Enhanced Horizontal Subsea Trees (EHXT)
FMC offers 5" x 2" Enhanced Horizontal Subsea Trees (EHXT) in 10,000 psi and 15,000 psi pressure ratings, in standard and drill-through configurations. All EHXT trees are rated for up to 10,000 foot water depth.
FMC EHXT Advantages:
• Traditional pressure-containing internal tree cap has been eliminated, and its pressure containing barriers have been moved to the tubing hanger enabling the tree cap to be installed by ROV off the drilling rig's critical path, after the BOP has been disconnected from the tree.
• The most cost-effective and reliable horizontal completion system available in the industry today.
• Reduction in installation times by two days (or more) with the elimination of the internal tree cap installation via the landing string.
• Reduction in installed CAPEX and increase in safety by only running the subsea test tree system once.
FMC EHXT Features:
• 5" x 2" 15K, 5" x 2" 10K and 7" x 2" 5K designs. The 10K and 5K systems can suspend 7" tubing strings.
• Elimination of the traditional pressure containing internal tree cap.
• The drill-through system allows a 13-3/8" casing hanger to be installed and retrieved through the tree, thereby facilitating the drilling of wells where "light architecture" casing programs can be utilized.
• Simplifies the interface with the SSTT and BOP stack by requiring only one stack-up mode (SSTT only used for TH installation).
• 18-3/4" hydraulic set enhanced horizontal tubing hanger system that incorporates both upper and lower wireline plugs.
Subsea operators have confidently selected the EHXT subsea tree for more than 150 well completions around the globe. The EHXT's tree's modular, standardized design allow customized configurations to be readily produced for a wide variety of project-specific applications. The 10,000 psi EHXT tree system is installed in the latest world record water depth of over 9,356 feet.
