Abstract:
Methods and systems for detection of pipe characteristics, such as defect detection, including corrosion inspection, of downhole tubulars and overall thickness estimation of downhole tubulars. A defect detection method may comprise disposing a defect detection tool in a wellbore, wherein the defect detection tool comprises a transmitter and a plurality of receivers; processing measurements from the defect detection tool in the wellbore to obtain a well log, wherein the well log comprises a metal loss measurement; storing the well log in a database; importing the well log from the database into inversion software; loading a well plan into the inversion software; determining collar locations on at least one concentric pipe in the wellbore utilizing a collar locator algorithm in the inversion software using the well log and well plan; calibrating a forward model in the inversion algorithm utilizing a calibration algorithm in the inversion software using well log, well plan and collar locations; generating an output log utilizing the inversion algorithm in the inversion software on the inversion zone, wherein the output log comprises metal thicknesses of at least one concentric pipe of a plurality of concentric pipes, and collar locations; and determining false metal loss in the output log using the output log, well plan and collar locations.

Claim (Index 18):
The defect detection system of  claim 17 , wherein the information handling system is further configured to generate an updated output log using the false metal loss.
