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. Subsea Trees Subsea Production Systems Collection With field development targeting deeper waters and remote areas around the world, locating as many components of the hydrocarbon facilities as possible directly on the seabed seems to be the best economic and practical solution.
Christmas trees and metering modules provide the most complex shape structures that require insulation. The two structures tend to contain numerous electrical and hydraulic line connections which must be accommodated with the insulation design and are also present in Subsea xmas trees larger structural frame. There is no excerpt because this is a protected post. 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 string.
In petroleum and natural gas extraction, a Christmas tree, or" tree"is an assembly of valves, spools, and fittings used for an oil well, gas well, water injection well, water disposal well, gas injection well, condensate well and other types of wells.
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 temperatures.
Horizontal and Vertical X-mas Tree A subsea Xmas tree is basically a stack of valves installed on a subsea wellhead to provide a controllable interface between the well and production facilities. It is composed of a variety of valves, which are used for testing, servicing, regulating, or choking the stream of produced oil, gas, and Aug 29, 2014. The difference between a wellhead and a Christmas tree in the oil and gas industry.
