I noticed that you and someone else with the name Connally are included in the Pembrook Unit in NE Upton County. That is a huge Unit containing over 42K acres and with 325 or so Wells in it.
Sec 8, Blk N is part of the Pembrook Unit. I hope they aren't trying to steal your interests in the entire pooled 42K+ acres, because it appears that Pioneer is drilling Horizontal Wells in it (See the information on the Pembrook Unit No. 905H attached).
Aside from that, I was able to find that three Horizontal Wells were completed last Spring by Pioneer that include Section 8, Blk N in their 1,118.7 acre Lease: The Brook M-1A No. 1H, the Brook M-1B No. 2H and the Brook M-1C No. 3H.
Note that these three Wells are not Pembrook Unit Wells. I have attached some preliminary information for you on them and have a fairly comprehensive set of information on them if you would like that but I could only attach so much to a single message.
It appears that these three Brook Wells first produced in March 2016 and that through August 2016 have produced a cumulative 359,619 Barrels of Oil and 1,101,226 MCF of Gas.
I wasn't able to determine what they are getting for the Gas, but between May and July 2016, they averaged $42.361 per barrel, which calculates out to roughly $15,233,820.46 total gross over the past 9 months. The three are averaging a combined 1,667 BOPD and 1,904 MCFD today.
I don't know your interest amount or the specific lands they are in, but like I mentioned earlier, they may be trying to buy your interests using your own money.
In simplest terms: Don't Sell. If you haven't received any royalties from these three Brook Wells yet, you may have a sizable first check coming.
Hope this helps -
