Abstract
A hydrocarbon recovery composition comprising vinylidene based alkoxylate derivatives. A method of treating a crude oil formation and a method of preparing the hydrocarbon recovery composition are also described.
Claims9
A hydrocarbon recovery composition comprising a derivative selected from the group consisting of a carboxylate, a sulfate and a glycerol sulfonate of an ethoxylated/propoxylated alcohol where the alcohol is produced by hydroformylation of a vinylidene.
A method of treating a formation containing crude oil, comprising:
- (a) providing a hydrocarbon recovery composition to at least a portion of the crude oil containing formation, wherein the composition comprises a derivative selected from the group consisting of a carboxylate, a sulfate and a glycerol sulfonate of an ethoxylated/propoxylated alcohol where the alcohol is produced by hydroformylation of a vinylidene;
- and
- (b) allowing the composition to interact with hydrocarbons in the crude oil containing formation.
A method of preparing a hydrocarbon recovery composition comprising:
- (a) dimerizing one or more alpha olefins to produce one or more vinylidenes;
- (b) hydroformylating the one or more vinylidenes to produce an alcohol;
- (c) ethoxylating and/or propoxylating the alcohol to produce an alkoxylated alcohol;
- and
- (d) reacting the alkoxylated alcohol to form an alkoxylate derivative wherein the derivative is selected from the group consisting of a carboxylate, a sulfate and a glycerol sulfonate.
