so 4 laterals will have 4 vertical bores to the surface ?
That is correct. Each well will have it's own vertical component, with a presence at the surface to allow for completion of each well individually.
It is an engineering marvel, with all the surface wellbore locations on a pad generally less than 50' apart, yet the horizontal leg of the wells will be spaced some 600-1000' apart at the target formation depth.
thanks for the info bullfrex this stuff is very interesting
