    Abstract: The present disclosure relates to compositions and methods for prevent the formation of and disperse aggregates and other poorly soluble materials in hydrocarbon fluids. The compositions include an asphaltene dispersant prepared from the reaction of a polyethyleneimine (PEI) dendrimer and one or more derivatizing reagents wherein the polyethylene dendrimer has a weight average molecular weight of greater than or equal to 9 kDa. The methods include emplacing in a wellbore a composition comprising an asphaltene inhibitor, wherein the asphaltene inhibitor is a compound prepared from the reaction of a polyethyleneimine dendrimer and one or more derivatizing reagents wherein the polyethylene dendrimer has a weight average molecular weight of greater than or equal to 9 kDa.

    Abstract: Disclosed herein is a fluid flow improver comprising a branched dendritic core comprising a first quaternary carbon center bonded to four second carbon atoms, wherein 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, and wherein at least one of the terminal hydroxyl groups is esterified with at least one carboxylic acid moiety comprising from 6 to 30 carbon atoms. Methods of inhibiting deposition of paraffin and reducing pour point temperature of a hydrocarbon fluid are also disclosed.
