Wellheads and Christmas trees: Is there a difference?

Q: I work as an instrumentation design engineer on an offshore platform and have some questions. What is the basis of this requirement? Why should all valves close within 45 sec? What would happen if they did not? We have a noise level limit of 85 dBA for these valves. Is that limit for the noise level up- or downstream of the valves? What is the straight-run requirement for these valves, and does that relate to the noise limit?

In the complicated but vital industry of drawing oil and gas out of the earth and getting it to the surface, people often get confused about the difference between a Christmas tree assembly and a wellhead. Although the terms are used interchangeably, they are not the same piece of equipment. Each has valves and related equipment that help it control and guide the flow of this precious resource. A Christmas tree is an assembly of valves, spools and fittings used for oil, gas, water injection, water disposal, gas injection, condensate and other types of wells. It is named for its resemblance to a decorated tree at Christmas. A wellhead must be present to utilize a Christmas tree and is used without a Christmas tree during drilling operations. The wellhead is the component at the surface of a well that provides the structural and pressure-containing interface for the drilling and production equipment.

A Christmas Tree comprises a series of valves, spools, a choke, and connection. It used for production or injection wells such as oil wells, gas wells, water injection wells, water disposal wells, etc. A wellhead must be present in order to utilize a Christmas tree and is used without a Christmas tree during drilling operations. Producing wells that require pumps, such as Sucher Rod Pumping Systems, frequently do not utilize any tree due to no pressure containment requirement.
