Use of GPR (Ground Penetrating Radar) for buried pipe mapping in O & G Plant
Use of GPR (Ground Penetrating Radar) for buried pipe mapping in O & G Plant
(OP)
Dear All,
We have a project related to installation of CP system for a very prestigious Oil & Gas client for its live gas plant. Our company is taking care for the civil part which is mostly related to excavation works, reinstatement after installation of CP anodes, augering for various depths, small RCC foundations and all sorts of civil works to support the CP installation works. As per the strict guidelines of plant management, we can only dig up to 0.9m without any approvals or detailed surveys. For augering to depths more than 0.9m we need to do a subsurface scanning using ground penetrating radar "GPR" and then after making a map of existing facilities then we can proceed with excavation / augering. I want to know details about GPR and how it is used and what are the precautions related to it? Moreover is this latest technology or are there better technologies available? Need detailed insight on this topic as I have to prepare the detailed technical & commercial bid.
Any help / guidance is much appreciated.
Best Regards,
Syed Meesam Ali

I would suggest doing a physical correlation with the subsurface indications for one or two areas before you rely too heavily on the results.

But if you are looking for buried pipes 6" and up, space apart, GPR is a good choice.

It works best on flat prepared surfaces where you can make lots of lines back and forward to cover the area of interest.
Even then, once you've dug to you 0.9 m depth, I would suggest you Cat scan the bottom of the hole to pick up any small cables or pipes which may have been missed by the GPR.
You need to hire the operator as well as the machine to interpret the screens correctly.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
