Maximum Torque for 13.3/8" Buttress

26 April 2006 Maximum Torque for 13.3/8" Buttress

Planning to drill with 13.3/8" casing. What is the maximum torque
that can be applied to a Buttress connection on 13.3/8" 68 ppf L80
casing (without torque rings)? The risk is casing connection
failure. The API make-up torque for the Buttress connection is
13,380 ft.lbs, but it is likely we will exceed this when drilling
with casing. I cannot find yield torque data for Buttress connection
in public domain.
What is other Operators\'experience (actual, empirical or opinion).
