1. An emulsion or a microemulsion for stimulating an oil or gas well, comprising:
- an aqueous phase;
a surfactant, wherein the surfactant is present in an amount between about 15 wt % and about 55 wt % versus the total composition;
a freezing point depression agent, wherein the freezing point depression agent is present in an amount between about 5 wt % and 40 wt % versus the total composition; and
an oil continuous phase being a terpene, wherein the terpene is nopol and wherein the nopol is present in an amount between about 5 wt % and about 40 wt % versus the total composition, and wherein the ratio of water to terpene is between about 3;
1 and about 1;

Abstract
Methods and compositions for stimulating of the production of hydrocarbons (e.g., formation crude oil and/or formation gas) from subterranean formations are provided. In some embodiments, the compositions are emulsions or microemulsions, which may include water, a terpene, and a surfactant. In some embodiments, methods of selecting a composition for treating an oil or gas well are provided.
