Abstract: Additional oil recovery is obtained from a reservoir with a composition comprising at least a coupling solvent typically employed in waterborne coating compositions. Provided herein are embodiments of methods of recovering hydrocarbons using at least one coupling solvent, such as an oxygenated coupling solvent. The coupling solvent increases the mutual solubility with water at the injection temperature to facilitate the mixing and injection, particularly with an optional co-solvent. The coupling solvent helps mitigate formation plugging and improve performance when injected into a formation, as the solvent mixture moves from being miscible in the injection field water to being miscible in the reservoir oil, mobilizing the reservoir oil to increase oil recovery.

Abstract: In an embodiment of the disclosure, mixtures of different carbon length alcohols are used as the primary feedstock for Guerbet alcohols. Specifically, embodiments relate to a method of synthesizing mixed molecular weight additives from a mixture of primary alcohols comprising, receiving a mixture of primary alcohols having greater than two different chain length primary alcohols and reacting the mixture of primary alcohols in a single reactor to produce a mixture of at least five Guerbet alcohols. The mixture of Guerbet alcohols can then be used to produce an additive or surfactant composition comprising additives or surfactants of different molecular weights.
