FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method of investigating the efficacy of a potential stabilizer of asphaltenes, wherein said method comprises producing reconstituted oil by dispersing a solid substance containing asphaltene in a hydrocarbon fluid, where asphaltene-containing solid substance is a solid substance which precipitates from crude oil, preferably during extraction, transportation or processing, and hydrocarbon fluid medium is commercial tank oil, addition of potential stabilizer of asphaltenes to recovered oil to produce modified oil and stability analysis of asphaltenes in modified oil.
EFFECT: methods of analyzing asphaltene stabilizers are disclosed.
