Using Paraffin Remover to Keep your Wells Clean

Paraffin refers to a waxy buildup of organic materials in oil wells and is one of the most common problems in oil production. Most crude oils contain paraffin crystals and as the oil cools, paraffin crystals form bundles. These bundles are deposited in the well bore, flow lines, pipes and tubing, and if left unattended, they turn into blockages that eventually stop the flow of oil. This problem is easily solved, but if left untreated these deposits can drastically reduce the efficiency of your oil production.

There are several methods for removing paraffin build-up, including:

•    Mechanical
•    Scraping
•    Coiled Tubing
•    Thermal
•    Hot Oiling
•    Hot Water
•    Chemical – Wax Solvents/Dispersants
•    Combination Treatments

Paraffin remover helps keep your wells clean and removes significantly more paraffin/asphaltene than traditional solvents by keeping paraffin suspended in solution longer and inhibits paraffin deposition. Chemical methods are an effective and efficient solution to paraffin removal.

Some paraffin removers require heat to be effective, which is expensive, requiring additional equipment and increased energy usage so it is preferable to find a solvent effective at low temperatures.

In applying chemicals, it is important to follow recommended safety measures. Some paraffin removers require the use of caustic reagents which can be harmful to workers and can potentially damage the equipment. Some of the solvents are toxic and hazardous to human health and the environment. Top priority should be given to using products that are safe for personnel and the environment.
