McClain Oil Tools proudly manufactures the highest quality coil tubing parts and expendables to make operations as efficient as possible. These spares and expendables are designed to be replaced at various times throughout the operation. Our role in coiled tubing operationsĭue to the rigorous and often extreme conditions of drilling, various components along the coil tubing process wear out through use. Coil tubing can perform practically any operation for oil well operations whenever utilized accurately. It can also be used to fracture the reservoir, a process where fluid is pressurized to thousands of PSI on a specific point in a well to break the rock apart and allow the flow of product. It is used as a less expensive version of work-over operations and to perform open hole drilling and milling operations. There are numerous advantages to coil tubing: safe and high operating efficiency, fewer personnel needed at the site, easy to cooperate and save cost, smaller environmental footprint and constantly pumping fluids through when running and retrieving the coil.
Although, on platforms with no drilling facilities a self-supporting tower can be used instead. Ī coiled tubing operation is normally performed through the drilling derrick on the oil platform, which is used to support the surface equipment. This offers well control capabilities beyond those normally possible with drill pipe, and gives the ability to drill underbalanced. Pumping can be fairly self-contained, almost a closed system, since the tube is continuous instead of jointed pipe.Īn additional advantage is that the coiled tubing enters the hole via a stripper, mounted on the injector, which provides a hydraulic seal around the coil. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole, rather than relying on gravity. Additionally, it is used for cleanouts and removing filler materials.Ĭoiled tubing is often used to carry out operations similar to wirelining. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Also, coiled tubing does not require a workover rig.Ĭoiled tubing is recognized as a very effective solution for deep wells. Coiled tubing is injected into the existing production string, unwound from the reel and inserted into the well. It is often chosen over conventional straight tubing because conventional tubing has to be screwed together.

The tubing is spooled on a large reel and can be taken inside the borehole to the depth of 20,000+ feet. What is coiled tubing and what is it used for?Ĭoiled tubing is a very long strand of metal pipe made from low carbon alloy steel. One such method of extraction is through coiled tubing operations. Before becoming products like plastics and cosmetics, however, the raw petroleum must be extracted from the ground.
It provides us with many essential petroleum products that are used in our everyday lives. The oil and gas industry is one of the world’s most powerful, profitable and beneficial economic sectors.
