Claim Text:
1. A method for monitoring a downhole tubular defining a tubular axis comprising: transmitting one or more light signals into one or more optical fibers coupled to the downhole tubular at one or more attachment points, the one or more optical fibers extending substantially linearly along the downhole tubular; detecting and processing, through a central processor, the one or more light signals to form a data set; determine an induced torsional value of the one or more optical fibers at one of the one or more attachment points; comparing, through the central processor, the data set with predetermined location data describing the one or more attachment points to estimate one or more error values associated with the induced torsional value of the one or more optical fibers at the one of the one or more attachment points; and combining the data set and the one or more error values to determine one or more selected parameters of the downhole tubular.
