Unfortunatelly I dont know anything about corrosion minitoring in crude oil pipelines. I have some expirience in natural gas pipelines where there is a cathothic protection with dc power that is monitored remotely with testing points in every section.
When current increases they can cut the sections and find by local measurements the leakage to the ground.

Sorry that i cant give any more help.
