Breakover Torque
Breakover (static) torque after connections can be a reliable indicator that the drill string is getting differential stuck. While drilling, connection practices should be tailored to capture the relevant data:
• Rotate FIRST after a connection (no up-down movement of the string)
• Record peak torque (i.e. breakover) values
• Compare to the dynamic off bottom torque
In this example, there was little difference between the breakover and the off bottom torque in the Claystone section. There was a significant increase in breakover torque from 13,250’ (Friction Factor>0.25) in a clean sand with permeability. On the last two connections at 14,060’ and 14,157’, the static Friction Factor = 0.33 indicating increasing differential sticking while the pipe was stationary
