Claims12
A method of treating an oil and/or gas well having a wellbore, comprising:
- injecting a solution into the wellbore, wherein the solution comprises a microemulsion,
- wherein the microemulsion is a homogeneous thermodynamically stable single phase comprising:
- a water continuous phase,
- between about 1 wt % and about 95 wt % water;
- between about 1 wt % and about 30 wt % of a solvent, wherein the solvent comprises a first solvent and a second solvent, the first solvent comprising a terpene solvent and the second solvent comprising an alkane;
- between about 0 wt % and about 50 wt % alcohol;
- and
- between about 1 wt % and 90 wt % surfactant, versus the total microemulsion.
