Too regularly spaced to be impact craters. With the many, there's no way you could get them to all hit that regularly.
Gotta be man-made, I should think.

After learning that this region is rich with minerals and seeing that there are many of these 'hole chains' all over this area, my wild guess is exploratory drilling.
