Abstract
Colloid and/or micelle nano-sizing compositions including a nano-sizing solvent system comprising one or more sesquiterpene solvents, and a nano-sizing activator system comprising one or more dibasic esters, surfactant systems containing colloid and/or micelle nano-sizing compositions, treating/fracturing/completion fluids containing the colloid and/or micelle nano-sizing compositions and methods for making and using same.
Claims20
A surfactant composition comprising:
- (a) a mixture of one or more nonionic surfactants and one or more anionic surfactants or (b) a mixture of one or more nonionic surfactants and one or more cationic surfactants, and a colloid and/or micelle size reducing composition comprising:
- a solvent system comprising one or more sesquiterpenes, and
- an activator system comprising one or more dibasic esters,
- wherein the colloid and/or micelle size reducing composition reduces a size of colloids or micelles to less than or equal to 100 nm when added to a downhole fluid.

A downhole fluid composition comprising:
- a base fluid, and
- a surfactant composition comprising:
- (a) a mixture of one or more nonionic surfactants and one or more anionic surfactants or (b) a mixture of one or more nonionic surfactants and one or more cationic surfactants;
- and
- a colloid and/or micelle size reducing composition comprising:
- a solvent system comprising one or more sesquiterpenes, and
- an activator system comprising one or more dibasic esters,
- wherein the colloid and/or micelle size reducing composition reduces a size of colloids or micelles to a size of less than or equal to 100 nm in the downhole fluid composition.
