- The high temperature viscosities of selected oil formulations were determined over a broad range of shear rates using refined techniques of applied rotational viscometry. The high shear rate measurements (1×105 to 2×106 sec−1) were made with a Tapered Bearing Simulator (TBS) viscometer fitted with a precisely balanced rotor; the low shear rate measurements were made using a newly designed SavanTech test cell coupled to a Brookfield viscometer modified for this application. Unique graphical profiles were generated depicting the viscometric performance of currently used polymeric thickeners.
