Surfactant for Hydrochloric Acid Matrix Stimulation HCl Emulsified Acid (SXE) Surface Tention and Interfacial Tention Reduction

Surfactant Additives is generally used in stimulation fluids to reduce interfacial tension that restricts the flow in matrix rock. Compared to other surface active agents, Surfactant Additives lowers both surface tension and interfacial tension dramatically. The capillary pressure for stimulation fluids containing is therefore reduced to facilitate cleanup and fluid recovery.

Surfactant Additives is an effective surface active agent used in facilitating fluid flow and fluid recovery in most acidizing and fracturing operations.
Surfactant 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, Surfactant Additives 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.
Surfactant Additives is compatible with most additives in stimulation fluid systems. It is also biodegradable and presents lower toxicity to organisms than other surface active agents.
