Methods of obtaining hydrocarbons using suspensions including organic bases

摘要

Suspensions comprising an organic base and at least one carrier fluid. The organic base comprises an amine group and at least one hydrophobic group attached to the amine group. The at least one hydrophobic group may be functionalized with one or more functional groups. Methods of extracting and obtaining a hydrocarbon material from a subterranean formation or bitumen using the suspension are disclosed.

1. A method of obtaining a hydrocarbon material, the method comprising:
combining an organic base with a carrier fluid to form a suspension, the organic base selected from the group consisting of at least one of propylene diamine, butylene diamine, poly(vinylpyridine), polyvinyl imidazole, polyacrylamide, poly(N-isopropylacrylamide), tripropylamine, dibutylamine, tributylamine, and combinations thereof, wherein the organic base reacts with an acid at a temperature greater than about 250° C.; contacting at least one of a subterranean formation comprising bitumen or a slurry comprising bitumen with the suspension to form an emulsion comprising at least one of a cationic surfactant and an anionic surfactant, the organic base, and the carrier fluid; and separating a hydrocarbon material from the emulsion.
