G12mo has always had doubts, trouble is that Senex keeps ticking all the boxes he is going to run out of things to doubt.
Seriously though have a look at the detailed maps Senex put out in the latest quarterly or Reserves statement for Atlas, have a look at how many wells have been drilled hard up against the Atlas border and tell me it is not in a good spot and is not extremley derisked - particularly the north/western half.
The (south) eastern side may not be as sweet as it is not derisked and as such they haven't booked reserves accordingly.
