Abstract

A method of forming a wellbore with a drill string and that includes continuously and automatically measuring a TARE value of the drill string. The TARE value of the drill string is measured while the drill string is rotating, fluid is circulating in the drill string, and after the drill string has been axially stationary for a set period of time. The TARE value is designated as an average of the measured hook load over the latter half of the set period of time. Knowing the measured TARE value and a designated weight on bit ('WOB') of the drill string, a hook load for supporting the drill string is calculated. Matching the force applied that supports the drill string to the calculated hook load results in an actual WOB that matches the designated WOB.
