SUBSEA TREEHorizontalBore™

The Dril-Quip HorizontalBore Tree is used for subsea wells that may require multiple work-over during the life of the well, for wells that have complex downhole electric configurations, and for wells that may require downhole submersible pumps. The horizontal tree offers the flexibility of running and pulling the tubing hanger without disturbing the tree-to-wellhead connection, the flowline connection or the subsea control module to the tree. Dril-Quip HorizontalBore Trees can be equipped with direct hydraulic, electro-hydraulic or fiber optic based multiplex control systems. Vertical or horizontal flowline connections are available, in either hydraulic or mechanical versions. The Dril-Quip HorizontalBore tree is available in 5-1/2” and 7” production tubing sizes and incorporates a 2-1/16” size annulus access.

Dril-Quip’s HorizontalBore™ Tree is a modular design subsea production component that accommodates numerous completion configuration possibilities.

High Fatigue Tree for Long Service LifeThe Horizontal Tree connector is a hydraulic connector with mechanical override. The connector has a secondary mechanical lockdown feature to ensure connection preload is maintained. The tree connector can be provided with a variety of industry standard locking profiles. A secondary unlock piston provides 88% more unlocking force than locking force and is standard.

Adapts to All 3rd Party ComponentsDril-Quip’s HorizontalBore Tree can be configured to accommodate all industry standard subsea wellhead system locking profiles. Multiple interface options are available when integrating components from separate manufacturers. The tree is compatible and available with a variety of manufacturers’ chokes for production and annulus flow. The tree can accomodate all industry standard subsea control systems.

Field Proven PenetratorsDril-Quip’s HorizontalBore™ Tree penetrators utilize an industry standard design that offers dependable long service life. Dril-Quip’s HorizontalBore Tree can accommodate nine hydraulic plus two electrical down hole functions.

Industry Standard Annulus and Production Bore SealsDril-Quip’s tubing hanger annulus and production bore seals are metal-to-metal end cap seals with elastomeric backup design. The seals feature high level extrusion resistance necessary for high pressure/high temperature containment. The seal is weight set and pressure energized.

Availability of Valve Options for a Range of Completion ConfigurationsDril-Quip’s field-proven DH (high performance) gate valve and DA hydraulic actuators are engineered for reliable service in shallow or deepwater applications. They are manufactured from high-grade materials and precision machined for dimensional accuracy and consistent high quality. Dril-Quip gate valves have been equipped with fail-safe close actuators and qualified to 10,000 feet per API 17D, 2nd Edition and API 6A, 20th Edition.

Dril-Quip’s innovative communications system takes advantage of over 15 years of experience using fiber optics in subsea communication applications. Dril-Quip designs and manufacturers modular control systems for a range of applications from a one-off production well through a complex field development incorporating multiple production trees, production manifolds, and distribution manifolds. Dril-Quip’s Subsea Control System can be designed to support all tree and downhole functions for any Horizontal or Vertical Tree Subsea Completion System. These control systems can be direct hydraulic, electro-hydraulic, multiplex or any combination that meets or exceeds customers’ specifications.

cOntrOl system Features:• All components meet or exceed ISO 13628-6 and API 17F standards for functionality, expandability and

reliability. • Subsea Electronics Module (SEM) provides users real-time access to tree functions, tree equipment status

and sensor performance monitoring. • Open architecture using industry standard interfaces allows for control and monitoring of over fifty wells and

the collection of all data within five seconds with fault tolerant redundancy.• Fiber-optic-based communications in applications with over 50 mile offset and demonstrated reliable
