REEVES COUNTY TEXAS - East on Ward County border

I have learned that I may own mineral rights in these areas of Reeves County, TX.

Section 12, Block 3, H & GN RR Co. Survey, Reeves County, Texas and part of Section 13, Block 3, H & GN RR Co. Survey, Reeves County, Texas.

I looked on the TX RR Commission site and see that there is activity on these sections. Can anyone tell me who is drilling/working there?
