I'm sure someone has the expertise to address this, but I imagine that deeper wells take significantly longer to set up and drill than shallower wells. As such, as you go deeper, you would need more rigs drilling just to maintain the same rate (wells/year) of drilling that would be done in shallower locations. In this way, it seems the problem of number of rigs available would get further magnified.

Any thoughts?

 Your assumption is correct. A well of greater depth will typically require additional rig time to reach TD. The rig will also need to be of greater HP to handle the associated loads. Horizontal wells will also typically require greater HP. I include the caveat of "typically" as much depends on the type of formations being penetrated but you are correct that these factors will serve to reduce the EROEI.
