Coil Tubing
Coiled tubing is a long pipe that can be rolled up and is elastic and made of steel. Coil tubing has an outside diameter of about 1 inch to 3 inches and has a length of approximately 15,000 feet.
DLN’s coiled tubing units (CTUs) are named according to the pulling load rating Hydra Rig (HR) of the injector head. These are made in a range of different sizes to suit different applications. Most new units are available as a standard option or as a certified package for operating in hazardous environments such as offshore/onshore. The main requirements for a certified unit is it’s ability to work in hazardous environments with flammable gasses present and specially certified lifting equipment. This means all electrical components are sealed to prevent possible ignition sources and major modifications are required to the diesel power pack to prevent ignition sources from sparks, etc.
ADVANTAGES
1. Efficiency
a. Self-Contained unit, requires no rig
b. Saves time and money – do not have to kill well
2. Reduced potential damage to formation
a. Typically used on live wells so no kill fluids necessary
b. Act as tool transport medium for deviated & horizontal wells
3. Performance
a. Computer programs to optimize job design
b. Fast
c. Utilize internal pressure to generate large downhole forces
4. Tubing Management
Advanced data acquisition system to monitor key job parameters – on tubin management.
PHYSICAL CHARACTERISTICS
- Self Contained
- Mobile/Modular
- Hydraulically Powered
- Environmentally Friendly
OPERATIONS
- Injects and retrieves a continuous string of tubing into the well
- Can continuously pump fluids into well while moving pipe
- Land or offshore system designs
- No work over rig required when using CT
- Can be and is typically used on live wells (no kill fluids introduced into well)
COMPONENTS
- Tubing /Pipe
- Injector & Tubing Guide
- Work Reel for Tubing Storage
- Control House
- Power Pack
- Well Control Equipment
- Crane
OPERATIONS
- Steel tubing with several yield strengths available
- Relatively thin wall
- Yield stress is exceeded with each cycle (reel/tubing guide/injector is 3 bending events)
- Finite life due to these fatigue cycles
- Small flow area (1” OD to 3.5” OD max)
- Cannot rotate pipe
- Life dependant on pressure, cycles, axial forces, torques, corrosion, and other well
- Related conditions
