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: A sag flow loop may include: a test section; a pump configured to at least pump fluid containing particles suspended therein at variable rates through the sag flow loop including the test section, the variable rates inducing formation of a bed of particles settled out of the fluid in the test section; and a flow meter densitometer configured to measure density of the fluid flowing through the sag flow loop. The sag flow loop may be configured to determine a sag of the particles in the fluid. The pump, the flow meter densitometer, and the test section may be connected via flowlines. The sag flow loop may have a volumetric capacity of less than four liters.
