A method for determining a TAN-IR for naphthenic acids in crude oil or crude oil fraction may include determining an IR spectrum of a sample of the crude oil or crude oil fraction. The method may include determining an IR spectrum of a neutralized sample of the crude oil or crude oil fraction. The method may include utilizing the IR spectra of the sample and the neutralized sample to determine a modified TAN-IR.

A method of tracking the rate of corrosion of a metal conduit traversed by a corrosive fluid, in which is provided a device arranged so as to form, when said device is installed on a wall of the metal conduit, a chamber able to receive gaseous hydrogen issuing by permeation across said wall of said conduit, the method comprising: (i) a step of treatment to eliminate a metallic species from the chamber, (ii) a step of measuring a quantity of hydrogen received in the chamber, with a view to estimating the rate of corrosion of the metal conduit.
