Bill,
When you directional drill in the pin wheel style grid, after you pullback the product, don't you have to pump bentonite into the bare hole? or just pump bentontie the entire application? also if you use a 4.5" bit why is there a need for a reamer? is the product over 2.5 dia??? Reason I ask is I'd really like to start drilling some geo,,, in between my fiber jobs.
Also it would seem to me that each job would have variables as in which method would best suit the lot. Probably need a long lot to do the directional and then why would you ever want directional if vertical is an option... Can't vertical be used in almost every application???
