As an estimate, how many acres of land (in PA) are required to build a completed conventional gas well pad equivalent to one completed Marcellus pad with eight horizontals? You choose the numbers, though may I suggest 1,500' vertical conventional to 6,000' vertical, 6,000' horizontal Marcellus plus whatever other basic variables must be considered like gas density (?). Please include access roads if possible and let me know if you did.

This calculation may be used in my dissertation 'the impact of technology on society: fracking in the Marcellus of Pennsylvania.' I admit to being lazy about doing the calculations, but expect an engineer or two to provide me with better quality information. I have viewed both types of activities by foot in Warren, McKean, Bradford, and Washington Counties, and by satellite via GoogleEarth.
