This task aims to run a petroleum reservoir simulation software named ATHOS Duration and Staff: 4 weeks + defence.

CSUA.1: Testing the working of ATHOS, especially SIMVIEW, using the previous tasks. CSUA.2: Making a command file of a simple case CSUA.3: Simulation of the case CSUA.4: Visualisation of the results using SIMVIEW

Use of a petroleum reservoir simulator

Our two studies have been interested on discovering simview options and working. Using the simview manual, we learned how data are organized and managed, using the different modules of the software. To put what we learned into practice, we decided to implement the example described in the tutorial.
The second session of our favorite New Codes Workshop was more Athos focused. We finished the example and moved to the software execution part. We also got some results plotted.

Now that both Simview and Athos have been explored, we will try to simulate more practical case that could be the interest of a real project. This is the aim of the last session called A Complete Simulation Using ATHOS.

We have already used the simview interface to include a case. This required to import a quantity of files during the simview part.
In this case, we just have one file (.edo), written in a key-words language. It contains different data that describe the site we simulate. So we cannot follow all the steps we have followed in Simview building: we do not posssess all required files (.int, .sdo, etc...). So starting a new project the way we did when running the example provided with Athos. We must find another way to incorporate data into Simview database and run Athos using it.

What you need:    A file containing the careacteristics of the field you want to simulate. This should be a .edo file.
Work : Follow the steps presented below :
Choose an existing project of which you do not need the results anymore.
Click on the case. You display the contextual pop-up menu : 4 hierachic levels appear. The aim is to                     destroy "Result grids" and "Simulated production", in order to build new ones. For both of them,                     make a long click with the right mouse button. Select delete and confirm the operation when                     requested.  
                 Now your case is ready : it exists for the software, but at the meantime, you can load the simulation                  you need to accomplish.
Go to Initial-grids under <Case>and make a long click using the right mouse button. We you acess to basic, click again and go to SIMViewToAthos. In the space labelled Main file, enter Your .edo file.
Launching the case: Move your cursor to <Case: ...>. Make a long click on it, ans choose RunAthos option. You will get to a new window. In the upper part of this window, enter the name of your file without the edo extension and do not forget to presse Enter in your keyboard. This will only be used as a common prefix for other variables. Highlight in red the bottons in front of Pre, pro and post, so that the three sections pre, pro and post processing are done in this order. Switch on the bottons next to "Load simulation results" and "Load grid results".
You are now ready to go. Just click on Run. Your simulation finishes when the cursor comes back to its "normal" form. You can exit by asking to. You will also have to confirm your choice.
Loading the simulation results:  click on <Case:...>. Then go to AthosToSIMView level. Browse and look for the .int1 file in your working directory. It should have the same name as your .edo file. Confirm your choice by "Select". Overwrite "Dol_Injection" by a word, which will be used later for the XY plot of simulated results. I advise you to give it a special name, such as your dog name, or your favorite actor's, or... whatever. Just somehting you can identify during the rest of the operations.
Now is the "Heure de vérité": click on import. If your operation is sucessful, two new hierarchic levels will appear under the case of the databrowser: "Result grids" and "Simulated production".

If my descritption did not convince you, if it is not enough clear for you, just forget everything and refer to the simview user's guide on page 200. Check it out, it is great.

Choose the module XY plot in the contextual pop-up menu displyed when you click on Simulated production level. You enter to this new window. Automatically, the values you will plot concern the last simulation you realized. Unless you open a .xy file already drawn.

In the extreme left of the XY plot window, a vertical band composed by different buttons is available. Click on Graph and move to the white zone to delimitate the graphic space. To do this, click anywhere with the mouse, handle it and leave it when the cadre is what you expect.

Now, you need to put the right values on the Y-aixs. Click twice on it. You will display a window.

You need to set two things:

Add: Choose whatever you need (for example FL1, ..., FL8) and click on Add. Finish by Done.

List: located under Parameter : select just one displayable vlaue.
