DosSurf™ AG-25 Surfactant

High Cleaning Efficiency for Drilling Mud

DosSurf™ AG-25 Surfactant

DosSurf ™ AG-25 is based on anionic and non-ionic surfactants. The surfactant package DosSurf™ AG-25 is required for the design of spacer fluids after Non-Aqueous Fluids (NAFs) have been used for drilling.

The spacer fluid, designed with DosSurf™ AG-25 is able to chemically wash NAFs away from the borehole wall by changing the wettability of the residual NAF. The cement bonding will be excellent on the formation and pipeline.
