摘要： A method for enhancing oil recovery includes the step of providing a subsurface reservoir containing hydrocarbons therewithin. A wellbore is provided in fluid communication with the subsurface reservoir. A surfactant-polymer solution is formed for injection into the reservoir. The surfactant-polymer solution is formed by mixing a composition with at least one surfactant, at least one polymer, and at least one co-solvent or co-surfactant such that the surfactant-polymer solution is clear and aqueous stable. The surfactant-polymer solution is injected through the wellbore into the reservoir. A chaser solution is formed for injection into the reservoir. The chaser solution has an additional predetermined quantity of the co-solvent or co-surfactant. The chaser solution is injected through the injection wellbore into the reservoir to increase the production of hydrocarbons from the reservoir while maintaining the clear and aqueous stability of the surfactant-polymer solution.

摘要： A method for preventing scale formation during an alkaline hydrocarbon recovery process is disclosed. An aqueous solution (e.g., recovered sea water, water produced from the subterranean reservoir, or a combination thereof) having a concentration of metal cations (e.g., calcium, magnesium) is provided. A stoichiometric amount of an organic complexing agent relative to the concentration of metal cations is introduced into the aqueous solution such that the organic complexing agent forms aqueous soluble cation-ligand complexes with the metal cations. At least one alkaline is introduced into the aqueous solution to form an injection fluid having a pH value of at least 10. The cation-ligand complexes remain soluble in the injection fluid such that scale formation is prevented when the injection fluid is injected into a subterranean reservoir.

摘要： A method for retaining a treatment chemical in a subterranean formation containing hydrocarbons is disclosed. The method includes first preparing an emulsion. The emulsion contains an oil continuous phase and first and second aqueous phases. The first aqueous phase includes a treatment chemical, such as a scale inhibitor. The second aqueous phase comprises a retention enhancing chemical which is to be reacted with the treatment chemical in the subterranean formation. Preferably, the first and second aqueous phases remain generally separately dispersed and stable within the oil continuous phase prior to being introduced into the subterranean formation. The emulsion is then placed down a well bore and into the subterranean formation. The first and second aqueous phases then interact with one another in the subterranean formation such that the treatment chemical and the retention enhancing chemical react with one another resulting in the treatment chemical being retained in the subterranean formation at a greater efficiency than had the second aqueous phase, including the retention enhancing chemical, not been used.
