Abstract

In order to determine the extent of offield tubular corrosion, often multiple corrosion detection methods are required. These include measurements of magnetic properties in casing, determination of induced or naturally occurring electrical current flow, and electrical determination of casing wall thickness. The technique described is a framework to integrate these measurements maximizing the use of color imaging of the data. This approach facilitates quantitative evaluation of the tubular condition as well as enabling a macroscopic view, to better assess corrosion mechanisms.
