This format is ideal for use in cloud environments.
PVTSIM JSON EOS IMPORT
New import function for PVTSIM JSON EOS files.

FLUID MANAGEMENT
UPDATED EDITING OPTIONS IN FLUID EXPLORER
Bulk Edit functionality enabling easy editing of the name and sampling data for a selection of fluids.
Single menu for editing Common EoS models. Updates to the model will be applied to all fluids in the Common EoS model.
UPDATED COPY OF PVT DATA
When you copy PVT data from one fluid to another the Sampling Data will also be copied.
FLUID HANDLING
LUMP COMMON EOS MODELS
It is now possible to lump existing Common EoS models.
ASSIGN LUMPING TO IMPORTED EOS MODELS
Imported EoS models do not have PVTsim?s lumping information, which is required to run the ?Add to EoS? functions. The new Assign Lumping to EoS function allows the lumping information to be stored on the fluid, thereby enabling the use of PVTsim?s ?Add to EoS? functions for the imported EoS model.
OBM CLEANING ? USER CONTROLLED
Users can now select a measured OBM composition in the OBM Cleaning ? User Controlled menu. The amount of OBM removed can be changed with the slider, and the plot of the resulting clean composition can immediately be viewed.
When a measured OBM Composition is selected, users can press ?Find Optimum OBM amount?. This new function finds the amount of OBM to be removed to give the best trend line of the clean composition vs. carbon number.
The allowed range for the estimated OBM composition increased to C9-CNplus-2.
SIMULATIONS WITH OBM
When a fluid is selected with OBM components, simulation menus now display the amount of OBM in the fluid.
PVT SIMULATION & REGRESSION
IMPROVED LOGIC FOR NEAR-CRITICAL FLUIDS
For near-critical fluids with a measured Differential Liberation experiment, logic has improved so regression to the data can take place, even if the fluid becomes a gas condensate during the regression iterations.
IMPROVED CSP MODEL TUNING

DEPTH GRADIENT SIMULATION
Explicit location of GOC found when the starting sample is a gas and there is no distinct GOC, just a critical transition at a pressure higher than the saturation pressure.
FLOW ASSURANCE

Inner lines can be included in phase envelopes with water.
The Saturation Point option now allows the fluid to contain water and calculates all hydrocarbon and aqueous saturation points.
