Abstract: A method to improve the efficiency of a gravity drainage CO2 gas injection process includes the steps of: (a) injecting a slug proximate to an underground reservoir, wherein the slug comprises a polymer component and an inorganic metal ion type crosslinking agent that are configured to form an in situ weak gel in the reservoir to block high permeability channels in a pay zone of the reservoir; and (b) continuously injecting CO2 gas at a top of the pay zone to form a gas cap at the top of the reservoir and to cause the gas cap to advance rapidly towards a producing well located below to provide a uniform sweep of the gas cap.

Abstract: A method and a system for oil recovery are provided. An exemplary method includes injecting thickened carbon dioxide (CO2) into the top of a reservoir containing oil. An interface is formed between the thickened CO2 and the oil. The oil is mobilized by the thickened CO2. The mobilized oil is recovered with a recovery well drilled below the reservoir.

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: 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.

The cation-containing surfactant includes at least one of a single positively charged cation-containing surfactant, a double positively charged cation-containing surfactant and a zwitterionic cation-containing surfactant. A method for inhibiting scale formation in a wellbore includes introducing a phosphonate compound, a cation-containing surfactant and an aqueous fluid to the wellbore to produce a scale inhibitor fluid.
