Abstract: Spherical grains and sacrificial particles are mixed in a suspension. The sacrificial particles are larger than the spherical grains. The suspension is injected into a channel in a microfluidic chip, and the spherical grains form microporous structures in the channel. The microporous structures are sintered in the channel. A solvent is injected into the channel, and the solvent dissolves the sacrificial particles and forms macropores between at least some of the microporous structures, thereby forming a mixed-porosity microfluidic chip.

Abstract: A carbonate microfluidic model with controllable nanoscale porosity and methods are described. The method for fabricating a carbonate nanofluidic micromodel with controllable nanoscale porosity for studying fluid behaviors in an underground oil-reservoir environment includes: disposing a plurality of polymer spheres into a transparent flow cell; initiating crystallization of the plurality of polymer spheres to form a template with an opal structure; filling the transparent flow cell with a calcium-based solution and a carbonate-based solution to form nanocrystals in voids of the opal structure; and removing the template formed by crystallization of the plurality of polymer spheres from the transparent flow cell leaving an inverse opal structure with a plurality of nanoscale pores and a carbonate surface. The model includes: a transparent flow cell including a first end defining an inlet and a second end defining an outlet; and an inverse opal structure of carbonate inside the transparent flow cell.

Abstract: A method for reducing condensate in a subsurface formation is disclosed. The method includes introducing a reactive mixture including an aqueous solution, urea, dopamine, a silica nanoparticle precursor, a silane grafting compound, and an alcohol compound into the subsurface formation. The method also includes allowing generation of ammonia through thermal decomposition of the urea and allowing the silica nanoparticle precursor to hydrolyze, thereby forming silica nanoparticles. The method further includes allowing the silane grafting compound to graft onto the silica nanoparticles, thereby forming functionalized silica nanoparticles. The method also includes allowing polymerization of the dopamine, thereby forming polydopamine. The method also includes allowing the functionalized silica nanoparticles to attach to the subsurface formation via the polydopamine, thereby reducing condensate in the subsurface formation.

Abstract: The present disclosure describes methods and systems for detecting a multi-modal tracer in a hydrocarbon reservoir. One method includes injecting a multi-modal tracer at a first location in a reservoir, wherein the multi-modal tracer mixes with subsurface fluid in the reservoir; collecting fluid samples at a second location in the reservoir; and analyzing the fluid samples to detect a presence of the multi-modal tracer in the fluid samples.

Abstract: Optical properties of a tracer in water are measured at varying concentrations. A reference curve is built based on the measured optical properties at varying concentrations. An emulsion is mixed with the tracer. The emulsion is demulsified into an oil component and an aqueous component. Optical properties of one of the components are measured. A partition coefficient is determined based on the measured optical properties of a demulsified component and the reference curve.

Abstract: The disclosure relates to fluorescent fibers and methods of making and using the fluorescent fibers. The fluorescent fibers can be made using natural sourced materials and green chemistry methods. The fluorescent fibers can be used as a tracer in mud logging applications by tagging drill cuttings with the fluorescent fibers at a drill bit during a drilling process, or as tracers in fracturing fluids for tracing the gas flow in a gas reservoir.

Abstract: Devices for chemical analysis include a first separation element formed on the substrate, the first separation element having a wicking surface that separates water from hydrocarbons in a fluid sample, a hydrophobic barrier at least partially surrounding the first separation element, a second separation element fluidically connected the first separation element, the second separation element configured to trap salts and organic matter present in the fluid sample, and a detection element fluidically connected to the second separation element, the detection element having a surface that binds with one or more analytes that may be present in the fluid sample and thereby emits a signal that is capable of being optically detected by a detector. Methods include providing such a device for chemical analysis, placing the fluid sample on the first separation element, and detecting the signal emitted by the detection element.

Abstract: Described is a polymer-based well tracer. The polymer-based well tracer is a fluoropolymer having a fluorinated group. The fluoropolymer may be formed into a particle, a coating for proppant particulates, or encapsulated in a polymeric resin. Upon degradation or hydrolysis of the fluoropolymer, the fluorinated group having a fluorinated compound is released within the well.
