When any well repair or workover activities are to be undertaken, coiled tubing is a long metal pipe that is surrounded or rolled over a huge reel and carried to the well site. The coiled tube has no joints, implying that it is a single long metal pipe that may be inserted into a borehole to a depth of up to 15000 feet.
The diameter parameters of coiled tubing vary depending on the wellbore diameter. The CT pipe's diameter ranges from 25 to 85 mm, or 1 to 3.5 inches.
As a leading Coiled Tube Manufacturers, Znergy cables produce and manufacture a wide range of stainless steel coil tubes.
Coiled tubing improves the performance of the well and reservoir. Coiled tubing is used in a variety of procedures on the job site, including:
Milling\sDrilling
Fracture of the rock
Sidetracking
Tubing for production
Drilling with a low bottomhole pressure
Cleanup of the wellbore
Kick-off with Nitrogen
Controlling sand
Cementing
Isolation through mechanical means
Perforating and logging tubes
The CT pipe is uncurled from the reel and straightened before being put into the wellbore. These coiled pipes can be used in both onshore and offshore oil wells.
Coiled tubing is one of the most essential pieces of well intervention equipment in the oil and gas industry, having been created in the 1970s. There are various different types and designs of coiled tubing units available in the industry sector; nevertheless, the components of a coiled tubing unit are very similar. Performance capabilities and hydraulic power control systems are the most significant differences.
The main components of a coiled tubing unit are;
Power Pack
Control Cabin
Injector Head
Pressure Control System
Coiled Tubing Reel
Failure of mechanical equipment, changes in production characteristics, clogging, and increases in injection pressure are just a few of the issues that can arise in a producing well and have a detrimental impact on operations, output, and ultimately money earned. These events may occur after a well is put into production, necessitating well modification in order to attain optimal output; this is known as well intervention.
Well intervention solutions are frequently sought at the first sign of a potential problem with a producing well. If these issues are not addressed, the well may eventually stop producing. When selecting how to tackle the production problem, the problem within the well and the economics of the suggested remedy are weighed.
Rig for Work over
In many cases, corrective work entails repairing the well with a work over rig. A work over rig is similar to a drilling rig, except it is smaller and does not require mud pumping or pressure-control devices. A work over rig is used to remove the sucker rod string, pump, or production tubing from the well, as well as to install wire line cleaning and maintenance equipment. It's vital to remember that work over activities require stopping production and limiting reservoir pressure, a procedure known as "killing" the well.
What is the purpose of coiled tubing?
Coiled tubing is a cost- and time-effective solution for well intervention operations. Rather than withdrawing the tubing from the well, like workover rigs do, coiled tubing is placed into the tube against the well's pressure and during production.
Coiled tubing is a continuous length of flexible steel or composite tubing that can be wound on a big reel for transportation. A reel containing coiled tubing, an injector, control console, power supply, and a well-control stack make up the coiled tubing unit. The coiled tubing is placed into the well after being injected into the existing production string and unwound off the reel.
Coiled tubing is preferred over straight tubing because straight tubing requires screwing together. Coiled tubing also eliminates the need for a workover rig. Coiled tubing is a cost-effective option that may be utilised on high-pressure wells since it is introduced into the well while production is still running.
Operations using Coiled Tubing
Coiled tubing can be used for a variety of well intervention operations, all of which are done on a live well. Cleanout and perforation of the wellbore, as well as retrieval and replacement of damaged equipment, are examples.
Furthermore, recent advancements in coiled tubing enable for real-time downhole measurements that can be employed in logging and wellbore treatments. Coiled tubing can also be used for enhanced oil recovery (EOR) techniques like hydraulic and acid fracturing. Additionally, coiled tubing can be used for sand management and cementing activities.
What is the advantage of using coiled tubing in interventions?
CT equipment and techniques have a number of advantages over traditional drilling and workover approaches. Rapid mobilisation and rig-up, fewer employees, a lower environmental footprint, and time savings connected with pipe handling while running in and out of the hole are just a few of the benefits. In deep or high-angle wellbores, such skills are extremely crucial. By permitting continued circulation during well intervention procedures, coiled tubing can help the operator avoid the danger of formation damage that comes with dying a well. These benefits could result in significant cost reductions as compared to traditional drilling or workover approaches.
