What is a slip RAM?
Slip Rams are devices that are used to hold and secure the coiled tubing in a wellbore in place. The rams support the weight of the tubing as well as the bottom hole assembly.
What is blind shear ram?
A blind shear ram is the thick, heavy steel component of a ram blowout preventer (BOP). Blind shear rams are always fitted with hardened tool steel blades designed to cut the tubing or the drill pipe when the BOP is closed. It then fully closes to isolate or seal the wellbore completely.
How much does a blowout preventer weigh?
A blowout preventer, or BOP, is a large specialised unit weighing up to 400 tonnes that is used to prevent an oil spill from occurring.
How does a blowout preventer work?
Essentially, a blowout preventer (BOP) shuts off the valve leading underneath the machinery to stop any liquid from surfacing in a dangerous explosion, or a kick. A level of containment must be maintained when working with the mud and substances that could cause breaks in the flow of extraction.
What is annular preventer?
An annular blowout preventer is a large, specialized valve used to seal, control and monitor oil and gas wells. It is usually installed above the ram preventers that forms a seal in the annular space between the pipe and wellbore or, if no pipe is present, over the wellbore itself.
What do blind rams do?
Blind Ram – Function of blind ram is to cut off the opening for tubing or drill string when no production is going on from a well. Shear Ram – Function of shear ram is to seal the wellbore even if there’s a tubing or drill string inside by cutting through the pipe.
How many types of BOP are there?
There are three main categories of the BOP: the current account, the capital account, and the financial account. The current account is used to mark the inflow and outflow of goods and services into a country. The capital account is where all international capital transfers are recorded.
What is the difference between BOP and Christmas tree?
The Wellhead Versus the Christmas Tree The Christmas tree is sometimes confused for the wellhead of an oil well. The Christmas tree sits atop the wellhead, but it is a separate piece of equipment. There is no Christmas tree on the wellhead during drilling operations.
What is the equipment design to prevent kick and blowout?
The blowout preventer (BOP) equipment on a rig serves as a backup to the mud system in controlling kicks and subsequent blowouts. Well kicks are prevented by maintaining the hydrostatic pressure of the drilling fluid greater than the formation pressures that are exposed to the wellbore.
What is the difference between a kick and a blowout?
This forced fluid flow is called a kick. If the flow is successfully controlled, the kick is considered to have been killed. An uncontrolled kick that increases in severity may result in what is known as a “blowout.”
What causes a well blowout?
An oil well blowout is an uncontrolled release of crude oil. Blowouts occur when pressure release systems fail. They can also occur if a spark or flame contacts the oil or for other reasons. Oil well blowouts cause death and catastrophic injuries to workers near the scene of a blowout.
What is a HCR valve on a drilling rig?
Drilling & Operations. Remarks: The HCR valve is a hydraulically operated gate valve. This valve is used on diverter systems and choke/kill lines leading from the blow out preventers. The advantage of the valve is that it can be operated remotely.
What are slip Rams and what do they do?
Definition – What does Slip Rams mean? Slip Rams are devices that are used to hold and secure the coiled tubing in a wellbore in place. The rams support the weight of the tubing as well as the bottom hole assembly.
What do slip rams do in a wellbore?
Slip Rams are devices that are used to hold and secure the coiled tubing in a wellbore in place. The rams support the weight of the tubing as well as the bottom hole assembly.
What does a slip Ram do in an oil well?
Slip ram is used to hold and secure the coiled tubing when it is being injected down into an oil or gas well against high fluid pressure during oil and gas well intervention processes. The slip ram is an element of a blowout preventer and is equipped with bidirectional teeth to hold the coil tubing and prevent its movement.
