Abstract: A method includes introducing a fluoro-based small molecule tracer into a stimulation fluid, injecting the stimulation fluid into a target zone of a subterranean formation, and maintaining the fluoro-based small molecule tracer inside the target zone of the subterranean formation for an amount of time. While being maintained inside the target zone, the fluoro-based small molecule tracer comes into contact with water at a downhole temperature resulting in hydrolysis of the fluoro-based small molecule tracer to produce a fluorinated tracer and a nonfluorinated group. Then, produced fluid that includes the fluorinated tracer is recovered, a concentration of the fluorinated tracer in the hydrocarbons is determined, and the concentration of the fluorinated tracer is correlated to a productivity of the target zone of the subterranean formation.

Abstract: Techniques for treating a hydrocarbon reservoir include delivering a composition to the hydrocarbon reservoir. The composition includes at least one acid, and liquid or supercritical carbon dioxide (CO2). The method further includes exposing the delivered composition to water to activate the composition; and treating a rock formation of the hydrocarbon reservoir with the activated composition.

Abstract: A method and hydraulic fracturing fluid that is a viscoelastic surfactant (VES) fracturing fluid having a surfactant and an inorganic oxidizer salt for hydraulic fracturing of a geological formation. The VES fracturing fluid is provided through a wellbore into the geological formation to hydraulically fracture the geological formation to form hydraulic fractures in the geological formation. The method includes oxidizing organic material in the hydraulic fractures with the VES fracturing fluid.
