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.

First claim

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, a linear oleaginous hydrocarbon solvent, a branched oleaginous hydrocarbon solvent, a cyclic oleaginous hydrocarbon solvent, a saturated oleaginous hydrocarbon solvent, an unsaturated oleaginous hydrocarbon solvent, or a combination thereof; and an alcohol having from 1 to 8 carbon atoms.

2 . The composition of claim 1 , wherein the alcohol comprises butanol, pentanol, amyl alcohol, butyl 3-hydroxybutanoate, or combinations thereof.

3 . The composition of claim 1 , wherein the alcohol comprises amyl alcohol, butyl 3-hydroxybutanoate, or a combination thereof.

4 . The composition of claim 3 , wherein the solvent comprises a first solvent comprising a terpene and a second solvent comprising a linear oleaginous hydrocarbon solvent, a branched oleaginous hydrocarbon solvent, a cyclic oleaginous hydrocarbon solvent, a saturated oleaginous hydrocarbon solvent, an unsaturated oleaginous hydrocarbon solvent, or combinations thereof.

5 . The composition of claim 4 , wherein the terpene comprises dipentene and/or d-limonene.

6 . The composition of claim 5 , wherein the terpene comprises dipentene and d-limonene.

7 . The composition of claim 1 , wherein the solvent comprises a first solvent comprising a terpene and a second solvent comprising a linear oleaginous hydrocarbon solvent, a branched oleaginous hydrocarbon solvent, a cyclic oleaginous hydrocarbon solvent, a saturated oleaginous hydrocarbon solvent, an unsaturated oleaginous hydrocarbon solvent, or combinations thereof.

8 . The composition of claim 1 , wherein the solvent comprises the terpene, wherein the terpene comprises dipentene.

9 . The composition of claim 1 , wherein the solvent comprises the terpene, wherein the terpene comprises d-limonene.

10 . The composition of claim 1 , wherein the solvent comprises the terpene, wherein the terpene comprises dipentene and d-limonene.

11 . The composition of claim 1 , wherein the alcohol is present in an amount between about 2 wt % and about 15 wt % versus the microemulsion.

12 . The composition of claim 1 , wherein the microemulsion further comprises an additional alcohol having 1 to 8 carbon atoms.

13 . The composition of claim 1 , wherein the solvent further comprises a terpene alcohol.

14 . The composition of claim 13 , wherein the terpene alcohol comprises alpha-terpineol.

15 . The composition of claim 1 , wherein the microemulsion further comprises a glycol.

16 . The composition of claim 1 , wherein the solvent further comprises linalool, geraniol, nopol, alpha-terpineol, menthol, eucalyptol, or combinations thereof.

17 . The composition of claim 1 , wherein the solvent further comprises an alcohol, an aldehyde, an ether, or a ketone group.

18 . The composition of claim 1 , wherein the alcohol comprises amyl alcohol.

19 . The composition of claim 1 , wherein the alcohol comprises butyl 3-hydroxybutanoate.

20 . The composition of claim 1 , wherein the solvent comprises the terpene.
