The customer was sidetracking the well, and unable to run their 16-inch liner. The 13-5/8 inch and 11-3/4 inch casing were both set high, which would compromise the originally planned 8-1/2 inch hole size.

 

The operator selected a 9-5/8 x 11-3/4 in. SET®...

An operator drilling a sub-salt exploration deepwater well in Gulf of Mexico, experienced an unstable wellbore at the base of the salt; which resulted in setting the 9-7/8 in. liner 3,400 ft higher than originally planned.
In exploratory wells, maintaining hole size is critical due...
