Facts To Know About Paraffin Removal

By Mary Williams


In the oil extraction industry, paraffin wax build-up is a familiar issue. Paraffin wax has a lot of crippling effects on the oil well production. They cause a lot of oil to precipitate, which over time, reduces the oil flow. With time, oil production might stop completely. Oil is among one of the most important natural resources on earth. Thus paraffin removal is important whenever it occurs.

The process of mining oil is done by drilling the earth surface, creating wells. The wells are made in a manner that they are able to drain oil onto the surface. Natural gas can be brought to the surface together with oil. However, the wells for draining natural gas may be dug alone too. A lot of research is done in order to identify the proper location of the wells.

The process is usually done by geologists. The location is chosen to optimize oil production. It is also chosen to confirm any existence of hydrocarbon. The point of injection is also to be determined. This point should be permeable to enable disposing of water or gas. A target is an end point of the well where the oil or gas can be disposed from.

Drilling work can start only after the location is identified. Required size determines the size of the well. Sections of steel that are smaller than oil wells a are inserted into the well during drilling. Safety measures are taken to ensure that workers and equipment are safe. One of the safety measures that is taken involves casting cement into the casing.

Casting the cement provides the well with proper structural integrity. It also helps in reducing the dangers of high pressure regions. Among the heavy organics of crude oil is paraffin wax. They are normally the mixture of asphaltenes and paraffin. Remains of kerosene are composed of salt crystals, sand, gum, resins and silt. It is because of all these deposits that kerosene needs to be removed continuously and constantly from the wells.

Various methods exist to be used for removal of kerosene. It is important for one to consider safety when choosing a method for paraffin elimination. Many methods such as the use of chemical solvents require the use of caustic reagents. Caustic reagents can be very hazardous to workers working in the oil sites. They can also cause damage of oil drilling equipment. Also many chemicals contain toxins that can be harmful to the health of human beings.

There are a range of techniques for eliminating the wax build ups. These methods include, Mechanical methods, scraping method, coiled tubing, thermal method, hot oiling, hot water, and chemical and wax solvents. There are cases when several of these methods are used in combination.

One is advised to keep in mind the nature of the wax build up before choosing any of these methods. This is because the wells that have same problems may have fouling wells. Therefore, it is vital to carry some research on the nature of a build-up and the extend it is. That helps to identify if there are other problems.
