This is the OPM repository which is supposed to contain all relevant datasets and simulation results which are required to test the OPM simulators thoroughly.
Unless stated otherwise, decks are now provided under the open database license available in the file odbl-10.txt, and new decks should also be provided under the same or a compatible license. Similarly, data contained in or pointed to by the decks is licensed under the open database content license available in the file dbcl-10.txt.
Note that the git history contains proprietary decks (now removed) where usage restrictions may apply.
