Surface Christmas Tree (Dry Tree) - Duration: 4:32. drillingformulas 67,185 views BHGE Subsea Tree Systems are light-weight and designed for simplified low-cost installation. BHGE has installed over 1,400 subsea tree systems worldwide. Our trees are based on standardized, modular designs that drive high manufacturing consistency and delivery speed. Used on offshore oil and gas fields, a subsea tree monitors and controls the production of a subsea well. Fixed to the wellhead of a completed well, subsea trees can also manage fluids or gas injected into the well. Since the 1950s, subsea trees have been topping underwater wellheads to control flow. An assembly of valves, spools, pressure gauges and chokes fitted to the wellhead of a completed well to control production. Christmas trees are available in a wide range of sizes and configurations, such as low- or high-pressure capacity and single- or multiple-completion capacity. See: choke, frac stack, frac tree, pressure gauge, production tree. Christmas trees are used on both surface and subsea wells (current technical limits are up to around 3000 metres and working temperatures of -50°F to 350°F with a pressure of up to 15,000 psi). The deepest installed subsea tree is in the Gulf of Mexico at approximately 9000 feet. Components of a Subsea Christmas Tree. Typical components of a typical subsea Xmas tree include: Tubing hanger system. A tree connector to attach the tree to the subsea wellhead. The tree body, a heavy forging with production flow paths, designed for pressure containment, annulus flow paths may also be included in the tree body.
Component design is a vital point in the subsea Xmas tree design. based on the information of oil/gas production, reservoir characteristics, production rate, As an important part of the deep-water oil and gas field, the development process of subsea Christmas tree includes design, manufacture and test. The testing

It was named for its resemblance to the series of starting lights at a drag racing strip, called by that name.
13 Jan 2020 Oil and gas unique system for insulation of subsea equipment used in offshore. Christmas trees and metering modules provide the most complex Choke and connection systems are also present on trees to add to the
Christmas trees are used on both surface and subsea wells. It is common to identify the type of tree as 6 Aug 2016 Two type of subsea Christmas tree are vertical Christmas trees and Deepwater Petroleum Exploration & Production: A Nontechnical Guide, Used on offshore oil and gas fields, a subsea tree monitors and controls the called xmas trees because the devices can resemble a tree with decorations. Subsea Xmas tree is the core equipment in offshore oil & gas production system. Installed on subsea wellhead, the tree is used to connect and support tubing 8 Nov 2019 Christmas trees used in offshore drilling and extraction are called subsea trees. Subsea trees can be vertical or horizontal based on how the Our subsea trees are made to safely and effectively endure the toughest conditions on the planet, operating in ultra-deep waters under extreme pressures and
