ABSTRACT:
Provided is a method of reducing the torque required to rotate the drill string in a rotary well drilling process which comprises adding to the drilling fluid which is being circulated in the wellbore a liquid organic lubricant and a hydrophobic, organophilic, water wettable sorbent. The sorbent preferentially sorbs the lubricant and deposits it in the wall cake on the sides of the borehole thus making it available for lubricating the drill string.
