Ground peanut hulls in the range of -150 to 250 standard size mesh are mixed with a viscosifier and added to a fluid for circulation in a borehole during drilling, completion and workover operations. Below 250 standard sieve mesh the ground peanut hulls are distributed in a range down to 700 standard sieve mesh, with some of the ground peanut hulls having a size less than 700 standard sieve mesh.
