FXEF, it is mistake as the well does not have two laterals and the well is shown in the wrong location.

I agree, this one looks like a simple mistake.

I've seen a fair number of SONRIS records with obviously wrong data like this. Apparently, when they enter in a bad bottom coordinate, they usually don't remove the bad coordinate when they enter the correct one.

You'll also see "double" well bores like this where a permit was applied for and expired, when they reapplied, they apply for a different bottom hole coordinate.

There are also a few "visual doubles" with a superpad configuration, but if you check more closely, the well surface location is actually slightly different between two different wells.

Note that SONRIS does NOT show the actual wellbore location. It shows the surface well location, the bottom hole location and draws a line between the two. Since many of the wells have slanted "verticals," the lateral may actually be significantly different from what's shown by SONRIS.

I wonder if they ever actually do drill more than one lateral from a single surface location? I guess it's possible if they have a problem with one well bore, plug it, and then "kick off" and do another well bore. Do they ever have two producing well bores from a single surface well bore?

Mac, it is not really technically feasible to do two multi-stage frac'ed laterals from the same vertical wellbore in the Haynesville Shale. Multiple horizontal laterals (6-8) have been done in the Giddings Field (Austin Chalk) but these were not mult-stage frac'ed laterals.
