Jetting with PDC bit

We are planning to jet 36" conductor and drill 17.1/2" hole immediately below. Riserless interval 1300m through Tertiary deepwater shales, nudging into Cretaceous age formation at section TD.  Offsets used milled tooth but riserless interval was shorter. Some evidence of firming up but not entirely clear.

Any experience using PDC for jetted interval and riderless section in similar deepwater setting? Reactive torque possibly an issue? 

Thanks

Note from moderator (21st May): Please can we keep focus on the point of the queston, which was about jetting conductor using a PDC bit.
