Abstract
Compositions for stimulating hydrocarbon production from a subterranean formation are generally disclosed. In some embodiments, such compositions include olefinic ester compounds, such as alkyl esters of C10-18 unsaturated fatty acids. In some embodiments, the olefinic ester compounds are derived from a natural oil or a natural oil derivative, for example, by catalytic olefin metathesis. Uses of such compounds, such as in oil- and gas-production methods are also generally disclosed.
Claims8
A method of stimulating an oil or gas well, comprising:
- providing a composition comprising olefinic ester compounds, wherein the olefinic ester compounds comprise methyl 9-decenoate, methyl 9-undenenoate, methyl 9-dodecenoate, or mixtures thereof, wherein the composition is an oil-in-water emulsion, and wherein the dispersed phase comprises the olefinic ester compounds and the continuous phase comprises water, wherein the olefinic ester compounds make up at least 50 percent by weight of the dispersed phase;
- and
- introducing the composition into an oil or gas well.
