Coiled tubing

Coiled tubing is a continuous, flexible metal pipe used in various well intervention and completion operations in oil and gas wells. This versatile technology allows for efficient interventions without requiring the well to be shut down.

Key Applications:

• Well Intervention: Coiled tubing is deployed through the wellhead for cleanouts, stimulation (acidizing, hydraulic fracturing), sand control, logging, perforating, and even drilling. It enables continuous operation while maintaining well integrity.
• Pressure Control: Critical to safe operations, pressure is managed using blowout preventers (BOPs) to prevent uncontrolled fluid flow.
• Fluid Injection & Circulation: Fluids such as nitrogen, water, or chemicals are injected through the tubing to perform tasks like cleanouts, fracturing, or powering downhole tools.
• Monitoring & Control: Advanced units feature real-time monitoring, allowing operators to adjust operations based on downhole conditions.

Advantages:

• Efficiency: Reduced rig-up time, smaller operational footprint, and the ability to perform interventions on live wells.
• Versatility: Suited for a wide range of applications, from simple cleanouts to complex stimulation treatments.

Specialized Operations:

• Coiled Tubing Cleanout: Removes debris, scale, or sand from the wellbore to restore productivity and improve flow rates. This process involves fluid injection, tool deployment, and real-time monitoring to ensure effective results.
• Nitrogen Lifting: Enhances production by injecting nitrogen into the wellbore, lifting fluids to the surface, and optimizing flow in wells with low reservoir pressure.
• Concentric Coiled Tubing: Features dual tubing for simultaneous fluid injection and production, offering enhanced performance and operational efficiency in complex well conditions.

Coiled tubing is essential for maintaining and optimizing production in oil, gas, and geothermal wells, providing a reliable solution for a wide range of well intervention and completion activities.
