What are the types of wellhead?
What are the types of wellhead?
Two types of wellhead chokes are used. They are (1) positive (fixed) chokes and (2) adjustable chokes. Placing a choke at the wellhead means fixing the wellhead pressure and, thus, the flowing bottom-hole pressure and production rate.
What is a wellhead platform?
Monopile wellhead platforms are a fast track, low risk and economic solution to developing marginal fields in benign and shallow water environments.
What is Unihead?
performance Uniheads® TechnipFMC’s structured and comprehensive portfolio delivers a broad set of standardised drilling products with cost and time efficient solutions, delivering the perfect balance of functionality and reliability for all our customers’ well applications.
What is the B section on a wellhead?
The second casinghead or “B” section goes above the bradenhead and is placed over the intermediate casing. Tubing Head. The third casinghead is placed over the production casing and supports the tubing string. It is the “C” section if placed on top of the intermediate spool or “B” section if on top of the bradenhead.
What are the components in well head?
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 well head equipments?
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. It forms an integral structure of the well.
What is a riser platform?
Offshore Platforms Production risers (which may be single or dual pipes and which range in diameter from 6 to 30 in.) provide the means for the crude oil and natural gas to flow from the ocean floor wellhead the production platform on the ocean surface.
What is CPP oil and gas?
CPP stands for Clean Petroleum Products which includes gasoline, heating oil, gas oil, naphtha and jet fuel. It is also known as Clean Oil. Gasoline. Gasoline can be extracted from the vapor of the petroleum when it is heated between 30 to 230 degrees Celsius.
What is swab valve?
On a Christmas tree, a swab valve is the topmost valve providing vertical access to the well for well intervention operations conducted by wireline, slickline, coiled tubing or a snubbing unit.
What is a wear bushing?
Retrievable cylindrical device that protects the internal surfaces of wellhead equipment and the top of the last casing suspended.
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.
What is casing valve?
Casing valves are part of a wellhead assembly and are placed right above where the well casing starts. The casing valve provides access to the space between these telescoped tubes (also known as the annulus space) and can prevent unwanted material and/or movement from occurring between the casings.
