ABSTRACT:
Blends of alkyl polyglycoside surfactants having an alkyl chain length of C11 to C16 and blends of alkyl polyglycoside surfactants, in the presence of an ethoxylated alcohol cosurfactant, will form Winsor type III microemulsions in a water-oil mixture in a hydrophile-lipophile balance range of at least about 9.8 to 10.8 at 130.degree. F. wherein the water may be a chloride brine. The compositions are particularly useful in oil and gas well cleanout operations, formation acidizing, and well cementing operations and provide superior cleaning ability for removal of oil based drilling fluids, hydrocarbons and oil based pipe sealant and lubricant compositions, for example.
