The difficulty of producing asphalt and paraffin materials is a problem that some oilfields in the world arefacing it. Many efforts and studies have been conducted in order to resolve it, but it should be noted that,the methods of removing it differ with each other from one reservoir to another reservoir and even fromone well to another well in a reservoir. However, various measures should be studied by fulfillingrequired tests and with considering economic parameters, optimal method should be selected in order toresolve deposits and precipitations of these materials.Today, the advanced managements of producing materials from reservoirs always consider side costssuch as thermal energy needed for producing materials from these types of reservoirs. Since some ofIran’s oilfields are facing this problem with different weaknesses and intensity, this study has beenconducted with the aim of studying specifications of these materials, methods of resolving productionproblems and adopting strategies for wells of one of Iran’s southern oilfields which faces this problem.
