The simulation library contains all functionality directly related to running reservoir simulations, e.g. interfaces to simulators and tools for writing simulator driver files.

FieldOpt assumes that the input driver file is one single file. If incudes are used. this may cause big problems.

FieldOpt assumes the following folder structure:

somefoldername
├── somedrivername.gprs
└── include
    ├── otherfile.in
    ├── wells.in
    └── tsteps.in

The folder and driver name does not matter, but the folder containing the driver file must contain a folder named include which contains at least the wells.in and steps.in files. Any other files in the include will be copied along, but their content is ignored by FieldOpt.

The wells.in file must set (or include files that set) the keywords

• WELSPECS
• COMPDAT
• WCONPROD
• WCONINJE (for injectors)
• WELLSTRE (for injectors)

The tsteps.in file should contain any time steps at the end of the file (i.e. the time steps determining the duration of the simulation after the last control). These may be replaced by FieldOpt.

The primary driver file must have the following structure:

OUTPUT
    HDF5 TIME    CASENAME/
/

--
-- body...
--

INCLUDE
    ./include/wells.in
/

INCLUDE
    ./include/tsteps.in
/
