Spudding offshore riserless with a mud motor ?

Another bone of contention that I would be interested to gather others ‘Evidence based points of view‘. 

Would be. 

Sharing EVIDENT pros and cons to spudding, ie  drilling and cement an offshore well’s conductor and surface string where subsurface conditions cannot afford jetting a conductor.  

Northern Southern Hemisphere areas, other regions where non-jettable   ) hard ground, sand carbonate dominant etc) subsurface conditions may exist. 

What is optimal ?
MOTOR vs Rotary assembly.?  
Why is this evidently so? 
What does your wells data show/state experience prove ? 
Evident Case study wells examples to share? 

What set up, has repeatedly and more consistently delivered best process safety, optimal,  higher quality, less problematical drilling  solutions. 
Why was this evidently so? 

Looking forward to members sharing evident views on this highly debatable subject, 

Note: Ask the big three service companies? they will always try and sell and tell that a motor solution is best? . 

Despite the Substance and evidence warranted?  to be checked and assessed to back this up.
