摘要： Described herein are environmentally acceptable fluid compositions, and methods and systems of using the fluids for restoring or enhancing hydrocarbon flow from a well bore. In some embodiments the fluids can be used to decrease the viscosity of a high viscosity hydrocarbon such as heavy crude oil. In other embodiments, the fluids may be used to aid in releasing a hydrocarbon from a geologic formation. In other embodiments, the fluids may be used to restore flow from a wellbore located at or near a geologic formation with a significant concentration of clay. In some embodiments, the disclosed fluids may be used with one or more viscosity-modifying compounds. The disclosed compositions may help decrease the concentration of water within the formation while increasing the concentration of methanol within the formation, which may aid in restoring cracks and fissures in the formation, increasing the size of the cracks and fissures, or increasing the number of cracks and fissures within the formation.
