Gulf of Mexico

Formation type
Postsalt and salt
 
Application
Deepwater
 
Hole size
8 1/8 in

Background
An operator drilling in formations with stength and friction factor contrasts was enlarging a vertical borehole from 181/8 in to 21 in. Occasional BHA failure and associated NPT had been experienced, and the operator needed to improve the reliability of the BHA to drill the section to TD without incident.
