reservoir simulator

Simulation of reservoir fields come in many forms, but for the purposes of res2df we only consider simulators that take a deck as input and produces output files such .UNSRMY. This includes, OPM flow and Eclipse.

.DATA file

Input provided to reservoir simulators such as Eclipse or OPM Flow. Often a .DATA file includes other include files with the INCLUDE keyword.

include file

Files that provide inputs to reservoir simulators by using the INCLUDE statement in .DATA files. By convention, these files often have the extension .INC/.inc (generally) or .GRDECL/.grdecl (for files included into the grid section).

deck

Refers to inputs passed to reservoir simulators. It may be a .DATA file and the include files it points to, or it may be a single or several include files. If a deck contains all the information (i.e., keywords) the simulator needs to run the requested simulation, it is defined as complete. Otherwise it is incomplete.

output file

When a reservoir simulator runs, several files will be generated. These will have extensions such as .EGRID, .FEGRID, .UNSMRY, .GRID, .INIT, etc. See the opm flow manual Appendix D (https://opm-project.org/wp-content/uploads/2023/06/OPM_Flow_Reference_Manual_2023-04_Rev-0_Reduced.pdf)
