Tree systems are designed from standard “building block” components to meet exacting standards and requirements ranging from less than 100 ft up to 10,000 ft water depths.

Tree configurations include simple diver assist shallow water mudline trees (TOM) up to drill through and deepwater guidelineless horizontal trees (HT) and vertical or conventional trees.

Tree system designs can accommodate reservoir shut in conditions of 350ºF and 15,000psi and in the other extreme provide facilities for electrical or hydraulic submersible pumping systems (ESP / HSP), or artificial lift by gas or water.

VetcoGray’s tree’s are designed to accommodate it’s own range of Choke products which can be configured for production, water or Gas injection (lift) or chemical injection services.

VetcoGray takes pride in providing bespoke or novel solutions for specific field requirements for example:
  • Tree on Mudline for deployment from Jackups.
  • Trawl friendly protection structures, either tree deployed, wellhead deployed, or freestanding.
  • Flowbase for single well or daisy chain / mini manifold.
  • Template applications.
  • Guidelineless trees for deepwater applications.
