#CoiledTubingOperations. ● Coiled tubing is a technique used in the oil and gas industry for well intervention and production activities. ● It involves the use of a long, continuous metal tube that is coiled onto a reel and then deployed into a wellbore. ● Coiled tubing operations can include activities such as well cleaning, acid stimulation, hydraulic fracturing, nitrogen kickbacks, and even drilling. ●The coiled tubing is typically inserted into the well through the production tubing or casing and can reach considerable depths. It is often used in situations where conventional methods, such not cost-effective. Coiled without the need to repeatedly insert and retrieve tools from the well. ● The coiled tubing itself can be made from various materials, including steel or composite materials, depending on the specific requirements of the operation. It is usually flexible and can be spooled onto a large reel for transport. ● Overall, coiled tubing plays a crucial role in various aspects of the oil and gas industry, providing a versatile and efficient method for well intervention and production activities. ■Factors affecting fatigue life For Coiled Tubing: 1-size of bending radius:A large gooseneck causes less string fatigue than a smaller gooseneck. 2-internal pressure : The pressure inside a CT string while spooling from a reel and over the gooseneck increases the amount of fatigue a CT string experiences greatly. Cycling the CT string at the same point at high pressure over the gooseneck must be avoided because it will result in high CT fatigue. 3-size of CT: Larger sizes of CT string becomes more fatigued than smaller sizes if bent over the same gooseneck. For this reason, larger goosenecks are used with larger sizes of CT string. 4-wall thickness: A low wall thickness section of CT string fatigues more quickly than a high wall thickness section. 5-welds: Welds in a string will fail from fatigue before the tubing itself will. 6- Proper Spooling : Bad spooling when you receive new reel will effect the coil Life. The most important damage mechanism affecting CT is fatigue caused by bending and pressure. #Oilfield #Operations #WellIntervention #ProductionTubing #healthandsafety #petroleumengineering

Coiled Tubing Complete Guide | #drilling_manual Coiled Tubing (CT) is a continuous length of small-diameter pipe that is spooled onto a reel in the same way as wire or cable is wrapped on a drum. The coiled tubing operation permits the technique of "snubbing" a continuous length of tubing in and out of a live well through a stripper BOP arrangement. The main advantage of Coiled Tubing is that it can be run into producing wells, against high wellhead pressures (e.g. 345 bar / 34,500 kPa or 5000 psi), and down past the perforations, without production interruption or killing the well (Wait and Weight - Driller's Method)......

Blowout preventer or BOP stack✨ is the tool in the petroleum industry to prevent such a horrible event like blowout to occur. It consists of several large valves stacked on top of each other. Rigs usually have two type of BOP stack. ✨The one on the top is an annular preventer, ✨and below the annular preventer are ram preventers. Annular preventers or spherical preventer 🤍are able to seal around several size of drill pipe, drill collar, work string, wireline, tubing, etc. The annulaer preventer caonsists of a body, a cap, a piston and rubber packing element. There are four types of ram BOPs. Pipe Ram 🤍💜 It is designed to hold pressure from the bottom only by closing around the drill string or tubular in order to restrict the flow. Variable Bore Ram (VBR)🤍💜 It is similar to the pipe rams but it is able to utilize with a wider range of outside diameter of pipe. Blind Ram🤍💜 This rams are used to close the well bore when there is no drilling string in the wellbore, because they are not able to cut the pipe. Blind Shear Ram🤍💜 It is similar to the blind ram, but it can cut the pipe prior to shutting the well.

It applies a closing pressure to shut off the open hole. It also maintains the seal when the tubing, casing, or drill pipes are out of the drill hole. B_ ram BOP : Besides sealing off the wellbore, the rams can also hang off the drill string. Here are the four different types of ram BOPs. 1_ Pipe Rams: Their sealing elements can fit around various tubular, including the production tubing, drill collars, drill pipes, and casing to seal off the wellbore. 2_ Blind Rams:help seal the wellbore when it has nothing in it. 3_ Shearing Blind Rams: They have blades that cut or shear the drill pipe, followed by sealing 4_ Variable Bore Rams: allow the sealing around a vast range of pipe sizes. #_wellservice #_drillingcomponents #_bop #_ramspreventers #_secondarywellcontrol Halliburton Baker Hughes Schlumberger Oil Field Svcs SLB Rashpetco (Shell-JV)

COILED TUBING UNIT Features The limitations on coiled tubing length are influenced by factors such as tubing diameter, material strength, and the equipment used. Generally, coiled tubing lengths range from a few thousand to around 30,000 feet. Longer lengths may pose challenges in terms of managing weight, pressure drop, and the risk of tubing fatigue. The specific limitations depend on the application and the capabilities of the coiled tubing unit being used.  Perform downhole intervention under pressure using continuous tubing  Has circulation capability (continuous circulation during running and pulling CT string)  Able to perform milling or drilling by attaching downhole motor on the bottom hole assembly  Able to work on horizontal section of a well  Higher pulling capacity than braided line Main equipment  Power pack  Wellhead adapter  Flow tee  Pressure Control Equipment  Combi BOP  Quad BOP  Stuffing box  Injector head and goose neck  Coiled tubing reel  Control cabin Main job  Pumping nitrogen  Milling  Cementing  Sediment washing  PLT in horizontal well It is not allowed to use hydrocarbon gas inside coiled

Coiled Tubing Blowout Preventer Hydraulic Quad Ram BOP It is a well control equipment in the process of coiled tubing operation. Its function is to quickly close the ram by hydraulic pressure to control wellhead pressure and prevent blowout. Main functions: ØWhen there is no coiled tubing in the well, the well can be sealed with blind ram. ØWhen coiled tubing is operating in the well, abnormal well pressure and other special circumstances occur, and when the tubing needs to be cut, the tubing can be cut with shear ram, and at the same time, the well is sealed with blind ram, and the manifold connected by the side flange is pumped into the liquid kill well. ØWhen the coiled tubing is operating in a well, the tubing needs to be suspended, and the coiled tubing can be suspended with corresponding slips. ØWhen the coiled tubing is operating in the well, the well can be sealed with pipe ram of the corresponding specification.
