Techniques for testing a wellbore tubular system include positioning a primary wellbore tubular that includes an inner volume on at least one fixed mount positioned to support the primary wellbore tubular; positioning a secondary wellbore tubular concentrically or eccentrically within at least a portion of the inner volume of the primary wellbore tubular; coupling the secondary wellbore tubular on an adjustable stand positioned to support the secondary wellbore tubular; running a logging tool within an inner volume of the secondary wellbore tubular; detecting at least one defect of at least one of the primary wellbore tubular or the secondary wellbore tubular; and moving the secondary wellbore tubular within the inner volume of the primary wellbore tubular on a roller of the at least one adjustable stand.
