I'm starting to believe these tanks are 1500-5000 gallon, above ground vertical-type, crude oil 'field' storage tanks...
Which would put each tank at about 4'-8' in diameter and anywhere from 8'-16' tall (per API spec).
Here are examples of some in Texas:
As another poster touched on earlier, what we're seeing are buckets under the drain lines, of the tanks.
Putting the 'tire marks' to scale, as dually/tandem axle marks, not overall vehicle width-tire tracks, like we had originally put to thought.
Meaning that the lights we're seeing very well could be from a single or double axle standard duty trailer-sized object, and that the 'object'
we're seeing isn't as gargantuan as we had previously mentioned. My guess is that it's a pull-behind trailer.
Also, I've found a few 'suspect' drill/storage sites that the OP's image could be from, in Cotulla, Texas...
