Abstract

Delayed breakers are given that break viscoelastic surfactant fluids inside the pores of formations into which the fluids have been injected. The breakers comprise proteins, proteins that contain breakers, or cells that contain breakers. Proteins become breakers, and proteins and cells release breakers, due to a triggering mechanism that may be, for example, a change in temperature, pH, or salinity.

Claims

1. A method of treating a subterranean formation penetrated by a wellbore comprising a) injecting into the formation a fluid comprising a non-polymeric viscosifier that acts by creating a three dimensional structure in the fluid, and a breaker comprising a protein, and b) allowing said protein to denature and disrupt said structure, wherein said protein is selected from the group consisting of fibrous proteins and globular proteins.
2. The method of claim 1 wherein said fibrous proteins are selected from the group consisting of cytoskeletal proteins and extracellular matrix proteins.
3. The method of claim 1 wherein said globular proteins are selected from the group consisting of plasma proteins, coagulation factors, hemoproteins, hormones, DNA-binding proteins, and immune system proteins.
4. The method of claim 1 wherein said non-polymeric viscosifier comprises a viscoelastic surfactant.
5. The method of claim 4 wherein said viscoelastic surfactant is selected from a betaine and an amidoamine oxide.
6. The method of claim 1 wherein said protein comprises egg white.
7. The method of claim 6 wherein said fluid further comprises a sugar or sugar alcohol.
8. The method of claim 7 wherein said sugar or sugar alcohol is selected from sucrose, d- fructose, and d-sorbitol.
9. The method of claim 1 wherein said step of allowing said protein to disrupt said structure is delayed by enclosing said protein in a member selected from the group consisting of fatty acids, polyvinyl alcohols, synthetic resins, phenolic resins, aery late polymers and copolymers, lactic acid and glycolic acid polymers and copolymers, and mixtures thereof.
10. A method of treating a subterranean formation penetrated by a wellbore comprising a) injecting into the formation an aqueous fluid comprising a non-polymeric viscosifier that acts by creating a three dimensional structure in the fluid, and a globular protein enclosing a breaker for said viscosifier, and b) allowing said protein to denature and release said breaker.
11. The method of claim 10 wherein said globular protein is selected from albumins, caseins, and glutens.
12. The method of claim 10 wherein said breaker is selected from the group consisting of long chain alcohols, tatty acids, fatty acid esters, mono, di or triglicerides of fatty acids, long chain alcohol phosphate esters, diacid esters, aliphatic hydrocarbons, aromatic hydrocarbons, and mixtures thereof.
13. A method of treating a subterranean formation penetrated by a wellbore comprising a) injecting into the formation an aqueous fluid comprising a non-polymeric viscosifier that acts by creating a three dimensional structure in the fluid, and a breaker comprising an enzyme having a secondary, tertiary or quaternary structure which can be altered by a condition that the fluid will experience in the wellbore, and b) allowing said protein to denature and disrupt said structure.
14. The method of claim 13 wherein said enzyme is selected from the group consisting of oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases.
15. The method of claim 13 wherein said enzyme comprises alpha-amylase.
16. The method of claim 13 wherein said condition is selected from the group consisting of pH, temperature, salinity, solvent or pressure.
17. The method of claim 13 wherein said fluid further comprises a sugar or sugar alcohol.
18. The method of claim 18 wherein said sugar or sugar alcohol is selected from sucrose, d- fructose, and d-sorbitol.
9. The method of claim 13 wherein said step of allowing said enzyme to disrupt said structure is delayed by enclosing said enzyme in a member selected from the group consisting of fatty acids, polyvinyl alcohols, synthetic resins, phenolic resins, aery late polymers and copolymers, lactic acid and glycolic acid polymers and copolymers, and mixtures thereof.
