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 methyl aliphatic carboxylic acid ester; and
an alcohol having from 1 to 8 carbon atoms comprising amyl alcohol, butyl 3-hydroxybutanoate, or a combination thereof.

2. The composition of claim 1 , further comprising an alcohol having 1 to 8 carbon atoms.

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

4. The composition of claim 1 , further comprising a glycol.

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

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

7. The composition of claim 3 , wherein the terpene alcohol comprises alpha-terpineol.

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 1 , wherein the alcohol comprises amyl alcohol.

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

11. The composition of claim 7 , wherein the solvent further comprises a terpene.
