Look out for our weekly "Software Tips" which provide some useful tips that could potentially
save you time and produce unexpected results at your fingertips. Contest details below.

Tip 5: Use Black Oil to Synthesize Assay in Petro-SIM 5

Question:

In some circumstances, you may have very limited compositional data for a fluid. Would you like to characterize a fluid by using the available data?

Answer:

Petro-SIM 5 includes a new assay synthesis method, which provides a way of constructing a compositional fluid model from limited data. This method is called Black Oil Analysis.

Procedure:

1.  The Black Oil Analysis is accessed from the Black Oil tab in the Oil Characterization Environment.

2.  You can Create Black Oil from laboratory data through synthesis via KBC's Multiflash™ technology. Minimum required input data includes gas gravity, stock tank oil specific gravity and solution GOR. The rest is optional. After entering the data, click on the Synthesize button. The green "Synthesis Complete" status bar   means that the synthesis was successful.

3.  In the PFD environment, assay can be loaded from pre-defined Black Oil as shown in the screenshot below.

4.  Alternatively, you can enter Black Oil source data directly in the stream in the PFD environment. Double click a stream, and at the bottom of the active window, find the oil barrel icon and choose Synthesize From > Black Oil. You will find the same input table as in Step 2.

5.  Cape-Open functionality allows you to import any fluids defined in Multiflash software, standalone version. The first step is to export  the fluid defined in Multiflash via Export CO Property Package and give the package a description.

6.  The property package can be imported via fluid package in the Simulation Basis Environment. In Fluid Pkgs tab, click on Add, then select CAPE-OPEN 1.1 in the property Package Selection window. In the CAPE-OPEN options window, select the fluid that you exported from Multiflash earlier, then click Accept. Then you are able to use this fluid package in any streams in the PFD.

UPCOMING CONTEST:
We will be checking on how well you do by asking some simple questions in December. Two lucky winners will be picked and receive KBC exclusive gifts. Do keep a look out for our periodic email.
