ABSTRACT:
A drill-string member includes at least one grooved portion on an outer surface thereof. A pair of axially spaced-apart grooved portions are typically provided, with two such pairs axially spaced along the longitudinal length of the member. A plurality of grooves are milled into the grooved portions, and the grooves intersect with one another to form a criss-cross pattern. As the member is rotated, fluid flows up the grooves, where fluid from one groove meets fluid from another groove at each intersection, causing turbulence to be created.
