REGULATION OF ASPHALTENE PRODUCTION IN A SOLVENT-BASED RECOVERY PROCESS AND SELECTION OF A COMPOSITION OF A HYDROCARBON SOLVENT MIXTURE

摘要

Regulating asphaltene production in a solvent-based recovery process may include determining a bituminous hydrocarbon deposit composition of a bituminous hydrocarbon deposit that includes asphaltenes, selecting a hydrocarbon solvent mixture composition of a hydrocarbon solvent mixture, injecting the hydrocarbon solvent mixture into a solvent extraction chamber, producing a product hydrocarbon stream from the subterranean formation, determining a product hydrocarbon stream asphaltene content of the product hydrocarbon stream, and comparing the product hydrocarbon stream asphaltene content to a target asphaltene content for the product hydrocarbon stream.
