SFG™ is designed for use in cement spacer systems to water-wet the formation and pipe surfaces, removing the excess hydrocarbon film left behind from non-aqueous drilling fluids. In this way, SFG aids cement bonding and zonal isolation to improve the integrity of the cement job.
SFG can be used in both weighted and unweighted spacer systems, and provides excellent cleaning efficiency at low concentrations. When used properly, this surfactant improves the effectiveness of the spacer system while displacing non-aqueous drilling fluid. Laboratory testing is recommended to determine optimal concentration.
