New wells are horizontals so while the wellsite might be on adjacent section, the productive wellbore will cross into your section. So you need to look for permits. Your legal description does not include the Range, so cannot see current activity. Keep in mind that (1) offers are frequently generated when buyers see new permits or hear about well plans or see good new wells nearby; (2) buyer is not bound to stated price and (3) it is not a good deal for you to be paid on a multiple of current revenue if new wells are going in.
