Abstract
A stop collar assembly includes a collar having inner and outer surfaces. The inner surface includes a taper. The outer surface includes a slope such that an outer diameter at a start of the slope is greater than an outer diameter at an end of the slope. The stop collar assembly further includes a slip having a bottom end and a taper adjoining the bottom end. The slip taper is configured to contact the collar taper. When the collar taper is in contact with the slip taper, a distance from a central radial axis of the collar to the start of the slope is less than a distance from the central radial axis to the slip bottom end, and the distance from the central radial axis to the slip bottom end is less than a distance from the central radial axis to the end of the slope.
