A hydraulic fracturing fluid and methods for using the hydraulic fracturing fluid fracturing a formation are provided. An exemplary hydraulic fracturing fluid includes a polymer additive, a breaker, a non-ionic surfactant. The hydraulic fracturing fluid also includes an amphoteric surfactant, or a cationic surfactant, or both, and a base fluid.

Low surface tension surfactant system for enhancing flow-back performance

A composition includes an ionic liquid monomer having the following structure: where n is an integer from 1 to 5 and the ionic liquid monomer has a melting point less than 100&#xb0; C. A method of making the ionic liquid includes providing a mixture comprising a sulfonic acid and a diamine in a solvent, and maintaining the mixture at a temperature ranging from 10 to 80&#xb0; C. for a time ranging from 1 to 10 hours to form an ionic liquid monomer having a melting point less than 100&#xb0; C. A method of making a polymer from the ionic liquid monomer is also provided.

Ionic liquid monomer for synthesis of friction reducer and methods thereof

Provided is a composition that may include a mixture of an ionic liquid and a surfactant in an aqueous composition, where a carbonaceous hydrocarbon-bearing formation has a wettability value and comprises hydrocarbons, where there is an interfacial tension value between the aqueous composition and hydrocarbons present in the carbonaceous hydrocarbon-bearing formation, where the aqueous solution may be configured to modify the wettability value of the carbonaceous hydrocarbon-bearing formation from a first value to a second value that is more water-wet than the first value, and where the presence of the ionic liquid in the aqueous composition may not substantially impact the value for interfacial tension between the hydrocarbons in the carbonaceous hydrocarbon-bearing formation and the aqueous composition. Further provided is a method that may introduce the aqueous composition into a carbonaceous hydrocarbon-bearing formation.
