Offshore hivis sweep formulation - old school ?

26 September 2010 In my youth there was a procedure for hi-vis sweeps using prehydrated bentonite and lignosulfonate thinner. Basic procedure was add bentonite to fresh water until VERY thick, thin back with lignosufonate, add more bentonite.

I can't find any procedures or aproximate pounds per barrel in my notes.

Anyone have a longer or better memory?
