Pipe coiling has grown in importance within the past five years due to the expansion of fracking throughout North America. Many estimates state that about 50% of the coiled piping in the world was consumed by the United States. Besides fracking, there are many different uses for coiled tubing.
It is very common for a well to experience problems that will severely affect its ability to produce. In order to restore the efficiency of the well, intervention methods are used. One of the most effective interventions is to install coiled tubing. The original pipe, which has not undergone pipe coiling, will not be removed. Rather, the new coiled pipes are installed along the wall of the well, around the other pipes. This is extremely helpful because it allows production to continue at all times, restores the efficacy of the well, and minimizes the time that workers need to be diverted to the process of tube installation.
Another very common use for coiled tubing is as a replacement of the standard 12 meter length of straight pipe that is often used to transport oil or other natural substances from the drilling location to a storage location. Oil companies are switching to tube that has undergone pipe coiling in order to reduce the amount of time it takes to install the tube, because coiled tubing will require less welding that straight pipe. Because the time it takes to install the tubing is reduced, the cost of the installation will also be reduced. Coiled tubing is also better at maintaining the protective properties of any coatings that are applied. Finally, this type of tubing is being used whenever environmental impact needs to be minimized.
Part of a Production String
There are some wells that tend to be shallow that will produce a small amount of water, as well as petroleum. When this is the case, coiled tubing will be installed in straight piping because it increases the velocity of the liquid. This is because the coiled tubing will have a smaller diameter than regular piping. When the petroleum and water mixture increases its velocity, liquids that might hurt the well are forced to the top of the tube and then out where they can be dispersed by the use of a hydraulic or electric pump. This maintains the efficiency of the well and keeps it from breaking down.
Even though coiled piping is heavily used in fracking, it also has a number of other helpful applications that allow drilling and rigging companies to get the job done.
