Horizontal Tree Wellhead

Main design features Reduced wellhead height Wellhead capability to accept both a "heavy" casing program or a "light" casing program Large sized Tubing Hanger add flexibility to completion design Tree installation/removal is not required for work over operations Security/safety during work over operations is improved as handling of heavy tree is avoided. BOP installation and test operations are performed without separating the tree Work over operational time is reduced Wells gathered in clusters make positioning of drilling and work over rigs easier and quicker Work over rig operation on a well while other wells are producing The entire wellhead/horizontal tree can be installed below ground level, thus enabling to reduce environmental impact Simplified layouts for manifold and pipelines reduce fixed costs. Sizes: 13.5/8" through 20.3/4" Working pressure: up to 69MPa (10000psi) Temperature range -29°C +121°C (-20°F +250°F) Secondary seals: "GS", "P", "GSP" Top Connection: Quick Lock, Flanged Hub, Flanged Tubing Hangers: Single or Double Completion
