Encapsulated Hydraulic Control Line

Short Description:

Control lines have undergone extensive development, including crush testing and high-pressure autoclave well simulation. Laboratory crush tests have demonstrated the increased loading under which encapsulated tubing can maintain functional integrity, particularly where wire-strand “bumper wires” are used.

Product Introduction

Control lines have undergone extensive development, including crush testing and high-pressure autoclave well simulation. Laboratory crush tests have demonstrated the increased loading under which encapsulated tubing can maintain functional integrity, particularly where wire-strand “bumper wires” are used.

Applications

- Intelligent wells requiring the functionality and reservoir management benefits of remote flow-control devices because of the costs or risks of interventions or an inability to support the surface infrastructure required in a remote location

- Land, platform, or subsea environments

Features, Advantages and Benefits

- Control lines are delivered in orbital-weld-free lengths up to 40,000 ft (12,192 m) to maximize reliability.

- A wide range of single, dual, or triple flat-packs is available. Flat-packs can be combined with downhole electrical cables and/or bumper wires for easier operation and handling during deployment.

- Welded-and-plug-drawn production method ensures a smooth, round tube to allow long-term metal sealing of terminations.

- Encapsulation materials are selected to suit well conditions, ensuring longevity and reliability.

Alloy Feature

Incoloy alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
