Paper: Paraffin Control By Plastic Coating

The accumulation of paraffin in both pumping and flowing wells has been a major problem to the production of crude oil since the very beginning of the petroleum industry. During recent years much progress has been made in methods of removing paraffin from these wells, some of the methods noted are chemical solvents, hot oil treatment, steaming and etc. These methods usually involve wells shut down, lost time, extra labor, special equipment and much expense to the operator. Therefore, the search for a more economical method has been continued and in almost every case plastic coating has been the answer to these problems. In the special cases where plastic will not perform to expectation are pumping wells, due to the abrasive wear from rods, even in these cases plastic will benefit the operator to a certain degree.
