What is a subsea wellhead?
The subsea wellhead system (Fig. 1) is a pressure-containing vessel that provides a means to hang off and seal off casing used in drilling the well. The wellhead also provides a profile to latch the subsea blowout preventer (BOP) stack and drilling riser back to the floating drilling rig.
What does Technip FMC do?
TechnipFMC plc (/ˈtɛkniːpɛfɛmsiː/ Tek-NEEP-ef-em-see) is a French-American, UK-domiciled global oil and gas company that provides complete project life cycle services for the energy industry.
How many types of wellheads are there?
Two types of wellhead chokes are used: positive (fixed) chokes and adjustable chokes. Placing a choke at the wellhead means fixing the wellhead pressure and thus the flowing bottom-hole pressure and production rate.
When did FMC merger with Technip?
TechnipFMC, created in 2017 through a merger between France-based Technip and U.S.-based FMC Technologies, announced its intention to separate into two independent public firms in August 2019 – one focused on upstream activities – Technip FMC – the other on midstream and downstream – Technip Energies.
What is the purpose of a wellhead?
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 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 are wellheads used for?
Where are wellheads located?
A wellhead is a component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.
Is Technip an EPC company?
ENOC announces Technip as main EPC Contractor for refinery expansion project – TechnipFMC plc.
What are the components of wellhead?
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. There are static and dynamic wellhead pressures.
How do well heads 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 does FMC mean?
At this time the company changed its name to Food Machinery Corporation, and began using the initials FMC. In 1948, the company name changed again, to Food Machinery & Chemical Corporation. In 1961, Food Machinery & Chemical Corporation was changed to simply FMC.
Is TechnipFMC a good investment?
Is TechnipFMC Stock Undervalued? Experts feel that a leaner, more simplified TechnipFMC is currently highly undervalued. The reason for it is not hard to decipher. The global pandemic led to a drastic fall in demand for oil, and investors are still apprehensive about an uptick in demand.
What are wellheads made of?
2.6. 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.
Where is the subsea wellhead system located?
The subsea wellhead system is located on the ocean floor, and must be installed remotely with running tools and drillpipe. Fig. 1—Illustration of a typical subsea wellhead system with temporary abandonment cap installed.
How many subsea wellheads has TechnipFMC installed?
We have installed more than 2,200 subsea wellheads, many of which are in service today. TechnipFMC’s track record of reliable equipment and forward-thinking innovation shows that we are the premier subsea wellhead system provider in the industry, while maintaining a world-class HSE record.
What is the mechanical behavior of a subsea wellhead?
A subsea wellhead is an important component that is placed at the mud line. Some scholars have studied the loads and stability of subsea wellheads; for example, Su (2009) analyzed the mechanical behaviors of risers and subsea wellheads. Methods have been established to calculate the bending moment, axial force and lateral force on the wellhead.
What is a subsea high-pressure wellhead housing?
The subsea high-pressure wellhead housing (typically 18¾ in.) is, effectively, a unitized wellhead with no annulus access. It provides an interface between the subsea BOP stack and the subsea well.
