Flexible, fit-for-purpose design

The X-11™ modular offshore CT unit was developed as a flexible, fit-for-purpose system that is easily adaptable for many offshore structures including platforms, barges, spars, floaters, and tension-leg platforms.

The unit works with CT sizes ranging from 1¼ in to 2⅞ in, and changing from one CT size to another is safer, easier, and more efficient.

  • Offshore applications
  • Adaptable for platforms, barges, spars, floaters, and tension-leg platforms
  • Operates with fly-by-wire controls from the control cabin to all the major skids
  • Provides finite control of injector speed and applied forces
  • Uses computer-controlled systems that eliminate overpull and oversnub scenarios
  • Incorporates automatic hydraulic power pump management system
  • Can be configured to run up to Category III well-control working pressures
  • Offers automatic reel-brake fail-safe system
  • Reduces the need for personnel to climb on top of the injector through the use of a semiautomated tubing stabbing process
  • Monitors the condition of all the electronic, hydraulic, and pneumatic systems
  • Works with CT sizes from 1¼ in to 2⅞ in
  • Offers fail-safe systems that incorporate complete manual backup
  • Enables detailed, accurate entry into the wellbore through real-time geometry inputs
  • Provides constant monitoring of BOP system pressures and valve positions
  • Reduces the number of hydraulic and mechanical connections required to set up
  • Offers zoned, ATEX, and CE-marked certified control cabin, hydraulic powerpack, reel, and injector

Active process control and automated safety systems for all offshore applications

The X-11 unit comprises five main skids:

  • a hydraulic power pack
  • a control cabin
  • a drop-in drum reel
  • two transport baskets that contain well-control equipment and the injector.

Modular in design, the hydraulic power pack, the control cabin, and the transport baskets are built in standard shipping containers, and the control cabin can stack on top of the hydraulic power pack. This design reduces the total weight and footprint of the entire CT system.

The unit’s automated control system monitors well parameters and the entire electric hydraulic system. This control system detects and provides timely notification to the supervisor when changes occur. In addition to providing real-time data acquisition and data transfer to offsite locations, the X-11 unit provides one central control point for the entire CT operation.

The modular package combines major CT components that are easy to connect, that optimize space utilization, and that provide maximum versatility.

Improved safety and efficiency. Less complexity.

The X-11 unit improves the efficiency and safety of the wellsite delivery process, while reducing the cost of the total system. Automating several key processes also reduces the number of operating personnel who are normally required. Improved crew ergonomics, a smaller footprint, and the automated monitoring and control systems allow the CT supervisor to focus on downhole job requirements rather than equipment coordination.
