1. A method for assessment of a tubular, said method comprising:
utilizing a material features acquisition system operable to detect a plurality of material features in said tubular, said material features acquisition system comprising a sensor;
providing a database to retain data so that said material features acquisition system is operable to produce a history of said tubular whereby said material features acquisition system is operable to detect and monitor changes in said tubular from repeatedly scanning said tubular with said material features acquisition system over time and wherein scanning said tubular comprises providing axial movement between said sensor and said tubular;
providing that said material features acquisition system is responsive to a material feature for calibrating said material features acquisition system from a calibration sample;
detecting an output of said sensor;
calibrating said sensor with a calibration sample comprising a plurality of different material features;
providing that said material features acquisition system is operable to evaluate said output of said sensor to detect new material features and monitor previously detected material features in said tubular from said database; and
providing that said material features acquisition system is operable for determining a degradation mechanism from a plurality of possible degradation mechanisms or changes affecting said tubular.
