Cleaning Test

For cleaning test, a pre-weighted rheometer sanded sleeve is coated with test mud. The sleeve is then placed in the DosSurf™ 10 Surfactant solution. The appearance and weight of the sleeve are recorded during the test and the percentage removal is calculated. It is recommended to use in spacer formulation to remove oil based drilling fluids. This product used with fresh water, sea water and various brines including NaCl and CaCl2.
