Coiled tubing technology has revolutionized various operations in the oil and gas industry. This paper provides an overview of the applications, advantages, and limitations of coiled tubing technology. Starting with its historical development and basic components, the paper delves into the diverse applications of coiled tubing, including horizontal drilling, hydraulic fracturing, well cleanout, acid stimulation, and rigless completions. The advantages of coiled tubing, such as its ability to operate in pressurized or producing wells, quick deployment, and suitability for horizontal or deviated wells, are highlighted. The importance of coiled tubing cycles and fatigue analysis is discussed in detail to ensure safe and effective operations. The downhole equipment used in conjunction with coiled tubing is also explored, covering connectors, release joints, centralizers, nozzles, impact tools, under reamers, retrieving tools, check valves, and packers/plugs. Furthermore, the paper addresses the dimensions and specifications of coiled tubing, emphasizing its versatility and customization potential for various projects. It showcases the significance of coiled tubing in rigless deep-water applications and its role in cost-effective well intervention, drilling, completion, and well maintenance operations. Despite its numerous benefits, the paper acknowledges the limitations and challenges associated with coiled tubing technology, including safety considerations, costs, and equipment limitations. The conclusion highlights the ongoing efforts to improve coiled tubing technology, making it a valuable and indispensable tool in the oil and gas industry's future endeavors.
