Abstract
Apparatus and methods for acquiring strain profiles of an optical conductor of a wireline cable in a wellbore, either while the cable is lowered and/or at intervals during the lowering when the cable is briefly stationary. Changes in the acquired strain profiles are utilized to infer or otherwise determine changes in the disposition of the cable.
