Abstract:
An illustrative method for estimating casing wear, including estimating, as a function of position along a casing string, a side force of a tubular string against the casing string, wherein said estimating accounts for a bending stiffness of the tubular string. The method further including determining, based at least in part on the side force, a casing string wear volume as a function of position along the casing string, and presenting the casing string wear volume to a user.
