    Abstract: The systems and method described in this specification relate to at least partially restoring carbonate core samples. The systems and methods include extracting a carbonate core sample from a subterranean formation. The extracted carbonate core sample is inserted into a core flooding test machine. A first brine permeability of the extracted carbonate core sample is measured. A fluid is pumped through the extracted carbonate core sample to flood the carbonate core sample. The fluid includes at least one of a high-molecular weight polymer solution and a gel particle solution. The systems and methods include at least partially restoring the porosity and the brine permeability of the flooded carbonate core sample by pumping an oxidizing solution through the carbonate core sample and heating the carbonate core sample to a temperature of at least 60° C. after pumping the oxidizing solution through the carbonate core sample.

    IPC: C09K8/584

    Abstract: Provided is a composition that may include a mixture of an ionic liquid and a surfactant in an aqueous composition, where a carbonaceous hydrocarbon-bearing formation has a wettability value and comprises hydrocarbons, where there is an interfacial tension value between the aqueous composition and hydrocarbons present in the carbonaceous hydrocarbon-bearing formation, where the aqueous solution may be configured to modify the wettability value of the carbonaceous hydrocarbon-bearing formation from a first value to a second value that is more water-wet than the first value, and where the presence of the ionic liquid in the aqueous composition may not substantially impact the value for interfacial tension between the hydrocarbons in the carbonaceous hydrocarbon-bearing formation and the aqueous composition. Further provided is a method that may introduce the aqueous composition into a carbonaceous hydrocarbon-bearing formation.

    Abstract: Compositions that include cationic surfactants and methods of synthesizing compositions that include cationic surfactants. The surfactants include a quaternary amine and a saturated or unsaturated alkyl chain with 4 to 28 carbons. The surfactants can be generated by reacting a fatty acid modified with an amino alkyl group and an epihalohydrin in the presence of a base. The cationic surfactants can be generated by reacting a fatty acid modified with an amino alkyl group, an epihalohydrin, and a carboxylic acid. The cationic surfactants can be generated by reacting a carboxylic acid, an epihalohydrin, and a catalyst to afford a halo-substituted alkyl ester, followed by reacting the halo-substituted alky ester with a fatty acid modified with an amino alkyl group.

    Abstract: Surfactant mixtures include a cationic surfactant, an anionic surfactant, and a nonionic surfactant in a brine solution. The cationic surfactant may include at least one quaternary ammonium, at least one brominated trimethylammonium, or combinations thereof. The anionic surfactant may include at least one organosulfate. The nonionic surfactant may include the nonionic surfactant comprised of a polyoxyethylene fatty acid ester, a phenylated ethoxylate, or combinations thereof. The surfactant mixtures may be incorporated into methods for reducing the interfacial tension between the surfactant mixture and oily fluids during chemical enhanced oil recovery. The methods for reducing the interfacial tension may include introducing the surfactant mixture comprising a cationic surfactant, an anionic surfactant, and a nonionic surfactant in a brine solution to a hydrocarbon-bearing reservoir, thereby reducing the interfacial tension at a liquid-liquid interface of the surfactant mixture and the fluid.

    Abstract: The subject matter of this specification can be embodied in, among other things, a system that includes a three-dimensional fabricator. An image processing module acquires an image of a rock sample having a network of pores, a transformation module transforms the image into a binary matrix and determine a set of statistical moments of the binary matrix, a layer generation module generates a first representation of a first stochastic layer based on the set and emulative of the rock sample and generates a second representation of a second stochastic layer based on the set and emulative of the rock sample. An arrangement module arranges the first representation and the second representation as adjacent layers of a three-dimensional model emulative of the rock sample, and provides the first representation and the second representation to the 3D fabricator for fabrication as a physical three-dimensional fluid micromodel emulative of the rock sample.
