Abstract

A flow improver composition may include a branched dendritic core having a first quaternary carbon center bonded to four second carbon atoms, where in at least three of the four second carbon atoms are individually bonded to one or more chain extender ligands to produce the branched dendritic core, wherein the branched dendritic core has greater than or equal to about 16 terminal hydroxyl groups, wherein at least one terminal hydroxyl group is esterified with at least one carboxylic acid moiety comprising of 6 to 30 carbon atoms or a combination, and wherein the dendritic core has no nitrogen atom; a polymeric inhibitor having an alkyl side chain of 2 to 40 carbon atoms; and an aromatic solvent.

Claims (18)

1. A flow improver composition, comprising: a branched dendritic core having a first quaternary carbon center bonded to four second carbon atoms, where in at least three of the four second carbon atoms are individually bonded to one or more chain extender ligands to produce the branched dendritic core, wherein the branched dendritic core has greater than or equal to about 16 terminal hydroxyl groups, wherein at least one terminal hydroxyl group is esterified with at least one carboxylic acid moiety comprising of 6 to 30 carbon atoms or a combination, and wherein the dendritic core has no nitrogen atom; a polymeric inhibitor having an alkyl side chain of 2 to 40 carbon atoms; and an aromatic solvent.
2. The flow improver composition, wherein the branched dendritic core is present in an amount ranging from 0.1 wt.% to 10 wt.%.
3. The flow improver composition of claim 1, wherein the polymeric inhibitor is present in an amount ranging from 0.1 wt.% to 15 wt.%.
4. The flow improver composition, further comprising: a surfactant in an amount ranging from 0.1 wt.% to 20 wt.%.

6. The flow improver composition of claim 1, wherein aromatic solvent is present in an amount ranging from 20 wt.% to 80 wt.%
7. The flow improver composition, wherein the polymeric inhibitor comprises a copolymer of styrene and the maleic anhydride monomer esterified with a C6 to C30 alkyl group.
8. The flow improver composition of claim 7, wherein the C6 to C30 alkyl group is present in an amount greater than a ratio of 1.5:1 relative to the maleic anhydride monomer.
9. The flow improver composition of claim 1, wherein the polymeric inhibitor comprises a polymer or copolymer comprising an alkyl acrylate monomer having a C6 to C30 alkyl group.
10. The flow improver composition of claim 1, wherein the polymeric inhibitor comprises an ethylene vinyl acetate copolymer.
11. The flow improver composition of claim 1, wherein the alkyl side chain ranging from 6 to 30 carbon atoms.
12. A method comprising: adding the flow improver composition of claim 1 to a first hydrocarbon fluid to produce a second hydrocarbon fluid.
13. The method of claim 12, wherein the first hydrocarbon fluid is a hydrocarbon fluid produced during extraction of hydrocarbons from a well, crude oil, a crude oil condensate, a middle distillate, a fuel oil, diesel, or a combination thereof.
14. The method of claim 12, further comprising adding the flow improver to the first hydrocarbon fluid in a well.
15. A method comprising: extracting a hydrocarbon fluid from a well; adding the flow improver composition of claim 1 to the hydrocarbon fluid.
16. The method of claim 15, wherein the composition is added to the hydrocarbon fluid prior to the hydrocarbon fluid being extracted from the well.
17. The method of claim 15, wherein the composition is added to the hydrocarbon fluid after the hydrocarbon fluid has been extracted from the well.
18. The method of claim 15, wherein the flow improver is added to the hydrocarbon fluid while the hydrocarbon fluid is extracted from the well.
