Asphaltene destabilization during solvent-based heavy oil and bitumen recovery applications is a common problem due to continuous changes of temperature, pressure, and oil composition. The effects of these characteristics on the recovery performance should be investigated for a wide range of solvent and oil types. In this paper, two heavy oil samples from fields in Alberta, Canada were destabilized...
Due to inefficiency of steam injection caused by technical, economic, and operational reasons, solvent methods have received special attention in heavy oil and bitumen recovery recently. Solvent-based recovery processes improves crude oil production and quality because underground in situ upgrading takes place after heavy oil is diluted with a light hydrocarbon solvent. Consequently, crude oil mobility...
