Summary: | A tangible, non-transitory, machine-readable medium, includes machine-readable instructions to obtain a measurement relating to a first metal thickness of a casing by passing a transmitter and a receiver of an electromagnetic logging tool over a defect. The tangible, non-transitory, machine-readable medium, also includes machine-readable instructions to obtain a ghosting kernel of the electromagnetic logging tool including a response of the electromagnetic logging tool to a localized change in metal thickness from the first metal thickness of the casing to a second metal thickness, wherein the second thickness is different from the first metal thickness. The tangible, non-transitory, machine-readable medium, further includes machine-readable instructions to determine the metal thickness of the casing at the defect based on the measurement and the ghosting kernel of the electromagnetic logging tool. |
