What is the function of Christmas tree?
A Christmas tree is a piece of equipment that provides flow control on a oil or gas well. Christmas trees are a vertical assembly of valves with gauges and chokes that allow for adjustments in flow control as well as injections to stimulate production.
What is the message of Christmas tree?
Symbol of Eternal Life
The legend also has that after the birth of Jesus Christ in the winter season, some of the trees shook off the snow and turned green to mark the great event. Thus, the Christmas tree represents permanence and immortality.

What does a subsea tree do?
Subsea trees are required to control hydrocarbon production. These complex assemblies of valves and other components are installed at the wellhead to monitor and control production flow, and manage gas or fluids injection.
What is a Christmas tree subsea?
A subsea Christmas tree is a pressure-containing barrier between the well and the subsea environment; – It provides control of the produced fluid through a choke valve; –
What are the main components of Christmas tree explain the function of each component?
The basic components of the Christmas tree include the following: PRESSURE GAUGE: Pressure gauges allow well pressures to be monitored. Tubing pressure and casing or annular pressures are monitored with these gauges. GAUGE FLANGE (CAP): Provides a seal for the top of the tree and has provisions for a pressure gauge.
What do Christmas lights represent?
Lights and Candles
May the beautiful lights of every holiday season remind us of Him who is the source of all light.” 1 Christmas lights can remind us that Jesus Christ is the Light of the World. They can also remind us to be lights to others and to help others come unto Christ.

Even though Christmas trees once carried religious connotations, the Supreme Court found that a Christmas tree, by itself, is not a religious symbol. “[T]oday [Christmas trees] typify the secular celebration of Christmas,” the Supreme Court said.
How does a subsea system work?
– The Manifold Module provides the interface between the production pipeline, flowline and well. – Pipelines or flexibles normally interconnect the manifold. – Collecting produced fluids from individual subsea wells. – Distributing production fluids, inject gas, inject chemicals and control fluids.
What is the difference between wellhead and Christmas tree?
Many times, the words Christmas Tree and Wellhead are used interchangeably; however, a wellhead and Christmas tree are entirely separate pieces of equipment. A wellhead must be present in order to utilize a Christmas tree and is used without a Christmas tree during drilling operations.
What are the components of Christmas tree?
Christmas tree includes the following components:
- Tree cap and gauge.
- Tree adapter.
- Swab valve.
- Kill wing valve.
- Production wing valve.
- Surface choke.
- Master Valves (Upper and Lower master valves)
- Tubing head adapter.
How does a subsea Christmas tree work?
The functional requirements of a subsea tree are broadly similar to those of a land or platform tree: It is a vital component in the well integrity barrier envelope. It attaches to the wellhead and directs flow through a series of valves to the flowline. It is used to isolate flow from the well.

Germany is credited with starting the Christmas tree tradition as we now know it in the 16th century when devout Christians brought decorated trees into their homes. Some built Christmas pyramids of wood and decorated them with evergreens and candles if wood was scarce.
What is the subsea processing?
Subsea processing is used to increase the hydrocarbon production in a cost optimized way for new field developments, tie-backs and for existing facilities. It can also enable production in marginal fields.
What is subsea structure?
Subsea structures are underwater constructions installed on the seabed as foundations, support and protection for subsea oil and gas processing equipment as wells, Xmas trees, connection systems, piping and valves.
What is the function of wellhead?
The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment. While drilling the oil well, surface pressure control is provided by a blowout preventer (BOP).

What is the function of swab valve?
The swab valve is yet another manually operated valve which provides direct vertical access to the well for well interventions.
What is the most popular symbol of Christmas?
The star is one of the most recognizable symbols of the holiday. It represents the star that appeared in the sky when Jesus Christ was born.

Why is it called a Xmas tree oil and gas?
Nothing about its rigid metal structure evokes the notion of Christmas, but it was named Christmas tree due to its resemblance to the series of lights at the start of a drag racing strip, which is also called a Christmas tree.
