#17 SUU and #18 California each have two meets remaining before Regionals but I don't think either can get to the top-12 without out out-of this world scores ... they'd have to have both scores well above their current season high.

Given the above caveat ...

OSU will be no lower than a #12 Seed for Regionals.

With a score of 197.400 or higher at Pac-12s, OSU can be ranked no lower than 8th (passing #7 Denver & #8 Georgia, but still could be passed by Michigan ... even with a season high).

With a score of 197.325 or higher at Pac-12s, OSU can be ranked no lower than 9th (passing #7 Denver, but #8 Georgia could stay ahead)

With a score of 197.025 or higher at Pac-12s, OSU can be ranked no lower than 10th (staying ahead of #11 Boise State & #12 Kentucky)

With a score of 196.925 or higher at Pac-12s, OSU can be ranked no lower than 11th (staying ahead of #12 Kentucky)

A score of 196.900 could result in a tie for 12th ... below that score OSU could be ranked 12th ... #13 Kentucky can only get to an RQS 0.010 below OSU's current RQS ... so theoretically they could pass Boise State and Kentucky, but not pass OSU.
