Quick reference guide
of SIMView software :
SIMView is a sophisticated complete environment designed for achieving
simulations of fluid flows in reservoirs.
11 applications work together to realize SIMView.
The XY Plot Viewer
The 2 Grid Viewer
The Reservoir Mesh Builder
The Matrix Editor
The Table Editor
The loader : ATHOS to
Grid to SIMView
Measures to SIMView
SIMView to ATHOS
The main application : Data
Input data are integrated.
Basically, they concern field geology, including thinknesses, porosities
and permeabilities of the field material. Using the Reservoir
Mesh Builder application, rectangular cartesian grids are set
up. They can be refined until 10 times. A 2D and 3D visualization of the
grid is possible. Its content can also be displayed by the Matrix
Then, flows can be simulated.
Output data will be mainly
simulated production of oil, organized in items. They can be edited
as tables. Production data can be displayed by the Table
Editor and studied by the XY plot Viewer
graphical tool. The last module offers the possibility of personalizing
data representation (simple/composite plot style, colors, legends, etc)
Exchange of data between SIMView and other applications is accomplished
ATHOS to SIMView brings
ATHOS calculation results
Grid to SIMView brings grids
Measures to SIMView is used
to import oil production results.
ATHOS can be directly run from SIMView be using Run
Organization of data:
Under each project, you can open several fields. Under a given
field, there is a resevoir that can contain different studies. Each study
often includes some cases.
Once you are in the diretory where SIMview is executable, type
the comand simview.
A dialogue window appears: this is the SIMview Data Browser.
The Help button
(top right) makes a link with Athos user guide. It actually opens and edits
SIMview.pdf file, in the arbrocat reader.
By cilcking on Project,
two buttons appear down: Open and Quit.
Quit is to close the data browser.
When you open a project, a dialog box lists available databases.
One at least is already selectable: demoDB. It is a prepogrammed database,
which gives a variety of examples showing the kind of cases the software
Very interesting with ATHOS: a possiblity of contacting the code's
support is offered. To access to this opportunity, simply click on the
button hepl from the data browser window. keep the mouse pushed down. Then
two options appear. Select contact our support and fill out the
Building your own case:
If you want to realize yor own simualtion, with its proper characteristics
you can follow step by step the SIMView tutorial, which is
deltailed on page 178 of the simview.pdf help file. A brief description
is though given here.
field, importing layers characeteristcs. Grid To Simview module
First step :
Hirachicly create a field, a reservoir, a study and a case. Once the last
level exist, different tasks can be launched. Your field will be composed
by 5 layers.
Second step :
Import data files containing tutorial information about the field.
For each layer, you will need: gross thikniss (GT.ascii),
porosities (POROS*.ascii), horizontal permeabilities (KX*.ascii). For the
top layer (number 5) you will also have to get depth values(TOP.ascii).
These files are contained in the directory examples, under the sub directory
Grid To SIMVEW. Examples should be located in your working account.At this
same step, you will intialize x-axis and y-axis dimensions. Make the initialization
of layers geological properties:
You are requested to name your geometry file.
You must also give a grid name a relatively to your reservoir. You
Previously imported different data files to the field. Here, you will assign
values of data (gross thiknesses, horizontal permeablilities, and porosities)
to the matching layer. Lastly, you can use the matrix editor module to
affect vertical to horizontal permeability ratio(called: "Z to H cell
permeability"), trap zonation, rock end points zonation, and net thikness
(same names). Here again, stricltly respect values provided by simview
tutorial. When these intializations are all done, the root grid contains
with all the parameters it needs to launch simulations via ATHOS.
First of all, create a grid.
You can also chek if the diplays of DX and DY are correct (12000ft*12000ft).
If not, destroy all the study you are working on, and make intializations
once again. Operations are completely irreversible in Simview: each time,
you have to check that imported datat is correctly done before confirming
operations and quitting dialog windows.
Once you have finished with
the subgrids, the grid system is done. You can edit the grids to vizualise
what imported, this will look like the picture below:
To simulate, you will simply
have to run ATHOS, via RUN ATHOS command. Different types of
simulation resulats are available.
