Described is a slickwater fracturing fluid containing base water having up to 300,000 ppm total dissolved solids; a viscosifier; a scale inhibitor; and a surfactant composition. The surfactant composition contains at least one dibasic ester, at least one non-ionic surfactant, at least one terpene or terpene derivative and optionally at least one polyalkylene glycol.

Slickwater fracturing fluid

An improved method and fracturing fluid for hydraulic fracturing of a subterranean formation, the fracturing fluid including a surfactant, a water soluble or dispersible anionic organic salt, an acid and a low molecular weight organic solvent.

Fracturing fluid containing amphoteric glycinate surfactant

An improved method and fracturing fluid for hydraulic fracturing of a subterranean formation, the fracturing fluid comprising a surfactant, a water soluble or dispersible anionic organic salt, an acid and a low molecular weight organic solvent.

Fracturing method using aqueous or acid based fluids

There is described a fracturing fluid comprising a polar base, 0.1-5.0% of a mid-molecular weight polyacrylate, and an activator for ionizing the polyacrylate to a hydroscopic state.

Fracturing fluid

A method for fracturing subterranean formations surrounding oil and gas wells using a fracturing fluid consisting of a foam constituted by a liquid phase and a gaseous phase. The liquid phase has a foam forming substance dissolved therein. The foam forming substance is preferably a surfactant such as a non-ionic hydrofluoroether surfactant. The liquid phase is preferably CO and the gaseous phase N .

Foamed nitrogen in liquid CO2 for fracturing

A fracturing fluid composition for use in fracturing underground formations, such as oil or gas wells is described. It includes at least one anhydrous aliphatic alcohol, a modified guar gum polymer, and as a complexor, a sodium borate salt. A gel breaker which acts over a time period to degrade the guar gum cross linked polymer and thereby reduce the viscosity of the gel is provided as well to aid in the removal thereof from an oil or gas well that has been fractured by application of the fluid under pressure.
