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 .
