Increased permit activity in Sec 3-15, 40 T3S

I am seeing a lot of new permits for horizontal wells in Sections 3-15 of Blk 40 T3S. Does anyone have any insight into why there is increased activity? Apache has had some successful Braun wells and Endeavor has some big Rio Llano wells in Sec 10-11. I presume this is the reason but is there anything else driving it? I can’t recall so much activity in such a tight space.
