I take it all back. Not only did ya'll provide some interesting feedback, but I went back and checked leases again. On 11/16/17 Jeter sold/conveyed 48 leases to something called National Landworks, who in turn assigned the leases to EOG.
These leases amount to around 4500 acres and run generally from where 957 turns north into Fayette County, north to about where the Wolters well is/was, NE to about the intersection of Billimek Road and FM 1579 (old Hwy 90), then south to the SE corner of Fayette County. Obviously there's a lot more acreage within the area I just described, so this is patchwork to say the least. In addition, I'm too lazy to see how much of this is contiguous and big enough to actually make a unit at this time, but it's of interest regardless.
<Update> I just went into Lavaca County filings and see that the same thing happened on the same day there.
