Abstract: A well stimulation method based on a self-dispersible and non-surface functionalized dispersion fluid to recover hydrocarbons from subterranean formation in conventional and non-conventional mode is described and claimed. The method includes introducing a self-dispersible, non-functionalized, three-dimensional (3D) crumpled graphene balls/structures into a water slug, a gas slug, a liquefied gas slug, a natural gas liquid slug, or a diesel slug.

The said self-dispersion fluid may also contain a cocktail based on varying degree of hydrophilicity and hydrophobicity of 3D crumpled graphene balls, where the role of 3D hydrophilic crumpled graphene balls is to keep dispersion stable whereas, the role of hydrophobic 3D crumpled graphene balls is to interact with hydrocarbons and thus stimulating their dislodging or desorption from the rocks of subterranean hydrocarbon formation.

Abstract: Compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean oil formations. Concentrates include a sulfonated and/or a sulfated surfactant, an alkoxylated alcohol surfactant, a coupling agent, a hydrotrope, an additional surfactant, and water. Injectate compositions for oil recovery include the concentrate and a water source such as a produced water and/or seawater. Inclusion of particular hydrotropes such as sodium xylene sulfonate and/or potassium toluene phosphate in the compositions provides higher yields of hydrocarbons recovered. Larger amounts of hydrotrope result in an increase in injectate interfacial tension, but also result, as judged by decreased turbidity, in improved compatibility of the surfactant system in injectates made with water sources comprising salts.
