Mesophase fluids with extended chain surfactants for downhole treatments

摘要: Mesophase fluids may be pre-formed or formed in situ and used downhole for various treatments including, but not limited to, cleaning up removing non-polar materials from reservoir production zones, wellbore damage, releasing stuck pipe, components spacers pills the like oil gas wells. These involve solubilization of material into emulsion when treatment fluid contacts materials. mesophase use extended chain surfactants having propoxylated/ethoxylated spacer arms. The are intramolecular mixtures containing hydrophilic lipophilic portions. They attain high (e.g. single phase microemulsions), some instances insensitive to temperature useful a wide variety types.
