  • Patent number: 11597873
    Abstract: Compositions and methods comprising certain microemulsions and certain clay control additives for enhancing clay swelling protection and persistency in treating swelling clay of a subterranean formation of oil and/or gas wells are generally provided. The combination of certain microemulsions and certain clay control additives exhibit synergistic effects by enhancing clay swelling protection and persistency in treating swelling clay. The well treatment composition may use up to four times less concentration of clay control additive compared to using the same clay control additive alone, while still providing the same, similar, or higher degree of clay swelling protection and enhanced persistency.

  • Patent number: 11560351
    Abstract: Methods and compositions comprising an emulsion or a microemulsion for use treating an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises an aqueous phase, a solvent, a surfactant comprising alkyl polyglycoside, an alcohol, and, optionally, one or more additives.

  • Patent number: 11512243
    Abstract: Microemulsions comprising an alkyl propoxylated sulfate surfactant and related methods, including methods of use in the treatment of subterranean formations, such as oil and condensate wells, are provided. In some embodiments, the microemulsions and/or methods of use achieve ultra-low interfacial tensions (i.e. less than or equal to 0.01 mN/m) between a wide variety of crude oils and well treatment fluids at various reservoir conditions. In some embodiments, the microemulsion comprises water, an anionic alkyl propoxylated sulfate surfactant, a solvent (e.g., a terpene solvent), and a co-solvent. In some embodiments, the microemulsion further comprises a second and/or third surfactant (e.g., a nonionic and/or an anionic surfactant).
