Significant operating costs are incurred from treatments designed to remove waxy deposits from production tubing or squeeze treatments designed to inhibit wax deposition. The costs are further increased by formation damage and loss of production that may result from these treatments. Studies show that paraffin deposition can be prevented or greatly retarded by using chemical surfactants known as dispersants. Two specific surfactants were selected that proved to be very effective paraffin dispersants. One is oil soluble and the other is water soluble. These dispersants can be continuously injected into the well or they can be added in larger quantities in a ''batch treatment'' at specific time intervals. The choice of whether to use batch or continuous treatment is governed by the type and number of wells requiring treatment.
