Abstract: A method comprises determining a value of at least one oppositional force for a drillstring at multiple depths in the wellbore, determining a value of a drag force for the drillstring at the multiple depths, determining a value of hook load for the drillstring at the multiple depths based on the value of the at least one opposition force and the value of the drag force at the multiple depths, and determining a calibrated drillstring weight based on a change in the value of the hook load over the multiple depths. From the calibrated drillstring weight, an adjusted estimated hook load can be determined. The drag force can be calculated based on a drag per centralizer and the number of centralizers in the wellbore. A centralizer friction factor can be determined and used to calibrate the value of the drag per centralizer.

Systems and methods for regulating WOB may monitor and change the rate of penetration (ROP) or may maintain the ROP within a target range therefor. The methods for regulating WOB may include characterizing an average force profile, determining whether force profile disturbances occur at similar well elevator position, receiving data stream of hook load and elevator positions, and applying a force correction to the hook load during tool joint passing events. Systems and methods for regulating WOB may receive force profile data and sensor measurements including WOB, torque, and differential pressure for a current position of the tool joint and provide an adjustment to the ROP or maintain an ROP when the tooljoint passes through the rotating head.
