Wellhead platform generally is a type of oil platform that houses personnel and machineries to extract oil and natural gas through wells in the ocean bed. A wellhead platform (WHP) may include an integrated deck, utility systems, wellhead systems, helideck and drilling facilities.

What is wellhead tower?

The wellhead tower facilities in Offshore are designed to receive well fluid from different oil fields and transport through pipelines for further processing. The functional requirements for any typical wellhead tower do not vary much; leading to similar design features in most of the Offshore facilities.

What is unmanned wellhead platform?

The UWP is a simple structure without helideck or overnight accommodation. It provides easy access to wells, since the wellheads are placed dry on the topside. That contrasts with a subsea development, where the wellheads stand wet on the seabed.

What are the types of wellhead?

• Land.
• Surface locations offshore (jackup or platform)
• Subsea.

What are the components of a wellhead?

Generally, the wellhead consists of three components: (1) the casing head, (2) the tubing head, and (3) the Christmas tree. The casing head consists of heavy fittings that provide a seal between the casing and the surface.

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.

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.

How much does a wellhead cost?

The average wellhead price of crude oil increased $3.58 to $65.23 in September 2021 from August 2021. The monthly average price was $31.82 higher than the average price of $33.41 in the same month last year.

What is wellhead equipment?

The wellhead equipment is the component at the surface of an oil or gas well, which offers the pressure-containing and structural interface for the drilling equipment. It provides pressure seals and suspension point for the casing strings. … The wellheads are welded onto the string of casing, during drilling operations.

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 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 is the wellhead 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 the difference between blowout preventer and Christmas tree?

The Christmas tree sits atop the wellhead, but it is a separate piece of equipment. … Instead a blowout prevention device sits atop the wellhead as the well is drilled and casing/tubing strings are inserted. When the well is moved to production, the Christmas tree is affixed for flow control.

Where is wellhead located?

Locate the wellhead in your yard. This is the top of your well. There should be cap or seal on the top of the casing (pipe) that should extend at least twelve inches above the ground to keep contaminants from entering the system. Soil should slope away from the wellhead so surface water doesn’t puddle.

What is SSV valve?

Surface safety valve (SSV) is a hydraulically actuated fail-safe gate valvefor producing or testing oil and gas wells with high flow rates, high pressures, or the presence of H2S.

What is choke in oil and gas?

Most oil and gas production facilities use a device known as a choke to control the flow of fluids produced from wells. Typically, equipment such as the line heaters and wellsite separators contain a choke. It has a small opening called a choke bean, which helps to reduce the pressure as the liquids flow through it.

What is the lifespan of a well pump?

Depending on the equipment type and model, well pumps typically last anywhere from 8 to 15 years. However, several factors can contribute to the premature expiration of a well pump.

How long do submersible well pumps last?

The average life expectancy is 10 to 15 years for a residential 3-wire and 8 to 13 years for a residential 2-wire well pump.

Can I add a hand pump to my well?

If those wells aren’t too deep, hand pumps can be used as a back-up pumping option. … With a 6” well casing (the most common size) there’s plenty of room for the two pumps, and the portion of the Bison or Simple pump that is above-ground fits right onto the well casing, replacing the standard sanitary cap.

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 Christmas tree wellhead equipment?

What is a Wellhead? A wellhead skid controls the operation of the Christmas tree and mudline safety valves. The skid permits valves to be operated locally, remotely, or via ESD system and timing mechanisms provide a means of controlling the speed and sequence of valve operation.

What is Process Platform in offshore?

Offshore platforms are used to explore, extract, and process oil and gas retrieved from the seabed. One vital part of these structures is the central processing platform (CPP), where the well head fluid is pumped from the wellhead platforms through the riser for processing.

What is completing a well?

Well completion incorporates the steps taken to transform a drilled well into a producing one. These steps include casing, cementing, perforating, gravel packing and installing a production tree. … After a well has been drilled, should the drilling fluids be removed, the well would eventually close in upon itself.

Is there an essential oil that smells like a Christmas tree?

“Smells EXACTLY like a fresh cut Christmas tree. My entire family loves the scent. My kids even use it In their diffusers in their rooms.”

How does well head work?

Simply put, a wellhead is a system of spools, valves, and assorted adapters that used to provide pressure control of a production well. Its primary purpose is to provide a suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.

What is well header?

The Validated Well Header provides confidence in the data and allows you to see all of the well bores associated to a single hole in the ground, with detailed header information, orthorecified surface locations and verified ground elevations. An H-diagram provides a visual representation of the well system.

Why did the Deepwater Horizon blowout preventer fail?

The CSB concluded that the blowout preventer (BOP) failed because miswired control systems would have prevented it from sealing the blown-out well. A blowout preventer is a multi-ton stack of valves and pipes that sits atop deepwater wells to stop oil and gas from gushing upward in an accident.

What is an annular preventer?

An annular blowout preventer is a large valve designed to seal, control, and monitor oil and gas wells. These BOPs have elastomeric sealing, a valve resembling a large rubber donut, which mechanically squeezes inward to seal the drill string, casing, open hole, or pipe.

What is an annular on an oil rig?

1. n. [Drilling] The space between two concentric objects, such as between the wellbore and casing or between casing and tubing, where fluid can flow.
