA: EtOH, MEG, DEG, and TEG.
• HV PARAMETERS
  • EtOH HV parameters updated.
  • SRK HV interaction parameters for C1-ZnBr2 updated.

PVT & RESERVOIR

• COMPARE WITH DATA
  • Simulated phase envelope plotted for comparison with experimental saturation pressures.
• PVT SIMULATIONS
  • CVD output updated to show correct residual oil PT conditions.
  • Input of gas composition enabled for Diff Lib stage at standard conditions.

FLASH & PROCESS

• PHASE ENVELOPE
  • Robustness of search for 3-phase area and for simulations with CPA improved.
• PROPERTY GENERATOR
  • Phase identification updated to correctly handle systems with only aqueous components.

ASPHALTENES

• ONSET PRESSURES
  • Improved calculation stability of Asphaltene PT curve and Asphaltene Pressure options.

FLOW ASSURANCE

• HYDRATE
  • Minimum inhibitor option updated to return amount of each inhibitor component for multi-component inhibitors.
• DEPOWAX
  • DepoWax Case Explorer can now be reached using the keyboard shortcut Ctrl+Shift+W.
  • DepoWax cases can now have names up to 80 characters long.
  • Bug corrected which caused incorrect wax deposition profiles in simulations with source fluids when either feed or source fluid(s) contained defined component(s) not in the other fluid(s).

OPEN STRUCTURE

• OPEN STRUCTURE WAX
  • Updated to correctly handle systems with only two phases present.
• OPEN STRUCTURE HYDRATE
  • Updated to correctly handle systems with a free salt phase and systems with more than four phases.
• OPEN STRUCTURE SAMPLES
  • New Open Structure sample for Separator Conditions Optimization added to the Open Structure Launch Menu.

INTERFACES

• OLGA & LEDA Flow
  • Default for IntelliGrid increased to 100×100 points. IntelliGrid allowed for all tables having at least 50×50 points.
  • Bug corrected, which would influence results when Cn-dep (T-dep) mixing rule used.
  • Number of Specific Pressure and Temperature points input in OLGA Wax no longer have to be equal.
• PIPESIM
  • Header lines removed causing problems when reading PVTsim generated tables in Pipesim.
• NEXUS
  • “Saturated properties” above the saturation pressure of the reservoir fluid generated by adding gas/condensate instead of using “constant composition extrapolation”.
• ECLIPSE BLACK OIL
  • K-factor and Split-factor input echoed in Rv/Rs vs. Depth table.
  • Eclipse Black Oil interface updated to output PVDG properties for pressures below saturation pressure for oil mixtures.
  • Eclipse Black Oil interface option extended to support saturated and undersaturated properties for all input pressure stages.
  • Default number of equidistant pressure stages set to 29. That is to avoid Eclipse introducing “negative oil and gas compressibilities” by interpolation in PVTsim generated tables.
• PROSPER/MBAL
  • Calculation of Bg in Prosper and Mbal interfaces updated to comply with specification from vendor (Petroleum Experts).
  • Prosper/Mbal interface updated to support extended output format in addition to the standard format. The extended format outputs more properties, which will ensure more consistency with PVTsim, but requires some manual input in Prosper/Mbal.
  • Prosper EoS interface updated to display more digits to always be consistent with PVTsim.
• HYSYS
  • Direct import of Hysys interface files from PVTsim into Hysys available from Hysys 8.8 CP1.
  • Bug corrected, which would influence results when Cn-dep (T-dep) mixing rule used.
• CHC FILE EXPORT/IMPORT
  • The CHC file format present in PVTsim 21 and earlier has been reintroduced. CHC files can be written from the OLGA Comp Tracking option and imported from OLGA Comp Tracking Import option.

OTHER

• Communication with network suppressed when PVTsim accessing Sentinel Superpro dongle. Otherwise network communication may cause malfunction of dongle.
• New density unit: pounds per gallon.
• Installation package for Open Structure 64 bit updated to install Open Structure 32 bit correctly.
