Nah.they went wrong by not having the experience of drilling these types of wells.
Their acreage at Barnhart is smack in the middle of EOG.

"EOG completed a number of wells in Irion County, Texas. The Munson #1005H, #1006H and #1007H began production at 965, 970 and 1,290 Bopd with 55, 60 and 100 Bpd of NGLs and 400, 430 and 730 Mcfd of natural gas, respectively. EOG has 85 percent working interest in these wells. The Faudree #10H, #11H and #12H were completed at 560, 670 and 810 Bopd with 50, 70 and 60 Bpd of NGLs and 365, 490 and 420 Mcfd of natural gas, respectively. EOG has 75 percent working interest in these wells. EOG has 80 percent working interest in the University 40D #0702H and #0701H, which began production at 660 and 705 Bopd with 75 and 95 Bpd of NGLs with 550 and 685 Mcfd of natural gas, respectively. "

As for acreage in Fiesta, AREX states categorically that it is a misconception that wells are gasier as their play moves southwards.
They have wells very close to Molopo's boundary.
