production systems over the years has been one of the main problems in the oil industry . Selectedchemical factors controlling the dissolution of the asphaltenes in the specimens recovered from massproduction systems was limited . Currently accepted methods for solving this problem Nzyrgzylnaromatic solvents , toluene and so on . This method requires the use of large amounts of solvents . Thehigh frequency of this procedure should be done . In this paper the results of tests on oil fields andasphaltene control chemicals and laboratory tests to eliminate the use of chemical inhibitors, asphalteneprecipitation and deposition of asphaltenesdescribes. Preliminary tests of power dissipation, theexperiment started spreading asphaltenes in n-hexane . Some chemicals that promising results inasphaltene solubility and dispersion containing insoluble in hexane media have presented , for use inthe oil fields or for additional test samples meet the current ore deposits have been selected.Sets the current test sample (core flow test apparatus) way to become familiar with the study ofasphaltene precipitation and removal using chemical agents is presented .Sfaltynhay obtained from rocksamples and production resources , this gives us theopportunity to select the best chemical treatment ofasphaltene deposition.
