Guess what im saying, its always been, yeah, a 40k should do this shot, or a yep, 20x22 will do it. Ive never been part of the math of the pull; just the math on the geometry (I say that kinda jokingly, not real math, more of we probably need a +12% to get up by the exit; not the real math used on these river shots)

I watched one a few months ago, little JT10, 240 ft of 2", very nearly seized up; took hours (and some jerking/abuse) to get it across; and found the mud mixer to drill screen was completely clogged, with trash; so it was basically a dry (other than ground water) bore, in sand. If that is displaced to operator, wouldn't you see mud pressures at crazy levels and pull rods back?

Don’t have an answer for you on machine size. But when my trash screen gets clogs it means I get no water to pump so no pressure and no water out the head. Drilling still works(until you overheat the sonde) but steering in hard ground without water is “difficult”. lol.
