A Winning Solution
In Brazil, an IOC required around 30-40 joints of 14’’ casing for the bottom of the string inside a salt dome, which presented a higher risk of collapse. Ordering new pipes would take too long, so the IOC ordered a visual inspection and ultrasound examination using the In-Pipe Rover on 14’’ stocks in their yard.
Of the 50 inspected pipes, 36 were accepted with full-length wall thickness greater than 90% of nominal value. The operator was able to categorize pipes according to wall thickness and ensure well integrity in the salt dome.
