    Abstract: A wellbore fluid treatment may include a compound formed from reaction between cyclic anyhydride pendant groups on a polymer backbone with at least one amino acid, neutralized with a nitrogen containing compound. Methods may include injecting such a compound into a hydrogen production stream. Other methods may include reacting polybutadiene grafted maleic anhydride with at least one amino acid to produce an intermediate; and reacting the intermediate with an amide, amine, or imidazoline having at least a C4-C24 group to produce a compound.

    Abstract: Methods may include emplacing into a hydrocarbon production stream a composition containing an asphaltene inhibitor, wherein the asphaltene inhibitor includes the formula: wherein R1 is an alkyl chain having a carbon number in the range of greater than 40 to 200, R2 is a multiester group, R3 is hydrogen, an ion, or an alkyl chain having a carbon number in the range of 1 to 200, m is an integer selected from 0 to 4, and n is an integer selected from the range of 0 to 4, wherein the sum of m and n is 1 or greater. Methods may also include emplacing in a wellbore a composition containing an asphaltene inhibitor, wherein the asphaltene inhibitor comprises esters of the formula: wherein R1 is an alkyl chain having a carbon number in the range of greater than 40 to 200; R2 is a multiester group; is hydrogen, an ion, or an alkyl chain having a carbon number in the range of 1 to 200; m is an integer selected from 0 to 4; and n is an integer selected from the range of 0 to 4, wherein the sum of m and n is 1 or greater.

    Abstract: Compositions may include an asphaltene dispersant that is the product of a reaction between a polysaccharide having at least two sugar subunits and one or more fatty acid reagents, and a petroleum fluid produced from a subterranean formation and containing asphaltenes therein. The asphaltene dispersant may have a molecular weight of at least 4000 Da. Compositions may further include an aromatic solvent. Methods may include contacting a hydrocarbon fluid with an asphaltene dispersant dissolved in an aromatic solvent, wherein the asphaltene dispersant is the product of the reaction of a polysaccharide and one or more fatty acid reagents. Methods may also include contacting a hydrocarbon fluid with an asphaltene, wherein the asphaltene dispersant is the product of the reaction of a polysaccharide and one or more fatty acid reagents and has a molecular weight of at least 4000 Da.

    Abstract: Embodiments relate to fluid flow improvers containing a copolymer with a siloxane group incorporated thereto. The fluid flow improvers may include polymer/copolymer having the characteristic of inhibiting wax/paraffin crystalline growth, modifying wax/paraffin crystal growth, dispersing of wax/paraffin, preventing the deposition of wax/paraffin, aiding the removal of wax/paraffin or depressing of the pour point of a wax/paraffin-containing fluid. The fluid flow improvers described may be employed alone, or may be used in combination with one or more additives for improving the low temperature flowability and/or other properties and may also be employed in combination with one or more organic solvents and/or aqueous solvents.
