1. n. [Well Workover and Intervention]

The point at which the forces acting on a tubing string suspended in a live wellbore are equal. Under these conditions, the weight of the tubing string is balanced by the wellbore pressure acting to expel the string from the wellbore. The friction caused by the tubing string passing through the stripper or wellhead sealing device acts to extend the interval over which the balance point is apparent.
