As I said, it is only a rumor at this point, but the rumor came from a Directional Driller & they normally know what is going on because you can't do a whole lot without a mud-motor or RSS these days, it just isn't cool... So if they were to drill deeper, the Directional Drillers would be the first to know...
From a 2nd Source: Based on findings from the Cosmo Well, the AOGCC is really excited about what might be deeper below the present TD of the Cosmo Well. They are encouraging other operators change their drilling programs, using larger diameter casing, to leave the option for deeper exploration into Jurassic Sediments...
Everything said above is a rumor... it is all a rumor...
But, In my defense, the last rumor I posted came out a day prior to a Buccaneer PR & was almost word-for-word...
