Sedimentation of paraffin in the perforation hole and rock formation causes the influx or liquid flow to decrease, causing a decrease in production. If it happens for a long time, it will cause damage to the formation which results in a continuous decline in production until plugging occurs on an oil well. In the production pipeline, paraffin deposits can also cause delays in transferring oil. Consequently, operations could stop. There are several methods for removing paraffin deposits namely mechanical, thermal, or chemical treatments. Chemical treatment, to be specific, is a method to remove paraffin by injecting chemical (paraffin solvent).
Paraffin solvent is a chemical for dissolving paraffin deposits in production wells that have a high aromatic content. Paraffin deposits will dissolve and mix with the oil produced. Soaking The application of paraffin solvent is done by soaking the solvent in the production well for one month. After the treatment, the wells can produce again. To apply this solvent in the production pipeline, apply the chemical by using soaking method before recirculating the production pipe.
