A Novel Method for Mitigation of Asphaltene Deposition in the Wellstring [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2010 Asphaltene precipitation and deposition is a serious problem in many Iranian fields. The deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil production.
