Abstract
A system and method for verifying support hanger orientation within a wellhead housing. In an example, a profile is included at a designated location on an inner surface of the wellhead housing. When the support hanger is landed in the wellhead housing, an impression is taken of the inner surface of the wellhead housing from a reference location. Analyzing the impression can indicate the position of the support hanger within the wellhead housing. A running tool that can land the support hanger within the wellhead housing can be equipped with an impression block for taking the impression of the profile in the wellhead housing.
