SL-K1212 is composed of a variety of active agents, which have the characteristics of non-ionic surfactant, low surface tension, good thermal stability, good compatibility and easy to use. The adsorption capacity on the formation rock is very low, which can keep the hydrophilicity of the formation rock unchanged.
Flowback Surfactant
Flowback Surfactant SL-K1212
SL-K1212 is mainly used in oil and gas well fracturing, acidizing and other downhole operations, to reduce the surface tension /interfacial tension, so that the residual fluid back faster and more thorough, effectively reduce formation damage.

Product Description
Technical & Engineering Information
SL-K1212 is unique in chemical nature so that it not only reduces surface tension and interfacial tension of the stimulation fluids, but also changes wettability behavior of the fluids in rock matrix. The capillary pressure that is required to initiate fluid flow is greatly reduced. Therefore, SL-K1212 can provide quicker and better fluid recovery following acidizing and fracturing stimulation treatment. It leaves both sandstone and carbonate formations water wet for more effective stimulation treatment.
SL-K1212 is compatible with most additives in stimulation fluid systems. It is also biodegradable and presents lower toxicity to organisms than other surface-active agents.
