Breakout Position

What Does Breakout Position Mean?

The breakout position is defined as the final location of the drill string and breakout wrench for the unscrewing of the drill string components. The final breakout position is ultimately determined by the next planned operation after the drilling process has stopped (for example, disconnecting a steerable pilot bit to replace with a back reamer at the exit point of a horizontal bore).


Trenchlesspedia Explains Breakout Position

Break out is the processing and disassembling of the various drill string components including tool joints and threaded connections.

After setting the drill string in the breakout position, heavy duty, self-locking wrenches, called breakout wrenches, are also moved into the breakout position to grip the drill string. A torque is then applied and the various components are unscrewed.

Often, a similar set of opposing wrenches is tied off to a deadline anchor to provide an opposing backup force.
