What is a wellhead equipment?
A wellhead is an equipment installed at the surface of a completed oil or a gas well that provides a structural and pressure containing interface for the drilling and production equipment. In other words, this object is installed where casings are terminated by hanging the casings using casing hanger and seals.
What is the first component installed on wellhead?
State-of-the-art of drilling It provides annular outlets, as well as supporting the BOP while drilling the remaining stages. Casing head is generally the first component to be installed after the casing has been set.
Which of the following is not wellhead equipment?
Which of the following is not wellhead equipment? Explanation: Packer is not wellhead equipment. Packer is a mean of isolating the annulus from being produced.
What is wellhead system?
Wellhead systems serve as the termination point of casing and tubing strings. As such, these systems control pressure and provide access to the main bore of the casing or tubing or to the annulus.
Which is the topmost equipment in wellhead assembly?
The surface pressure control is provided by a Christmas tree, which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production.
What is the difference between bop and Christmas tree?
Many times, the words Christmas Tree and Wellhead are used interchangeably; however, a wellhead and Christmas tree are entirely separate paces of equipment. A wellhead must be present in order to utilize a Christmas tree and is used without a Christmas tree during drilling operations.
How is wellhead installed?
The wellhead is slipped on to the surface or conductor casing, and the base plate landed on the first casing string run (normally drive-pipe). The welding procedure is then performed which typically includes preheating, welding of the head to casing, postheating, and cooling.
What is wellhead Control Panel?
Performing a safety critical function on manned and unmanned platforms, our Wellhead Control Panels (WHCPs) are designed for monitoring, controlling and shutdown of various subsurface and surface valves.
What is the name for the well head and valve assembly used to control a well?
The system of spools, adapters, and valves to control the pressure of a well in drilling and production operation is known as Wellhead Equipment.
What is the function of wing valve in wellhead?
A wing valve is a piece of flow-control equipment used in oil and gas operations. It is part of a Christmas tree and used to shut in flow from a producing well.
What is the difference between a 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 kind of equipment does a wellhead use?
This includes specialized materials for sour service and CO2, corrosion resistant alloys (CRA), water flood, multiple completions, coiled tubing and instrumentation lines, and multi-bowl equipment.
Which is the Top Spool on a wellhead?
The Tubing Head is the top spool on a surface wellhead. It is typically installed over the last string of pipe suspended in the well, the production casing. These heads come in a wider range of types and sizes than any other head in a conventional wellhead system.
What kind of wellhead equipment does rein make?
REIN WE designs, fabricates, and supplies wide variety of equipment, such as wellhead assembly, Christmas tree, blowout preventers, choke manifolds, kill manifolds, wellhead desander, plug catchers, high-pressure API 6A valves, emergency shutdown valves and ESD system, high-pressure pipe & fittings.
What is the working pressure of a wellhead?
Working pressures range from 2,000 to 20,000 psi and are designed for single or multiple completions. A significant inventory of conventional wellhead equipment is kept in inventory to reduce lead times.
