Introduction
The oil and gas industry experienced some significant challenges in 2020. With the sudden reduction in fuel consumption, there was a substantial global surplus of crude oil. This situation caused storage facilities to reach maximum capacity and even tanker trucks to store unwanted products.
In this context, the abandoned storage facilities are currently undergoing restoration to put them back into service; operationally, the construction of new tanks is being considered to increase capacity to higher volumes; all of which translates into expanding the number of inspections of tanks in service to evaluate the critical components in the internal and external part of the asset.
This article will provide a comprehensive review of NDT techniques that can be applied to storage tanks put back into service.

Due to the nature of MFL, it is recommended that a percentage of the detected flaws be accurately quantified by Ultrasonics (UT), typically with a UT flaw detector. With advances in technology and scanners, Phased Array Ultrasound (PAUT) fig.2 has become the technique of choice due to its superior ability to categorize and size a defect type, thus ensuring a more accurate integrity assessment.
