摘要： A method includes treating a reservoir with a damaged near wellbore region (NWR), including introducing a liquid foam treatment into a wellbore proximate to the damaged NWR, where the liquid foam treatment has a solution medium and nanobubbles, transmitting an acoustic wave towards the damaged NWR such that the nanobubbles collapse, causing fluid flow pathways to form for hydrocarbon production.
A system includes a solution generation tool for generating a liquid foam treatment, where the liquid foam treatment has a solution medium and nanobubbles, where the nanobubbles migrate along a concentration gradient, and an acoustic signal generator transmits an acoustic signal. The system also includes a downhole tool signally coupled to the acoustic signal generator fluidly coupled to the solution generation tool, and the downhole tool transmits an acoustic wave into an NWR and introduces the liquid foam treatment into the wellbore proximate to the NWR.-

摘要： A method and a system for characterizing subsurface environments using photoacoustic nanotracers are provided herein. An exemplary method for using a photoacoustic nanotracer to characterize a subsurface environment includes forming a solution including a photoacoustic nanotracer, injecting the solution into the subsurface environment, and analyzing produced fluids for the photoacoustic nanotracer. A breakthrough curve is built based, at least in part, on the analysis.

摘要： Subsurface environments can be characterized using photoacoustic nanotracers. A solution including a photoacoustic nanotracer is formed. The solution is injected into the subsurface environment. Produced fluids are analyzed for the photoacoustic nanotracer. A breakthrough curve is built based, at least in part, on the analysis. The photoacoustic nanotracers can be based on plasmonic gold nanoparticles, silver nanoparticles, or both.

摘要： Provided is an injection fluid that may include a nanoemulsion having an oil phase dispersed in an aqueous phase, and non-superparamagnetic magnetic nanoparticles that are present in the dispersed oil phase. Further provided is a method for preparing an injection fluid that may include preparing a nanoemulsion from an aqueous phase and an oil phase having non-superparamagnetic magnetic nanoparticles therein, and may be used to form nanodroplets of the non-superparamagnetic magnetic nanoparticles. Further provided is a method for tracking movement of an injection fluid. The method may include introducing a tagged injection fluid into a hydrocarbon-containing reservoir, the tagged injection fluid may be a nanoemulsion that includes: an aqueous phase, an oil phase dispersed in the aqueous phase, and non-superparamagnetic nanoparticles that are present in the dispersed oil phase; and tracking the movement of the tagged injection fluid.

摘要： A single well chemical tracer composition comprising core/shell tracer particles and an aqueous fluid is provided. The core/shell tracer particles have a core and a polymer shell. At least two tracer chemicals are encapsulated in the core/shell tracer particles. A method of determining residual oil in a reservoir is also provided. The method includes introducing a tracer fluid having the core/shell tracer particles into a wellbore. The reservoir is then maintained for a period of time such that the core/shell particle is ruptured, and the tracer chemicals are released into the reservoir. Then, the method includes producing a produced fluid from the reservoir, measuring the quantity of the tracer chemicals in the produced fluid, and determining a residual oil content of the reservoir based on the measured quantity of the tracer chemicals in the produced fluid.
