Christmas Tree Oil And Gas Function
The primary function of a tree is to control the flow usually oil or gas out of the well.
Christmas tree oil and gas function. Christmas tree valves are an integral part of oil and gas wells. A tree often provides numerous additional functions including chemical injection points well intervention means pressure relief means such as annulus vent well monitoring points such as pressure temperature corrosion erosion sand detection flow rate flow composition valve and choke position feedback connection points for devices such as downhole pressure and temperature transducer. Choke frac stack frac tree pressure gauge production tree.
It provides a means of controlling the effluents ensuring the safety of the facilities and giving measurement tools access to the well. It is named for its resemblance to a decorated tree at christmas. It used for production or injection wells such as oil wells gas wells water injection wells water disposal wells etc.
A tree may also be used to control the injection of gas or water into a non producing well in order to enhance production rates of oil from other wells when the well and facilities are ready to produce and receive oil or gas tree valves are opened. Normally the flow out is oil and gas and flow in is gas for gas lift. Well completions 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.
Its show how gas lift works. It is a separate piece of hardware that connects to the wellhead after the. Wellhead and christmas tree is the main equipment for oil production water injection and downhole operation.
Below is a list of wells that implement christmas tree valves but know these systems are more useful beyond this small range of applications. What are the functions of christmas trees in oil and gas installations. A christmas 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.
In the oil gas industry a christmas tree is a piece of heavy equipment that controls the flow produced by a well. The well has at least one pipe inside pipe and the resulting annular space. It is installed on the casing head to seal the annular space between casing and tubing control wellhead pressure adjust well flow rate and transport oil to pipeline.
