Wax And Asphaltene Removal Processes

By Joseph Johnson


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.

The transfer comprises of tubing, pipes, flow lines, and of course the oil that is under production. As mentioned, the buildup can become serious to a point where production no longer takes place due to a breakdown of the system used to recover the oil. The good news, however, is that you do not have to worry about the buildup as it can easily get removed.

All you need to do is learn the methods that are used in removing the unwanted deposits. Currently, there are various methods in existence which can help with this particular problem. You can use combination treatments, mechanical, chemical, scraping, coiled tubing, hot water, hot oiling, or thermal methods to get rid of your unwanted deposits. All these are valid methods which have already been tried and tested in various areas.

As it stands, many industries prefer to use chemical solvents to clean up. However, chemicals do pose a challenge in that you cannot start using chemical solutions before you have an idea of the kind of deposits that are present. A closer look at your wells may reveal that you are dealing with much more than a deposit problem as there could be an underlying issue as well.

As stated earlier, different techniques are applied in the cleaning process. You are advised to take some time to consider the problem at hand before settling on the most efficient chemical solution. Make sure that it can get rid of as many deposits as possible. If no solution can do this for you, then combine two or three methods to guarantee that the issue will not recur soon.

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.

Safety is the final consideration when determining which chemical to use in eliminating the deposits. Some chemical treatments will require you to use caustic reagents. The reagents are effective, but they pose a danger to the equipment and to the safety of the personnel working on the system.
