SDGA-700 SELF DIVERTING GELLING AGENT

DESCRIPTION

SDGA-700 is a non-polymeric blend of cationic surfactants used to produce self-diverting acid systems and can be used as a foaming agent. Viscous acid penetrates deeper into the formation before spending. As pH rises, the viscosity breaks; however, there is enough residual viscosity to flow back acid-insoluble fines. Viscosity of 50-60 cps is typical for acid used up to 155 deg F

APPLICATION

SDGA-700 can be added continuously while pumping or it can be premixed before pumping. if premixed, agitate thoroughly to insure proper mixing. SDGA-700 increases viscosity in HCL acid (up to 20% in concentration). When used in higher concentration acid the gel does not form until the acid spends below 20%. Use 2 to 4% or20-40 Gallons / M gallon SDGA-700. It is compatible with both cationic and nonionic Surfactants. Do not used with anionic surfactant, such as anionic anti sludge agent
