Abstract
A composition of a wet hydrocarbon foaming agent including a siloxane can foam wet hydrocarbons. The siloxane wet hydrocarbon foaming agent advantageously foams hydrocarbons that have as little as 5 percent water present and those hydrocarbons having as much as 90 percent water present. The wet hydrocarbon foaming agent can be used in oil and gas production for gas lift and foam blocking applications. The foaming agent can also be used for clearing hydrocarbons from pipelines and other vessels used for transporting oil and gas.
