One major problem of working in the oil sector is having to deal with recurring problems pertaining elimination of unwanted deposits. Paraffin will slowly start to build up in your systems contrary to what you may expect. It is not a question of if the buildup will occur, but when it will start to buildup. Data obtained from various sources indicate that eighty five percent of the oil available in the world today is susceptible to asphaltene buildup. As it continues to build up, it will start to make it more difficult for your people to drill the oil. If wax and asphaltene removal is not done early, there may be various inconveniences and thus the need to ensure deposit eliminations are done.

Based on the various statistics, it is clear that paraffin deposits can cause a major problem in oil production areas. With time, the deposits reduce the flow of oil to a point where it no longer becomes tenable to continue with the production processes. Failure to treat this buildup immediately will drastically reduce the effectiveness of the oil transfer and recovery system.

As such, there is a need to ensure that the buildup is eliminated as often as possible. Its elimination will require you to have the oil transfer system and the accompanying recovery system given a thorough checkup. When combined, the entire system comprises of the oil being transferred through flow lines, pipes, and the tubing. You do not have to worry about the deposits crippling your operations as you can easily remove them.

Removal of unwanted deposits calls for one to possess latest information on the industry accepted techniques and processes. At the moment, there are numerous methods already in use in oil production areas. They include thermal, mechanical, hot oiling, chemical, hot water, scraping, combination treatments, and coiled tubing. Each method is effective in its own unique way, but you will need to learn how it works before implementing it.

Paraffin wax is the general term used to refer to all deposits encountered when investigating any oil buildup. But the reality is that, paraffin is not the only deposit you will find. Silt crystals, gums, and clay are other deposits that are commonly found and require elimination.

In many cases, any heavy organic deposit that you come across when extracting oil will automatically be referred to as wax or paraffin. Even though paraffin tends to be the major component in all the deposits, you will normally end up with a blend of asphaltene and paraffin. The deposits are unique in that they contain clay, resins, sand, silt, scale, gums, and salt crystals.

As you continue to drill for oil. The buildup, though slow, can negatively impact future production processes, when it becomes too much. A time will come when the paraffin wax will completely cripple all your processes. Therefore, regular cleaning is ideal to remove all residuals.

Ensure that you also consider the safety of the people who will deal with the elimination of such deposits. Some chemicals will require you to apply a caustic reagent. Such a solution should be avoided as the reagent can pose a health hazard to your personnel as well as to the oil drilling equipment that they are trying to clean.
