Abstract: A multicomponent nanocapsule composition comprising a core particle, an oil phase encapsulating the core particle, and an aqueous phase in which the encapsulated core particle is suspended is provided. The porous particle includes a cationic surfactant encapsulated in a porous particle. The oil phase includes an anionic surfactant and a zwitterionic surfactant. A method of making a multicomponent nanocapsule composition is also provided. A method of treating a hydrocarbon-bearing formation with the multicomponent nanocapsule composition is provided. The method may include providing a multicomponent nanocapsule composition, introducing the multicomponent nanocapsule composition into the hydrocarbon-bearing formation, displacing hydrocarbons from the hydrocarbon-bearing formation by contacting the multicomponent nanocapsule composition with the hydrocarbons, and recovering the hydrocarbons.

Abstract: Treatment fluids of the present disclosure may comprise an aqueous base fluid and a surfactant composition. The surfactant composition may comprise a sulfonate surfactant in an amount of from 0.01 wt. % to 2 wt. % based on the total weight of the treatment fluid composition, a plant-based oil in an amount of from 0.01 wt. % to 2 wt. % based on the total weight of the treatment fluid composition, and a zwitterionic co-surfactant in an amount of from 0.01 wt. % to 2 wt. % based on the total weight of the treatment fluid composition. The plant-based oil may comprise from 65 mol. % to 85 mol. % species comprising one or more gondoic acid moieties. Methods for recovering hydrocarbons from a subterranean formation with the treatment fluid are also disclosed.

Abstract: Methods and systems for determining tracer breakthrough from multiple wells commingled at a Gas Oil Separation Plant (GOSP) are provided. An example hydrocarbon reservoir monitoring method includes periodically sampling fluid carried by a water line of a Gas Oil Separation Plant (GOSP). The GOSP is configured to receive commingled well hydrocarbon fluids from multiple wells formed in multiple regions of a hydrocarbon reservoir, separate the well fluids into hydrocarbon components including water, and flow the water through the water line. The multiple regions are tagged with respective tracers. Each tracer is injected into a respective region of the hydrocarbon reservoir surrounding a respective well and can flow into the respective well in response to a well breakthrough. The method also includes analyzing each sampled fluid for one or more tracers of the multiple tracers and monitoring the multiple wells for fluid breakthrough based on results of analyzing each sampled fluid.
