Abstract
A method for determining a depth related parameter of an instrument in a wellbore includes measuring movement of the instrument along the wellbore using a wheel sensor urged into contact with a wall of the wellbore. Movement of an instrument conveyance is measured proximate the surface. Measurements from the wheel sensor are calibrated using measurements of movement of the instrument conveyance. The depth related parameter of the instrument is determined using the calibrated wheel sensor measurements.
