With the continuous depletion of easy-to produce oil resources, the effective and low-cost
exploitation and upgrading of heavy oil becomes a key to alleviate the contradiction …

Heavy crude oil is one of the most potential fossil fuels at present and in the future. However,
its high viscosity severely hinders its recovery from reservoir conditions. Heavy oil viscosity …

Resins are important molecules for colloidal system (maintaining asphaltenes dispersed) of
heavy oils and are responsible of their high viscosity (together with asphaltenes). The results …

High polar asphaltenes are easy to precipitate and deposit in transportation pipelines and
subsequent processing. Adding chemical polymer inhibitors is an effective method to inhibit …
