Methods and compositions comprising an emulsion or a microemulsion and a polymer for use in an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives. In certain embodiments, the polymer comprises a copolymer comprising an acrylamide.

Polymers and emulsions for use in oil and/or gas wells

A foam generating surfactant formulation includes a betaine, an alpha-olefin sulfonate and a nanofluid. The betaine is preferably a cocamidopropyl betaine or laurel betaine. The alpha-olefin sulfonate is preferably an anionic surfactant having between 8 and 18 carbon atoms per molecule. The nanofluid is preferably an oil-in-water nanofluid that includes an emulsifying surfactant, a solvent, a co-solvent and water. The addition of the nanofluid increases the thermal stability and salt resistance of the foam generating surfactant.

Surfactant formulations for foam flooding

Methods and compositions comprising an emulsion or a microemulsion for use in various aspects of the life cycle of an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives.
