INHIBITION OF ASPHALTENE

摘要

Methods, systems and compositions reduce or prevent the formation of asphaltene deposits by controlling the precipitation of asphaltene. An asphaltene inhibitor is utilized comprising an aromatic core. The asphaltene inhibitor is introduced into a well or pipeline. The method of utilizing the inhibitor may include the use of a downhole continuous injection process or squeeze treatment. A method of reducing asphaltene scale deposition including adding an asphaltene scale deposition squeeze treatment inhibitor to a hydrocarbon reservoir is provided. The asphaltene scale deposition squeeze treatment inhibitor may be added to the hydrocarbon reservoir by a squeeze treatment process.
