Eclipse - or not¶
In the very first versions of ERT it was all about running Eclipse - there was no general forward model. The concept of general forward model came quite quickly and since then the special treatment of Eclipse has gradually been reduced. It is now possible to run a forward model without Eclipse at all, but ERT is still quite far from a situation where Eclipse is just any other forward model. For good and for bad there is quite a lot of functionality in ERT which is specifically targeted at Eclipse.
Eclipse keywords¶
DATA_FILEThis is the name of ECLIPSE data file used to control the simulations. The datafile used with this keyword should be prepared for use with ERT, and will generally not be a 100% valid ECLIPSE data file:
-- Load the data file called ECLIPSE.DATA DATA_FILE ECLIPSE.DATA
The preparations you should do to this file include:
- You should insert
INCLUDEstatements to include the various uncertainty parameters in use at the right place in the datafile. - You must make sure that the include files used in the datafiles can be correctly resolved from the runpath location.
- See the
DATA_KWkeyword which can be used to utilize more template functionality in the eclipse datafile.
When actually running the simulations the file given with the
DATA_FILEkeyword will be used as a template, and a realization specific datafile will be written to the runpath folder, the name of this file is given by the ECLBASE keyword.- You should insert
ECLBASE- This is the name of the eclipse simulations which will be generated by ERT,
the
ECLBASEargument should typically contain a%dformat specifier, which will be replaced with the realisation number when ERT creates the runpath directories:
ECLBASE eclipse/CASE_%d
Observe that it is possible to add a leading directory part to the ``ECLBASE``
setting as illustrated above; the directory ``eclipse/`` will be generated as
a subfolder in the runpath directories.
GRID- This should be the name of an existing GRID/EGRID file. The main use of the
grid is to map out active and inactive cells when using
FIELDdata. If you do not useFIELDdata you do not need theGRIDkeyword. The grid argument will only be used by the main ERT application and not passed down to the forward model in any way. SCHEDULE_FILE- DEPRECATED!
