Hi Chaojie,
Thanks for reaching out for clarification.
As I read your question, this should be fine. For reference (since I know old e-mails get buried), we clarified a similar questions in an e-mail to all participants in January:
Considering that the SPE11 data is publicly available, we welcome its utilization in current research even before the conclusion of the CSP cycle at the end of 2024. Nevertheless, we would appreciate if direct comparisons among simulators based on SPE11 data are not made public at this time, since this would compete with the Comparative Study Project itself. With this in mind, we encourage authors who utilize the SPE11 data to consider submitting their work to the special issue of SPE Journal and/or to the 2025 SPE RSC.
Of course, if you choose to use the SPE11 dataset, the appropriate reference is the final version published in SPE Journal:
Nordbotten, Jan M., Fernø, Martin A., Flemisch, Bernd, Kovscek, Anthony R., and Knut-Andreas Lie. "The 11th Society of Petroleum Engineers Comparative Solution Project: Problem Definition." SPE J. 29 (2024): 2507–2524. doi: https://doi.org/10.2118/218015-PA
Best regards,
Jan
