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.

Claims

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, an alkyl aliphatic carboxylic acid ester, 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, an alkyl aliphatic carboxylic acid ester, or combinations thereof; and

an oxygenated co-solvent.

2. The composition of claim 1, wherein the oxygenated co-solvent comprises an alcohol having 1 to 8 carbon atoms.

3. The composition of claim 1, wherein the oxygenated co-solvent comprises a terpene alcohol.

4. The composition of claim 1, wherein the oxygenated co-solvent comprises a glycol.

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

6. The composition of claim 1, wherein the solvent comprises the alkyl aliphatic carboxylic ester and further comprises a methyl aliphatic carboxylic acid ester.

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

8. The composition of claim 1, wherein the solvent comprises the terpene and further comprises alpha-terpineol.

9. The composition of claim 2, wherein the alcohol having 1 to 8 carbon atoms comprises butanol, amyl alcohol, or combinations thereof.

10. The composition of claim 2, wherein the alcohol having 1 to 8 carbon atoms is present in an amount between about 2 wt % and about 15 wt % versus the microemulsion.
