EOS Import

In this section, we'll go through how you can import EOS models made in other softwares into whitson^PVT.

All fluid models created and imported, will be stored in the 'Fluid Models' tab on the navigation tab to the left. In the figure below, this tab is marked in gray (standard feature), while the 'Import' model button is marked in red.

Here, we see some columns with various information. the name of the fluid models is given, which Equation-Of-State was utilized, who was the creator for the model, when it was made, whether it is fully made and whether it is a useable model or corrupted (indicated by the green tick vs red warning sign). We could also set a fluid model as the 'Primary' model, which would tell us which of these models is the main one utilized.

When the 'Import' button is clicked, the following pop-up will generate.

In the pop-up, see that we have a list of inputs we can fill out (and these are required for consistency). Additionally, we see the list of file types that can be imported. If we do not have these files however, or encounter issues, we can download an Excel template and manually fill out the required information. The recommended approach would be to submit a support request if any such errors are enountered though, as it would be solved quickly, and permanently.

Supported File Formats

Currently, Excel files, ECL300, PVTp and PhazeComp files can be directly uploaded into the software, which will read the data and automatically convert the data into the whitson^PVT format. Note that for the Excel file, it would require whitson's own template, which is consistent for both whitson^PVT and whitson⁺, so this does not refer to any working Excel file.

The easiest method is usually therefore to upload an ECL300 file, as this could simply be generated in any other PVT software, then directly uploaded into whitson^PVT. This file type will work for both the full detailed parent model, as well as lumped child models.

Mapping Components

After clicking 'Save' on the 'Add Fluid Model' popup, a small calculation will be made. A second pop-up named 'Map Components' will then appear. This feature will recognize the components given in the model. Rather than just taking these for granted, we are given the option to select which components are corresponding to the fluid model components.

This is basically just a check, and we could readily automate this by clicking the 'Autofill' button. It is highly advisable to look through and make sure the components were properly recognized to avoid later problems though.

Once this has been saved, the EOS is fully uploaded into the software, and can be used for the various calculations found within!
