A Wellhead is
the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment
. … Our Well Head Platforms were a custom design project that became an industry wide standard for Generator Access!
What is well head in drilling?
A Wellhead is
a structure that is installed at the top of a natural oil or gas well
. Its main function is to ensure a safe operation and manage the flow of oil or gas from the well into the gathering-system.
What is wellhead deck?
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 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 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 does well head do?
The
system of spools, valves and assorted adapters that provide pressure control of a production well
. The surface termination of a wellbore that incorporates facilities for installing casing hangers during the well construction phase.
What is the purpose of well head?
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 riser platform?
A drilling riser is
a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility
.
What means cellar deck?
noun.
The lowest platform level on an offshore drilling rig
.
What is a platform jacket?
Description. The steel jacket type platform on a pile foundation is by far the most
common kind of offshore structure
and they exist worldwide. … The piles are thick steel pipes of 1 to 2 metres diameter and can penetrate as much as 100 m into the sea bed. The jacket can weigh up to 20,000 tonnes.
What is unmanned platform?
Unmanned offshore platforms are
designed to be operated remotely without onsite personnel
. The day-to-day operations of these platforms, which are smaller than manned platforms, are controlled either by onshore teams or via a neighbouring platform.
What is the function of Christmas tree?
A Christmas tree is a piece of equipment that
provides flow control on a oil or gas well
. Christmas trees are a vertical assembly of valves with gauges and chokes that allow for adjustments in flow control as well as injections to stimulate production.
What is a subsea Xmas tree?
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
.
What is Sssv valve?
The
tubing-retrievable subsurface safety valve
(SSSV) provides well protection against pressure drop and system failure in wireline and thru-tubing operations. This retrievable safety valve is controlled from the surface with a hydraulic control line.
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
.
How much is a well head?
| State Average Cost Per Foot | California $30 – $65 | Colorado $28 – $62 | Connecticut $30 – $66 | Delaware $29 – $63 |
