What happens to the Christmas tree when the well is plugged and abandoned?
Xmas tree is removed and replaced by a blowout preventer, through which the production tubing can be removed..
What is the difference between wellhead and Christmas tree?
Wellheads and Christmas trees are different pieces of equipment (Figure 1). A wellhead is used during both drilling and production. During drilling, it is used without a Christmas tree while during production it is used in combination with the Christmas tree, to which the wellhead connects.
What is a subsea Xmas tree?
A subsea Xmas tree is basically a stack of vertical and horizontal valves installed on a subsea wellhead. It is installed provide a controllable interface between the well and production facilities.
What do you add to water to make Christmas tree last longer?
When you get your Christmas tree home, first, boil a gallon of water. Then, dissolve one cup of sugar in the water and allow the mixture to cool. Make a fresh, half-inch cut at the base of the Christmas tree trunk. Position the Christmas tree in a sturdy stand, then pour in the warm sugar water.
What’s the best way to keep a Christmas tree alive?
Learn How to Keep Your Christmas Tree Fresh for the Entire Month of DecemberPut the tree in water as soon as possible. Remember: You’re bringing home a live plant. … Trim the trunk. … Water, water, water (and maybe try additives). … Be cautious of heat sources including lights.
What do you do if your Christmas tree isn’t drinking water?
If you aren’t ready to bring the Christmas tree indoors, place it in a bucket of cool water and store it in a cool, shady place. Storage should be limited to two days. Don’t worry if your tree doesn’t absorb water for a few days; a freshly cut tree often won’t take up water immediately.
What are the parts of a 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.More items…
What is well head pressure?
Wellhead pressure – pressure at the top of the well, i.e., at its wellhead. It is measured by pressure gauges of the wellhead fittings. … Numerically it equals the difference between reservoir pressure and hydrostatic pressure of the liquid column from wellhead to reservoir.
What is Christmas Tree drilling?
1. n. [Drilling] The set of valves, spools and fittings connected to the top of a well to direct and control the flow of formation fluids from the well.
Should you saw bottom of Christmas tree?
If you need to, chop or saw off the bottom off the trunk so that it fits into your tree stand. Avoid putting your real tree in sand or soil as this can reduce the amount of water it can uptake.
What is a wet tree?
Wet tree platforms have a central moonpool for running marine risers, subsea blowout preventers (BOPs) and trees. The marine risers and BOP are heavy and require large deck areas for storage and handling. However, trees are manifolded and shut in at the seabed while the drilling rig is fixed.
What is production tree?
1. n. [Production] A Christmas tree that is installed once fracturing has been completed and the frac tree has been removed. Production trees tend to have smaller bores and lower pressure ratings than those of frac trees, which makes them more economical to use during the less-demanding production phase.
What is Christmas tree wellhead equipment?
A wellhead consists of heads, hangers, spools and a series of seals. Christmas Tree consists of chokes, valves and spools. The main purpose of christmas tree is to control the flow of well fluids or gas during production.
How does a subsea Christmas tree work?
Subsea tree (wet trees) is a system of valves, flow paths, piping, and connectors installed on a subsea wellhead to contain and control the flow of fluid from a reservoir or from the surface by injection. … Two type of subsea Christmas tree are vertical Christmas trees and horizontal Christmas trees.
Should I put an aspirin in my Christmas tree?
A: Do not add molasses, sugar, soft drinks, aspirin or commercial products to the water. Additives provide no real benefit. The keys to keeping a Christmas tree fresh are to place the tree away from any heat sources (fireplace, heater, radiator, etc.) and keep the tree reservoir full of water.
Should I drill holes in my Christmas tree?
Cut straight across, never at an angle or in a V-shape, because doing so reduces the amount of water available to the tree. It also makes it harder for the tree stand to hold the tree. And no matter what Uncle Joe told you, never drill a hole in the base of the trunk thinking it will help the tree draw up more water.
Should I add anything to Christmas tree water?
Make sure your Christmas tree always has enough water. Even though you’ve heard people talk about adding things like bleach, corn syrup, aspirin, and sugar to the water, tree preservatives and additives are probably unnecessary. Most experts agree that plenty of clean water is all you need to keep a tree fresh.
Do you give Christmas trees sugar water?
There is some debate about whether adding any kind of mixture to the water helps keep a tree fresher longer. … However, the study’s author, tree scientist Les Werner, says additives such as sugar, aspirin or even vodka don’t help. “Clean water still works the best.” But don’t take their word for it.
How do you plug and abandon an oil well?
A well is plugged by setting mechanical or cement plugs in the wellbore at specific intervals to prevent fluid flow. The plugging process usually requires a workover rig and cement pumped into the wellbore. The plugging process can take two days to a week, depending on the number of plugs to be set in the well.
What is the purpose of a 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 a wellhead choke used for?
Wellhead chokes are used to limit production rates for regulations, protect surface equipment from slugging, avoid sand problems due to high drawdown, and control flow rate to avoid water or gas coning. Two types of wellhead chokes are used. They are (1) positive (fixed) chokes and (2) adjustable chokes.
