I was out in the Texas Oil Fields recently training some students. We were looking for flow lines… but I didn’t even know what a flow line was until I came to Texas!

Flow lines are what carry out oil, gas, and water from the well and these can run in any direction. Or as one of the students put it, “they can come this way, go under the road, do two 360s, and leave the way it came.”

How should we go about finding these?

Step 1: find a flow line that you know the location of and image it with the GPR.

Step 2: Go look for the same response else where.

Step 3: Once you find the same response…keep tracing that response, marking along the way.

Step 4: Treat yourself to some quality Barbacoa for a job well done.

This isn’t only for mapping flow lines, or even pipes and utilities in general. I use this technique all the time when working in historic cemeteries. Graves will have different levels of amplitude based on decay and soils. Imaging marked graves is a great way to begin, before ever going after unmarked graves.

If you use GPR and didn’t know how this worked, then you should get further training. Check out our upcoming webinars, classes, and live workshops at LearnGPR.com.
