- A set of techniques used to prevent or considerably reduce paraffin deposition. Paraffin control might involve the following options:Â· use of paraffin inhibitors.Â· maintaining pipe surfaces in a water-wet condition because paraffin will not adhere to water. However, the presence of natural surfactants in some crude oils converts water-wet surfaces to an oil-wet condition, making this technique effective only temporarily.Â· coating the pipe with plastic to provide a smooth surface and reduce paraffin adhesion.Â· reducing heat transfer to maintain the oil temperature above its cloud point. Filling the annulus of a well with a fluid that has poorer heat transfer properties than the oil maintains the temperature of the flowing crude oil above its cloud point.
