Black Oil Tables

There are two ways of navigating to the 'BOT Generation' page. The first is an option from the 'Detailed Model' page shown after saving a newly developed EOS, while the second is simply to utilize the left navigation bar and clicking on the BOT Generation page itself. See the buttons marked in red below.


Inputs

Once you are looking at the BOT Generation page, you will have some options regarding the reservoir properties (Input Data) surface processing, and the extrapolation type.


The first selection we have to make, is to choose what fluid composition we should utilize. We could choose to utilize one of the digitized sample compositions, or to use a custom composition through the 'Feed Composition' dropdown button.


The 'Custom Composition' button will alter the menu to look like the following figure when 'SAVE' is clicked. The new button marked in red would open a pop-up to fill in a custom composition


The software will auto-select a digitized sample for us when entering the page, so for testing purposes, we could simply use this sample's composition. Once we have decided on a composition, the next part would be to fill in reservoir pressure and temperature, and the associated surface processing.

Finally, we have the option to extrapolate the BOT, using either incipient gas or a custom composition.


With all parameters decided on, we can generate our BOT.

Results

The following figure shows the table that has been generated using the associated reservoir conditions for the sample selected.


Export

If we are satisifed with our black-oil table, we can go ahead and 'STORE' this in whitsonPVT for later use or export to simulation files. We can see that this black-oil table will be stored within the associated EOS model it is derived from.


Now, another tab has popped up, named 'EXPORT FILES'.


Here, we can select between Eclipse, Kappa, Resfrac, Excel and a wide range of other simulation software file types.

We also have the option of chosing between the PVTO (wet gas) and PVDO (Dry gas) formats.

When clicking 'SAVE', a file will be generated that is available for download with the arrow button shown below.


Next Steps

Having successfully generated a black-oil table, we could take a look at creating lumped compositional tables!
