Abstract: Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations (tight shale reservoirs). The flowback compositions include an anionic dimer surfactant, an anionic monomer surfactant, and a demulsifier. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.

Abstract: The present disclosure generally relates to compositions and uses of sulfidogenesis inhibitor compounds of Formulae 1 and 2 for preventing sulfidogenesis, i.e., the reduction reaction of a sulfur-containing compound by sulfur-utilizing prokaryotes that produce sulfide species such as hydrogen sulfide, during enhanced oil recovery processes. A method for inhibiting or decreasing microbial sulfide production by sulfur-utilizing prokaryotes includes addition of an effective amount of sulfidogenesis inhibitor compounds of Formulae 1 and 2 to the fluid that is injected into a sulfidogenic reservoir system during enhanced oil recovery. For example, the compounds can be used as sulfidogenesis inhibitors in a water injection system for use in a hydrocarbon extraction system or a hydrocarbon production system. Thus, these compositions can be effectively used as inhibitors of biogenic hydrogen sulfide generation in oilfield fluids.

Abstract: A continuous inverse emulsion polymerization process may involve combining an aqueous monomer composition with an oil composition in a premix vessel and allowing the aqueous monomer composition to interact with the oil composition in the premix vessel for a period of time effective to form a stable pre-emulsion. The stable pre-emulsion may then be homogenized to form a homogenized emulsion that is then polymerized to form a water-in-oil inverse emulsion polymer. By forming a stable pre-emulsion that is then homogenized, the resulting water-in-oil inverse emulsion polymer may have uniform and consistent polymer size distribution.

The fluorescence measurement methods are similarly useful to quantify mixtures of tagged and untagged water source treatment compounds or polymers present in an industrial water source.

Abstract: Graphene quantum dots are functionalized by covalently bonding a corrosion inhibitor molecule thereto. In a useful method, a corrosion inhibitor compound is blended with a graphene quantum dot-tagged corrosion inhibitor compound, and the blend is applied to a metal surface, such as the interior of a carbon steel pipe. The blend inhibits corrosion arising from contact with produced water generated by hydrocarbon recovery from one or more subterranean reservoirs. The produced water having the blend dispersed therein is irradiated with a source of light having a selected first range of wavelengths, and the luminescent emission of the graphene quantum dot-tagged corrosion inhibitor is measured at a selected second range of wavelengths, thereby providing for real-time measurement of corrosion inhibitor concentration within the pipe.
