Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A composition for use in an oil and/or gas well having a wellbore, comprising a microemulsion, wherein the microemulsion comprises: an aqueous phase; a surfactant comprising alkyl polyglycoside; a solvent comprising a terpene and a linear oleaginous hydrocarbon solvent; and an alcohol having from 1 to 8 carbon atoms, wherein the alcohol comprises butyl 3-hydroxybutanoate. 2. The composition of claim 1 , wherein the alcohol further comprises butanol, pentanol, amyl alcohol, or combinations thereof. 3. The composition of claim 1 , wherein the alcohol further comprises amyl alcohol. 4. The composition of claim 1 , wherein the terpene comprises dipentene or d-limonene. 5. The composition of claim 1 , wherein the terpene comprises dipentene and d-limonene. 6. The composition of claim 1 , wherein the terpene comprises dipentene. 7. The composition of claim 1 , wherein the terpene comprises d-limonene. 8. The composition of claim 1 , wherein the alcohol is present in an amount between about 2 wt % and about 15 wt % versus the microemulsion. 9. The composition of claim 8 , wherein the terpene comprises dipentene and d-limonene. 10. The composition of claim 1 , wherein the microemulsion further comprises an additional alcohol having 1 to 8 carbon atoms. 11. The composition of claim 1 , wherein the solvent further comprises a terpene alcohol. 12. The composition of claim 11 , wherein the terpene alcohol comprises alpha-terpineol. 13. The composition of claim 1 , wherein the microemulsion further comprises a glycol. 14. The composition of claim 1 , wherein the solvent further comprises linalool, geraniol, nopol, alpha-terpineol, menthol, eucalyptol, or combinations thereof. 15. The composition of claim 1 , wherein the solvent further comprises an alcohol, an aldehyde, an ether, or a ketone group.
