Abstract:
An open-loop drilling fluid homogenizer for use in a closed-loop designed drilling fluid system comprising:(a) a fluid inlet adapted to receive a water-based drilling fluid; (b) an expanded tubular pipe portion coupled to said fluid inlet; (c) homogenizing means housed in said expanded tubular pipe portion, for homogenizing, under pressure, in an open-loop process said water-based drilling fluid having suspended therein globs of undissolved polymer granules for creating a non-clogging homogenized water-based drilling fluid having substantially all glob sizes of said globs of undissolved polymer granules less than or equal to a predetermined non-clogging glob size; and, (d) a fluid outlet coupled to said expanded tubular pipe portion adapted to output said non-clogging homogenized water-based drilling fluid.
