Abstract
Methods and devices for testing friction reduction systems are described herein. Embodiments of the disclosed devices allow direct measurement of fluid or rheological properties of friction reduction systems in a “one pot” or integrated device while maintaining the particles in suspension. In an embodiment, a device for testing a friction reduction system comprises an outer chamber. The device also comprises an impeller disposed at the bottom of the outer chamber for mixing the friction reduction system. In addition, the device comprises an inner chamber fixedly disposed within the outer chamber. The inner chamber has an inlet and an outlet such that the inner chamber is in fluid communication with the outer chamber. The device further comprises a bob rotatably disposed within the inner chamber.
