    At 40-50M stage spacing this is pretty well 'full-out', perhaps more like 80% of max possible. Gas shales don't require the density that liquids rich wells do, however, more holes, sand and water are always good.

    Regarding time per stage, the norm is in the 10-20m3/m of wellbore. So, 50m stages will have 500-1000m3 of water. The sand does add to volume, but is somewhat negligible for this discussion. The frac gear will pump around 10-14 m3/min. This provides a range of roughly 40-100 mins, call it 75 mins to actually pump the stage. You can probably double that time for the prep phases of perforating (making holes in casing) and pumping plugs. Loosely, call it four hours per stage. This is one reason why fracking multiple wells makes sense, you prep one while pumping the other.

    Its likely that the overlapping segments of the wells to be 'zippered', or fracked in a back and forth fashion.

    Back to the frac intensity, given the short first well, they will have more sand and water than the planned volumes per stage. Given the incremental cost at this point (sand and water already there) I am going to guess they use it and push intensities up.

    What is more interesting is the fluid rate, higher fluid rates can produce greater height and frack complexity. High rates have largely fallen out of favor due to cost, however I seem to recall somewhere reading this frack spread was large and in the order or 16-20 pumpers. They won't use all the pumpers, but if my recollection is right there is the capacity to do tightly spaced, high volume and high rate stages.

    This would be positive for the value proposition.
