Membourne_(Roger Mills Co, OK) Beaverdam Well

I’ve been contacted by Membourne regarding Minerals under well name of Beaverdam 13/16 OO Fee Com 1 H, a multi_unit horizontal well in the Cherokee formation total depth of 28,680’.

Question: Does the Cherokee formation even exist at that depth.?

Thanks for any input.

That depth is a measured depth for the lengths of the horizontal well, so along the borehole and not all the way straight down.
