Viscoelastic Surfactant

A new foam fracturing fluid composed of sodium dodecyl sulfate (SDS), fluorocarbon surfactant (FCS-11), viscoelastic surfactant VES is proposed and developed in this paper. The performances of this fracturing fluid were systematically investigated. The experimental results show that this foam fracturing fluid has good shearing resistance, viscoelasticity and stability. And above all, once broken it has no residue and the damage rate is only 10.12%. These advantages give it a wide application prospect in coal bed methane development.

The solubility of chlorophenols as affected by surfactant was investigated. Three kinds of surfactant, sodium dodecyl sulfate, Triton X-100, and Brij 35, were utilized. The solubilization of chlorophenols by surfactant follows the order of 2,4,6-trichlorophenol > 2,4-dichlorophenol > 2,6-dichlorophenol > 2-chlorophenol; and the critical micelle concentration is an important index. The adsorption reactions of 2,4-dichlorophenol and 2,4,6- trichlorophenol onto hydrous montmorillonite in the presence of surfactant were examined. The presence of surfactant decreased the adsorption of chlorophenols significantly. The roles of hydrophobicity of chlorophenols in solubilization and adsorption behaviors are discussed.

Different submicellar solubilization mechanisms of two systems, Triton X-100/tetradecane and sodium dodecyl sulfate (SDS)/butyl methacrylate, are revealed on the molecular scale by 1H NMR spectroscopy and 2D diffusion ordered spectroscopy (DOSY).
